Da, on je imal "problem s 5995WX procesorom" na temelju dvije sfušane ploče, a za zadnju ASUS kombinaciju je rekel da je radilo, ali nakon svega mu je već bilo dosta pizdarija.

Pa šta nije za Asusa rekao da ne rade nV grafe i/ili da su performanse osjetno slabije i da je probao to popeglati i da je odustao nakon nekog vremena.

@Lewis: Si uzeo tog TR-a i koliko komada?

AMD EPYC Turin CPUs up to 128 Zen 5 or 192 Zen 5c cores

Citiraj:

AMD EPYC Turin will be the 5th Gen EPYC lineup that replaces the 4th Gen EPYC family. The 4th Gen EPYC family is comprised of Genoa, Genoa-X, Bergamo & Siena CPUs which make use of Zen 4 & Zen 4C cores in EPYC 9004/8004 SKUs. The 5th Gen EPYC family will be similar, featuring a range of configurations and SKUs with Zen 5 "Nirvana" & Zen 5C "Prometheus" cores. The Zen 5 cores are expected to utilize the 3nm process node while Zen 5C may utilize the same or optimized variant. AMD EPYC Turin CPUs with Zen 5 Classic cores will offer up to 128 cores and 256 threads. There will be a maximum of 16 CCDs with 8 cores each, and each CCD will come with its own 32 MB of L3 cache. This will form up to 512 MB of L3 cache. This marks a 33 percent increase in core count and 33 percent increase in the total L3 cache count versus the Zen 4 based EPYC Genoa family.

AMD EPYC Turin CPU featuring the Zen 5C cores is where things get crazy with each Zen 5C CCD offering up to 16 cores and 32 MB of L3 cache. There will be six compute chiplets onboard these chips for a total of 192 cores and 384 threads with a slightly reduced 384 MB of L3 cache. The CPUs will retain the same I/O as the other classic chips. Compared to AMD's EPYC Bergamo CPUs based on the Zen 4C cores, the Turin chips with Zen 5C cores will offer a 50% increase in the number of cores and threads (192/384 vs 128/256) while offering the same uplift of 50% in the total cache count (384 MB vs 256 MB). Both Zen 5 & Zen 5C chips are expected to feature TDPs of 480W which can be configured up to 600W. The increase in computing capabilities will mark an incremental path to existing servers who can just drop in these chips on existing platforms and enjoy the added boost.

AMD 5th Gen EPYC Turin CPUs launched: Up to 37% IPC increase, up to 192 Cores, 500W TDP, 5.0GHz clocks & significantly outperforming Xeon

Citiraj:

For its 5th Gen EPYC lineup, there are going to be two solutions. The 4nm version of Turin with up to 16 "Zen 5" CCDs, offering up to 128 cores and 256 threads, which is referred to as the "Scale-Up" variant while the second one is the "Scale-Out" variant which utilizes the 3nm "Zen 5C" cores with up to 12 CCDs, offering up to 192 cores and 384 threads. Turin packs up to 17 chiplets with a total of 150 Billion transistors for the full chip. The CPUs will come with AVX-512 support with a full 512b data path & up to 5 GHz clock speeds. Chips can be configured in 1P or 2P servers. In terms of IPC improvement, AMD states that Zen 5 delivers "exceptional uplifts" over the previous generation with up to a 17% increase for Enterprise and Cloud platforms and up to a 37% increase for HPC and AI platforms. The lineup scales from 8 cores to up to 192 cores and TDPs scale from 155W to up to 500W. As for the platform itself, AMD is relying on the same SP5 socket for both variants of Turin which makes it an easy drop-in upgrade from the previous Genoa and Bergamo "Zen 4" releases.

The platform still offers a 12-channel memory solution but now has DDR5 speeds configured up to 6400 MT/s with ECC support, 6 TB capacities per socket & you still get 128 PCie 5.0/CXL 2.0 lanes. New on Turin is support for PPR or Dynamic Post Package Repair for x4 and x8 ECC RDIMMs. On the security front, you get Trusted I/O, FIPS 140-3 in process, and Hardware Root-of-Trust support. The 5th Gen AMD EPYC "Turin" lineup will consist of a total of 27 SKUs which include the EPYC 9965 as the 192-core "Zen 5C" flagship, the EPYC 9755 as the 128-core "Zen 5" flagship, and the EPYC 9575F "Zen 5" chip as the first 5 GHz EPYC SKU. Moving to the details of the flagship SKUs, the AMD EPYC 9965 will feature 192 cores, 384 threads, and 384 MB of L3 cache. This chip will feature a 2.25 GHz base clock and a 3.7 GHz boost clock. The CPU will be configured at a default TDP of 500W and will be priced at $14,813 which is significantly lower than Intel's top Xeon 6900P offering which is priced at $17,800 US. That's a 17% higher price for Intel's flagship offering with 128 cores.

