AMD Epyc Genoa sequence leaks: introducing 96-core and 84-core CPUs

Posted on

In context: Past due closing 12 months, AMD introduced the fourth-gen Epyc sequence, codenamed Genoa. It is now escaped from AMD’s labs and is passing during the arms of leakers prior to it may possibly make its approach onto the open marketplace within the coming months.

In line with AMD CEO Lisa Su’s keynote closing 12 months, Genoa processors must have as much as 96 cores in accordance with the Zen 4 structure and use the TSMC 5nm node. They are meant to have two times the density and tool potency in their previous sequence, Milan, and 25% extra functionality general.

Yuuki Ans, a prolific leaker within the high-performance compute sector, has revealed a spreadsheet containing probably the most specifications of eighteen fashions. His leaks appear to come back from AMD’s companions and are generally just right, however the finer main points, like clock speeds and TDPs, are not ultimate but and may trade.

Some processors are simplest known as engineering samples, abbreviated as ES within the tables under. In circumstances the place P and non-P fashions have similar specifications, the 2 variations are condensed into one row.

8-12 chiplets

Fashion Cores / Threads Base Clock Pace TDP L3 Cache
Epyc 9654P 96 / 192 2.00 – 2.15 GHz 360W 384 MB
ES 96 / 192 2.00 – 2.15 GHz 320 – 400W 384 MB
ES 84 / 168 2.00 GHz 290W 384 MB
Epyc 9534 64 / 128 2.30 – 2.40 GHz 280W 256 MB
ES 64 / 128 2.50 – 2.65 GHz 320 – 400W 256 MB

As you would be expecting, upper core counts are met with upper TDPs and decrease base clocks. On this bracket, Genoa has an identical base clocks to Milan however upper TDPs, even for the 64-core fashions.

4-6 chiplets

Fashion Cores / Threads Base Clock Pace TDP L3 Cache
Epyc 9454(P) 48 / 96 2.25 – 2.35 GHz 290W 256 MB
ES 48 / 96 3.20 – 3.40 GHz 360W 256 MB
Epyc 9354(P) 32 / 64 2.75 – 2.85 GHz 280W 256 MB
ES 32 / 64 3.20 – 3.40 GHz 320W 256 MB
ES 32 / 64 2.70 – 2.85 GHz 260W 256 MB
Epyc 9334 32 / 64 2.30 – 2.50 GHz 210W 128 MB

Genoa’s mid-tier fashions are clocked a long way above Milan’s, however additionally they have upper TDPs. While Milan’s 48-core and 32-core fashions have been capped at 280W, Genoa’s blast previous that and exceed 300W.

2-3 chiplets

Fashion Cores / Threads Base Clock Pace TDP L3 Cache
Epyc 9274F 24 / 48 3.40 – 3.60 GHz 320W 256 MB
Epyc 9254 24 / 48 2.40 – 2.50 GHz 200W 128 MB
Epyc 9224 24 / 48 2.15 – 2.25 GHz 200W 64 MB
Epyc 9174F 16 / 32 3.60 – 3.80 GHz 320W 256 MB
Epyc 9124 16 / 32 2.60 – 2.70 GHz 200W 64 MB

Genoa gifts some just right choices at this stage, like 24-core and 16-core fashions supplied with 256 MB cache and base clocks attaining 3.5 GHz. On the other hand, they proceed the fad of eating extra energy than their predecessors. For comparability, Milan’s 64-core fashions had TDPs under 300W, however Genoa’s 16-core fashions achieve the 320W threshold.

To energy them, Genoa has a brand new socket known as SP5. It could possibly deal with as much as 700W and also will enhance Genoa’s counterpart for the cloud, Bergamo. Moreover, it helps new options, together with 12-channel DDR5 and PCIe 5.0.

Genoa is scheduled for this 12 months and may arrive quickly. Bergamo must arrive within the first part of subsequent 12 months.
