AMD has used the Computex 2022 framework to present its new generations of chips. processors stand out Ryzen 7000 for desktops and the platform that will support them, the AM5 socket and the three different chipsets that the company will launch to cover the entire product range.
AMD offered last January at CES the first preview of ZEN 4, the new architecture that has come to define the future of its processors in the medium term since it is the basis for the Ryzen 7000 consumer processors that we are going to see in this post. , as well as Threadrippers for workstations and next-generation EPYCs for servers and data centers to be announced in the coming months.
AMD Ryzen 7000
Like all the great announcements of AMD, the presentation has been carried out by its CEO, Lisa Su, in a keynote that incidentally has served as a starting signal for the great fair in Taiwan that officially begins tomorrow and will last until Thursday.
As we said, the Ryzen 7000 have been created on the basis of the ZEN 4 architecture and they release the new 5nm manufacturing process from the TSMC foundry. Like the Ryzen 5000, they use the MCM (multi-chip module) core design, but will double the number of cores per chiplet, going from 8 to 16 cores. The die for the I/O die also uses a new 6nm process, a significant improvement over the previous generation die that was manufactured in 12nm.
The jump to 5nm for the CCD will allow AMD to scale up to 16 Zen 4 cores per chiplet, all of which are “high-performance” cores, as the executive has pointed out. It is a reference to Intel’s hybrid design with Alder Lake and its “efficient” cores, the direct competition of these Ryzen 7000.
The CPU core is also larger to include, among other new features, a 1 Mbyte per core L2 cache, the double of the 512 KB present in all previous “Zen” versions. It is necessary to point out another novelty that until now AMD reserved for its designs of accelerated processing units (APUs), and it is the inclusion of an integrated graph with RDNA2 graphics architecture, surely in response to the improvement of the Intel graphics section with the Xe Gen12 iGPUs of the Alder Lake-S.
As for its capacity and as we already told you, the Ryzen 7000 is expected to offer a single-wire performance increase of up to 37% and an IPC improvement of 15% compared to the Ryzen 5000. It may not be as spectacular in multithreading, but a level jump is also expected in this section. Part of this will be the responsibility of the increase in working frequencies. And not a little, since it has been talked about 5.5GHz in turbo mode, the highest value of any previous AMD CPU. In the image, the CEO of AMD “showing off” the performance against the Core i9-12900K:
A hypothetical Ryzen 9 7950X with two Zen 4 chiplets could offer 32 cores and 64 threads, plus 128MB of 3D-stacked L3 cache. A ‘bestial’ CPU also in consumption since its TDP would be around 170 watts. We will already offer you a technical article with all the details of these Ryzen 7000, but everything announced so far sounds highly promising for AMD and a competition with Intel that will benefit the industry and consumers.
AM5 socket and 600 series chipsets
Another great novelty of the platform is the new socket known as AM5 (LGA1718)which together with three different chipsets, will allow AMD to catch up on the latest technologies such as PCIe 5.0, the DDR5 memory standard and the most advanced connectivity interfaces such as Wi-Fi 6E or USB4.
Confirm what we already knew about this new socket and that is that it changes the current CPU connection system based on pins (PGA) to one based on contact arrays (LGA). Holds up to 24 PCI-Express 5.0 lanes from the CPU16 of them for PCI-Express slots (used for dedicated graphics cards) and another 4 lanes connected to an M.2 NVMe module.
It must be said that Intel’s Alder Lakes also feature 16 Gen 5 lanes towards the PCIe slots, but the connection between the CPU and M.2 occurs under Gen4. Hence, AMD has highlighted that the Ryzen 7000 will be the first with M.2 slots based on PCIe Gen 5. AMD is working with Phison to optimize the first round of Gen 5 solid-state drives for the platform, though older generation solid-state drives may also work.
The Ryzen 7000 only support DDR5 memory two channels (four subchannels). Identical to the “Alder Lake”, although unlike Intel they do not support DDR4, which will mean that the user who wants to make the leap to this platform will have to buy new DDR5 memory modules and a latest generation motherboard. We can’t fault AMD for lack of backwards compatibility as they’ve kept it up for several generations, but there’s no question that they want to start with a completely new platform here.
The platform will also offer up to 14 20Gbps USB ports, and once it’s decided that integrated graphics should be integrated, motherboards will feature up to four DisplayPort 2 or HDMI 2.1 ports. The company will also standardize solutions Wi-Fi 6E + Bluetooth WLAN which it has co-developed with MediaTek to move away from designs that use Intel WLAN solutions.
Three different chipsets
AMD’s AM5 platform will come in three different chipset options: AMD X670 Extreme (X670E), AMD X670 and AMD B650.
The X670 Extreme will be the most advanced, offering the most performance and connectivity, running entirely on PCIe 5.0 across all 24 lanes. The X570 would offer 20 PCIe Gen 4 lanes from the CPU output, while retaining CPU-attached NVMe connectivity and PCIe Gen 5 slots. The B650 will be the cheapest and mix various interfaces.
AMD has announced the most advanced motherboards coming for the platform and we see from all the major manufacturers such as ASUS ROG Crosshair X670E Extreme, ASRock X670E Taichi, MSI MEG X670E ACE, GIGABYTE X670E AORUS Xtreme and BIOSTAR X670E Valkyrie which we will see with more detail in future articles. Also innovations that will improve the platform in general, such as support for Microsoft DirectStorage with the new AMD Smart Access Storage technology.
Ryzen 7000 processors and AM5 motherboards expected to be available the next fallwe assume October as the key month for the launch.