The EPYC 9755 which is based on the standard Zen 5 cores will come configured with 128 cores, 256 threads, 512 MB of L3 cache, a base clock of 2.7 GHz, a boost clock of 4.1 GHz, and a TDP of 500W. This chip will feature a price of $12,984 US which is again much lower than Intel's 6980P chip, marking a -27% difference. AMD also has several frequency-optimized variants in 64, 48, 32, 24, and 16 core flavors. The top part is the EPYC 9575F which offers 64 cores, 128 threads, 256 MB of L3 cache, a 400W TDP, a base clock of 3.3 GHz, and a boost clock of 5.0 GHz. This chip is priced at $11,791 US. Lastly, we should mention the entry-level 8-core SKU, the EPYC 9015, which is configured with a 125W TDP and has a base clock of 3.6 GHz, and a boost clock of 4.1 GHz and 64 MB of L3 cache. This chip will cost $527 US.

AMD is also outlying its EPYC platform to be used as an AI Host CPU for AMD Instinct and nVidia MGX/HGX platforms. The solution can be equipped with up to 8 OAM MI300X or MI325X GPUs & configurations that use the EPYC 9575F 5 GHz chip and can see up to a 20% performance increase in AI inferencing and up to 15% uplift in training. For nVdiia, the MGX solutions can be equipped with up to 16 AI accelerators (Hopper/Blackwell) and HGX configurations can get up to 8 accelerators with up to 2 EPYC CPUs. AMD & nVidia have announced a technical partnership, recommending a range of EPYC CPUs ranging from 32, 48, and 64 cores.

AMD EPYC 9755 / 9575F / 9965 Benchmarks Show Dominating Performance

AMD EPYC 9005 Turin Turns Transcendent Performance with 768 Threads Per Server

AMD EPYC 9965 "Turin Dense" Delivers Better Performance/Power Efficiency vs. AmpereOne 192-Core ARM CPU

Citiraj:

The tested AMD EPYC 9575F high frequency Turin 64-core processor, EPYC 9755 128-core Turin processor, and EPYC 9965 192-core Turin Dense processors dominated across the wide variety of server / technical computing / HPC workloads tested. The dual 128-core EPYC 9755 Turin processor was 40% faster than the dual Xeon 6980P Granite Rapids server with MRDIMMs. Even a single EPYC 9755 (and EPYC 9965) effectively matched the dual Xeon 6980P processors in this larger selection of benchmarks than what was initially run for Granite Rapids. The EPYC 9755 flagship Turin (non-dense) processor was 1.55x the performance of the 96-core EPYC 9654 Genoa processor. The EPYC 9965 192-core Turin Dense processor was 45% faster as well than the dual EPYC 9754 flagship Bergamo processor. These are some wild generational improvements.

Across all of the benchmarks, the EPYC 9965 had an average CPU power consumption of 275 Watts and a peak of 461 Watts, the EPYC 9575F had an average of 313 Watts and a peak of 403 Watts, and the EPYC 9755 had an average power consumption of 324 Watts with a peak of 500 Watts. The Xeon 6980P meanwhile had a 322 Watt average and 547 Watt peak. The tested AMD EPYC 9005 series processors delivered excellent generational performance gains over the EPYC 9004 series, leading performance over the new Xeon 6900P Granite Rapids series, and completing the trifecta is leading performance-per-dollar as well. The EPYC 9755 has a list price of $12,984 and the EPYC 9965 192-core processor has a list price of $14,813 while the Xeon 6980P has a list price of $17,800. There is significant savings in going for EPYC 9005 series.

