This year, AMD will introduce the new Zen 4 processor architecture, which it will use in notebooks, desktops in the form of Ryzens, workstation Threadrippers and Epyc server chips. And it is these that push the limit of how many x86 cores can be stored in one case. The existing Epycy Milan had 64 cores, the Epyc Genoa will have up to 96 cores capable of processing 192 threads.
Last year, the company itself also confirmed other previously speculated information. Genoa will use 5nm production, include a 12-channel DDR5 controller and will support PCI Express 5.0. After the weekend, we already have the first picture of what the chip should look like (see gallery).
It shows a large central I / O chiplet and twelve processor chipsets in four groups of three, each chiplet will contain eight cores, as in the current generation Zen 3. The photo may only show a mock-up, not a functional unit. But its source should be reliable. The image was shared by TF AMD Microelectronics, which deals with chip encapsulation. It is, after all, a former division of AMD itself, but the factories were sold and retained only a 15% stake in them.
Videocardz magazine also showed two pictures of the allegedly already finished chip, on which we see 6096 contact pads and a heatspreader. The first photo showing the new SP5 slot (LGA 6096) together with twelve memory banks then appeared on the STH forum.
