AMD yesterday expanded the Epyc 9004 family of server processors by six new models. These are the expected chips that boost performance in two ways. Some add a 3D cache layer to processor chiplets with standard Zen 4 cores, others use more smaller Zen 4c cores.
Processors Genoa-X formed by the 9184X, 9384X and 9684X models have 16, 32 and 96 cores, work in twice as many threads and, thanks to the added buffer layer, have 1152 MB of L3 cache, respectively 768 MB for the two lower models. The clocks are slightly lower than the original models, but the larger cache can result in higher performance for applications sensitive to memory throughput.
AMD says the 9684X’s performance is 2.2x to 2.9x higher than the 60-core Xeon 8490H, Intel’s current flagship. These are much more expensive (17 instead of 15 thousand dollars), but they can be installed in up to eight-processor systems. AMD supports a maximum of two sockets.
Chips also work with lower clock rates Bergamo, namely the Epyc 9754S, 9754 and 9734 models. These have modified Zen 4c cores, which sacrificed part of the silicon designed to support higher frequencies in order to fit more of them on the same surface. While one Zen 4 core including the L2 cache produced by the 5nm process at TSMC takes up 3.84 mm², Zen 4 only needs 2.48 mm².
The SP5 socket and the supported instructions are the same, the chips are fully interchangeable. But Bergamo will head to such servers where it makes sense to have as many cores as possible. Genoa(-X) offered a maximum of 96, Bergamo has 112 or 128. AMD claims that the Epyc 9754 is 3.7x more powerful and 2.7x more efficient (power per watt) compared to two 128-core Ampere Altra Max with arm cores .

In addition to server processors, AMD also introduced a new computing card Instinct MI300X. Compared to the recent MI300A (rechristened from MI300), it no longer contains chiplets with processor cores, but only an enlarged GPU of the CDNA 3 architecture. The company is silent on performance for now, the first customers will receive accelerator samples only in the second half of the year. The advantage is supposed to be more memory, 192 GB of HBM3 with a tremendous throughput of 5.2 TB/s fit on the card.
