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

AMD Ryzen Threadripper 9000 preorders start July 23: 96-core PRO 9995WX listed at $13,000:fiju:
Citiraj:

AMD will lift the embargo on Threadripper 9000 series preorders on July 23. This date has been listed by B&H Photo Video, one of AMD’s retail partners for this launch in the US. Importantly, this date applies to both the Threadripper 9000X and PRO 9000WX series, so a total of seven SKUs will go on sale that day. B&H Photo Video does not officially list any prices, as these are preorders. However, users can easily estimate the prices by selecting price ranges and checking which SKUs appear. We went through the list and came up with the following pricing. So overall, we are looking at a 4% to 30% price increase per SKU. The cheapest variants are for the HEDT market, covering 24, 32, and 64 cores (4% to 7% increase), while the PRO series has seen a much higher price increase of 13% to 30%. The flagship 96-core SKU, which according to AMD delivers a 26% generational upgrade, has received almost the exact same price change. Naturally, these prices are not official, and we are not sure if B&H even realizes that people can view them this way. However, the 30% price increase has already appeared at other stores, so it seems we might have the full picture now.
  • Ryzen Threadripper 9960X 4.2 GHz 24-Core: $1,600 (+7% vs. 7960X)
  • Ryzen Threadripper 9970X 4.0 GHz 32-Core: $2,600 (+4% vs. 7970X)
  • Ryzen Threadripper 9980X 3.2 GHz 64-Core: $5,300 (+6% vs. 7980X)
  • Ryzen Threadripper PRO 9965WX 4.2 GHz 24-Core: $3,100 (+17% vs. 7965WX)
  • Ryzen Threadripper PRO 9975WX 4.0 GHz 32-Core: $4,400 (+13% vs. 7975WX)
  • Ryzen Threadripper PRO 9985WX 3.2 GHz 64-Core: $8,500 (+16% vs. 7985WX)
  • Ryzen Threadripper PRO 9995WX 2.5 GHz 96-Core: $13,000 (+30% vs. 7995WX)

Fino su se razbahatili, k'o intel nekada, dizanje cijena na jako :).

The Exiled 14.07.2025. 15:18

Je, a najgore je kaj znaju da se bude prodalo, jer je EPYC Turin dal do znanja kaj krajnji korisnici mogu očekivati sa Zen 5 Threadripperom.

Moguće da se finalne cijene malo korigiraju u odnosu na ove izlistane po cjenicima, ali kak god se okrene, cifre su im popularne.:)

AMD Ryzen Threadripper PRO 9000WX Content Creation Review:kafa:
Citiraj:

In traditional “media and entertainment” workflows with applications like Photoshop, Premiere Pro, After Effects, and DaVinci Resolve, the new Threadripper PRO 9000WX CPUs offered good generational improvements. In nearly all of those applications, we saw uplifts of 15-25% in CPU-bound scenarios. However, even in traditional GPU workloads, like GPU Effects in Premiere Pro or LongGOP processing in DaVinci Resolve, the 9000WX processors increased performance by around 5% over the 7000WX processors. In many cases, a desktop Ryzen (or Intel Core Ultra) processor may still be a better value for these workflows, so we’d recommend checking out reviews of those parts as well. However, if you need a Threadripper PRO processor for the high RAM capacity, huge number of cores, or high PCIe lane count, they certainly won’t detract from your ability to do work in these applications.

For heavily CPU-based applications like CPU Rendering in V-Ray, Blender, or Redshift, or compiling code and scenes for Unreal Engine, the Threadripper PRO 9000WX family is even more impressive. The 9995WX is the new king of workstation CPU rendering, outperforming the 7995WX by up to 27% and Intel’s top-end Xeon by up to 125%. We saw average generational performance improvements of 26% in Cinebench, 15% in Blender, and 22% in V-Ray. AMD’s latest update to its Ryzen Threadripper PRO line is very impressive, offering great performance at a modest price increase. While we would have liked to see the price stay constant, the drop-in compatibility with existing WRX90 platforms should hopefully reduce the sting of the already-expensive CPUs. We are particularly impressed that AMD managed to dramatically improve memory support, with the new processors officially supporting DDR5-6400.

