In the afternoon Financial Analysts Day 2022 event, AMD shared its plans to create EPYC servers. The event was about previously released products as well as brand new ones for segments that weren’t popular with AMD in the past.
The most important, and the most comprehensive announcement was made in the Fifth Generation of AMD EPYC, called Turin (EPYC 7005) that will be available prior to 2024. The new generation will be built on a completely revamped Zen 5, and made with the mix processes of 3- and 4-nm technology. Three kinds of crystals are expected to be offered three types: regular, 3D-Cache and cloud. They will also an increase in the number of places they can be placed. It is also necessary to keep the continuity between generations, which is bound to satisfy customers.

In the near term, we’re awaiting the launch of AMD EPYC Genoa that will occur within the final quarter of the year. The 5nm processors come with an aforementioned 96 Zen 4 cores and 12 DDR5 channels and PCIe 5.0 and CXL support. This means that it is now explicitly stated that there’s a possibility of increasing the memory in computers by using CXL. It was a change in technology and the expansion of numbers of processors, with an increase of 1 -fold brought the performance reach 75 percentage (an illustration is a Java test called Specjbb).
In order to run Genoa the new socket is required (LGA 6096). It will be able to take two other processors also. First, there’s the Genoa-X, of which it’s very easy to identify it is the identical Genoa (altogether that has up at 96 cores) which is equipped with L3 cache with dual cores, that can be priced at $1.3 for 1 GB. As with Milan X the Genoa-X will focus on a specific group of tasks that can benefit from the availability of more caches. For instance, they are calculations and DBMS.
Genoa-X will be on show in 2023. It will then be great to see a special show Bergamo. The processors can be upgraded to 128 cores and 256 threads as originally promised by the developer, while remaining compatible with SP5 socket. The processors are based on Zen 4c Zen 5nm cores that resemble Intel’s E-cores. However, the command that is set to be utilized for Zen 4 will be the same as that for Zen 4. Also, AMD did not reveal details about the c-core device, but can it be believed that they’ve revamped to improve the hierarchy of caches? They’re designed for hyperscalers who are concerned about resource density , and not just performance.
The year 2023 will see a tiny group of yaos from the group will be released with the title Siena. They’re designed for energy efficiency and have 64 Zen 4 cores. Siena’s attention is on the top of the line technology and the telecom industry. They’re barely under the scrutiny. There’s a chance of hybrids such as Ice Lake D, and smart network controllers.
As for the new products, Zen 4 (4 and 5 nm ) will be the main ones along with new features to be offered to customers. These include support for AVX-512 (perhaps it’s not the complete set) and brand new directions to perform AI jobs which Intel has been demonstrating for a number of years. Now, however 4th generation Infinity Architecture interconnect will be accessible in the infinity Architecture that allows switching to chiplets that are larger as well as the levels of silicon (2.5D and 3-D Packaging).
It also opens the way to seamless packaging of various functional modules, and allows for coherence on the level of chips. It also supported an integration with FPGA Xilinx as well as third-party IP blocks. This new interface is fully compatible to CXL 2.0. This is essential to work with memory and the later versions will work by CXL 3.0 and UCIE. The fourth-generation of Infinity which allowed AMD to build its very first MI300 Server APUs.
