AMD announces fourth-generation EPYC processors: No competition

Although it is ambitious on the end-user side, the best place for AMD is of course servers. Especially Zen-based EPYC processors have taken a significant share from Intel and succeed in surpassing its rivals with each new generation. Zen 4 server processors, codenamed AMD EPYC Genoa, will again make a difference.

AMD EPYC 9004 Genoa processors

AMD EPYC 9004 Genoa processors will be the first product of a new strategy and will expand its usage area by appealing to different segments. Prices will vary according to core and cache sizes.

Genoa processors produced in the 5nm process are based on the chiplet design. These designs, which have up to 12 pieces in total, offer the number of cores according to the piece condition. Compared to end-user Zen 4 products, it offers an increase of 14 percent in IPC and around 1 percent in performance. Although the membrane areas are lower, the package area and socket area have increased. This causes it to rise to 700W.

Offering up to 12 channels of 4800Mbps DIMM memory support, the processors have features such as 160 PCIe Gen 5 lines, 12 PCIe Gen 3 lines, 32 SATA lines, and 64 input lines with CXL support.

There are 4 processors with 12 parts in the new series. These models, which go up to 96 cores and 192 thread units, include one product with 84 cores and 168 thread units. Level 3 cache is 384MB, while consumption is between 290W-400W.

Out of 8 processors with 8 parts, 3 of them are 64-core, 2 of them are 48-core and 2 of them are 32-core. Besides 256MB Level 3 cache memory, there are 280W-360W consumption values. 4-part processors are ranked as 16 cores, 24 cores, and 32 cores. The starting price is $1083 while the peak price is $11805. Apart from these, there are 4 8-piece processors and some of them are above 4GHz. Prices vary between $3060-$6780.

While EPYC Genoa processors lead the way in many benchmark tests, it is stated that 320 thousand AMD 9654 servers can meet 1 million Intel 8380 processors. Thus, carbon emissions are also significantly reduced.

Genoa processors began to be supplied to customers. In addition, EPYC Bergamo processors based on performance-oriented Zen 4C cores, EPYC Siena based on cost-oriented Zen 4 cores and EPYC Genoa-X processors with 3D V-Cache will be introduced in the next year.
