Finally, after several months of rumors, AMD has presented its Ryzen 7000 with Zen 4 architecture . The first of its family of processors compatible with its new AM5 socket and which represents the most important leap for Intel‘s rival since the launch of its Zen 2. All this thanks to the adoption of technologies such as DDR5 and PCI Express 5.0. For the moment we will focus on the news of this next generation CPU that Lisa Su has shown at Computex.
The launch of the Ryzen 7000 for desktop is expected in the fall of this 2022, so we are talking about the months of October, November or December for its official launch. At the moment, from AMD they have not given information about which models we will see and what their specifications will be . Of course, they have left us an advance to put on our long teeth. Apart from the fact that they have clarified a series of rumors that have come out of the gossip in recent days. Given that the amount of information is enormous and it is convenient to synthesize it to understand what this new processor or CPU will mean for our PCs, we have decided to order it and present it to avoid confusion for our readers.
This is Ryzen 7000, the new processor for PC PC
Under the name of Ryzen 7000 we have the third desktop processor designed by AMD and manufactured by TSMC of a disaggregated nature. That is, composed of chiplets. Again we are facing the same configuration as the Ryzen 5000 and Ryzen 3000. That is, on the one hand, the CCD Chiplets that contain the processing cores and their cache memory. On the other hand, the IOD that brings inside the integrated memory controller and access to the system’s RAM memory.
New CCD based on Zen 4
The new CCD is built under TSMC’s 5nm or N5 node . It can be made up of up to 8 Zen 4 cores , which bring a 15% increase in IPC performance compared to Zen 3. Together they can reach speeds of more than 5 GHz and up to 5.5 GHz in the case of overclocking. 1 or 2 cores. Its L2 cache memory has been increased from 512 KB to 1 MB in Zen 4 and improvements have now been added for the AI. This is the adoption of AVX-512 instructions for the first time in an AMD CPU .
New IOD for DDR5 and PCI Express 5.0
As for the IOD, it is an important change, due to the fact that since the Ryzen 3000 that AMD continued to use it. AMD leaves Global Foundries to adopt a new chip manufactured under TSMC’s 6nm node . The changes have been forced by the appearance of new standards such as DDR5 memory and PCI Express 5.0 . Although the most important change is that for the first time AMD has integrated a GPU in the IOD , which also means the inclusion of video codecs .
At the moment we do not know the specifications of the chipset of the motherboards that will accompany the Ryzen 7000, but what we do know are the interfaces that have been included within the processor and which ones belong to the chipset.
- 24 PCI Express 5.0 lanes , divided as follows: 16 for the graphics card, 4 for the M.2 SSD , and 4 for the motherboard chipset .
- Up to 14 USB 3.2 interfaces up to 20 Gbps . So this may be limited by motherboard.
- The support for wireless networks refers to the fact that the WiFi radio will be wired to the IOD.
- Up to 4 HDMI or DisplayPort ports for integrated graphics within the IOD.
At the moment, this is all that AMD has presented for the Ryzen 7000 at Computex. However, one last element is still missing.
Motherboards for AMD Ryzen 7000
Apart from the presentation of the new processor, we have also been able to learn about the different chipsets that will be seen in the market during the launch and that will define the different motherboards. For the time being AMD will focus on the enthusiast market with the X670 Extreme, X670 and B650. All of them arranged in descending order in benefits.
In all of them, AMD is committed to the adoption of NVMe SSDs with PCI Express 5.0 interface . For this, it has made a close collaboration with Phison, so we should start seeing these types of units on the market after the Ryzen 7000 are launched. Are you ready for storage units with speeds of up to 14 GB/s of bandwidth?
Apart from this and the support for overclocking in the X670, for now we will have to wait for the launch so that AMD gives us the missing details about the different chipsets and how they differ.
