5nm, AM5, PCIe 5.0, DDR5 and many more performance

As expected, AMD took advantage of the opening of Computex to unveil the new range of AMD Ryzen 7000 processors based on the AMD Zen 4 architecture.

Given the appointment, AMD took advantage of the opening of Computex in Taiwan to organize a conference and showcase its new processors. Waiting for the RDNA 3 graphics card, the star of the presentation is the Ryzen 6000s based on the Zen 4 architecture.

These processors are the successors of the excellent Ryzen 5000 which still sees fierce competition with 12th-generation Intel Core processors and, to some extent, Apple’s M1 Max and Ultra chips.

A new platform: AM5

The first major innovation of this generation was the introduction of the AM4 socket, replaced by the new AM5 LGA1718 associated with X670E, X670 or B650 chipsets. Unlike Intel, which changes the socket like a shirt, AMD is more used in longevity and the AM4 socket has been with gamers since the first AMD Zen processors. The good news is that AMD thinks of its users historically. The new AMD Ryzen 7000 processors use IHS (the metal cover that covers the processor) which is compatible with the use of previous generation radiators. In other words, you need to keep your Be Quiet, Noctua, Cooler Master, or other cooler using your new processor.

The new AM5 platform in particular brings support for PCI Express 5.0, which has long been supported by Intel. PCI Express 5.0 SSDs should be legion in the coming months to benefit from double the bandwidth. Support for DD5 RAM is also in the game, but AMD has yet to provide many details. The three chipsets X670E, X670 and B650- will offer support for DDR5 and PCI Express 5.0 storage. It remains to be seen how AMD will differentiate between the different price ranges on these platforms.

With the AM5, AMD promises that we will be entitled to up to 14 USB ports at 20 Gb / s, up to 24 PCI Express 5.0 lines and Wi-Fi 6E with Bluetooth 5.2 LE. As you can understand, it is above all a question of capturing the lead that Intel has taken when it comes to integrating technologies.

AMD Ryzen 7000: the first 5 nm processor for the PC (or almost)

AMD is very proud to announce that the new Ryzen 7000 processors are the first in the desktop PC market to use the TSMC 5nm manufacturing process. With this announcement, AMD forgot to launch Apple’s M1 Ultra chip, which is already used in a desktop PC and still uses the same 5 nm production process. It remains clear that using this process allows AMD to maintain a lead over Intel in this area.

Above all, the Ryzen 7000s introduces a new AMD Zen 4 architecture. The company did not provide all the details, but we already know that there is a mentioned L2 cache of 1 MB per core (double Zen 3). The number of cores will not change with this generation, so we are in front of processors that can accommodate 16. On the other hand, AMD wants to increase the maximum frequency and promises a turbo of more than 5 GHz in all of the same. In an on-stage demo, Lisa Su demonstrated a 16-core Zen 4 processor capable of over 5.5 GHz.

With more cache, frequency, and architectural optimization, AMD promises a +15% increase in performance on a single core. We will have to wait to put the processor in our hands to test this promise.

An integrated graphics chip

This technological choice may shake some processor enthusiasts, betting all their silicon on CPU power. AMD has chosen to integrate a small 6 nm Die into its AMD Zen 4 chips, which will specifically integrate the RDNA 2 iGPU. That is, all processors in the range must offer an integrated graphics chip. What allows simplification of the integration of these processors in the PC, especially in the company. AMD has determined that it is new die at 6 nm should also offer real power savings when the PC is on standby.

Launch this fall

If the presentation didn’t pay attention to a lot of details about the architecture, it’s because AMD allowed time to talk about its chips before launch. In fact, the company has announced that the Ryzen 7000 processors won’t arrive until the end of the year, in the fall of 2022. That’s enough to make a double explosion with the expected launch of the Radeon 7000 graphics card which is also expected by the end of year.
