At CES 2022, the next-gen Ryzen with Zen 4 architecture as well as socket AM5 was demonstrated for the first time. Samples of these 5nm chips according to AMD in games already handle the 5 GHz clock on all cores.
AMD on Tuesday announced the release of the Ryzen 7 5800X3D processor with 3D V-Cache technology, which is to be released sometime in the spring, but also talked about its successor, desktop processors with Zen 4 architecture. And a demo was shown, according to which Zen 4 will reach 5 GHz on all cores, which is good news about 5nm technology.
They leaked to the internet last year first information about the new AMD desktop platform, an AM5 socket that will bring in DDR5 memory and come with Zen 4 and 5 architecture processors. unofficial 3D visualization what the CPU itself should look like. On Tuesday at CES 2022, these rumors were fully confirmed, as AMD has already physically shown the Ryzen 7000 processor for the AM5 socket. And next to it, there is also the AM5 socket, which for the first time on AMD mainstream processors has an LGA design with pins on the board (which prevents CPU damage, but again it is a more expensive and prone board).

The AM5 socket processors are roughly square with two cutouts on the sides, the position of which is to prevent the installation from being in the wrong orientation. The underside, unlike Intel’s solution, is completely covered with contacts and does not contain any SMD components. They are therefore on the upper side of the substrate, atypically along its edges. Due to them, the metal heat spreader does not have a continuous edge, but sits on the processor substrate with nine legs, between which there are gaps for seating components. So the processors for socket AM5 will be very characteristic and you will recognize them at first sight.
Zen 4 will be released “in the second half of the year”
Ryzeny 7000, whose samples are in the photos (whether fully functional or just dummies, we do not know), will have a Zen 4 CPU architecture and are manufactured on a 5nm process. They have the code name “Raphael”, which by the way they should also have basic integrated GPUs, although AMD has not yet officially confirmed this. The silicon of the CPU chiplets is 5nm for the first time.
And AMD also announced for the first time when roughly these processors will be released. So far, however, it is only defined that they will start selling in the second half of the year. So we know more or less that they are planned for this year and it may be the end of the year.

In any case, this precludes them being released before July, but this was probably never a probable possibility. AMD boss Lisa Su also confirmed that the AM5 platform itself will be released in the second half of the year. It will not happen that AM5 boards will be released, for example, in May or June, so far only for the desktop 6nm APU Ryzeny 6000 “Rembrandt”.

AM5 will support PCI Express 5.0
In addition to the AMD processor, it also showed the AM5 socket in its presentation, so you can see the metal fastening mechanism in the photo. Slides have confirmed that it contains 1718 pins and that it will use DDR5 memory as expected. There is no mention of DDR4, it is likely that the socket will be exclusively associated with the new type of memory, just like AM4 with DDR4. It will be possible to use a cooler from the previous platform, those for AM4 will reportedly be compatible with AM5.

But what’s in it: AM5 is said to support PCI Express 5.0. That’s good news, because previous leaks said there would still be only PCI Express 4.0 on the platform. But now AMD also officially promises PCIe 5.0, so concerns can be postponed. However, it is probably possible that the Ryzena 7000 Raphael could only support PCIe 4.0. while PCIe 5.0 would bring up the next CPU. AMD directly on the Ryzen 7000 did not mention or rule out PCIe 5.0 support.
All-core boost 5 GHz na Zenu 4
AMD at CES 2022 has not yet shown the Ryzen 7000 running live (nor the server version of Zen 4). However, one demo was shown, but only on the recorded video. This may or may not indicate how debugged and reliable the samples of these CPUs are now.
The video recorded on the video showed the game Halo Infinite on a pre-production sample of 5nm Ryzen (ie generation 7000 / Zen 4). The game ran in 1920 × 1080 resolution, reportedly with high FPS, but what exactly this means was not specified. There is no pointer anywhere in the video.

The important information, however, is that according to the presentation in this game, the processor ran with all cores at a frequency of 5.0 GHz. This is something you will not achieve today with the Ryzen 5000. Only the Ryzen 5950X reaches 5.0 GHz on preferred cores at single-fiber loads. So it seems that Zen 4 will bring a general increase in beats, although it will have an advanced 5nm process, for which there were some concerns that it could reduce frequencies (given that it was originally tuned mainly for mobile use). But it looks like it will achieve both energy efficiency for multithreaded loads and GPUs, and high maximum boost performance.
How many cores the Zen 4 sample had when we talked about the boost “on all cores”, but that was not said. The most probable is that it was a single-chip sample, ie with a maximum of eight Zen 4 cores.
This demo looks like a response to the presentation of the upcoming Core i9-12900KS, which in turn will probably offer 5.2 GHz on all eight P-Core cores (but even 5.5 GHz on one preferred in single-threaded loads).

However, as already mentioned, AMD may not have this answer until the end of the year, unless there is some surprise that the Ryzena 7000 will start selling in August or September, for example, which we rather do not expect.