AMD Ryzen Threadripper 9000X for enthusiasts launches July 31, 64-core 9980X costs $5000:fiju:
Citiraj:

Perhaps the biggest question right now is, what is a HEDT (High-End Desktop) system? In the past, such SKUs were undoubtedly expensive, but it took a few years for prices to reach not just hundreds but thousands of dollars. The Core i7-6900/6800K/X family released nine years ago already had the 6950X priced at $1,723, so should it be surprising to see modern HEDT CPUs costing thousands of dollars?

While Intel has shifted its focus toward professionals and workstation builders, AMD still offers a Threadripper line dedicated to enthusiasts. These non-PRO SKUs are priced lower than their PRO counterparts and target content creators and enthusiasts who enjoy overclocking. The PRO series also supports overclocking, as shown by what the flagship $11,000 9995WX is capable of.

The Threadripper 9000X series is designed for TRX50 motherboards, which support 4-channel memory and up to 92 PCIe lanes. Users on this platform will also have access to overclocking support. Starting July 31, three SKUs featuring 64, 32, and 24 cores will be available in the DIY market (not limited to OEMs). While there are currently no listings for these CPUs, AMD has confirmed the following pricing:
  • AMD Ryzen Threadripper 9980X (64c / 128t): $4,999
  • AMD Ryzen Threadripper 9970X (32c / 64t): $2,499
  • AMD Ryzen Threadripper 9960X (24c / 48t): $1,499
As a result, the 9980X features the same core count as the 9985WX but costs $3,000 less. For users who don’t need PRO features, this is an easy choice. The same applies to the 32-core variant, which is $1,600 cheaper, and the 24-core version, which also comes with a significant $1,400 price gap compared to its WX counterpart.

AMD Threadripper 9980X + 9970X Linux benchmarks: Incredible workstation performance:kafa:
Citiraj:

Citiraj:

When taking the geometric mean of all the raw performance data points in full, going from the Threadripper 7980X to 9980X yielded a 30% improvement. For a single generation. Some of my numbers have been relatively even higher than shown by AMD with all of their Microsoft Windows 11 results. Meanwhile for the 32-core Threadripper 9970X there is a similar 28% improvement over the prior-generation Threadripper 7980X. Simply great performance. ~30% generational performance improvements alone are great but it's even a more compelling case when looking at the CPU power numbers.

Across the span of all the benchmarks conducted, the Threadripper 9980X had a 287 Watt average to the 7980X at a 309 Watt average. Both had a peak power draw at 370~372 Watts. Meanwhile the 9970X CPU power use had a 296 Watt average compared to the prior generation 7970X at 286 Watts. Roughly put, similar CPU power usage but being able to deliver 28~30% higher performance on average going from the Threadripper 7000 to 9000 series processors. And drop-in compatibility with BIOS update for existing Threadripper 7000 series workstations.

CVE-2024-21944 - https://badram.eu/

Kakva su vam iskustva sa SEV?

IMHO ova tema je primjerenija za BadRAM.:)
Citiraj:

Citiraj:

The BadRAM attack – which does require physical access to hardware (for example, a rogue admin scenario) – works by abusing the SPD (Serial Presence Detect) chip on a memory module, which identifies the module to hardware. It manipulates the SPD into creating aliases for physical memory, which subsequently can be scoured for secrets in contravention of the TEE integrity goals. AMD is tracking the vulnerability under CVE-2024-21944 and AMD-SB-3015. The Ryzen designer confirmed to The Register that it plans to issue an advisory on Tuesday, December 10, 2024.

"AMD believes exploiting the disclosed vulnerability requires an attacker either having physical access to the system, operating system kernel access on a system with unlocked memory modules, or installing a customized, malicious BIOS," the EPYC house explained in a statement. "AMD recommends utilizing memory modules that lock Serial Presence Detect (SPD), as well as following physical system security best practices. AMD has also released firmware updates to customers to mitigate the vulnerability."