AMD’s X3D V-Cache tech is coming to Threadripper and next-gen APUs

Citiraj:

Following reports of AMD’s plans for Ryzen Threadripper X3D CPUs, another source has confirmed the existence of this V-Cache-enhanced monster CPU range. AMD’s 3D V-Cache technology is coming to other next-generation AMD products. Regarding Threadripper, CCDs on AMD’s X3D CPUs will be “all stacked”. This means that all CCDs on AMD’s Ryzen Threadripper X3D CPUs will feature 3D V-Cache. This makes sense now that AMD has been able to achieve higher clocks speeds with their latest X3D CPUs. With AMD’s next-generation “Halo-level” APUs, AMD will reportedly add its 3D V-Cache to boost the performance of its CPU and GPU components. This makes sense, given these products’ often bandwidth-starved nature.

Adding 3D V-Cache to AMD’s next-generation version of “Strix Halo” would be a great move for AMD to make. After all, this chip would aim to deliver discrete-level GPU performance and high-end CPU performance within a single mobile-friendly package. AMD’s Strix Halo APU will reportedly launch in 2025 with 16 Zen 5 CPU cores and an RDNA 3.5 GPU with 40 compute units. The GPU is said to deliver performance levels similar to those of an RTX 4070 (mobile), and its next-generation counterpart should be even stronger. As mentioned before, AMD’s APUs are often bandwidth-starved. While AMD’s X3D V-Cache technology is often used to deliver performance gains through decreased data access latencies (accessing data on cache is orders of magnitude faster than accessing data on DRAM), it also frees up bandwidth on higher-level memory pools.

Adding 3D V-Cache to an APU will free up system memory bandwidth, which could be used elsewhere. This makes AMD’s X3D technology doubly beneficial. It will give their next-gen “Halo” APUs the same X3D benefits as existing CPUs. Furthermore, it will free up bandwidth that can speed up other areas of the SOC. With this X3D APU, AMD could use V-Cache on just the CPU (or GPU), on both the CPU and GPU (separately), or on both using a shared X3D cache. Regardless of what way AMD uses it, it will boost overall SOC performance. That’s good news for AMD, and their future laptop customers.

AMD crafts custom EPYC CPU with HBM3 memory for Microsoft Azure – CPU with 88 Zen 4 cores and 450GB of HBM3

Citiraj:

The custom AMD CPU used for HBv5 VMs leverages HBM3, usually the memory of choice for the latest data center-class GPUs, such as AMD’s MI300X. With a bandwidth of 6.9TB/s from four of the chips in a single VM, the VMs are almost nine times faster than the Genoa-X CPUs that Microsoft offers in HBv4 VMs, and nearly 20 times faster than Milan-X chips in HBv3 VMs. When paired with a CPU, the HBM3 fulfills a similar role as 3D V-Cache. Still, instead of expanding the pool of L3 cache, it effectively adds a massive L4 cache with even greater bandwidth and presumably much worse latency. However, the latter isn't as important in certain types of workloads.

Unlike Intel with the Xeon Max CPUs, AMD has not yet had an EPYC processor with HBM. The Azure HBv5 VM should be able to offer 6.9 TB/s of storage bandwidth. However, this does not consist of just one processor; Microsoft specifies 352 Zen 4 cores with a clock speed of up to 4 GHz. Each core should have up to 9 GB available and the mentioned 6.9 TB/s will be achieved in the STREAM Triad on 400 to 450 GB of HBM3. SMT is disabled and there is only one VM per server, so multiple VMs do not have to share the hardware. Apparently the EPYC processors with HBM were in development at AMD as Instinct MI300C. The model name is EPYC 9v64H.

AMD Threadripper 9000 series spotted: 96-core Zen 5 CPUs on the horizon

Citiraj:

AMD's Threadripper lineup continues to deliver high-performance processors for enthusiasts and demanding workstation users. The company is sticking with the same successful formula for the upcoming Threadripper 9000 series, codenamed "Shimada Peak." These new chips have been spotted in shipping manifests, providing an early look at core configurations and more. The shipping manifest, reveals that AMD is preparing 96-core, 64-core, 32-core, and 16-core variants for the Threadripper 9000 series. Notably, all the listed SKUs share a 350W TDP, which is identical to the "Storm Peak" CPUs they are likely set to replace.

At the top of the lineup is the 96-core, 192-thread powerhouse, featuring a massive 12 CCDs, each with eight cores and 32MB of L3 cache. This adds up to a total of 384MB of L3 cache. The design closely mirrors that of the existing Threadripper Pro 7995WX processor. However, the efficiency and performance gains from the Zen 5 architecture, coupled with a newer TSMC process node, offer significant improvements. Expect better performance-per-watt compared to the Zen 4 chips. At the other end of the spectrum is the 16-core variant, which features dual 8-core CCDs, delivering substantial power for tasks that require high single-thread and moderate multi-thread performance.

