AMD releases EPYC 9004 server processors with 96 Zen 4 cores, PCIe 5.0 and DDR5 – Computer – News

AMD broadcasts the supply of its fourth technology EPYC server CPUs. These CPUs have as much as 96 cores based mostly on the Zen 4 structure and assist PCIe 5.0 and DDR5. Later, ‘Zen 4c’ processors with as much as 128 cores and 3D V-Cache variants will observe.

Of AMD EPYC 9004-processors are based mostly on the Zen 4 structure, which AMD beforehand launched in its Ryzen 7000 desktop CPUs. With this, the processors are produced on TSMC’s 5nm course of, the place the earlier EPYC Milan CPUs have been made at 7nm. In keeping with AMD, the brand new structure represents a 14 % IPC enchancment, together with from an improved frontend, load/retailer and department prediction.

The brand new EPYC CPUs encompass a number of Zen 4 chiplets, which, as with earlier generations, every include eight cores. Nevertheless, AMD is rising the utmost variety of chiplets per EPYC 9004 processors to 12. Which means the highest mannequin has a complete of 96 cores, whereas earlier EPYC processors had a most of 64 cores. AMD can also be introducing variants with 84, 64, 48, 32, 24 and 16 cores. In complete, the corporate comes with eighteen totally different fashions, together with larger clocked F fashions.

As with the earlier technology of EPYC processors, AMD positions the processors in three classes: Core Efficiency, Core Density and Balanced & Optimized. The previous class contains F fashions, which have comparatively excessive clock speeds. The fashions with 96, 64 and 48 cores fall below the Core Density class and different variants with 16 to 32 cores fall into the third class. This ‘balanced’ class is aimed toward a steadiness between efficiency and prices.

EPYC 9004 CPUs get 128 PCIe 5.0 lanes and 12 DDR5 channels, with assist for as much as 6TB DDR5 reminiscence per socket. Every Zen 4-core additionally has 1MB L2 cache and every chiplet will get 32MB L3 cache, for a most of 384MB within the case of 96-core CPUs. The CPUs will obtain CXL 1.1 assist for reminiscence growth.

Genoa is obtainable by cloud suppliers corresponding to Microsoft and Oracle and producers corresponding to Dell, HPE, Lenovo and Supermicro. It’s the first collection of EPYC processors based mostly on the Zen 4 structure to be launched by AMD. EPYC ‘Bergamo’ processors may even observe later. They’re optimized for cloud purposes and have a Zen 4c structure. AMD beforehand confirmed that these processors have a most of 128 Zen 4c cores. Genoa-X CPUs are additionally on the roadmap. These concern EPYC 9004 processors with 3D V-Cache, as AMD beforehand launched in its earlier technology of server processors. A Sienna collection of Zen 4 CPUs for telecom and edge purposes are additionally deliberate.
