AMD is about to raise the bar on processors. The company is preparing the first processor based on 128 cores with x86 architecture. We are talking about the Bergamo server processors – they will have up to 128 simplified Zen4c cores, and the L3 cache will reach 256 MB.

AMD positions the Bergamo family of server processors as an offshoot of the core Zen 4 architecture, designed for the largest possible number of cores. According to the company’s promises, these processors should see the light of day in the first half of 2023.

To stick to the schedule, AMD will introduce Bergamo this month, German source ComputerBase claims. Bergamo is expected to debut at the Data Center & AI Technology Premiere event scheduled for June 13.

Many factors speak to Bergamo’s impending announcement. For example, user @momomo_us, who has access to inside information, showed a screenshot with the specification of two versions of Bergamo.

One of the chips is the flagship AMD EPYC 9754 with 128 cores and 256 threads. Its clock speed ranges from 2.25 GHz (base) to 3.10 GHz (turbo). The L3 cache has a volume of 256MB and a TDP of 360W.

Another model, the AMD EPYC 9734, has 112 cores and 224 threads. However, the L3 cache memory is the same size – 256 MB. The clock frequency is close to the frequency of the EPYC 9754 – from 2.2 to 3.0 GHz. At the same time, the TDP of EPYC 9734 is slightly lower – 340 watts.

Meanwhile, another user @SprayOnCopper posted a screenshot of EPYC 9754 with 128 cores found in Windows Task Manager. The chip has a base clock speed of 2.25 GHz. The fact that Windows detected 512 MB of L3 cache, according to the user, suggests that this is a dual-processor system.

It remains to be seen if AMD will present at the same event a Zen 4-core Genoa fork called Genoa-X, which is equipped with an additional 3D L3 cache – these processors are expected in 2023.

To date, EPYC processors have a maximum of 96 Zen 4 cores and 384MB of L3 cache. With the advent of Genoa-X, the maximum cache size of AMD server processors will reach 1152 MB. But for cases where more cores are more important than cache size, AMD is developing Bergamo.