Overall, the Shimada Peak series' core configurations appear to be tailored to meet the needs of a broad range of users, from professionals seeking maximum parallel processing power to enthusiasts looking for more mainstream options. AMD's commitment to supporting the sTR5 socket for at least two generations is a welcome move, as previous socket transitions haven't always been this user-friendly. This compatibility offers a degree of future-proofing for those investing in such a high-end platform. That said, AMD has not yet officially confirmed the Threadripper 9000 series, but these leaks align with rumors pointing to a launch later this year.

AMD Threadripper Pro 9000 CPUs leak in shipping logs, suggesting imminent launch

Citiraj:

AMD's Threadripper Pro 9000 series, the next generation of its high-performance workstation CPUs, has made an appearance on shipping manifests, hinting at an imminent launch. These logs have revealed key details about two of the upcoming models: the Threadripper Pro 9975WX and 9965WX. The processors are based on AMD's new Zen 5 architecture and expected to introduce significant upgrades while maintaining compatibility with existing platforms. The leaks confirm the existence of the 32-core Threadripper Pro 9975WX and the 24-core Threadripper Pro 9965WX. Both CPUs will feature hyperthreading, with 64 and 48 threads, respectively. This aligns with their predecessors in the Threadripper Pro 7000 series, which also offered the same core and thread configurations. However, the new models will benefit from the Zen 5 architecture, promising improved performance and efficiency.

One notable constant is the thermal design power (TDP), which remains at 350W for both models. This matches the wattage of the current-gen Threadripper Pro 7000 series, ensuring drop-in compatibility for existing systems. Beyond these two models, the Threadripper Pro 9000 series is expected to feature five models in all, ranging from 16 to 96 cores. Chips including a flagship 96-core/192-thread Threadripper Pro 9995WX, a 64-core/128-thread 9985WX, and a 16-core/32-thread 9955WX have previously been spotted. Interestingly, AMD may skip the 12-core variant this time.

Under the hood, the Zen 5 architecture brings a smaller 4nm process node, offering better power efficiency compared to the 5nm node used in the Threadripper 7000 series. Each Zen 5 core complex die (CCD) packs eight cores and 32MB of L3 cache, meaning the 32-core 9975WX will utilize four CCDs, while the 96-core 9995WX will house a whopping 12 CCDs and 384MB of L3 cache. This cache structure mirrors the current generation, suggesting no major changes in this area. That said, while the leaks provide a glimpse into AMD's plans, it's important to note that shipping manifests are not official sources. AMD has yet to confirm the lineup or announce a release date. But the mere appearance of these logs hints that an official launch could be just around the corner.

ASUS confirms Ryzen Threadripper 9000 series with up to 96 cores

Citiraj:

The Threadripper 9000 series, codenamed Shimada Peak, support was recently introduced for the Gigabyte TRX50 motherboard series. It seems ASUS is following suit by confirming the name of the series directly. As expected, the new Zen 5 series will be a drop-in replacement for the Zen 4 generation, retaining the same package and socket support. The latest SKU lists confirm five variants featuring 12 to 64 cores. It is almost certain that AMD will also launch a 96-core version, matching the core count of the previous series (Storm Peak). These CPUs will be a drop-in replacement for the sTR5 socket and will maintain the same 350W TDP. The word is that Threadripper will be part of the Computex 2025 showcase. AMD has a press event planned where they promised product announcements for gaming and professional markets.

AMD EPYC 9006 “Venice” to feature up to 96 Zen6 or 256 Zen6c cores, 128MB L3 cache per CCD

Citiraj:

The EPYC Venice series is said to come in two variants, specifically for the SP7 and SP8 sockets. The latter is said to be limited to 128 Zen6c or 96 Zen6 cores with a 350-400W TDP, while SP7 would feature up to 256 cores (so only Zen6c implementations) and an even higher TDP of 600W. Each CCD packs 12 Zen 6 cores, and there are multiple IODs in the middle, which would lead to further expansion of I/O capabilities on these server platforms. It is not reported if the 128 MB L3 cache is for the Zen 6 or Zen 6C variants, but for a Zen 6C EPYC chip, which gives us 2 MB of L3 per core. As for the EPYC 9006 "Zen 6" SKUs, they will have up to 96 cores and 192 threads with up to 8 CCDs as reported above, while Zen 6C variants will scale up to 256 cores and 512 threads.

