AMD's upcoming Zen 4 "Genoa" processors will deliver the company's enterprise customers some major upgrades. For starters, AMD's new EPYC processors will deliver users up to 96 cores and 192 threads, representing a major uplift over today's Zen 3 Milan series processors. Beyond that, these new CPU cores will utilise AMD's new Zen 4 core architecture, delivering users more per-core performance. Add on PCIe 5.0 and DDR5 memory support, and AMD's onto a winner with Genoa. 

An image of an AMD Genoa series processor has been uncovered by @phatal187 on Twitter, an image that comes from TF AMD in Malaysia. This image has been online for approximately 10 months, quietly flying under the radar or most leakers and analysts. With twelve CPU chiplets and a single I/O chiplet, the image below confirms that AMD's Genoa processors will feature up to eight CPU cores per CPU chiplet, making Genoa similar to Milan in that regard. These same CPU chiplets are expected to be used with future Zen 4 Ryzen processors. 

AMD's Genoa series CPUs will utilise AMD's new SP5 CPU socket, a socket that is larger than today's SP3 socket from AMD. AMD's Zen 4 CPU chiplets appear to be slightly smaller than AMD's Zen 3 chiplets, thanks to AMD's use of TSMC's 5nm lithography technology. That said, the increase silicon density of 5nm will allow AMD to pack more transistors into this smaller area. AMD's I/O die for Genoa also appears to be smaller than the 14nm die used for ROME/MILAN (Zen 2/Zen 3) EPYC processors.

AMD's Zen 4 SP5 socket reportedly supports 12-channel DDR5 memory and PCIe 5.0 connectivity. These factors alone will give GENOA a major boost in connectivity and memory bandwidth over todays Zen 3 Milan series EPYC processors from AMD. Beyond that, AMD's Zen 4 EPYC processors will support the CXL standard.

AMD is on track to release its Zen 4 EPYC processors later this year, giving their customers access to more CPU cores, faster memory and I/O connectivity, and more performant Zen 4 CPU cores.
