On March 25th, AMD is gearing up to launch its lineup of processors based on the Zen5 architecture, spanning across desktop, laptop, and data center segments. Now, we've caught a glimpse of a preliminary model and specification list for the Zen5 Turin EPYC 9005 series processors, and it's truly groundbreaking.
The EPYC 9005 series currently comprises up to 20 models, with core counts ranging from 8 to 160 cores. It's rumored that the Zen5 architecture supports up to 128 cores, while the Zen5c architecture can handle up to 192 cores.
For instance, the EPYC 9845 boasts 160 cores with a whopping 640MB of L3 cache. However, its base clock is relatively low at 2.0GHz, and it has a hefty thermal design power (TDP) of 500W.
Comparatively, the EPYC 9654, with 96 cores, has a base clock reduced by 400MHz and a TDP increased by 140W.
On the other hand, the upgraded version, EPYC 9655, also with 96 cores, sees a base clock increase of 300MHz to reach 2.7GHz, with a 40W higher TDP.
The EPYC 9175F and 9275F stand out with the highest base clocks of 4.0GHz, featuring 16 and 24 cores, respectively. However, they also come with a substantial TDP of 320W.
Another set of system specifications indicates that the EPYC 9005 series continues with the SP5 socket interface, ensuring platform compatibility. DDR5 memory channels have been reduced from 12 to 8, with the maximum capacity per channel decreasing from 6TB to 4TB, but the frequency has significantly increased from 4800MHz to 6000MHz. PCIe 5.0 lanes have slightly decreased from 128 to 120, which can be divided for different purposes, including four MCIO x16, one CXL x16, one OCP/CXL x16, one GenZ/CXL x16, and two M.2 x4. The Zen5 EPYC 9005 series is set to be released in 2025, which is still quite some time away. The current disclosures represent preliminary information, and it's possible that there may be changes, particularly in terms of model specifications, in the future.
