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.
