AMD’s EPYC Genoa-X server processors with 3D V-Cache will arrive later this yr. An alleged engineering pattern (ES) of the EPYC 9684X has gone up on sale for $1,300 on a second-hand Chinese language promoting platform. The Goofish (opens in new tab) vendor claims the processor wields 96 cores and 1,152MB of L3 cache.
Genoa-X, which is able to characteristic TSMC’s 5nm course of node, is the follow-up to AMD’s earlier EPYC Milan-X chips. The upcoming Genoa-X chips will proceed to leverage AMD’s Zen 4 cores, identical to the vanilla Genoa elements, and prime out at 96 cores and 192 threads. Nevertheless, the principle attraction is the implementation of AMD’s 3D V-Cache to spice up Genoa-X’s L3 cache over 1GB.
The pictures for the EPYC 9684X reportedly present that the chip pertains to the EPYC 9004-series lineup. As well as, the “110.10 SP5” marking and the image of the rear of the processor seemingly corroborate that it is at the least an EPYC chip and slots into the Socket SP5 (LGA6096). {Hardware} leaker YuuKi_AnS (opens in new tab) talked about the EPYC 9684X because the flagship Genoa-X SKU so the chip exists. Sadly, the vendor did not share screenshots of the EPYC 9684X.
AMD Genoa-X Specs*
| Processor | Cores | Threads | L3 Cache (MB) | TDP (W) |
|---|---|---|---|---|
| EPYC 9684X | 96 | 192 | 1,152 | 400 |
| EPYC 7773X | 64 | 128 | 768 | 280 |
| EPYC 9384X | 32 | 64 | 1,152 | 320 |
| EPYC 7573X | 32 | 64 | 768 | 280 |
| EPYC 9284X | 24 | 48 | 1,152 | 320 |
| EPYC 7473X | 24 | 48 | 768 | 240 |
| EPYC 9184X | 16 | 32 | 1,152 | 320 |

*Specs are unconfirmed.
Nevertheless, given the product owner’s claims that the EPYC 9684X has 96 Zen 4 cores, it is seemingly the flagship SKU for the Genoa-X lineup. There’s additionally reportedly 1,152MB of L3 cache. It is a substantial enchancment over Milan-X. Milan-X has 768MB of L3 cache; due to this fact, Genoa-X represents a whopping 50% improve. The cache structure additionally consists of 96MB of L2 cache and 3MB of L1 cache. Genoa-X will sport a 1,251MB whole cache per chip if we think about all of the caches.
We already know that the common Genoa has a most L3 cache of 384MB. The 3D V-Cache contributes the remaining 768MB on Genoa-X. It is fairly spectacular what AMD has carried out with Genoa-X. The 3D V-Cache alone on Genoa-X is equal to the whole L3 cache on Milan-X.
With Milan-X, AMD launched 4 SKUs in whole: EPYC 7773X (64 cores), EPYC 7573X (32 cores), EPYC 7473X (243 cores), and EPYC 7373X (16 cores). Assuming that YuuKi_AnS’ insider info is correct, Genoa-X ought to observe the identical mannequin and arrive with comparable core counts with 1,152MB of L3 cache.
Genoa pushed the core rely as much as 96 cores from the 64 cores in Milan. Logically, the TDP can be increased. Genoa has a TDP of as much as 360W, 29% increased than Milan. It is affordable for us to fathom that Genoa-X might land with the next TDP score. In response to the Genoa-X leak, AMD might maintain the flagship EPYC 9684X at 400W and restrain the opposite chips to 320W.
Due to this fact, the EPYC 9684X’s TDP is barely 11% increased than the common 96-core EPYC 9654. In comparison with the earlier EPYC 7773X, although, we’re taking a look at a 43% improve. Moreover, the TDP increments fluctuate between the completely different SKUs. For instance, the EPYC 9384X seems to have a 14% increased TDP than the EPYC 7573X, whereas the EPYC 9284X and EPYC 9184X TDPs are 33% better than the EPYC 7473X and EPYC 7373X.
Genoa already gives AMD’s knowledge middle clients large efficiency because of the beneficiant quantity of Zen 4 cores. Genoa-X will undoubtedly construct upon that and supply additional firepower for latency-sensitive workloads. Genoa-X will launch in 2023, though AMD hasn’t specified when.