AMD Announces Ryzen Threadripper 9000 and PRO 9000 WX-Series

Citiraj:

AMD announced its new Zen 5-powered Ryzen Threadripper Pro 9000 WX-series and non-Pro processors here at Computex 2025 in Taipei, Taiwan, touting up to 96 cores and 192 threads in the flagship 9995WX. AMD's newest 'Shamida Peak' Threadrippers bring the benefits of the Zen 5 architecture to AMD's premier WX-Series workstation and non-Pro processors, saying they deliver up to 2.2X the performance in rendering than Intel's fastest competing Xeon-W chips. AMD also revamped its non-Pro Ryzen Threadripper 9000-series chips, with the flagship 9980X HEDT chip wielding 64 cores and 128 threads. AMD's full Threadripper 9000 series will be available in July.

The Threadripper 9000 chips have much in common with their predecessors, the Threadripper 7000 series, with AMD continuing to split the chips into the Pro and HEDT swimlanes. The chips also have the same core counts, base clocks, and cache capacities (up to 384MB) as the prior-gen models across the range of the product stack, but the peak boost clocks have been bumped up to 5.4 GHz for all models, an increase ranging from 100 to 300 MHz. The TDP ratings also remain the same 350W for all models. The processors provide up to 22% more performance than the prior-gen in threaded workloads, and the lion's share of their increased performance from the jump from the Zen 4 architecture to Zen 5, which imparts a 16% IPC gain, and the move from 5nm to 4nm for the compute dies.

Both families of Threadripper 9000 chips will drop into the same sTR5 socket as the prior-gen chips. The WR90 platform with support for eight channels of memory will house the Pro chips, while value-optmized TRX50 boards with support for four channels of memory house the HEDT processors. After a BIOS update, the new chips are compatible with existing motherboards. AMD expects a few new refreshed motherboard models from vendors, but it says the chips will largely leverage the existing ecosystem of sTR5 motherboards. As such, all of the existing sTR5 coolers on the market are fully compatible with the new processors.

AMD Ryzen Threadripper 9000: Up to 26% more performance than its predecessor for July launch

Citiraj:

Last month at Computex was the original Threadripper 9000 series announcement ahead of the planned July launch. Back then they shared the general features of these next-gen HEDT processors as well as the SKU tables for the AMD Ryzen Threadripper 9000 series and Threadripper PRO 9000 WX-Series. At last week's briefing they shared some additional details and benchmarks on these high-end desktop/workstation processors set to ship in July. For workstation benchmarks AMD is talking up around a 16% generational uplift for the Ryzen Threadripper 9000 series compared to prior generation Threadripper 7000 series. For AI and machine learning workloads they are talking up 25% gains, which isn't too surprising given what we have seen out of AMD EPYC Turin and particularly because of the AVX-512 with a full 512-bit data path on Zen 5 able to provide significant benefits for AI/ML and other HPC workloads. AMD did not yet reveal pricing for these Threadripper 9000 / Threadripper PRO 9000 WX-Series processors that are expected to be available next month.

The Ryzen Threadripper 9000 series comes with CPU core counts of up to 96-core/192-thread, with an IPC uplift from the "Zen 5" microarchitecture over the previous Threadripper 7000 series "Storm Peak" processors powered by "Zen 4." More than IPC, workstation users should benefit greatly from the architecture's full 512-bit FPU data-path, offering significant increases in performance of applications that leverage the AVX-512 instruction set. AMD also fine-tuned the IOD (I/O die) to support increased memory speeds of DDR5-6400 (native), AMD EXPO profiles, and CKD. The Ryzen Threadripper 9000 series "Shimada Peak" package is designed for AMD Socket TR5, and is drop-in compatible with all TR5 motherboards with the latest UEFI firmware updates. AMD mandates USB BIOS Flashback feature for all its workstation and server platforms. The processor comes with an 8-channel DDR5 memory interface (16 sub-channels), with ECC DDR5-6400 native speeds, support for AMD EXPO tested for over 7000 MT/s, and memory interleaving for 2-, 4-, 6-, or 8-channel. The memory interface also supports RDIMMs, although the platform is capped at 1 DIMM per channel, and a maximum memory size of 2 TB.

The SoC I/O features sees a massive 128-lane PCI-Express 5.0 root complex, which lacks the CXL features you find in EPYC "Turin" processors. SoC topology changes sees the PCIe aggregate bandwidth improve over "Storm Peak." Other features include AMD PRO Management features, and AIM-T WLAN support. AMD also unveiled its smaller lineup of Threadripper 9000X HEDT processor series. These are targeted at HEDTs and entry-level workstations. The key difference with the PRO 9000 WX series is the lack of AMD PRO features, and a truncated I/O feature-set that includes 4-channel (8 sub-channel) DDR5 memory, and a reduced 48-lane PCI-Express 5.0 root complex. There are only three SKUs, ranging from 24-core/48-thread, to 64-core/128-thread. These chips are compatible with Socket TR5 motherboards, too, however, half the memory channels and some PCIe/NVMe slots will be disabled or reconfigured—the motherboard manual will tell you which ones.

Intel Xeon 6300 vs. AMD EPYC 4005 SMT/HT performance

Citiraj:

While the latest Intel Core Ultra processors have done away with Hyper Threading (HT), Intel Xeon CPUs continue supporting HT/SMT, including with their latest Xeon 6300 series budget server processors. As the new AMD EPYC 4005 "Grado" processors also support Simultaneous Multi-Threading (SMT) and can be found at the same core/thread count count as the flagship Xeon 6369P processor, it makes for an interesting look at comparing the SMT/HT performance impact and power efficiency. For making this SMT/HT comparison as 1:1 as possible, the AMD EPYC 4345P was used that is an 8-core / 16 thread CPU like the Xeon 6369P.

At the same core counts, the Zen 5 based AMD EPYC 4005 series was showing greater benefit out of SMT than the flagship Xeon 6300 series processor. Also fascinating to see was that the AMD EPYC 4345P even with SMT disabled was still faster than the Xeon 6369P with its full load-out thanks to the EPYC Grado CPU supporting AVX-512 and other advantages over the Xeon 6300 series that in turn is largely rehashed from the Xeon E-2400 series. Across all 69 benchmarks in total, there wasn't any significant CPU power consumption difference for either the EPYC 4345P or Xeon 6369P. The EPYC 4345P was not only delivering better performance over the Xeon 6369P but it was doing so at lower power: 82 Watts on average compared to the Xeon 6369P at a 93 Watt average and a peak power consumption rate more than double.

AVX-512's enormous advantage on AMD EPYC 4005 series performance

Citiraj:

With the AMD EPYC 4005 series there is up to 16 cores / 32 threads unlike the Xeon 6300 series with its 8 core / 16 thread max, DDR5-5600 ECC memory support compared to DDR5-4800, the "PX" SKUs for 3D V-Cache, and then AVX-512 being one of the significant architectural advantages with these lower-cost Zen 5 server processors. AVX-512 with the EPYC 4005 series can be of enormous benefit to Advanced Vector Extensions 512 capable workloads, as shown in tests as well with the EPYC 9004/9005 series and AMD Ryzen 7000/8000/9000 series too. Even without AVX-512 being enabled, the EPYC 4345P 8-core processor was still surpassing the Xeon 6369P competition while in its standard load-out configuration easily whoops that Xeon E-2400 series successor while the EPYC 4585PX performance is in a whole separate ballpark.

There are many workloads these days that can benefit from AVX-512 support -- much more so than when Advanced Vector Extensions 512 was first introduced by Intel. Many of Intel's own oneAPI software packages benefit significantly from AVX-512 and thus left in a situation where the AMD EPYC 4005 series is the much better buy for performance and power efficiency than their own Xeon E or Xeon 6300 series CPUs. Unlike the early days of Intel CPUs with AVX-512 that gave Advanced Vector Extensions a bad introduction due to high power use and poor thermals, that hasn't been the case with AMD's Zen 4 and Zen 5 implementations.

When looking at the CPU power numbers across all of the benchmarks conducted, there was no real difference for either the EPYC 4345P or EPYC 4585PX in the CPU power draw with/without AVX-512. AMD's AVX-512 implementation has continued to be remarkably efficient from Ryzen and bigger EPYC CPUs to now with the EPYC 4005 series confirmation too.
