AMD Ryzen 7000: new generation CPUs in late 2022

AMD has started revealing key specs for the Ryzen 7000, its upcoming desktop processors. On the agenda are Zen 4 architecture, 5nm engraving, PCIe 5.0 and DDR5 for high performance.

AMD has clearly returned to the top of the computing scene in recent years. And wants to stay that way! Thus, after a long lull in which it lagged far behind Intel with unattractive processors, the American company has been able to bounce back and even take the lead in the technological race with its famous Ryzen CPUs, with a particularly advantageous quality-price ratio, having achieved enviable results enjoyed, to standards for gamers who have always loved processing power. And when Intel, beaten in its pride, was able to close the gap to its eternal competitor with its Core 12 familyand Generation, known as Alder Lake (see our article), some representatives of which claim the best places in the benchmarks, AMD wants to regain the lead with its new Ryzen 7000 series, which is scheduled for release in autumn 2022.

So while rumors and leaks had been circulating for months, AMD used the opening of the Computex 2022 trade fair in Taiwan to officially present its future processors for fixed PCs. Next-gen CPUs and decidedly high-end that will benefit from several improvements over the current models of the already powerful Ryzen 5000 series. But also in comparison to the chips of the latest Ryzen 6000 Mobile family, which are intended for laptops.

Ryzen 7000: new generation CPUs with Zen 4 architecture

On the technical side, the Ryzen 7000 processors – which, like everyone else, will be available in several versions – will inaugurate a new architecture, Zen 4, which will follow the current one, Zen 3, by bringing several improvements at the level of the internal organization. The Ryzen 7000s, which can have up to 16 physical cores and 32 logical cores (for parallel processing, threads), will be built on a pretty clever hybrid structure that will have two identical chiplets engraved in 5nm technology and an input module – outputs ( I/O) is made in 6nm technology and takes advantage of the new techniques developed by TSMC, the great specialist in electronic circuits that, among many others, also produces Apple’s M1 chips. By moving from the 7nm engraving used for the Zen 3 architecture of the best current Ryzen 5000 to a fineness of 5nm, AMD should be able to integrate more transistors into its processing units and at the same time the optimize power consumption. An advantage over Intel, which still relies on 10 nm technology for its Core 12and Generation – which doesn’t stop them from offering excellent performance – but not compared to Apple, which has already moved to 5nm in its M1 chips.

In practice, the Zen 4 architecture makes it possible to increase each core’s level 1 cache, which ranges from 512 KB to 1 MB on a Ryzen 7000. It may not seem like much, but this ultra-fast memory resides within the chip itself, allowing processing to be significantly speeded up. In addition, AMD promises, without giving details, that the Ryzen 7000 will exceed 5 GHz during intensive calculations in turbo mode. During her demo presentation on stage, AMD CEO Lisa Su demonstrated a 16-core Zen 4 model clocked at 5.5 GHz. An impressive frequency that should allow these new CPUs to offer very high performance. What these improvements will bring in reality is difficult to assess, however, as AMD has been relatively vague on this point, limiting itself to generating a relatively modest 15% gain for single-core operation. (single thread), but without specifying the reference model or the measurement conditions. It is to be hoped that the Ryzen 7000 will mark more differences in reality, even when operating with multiple cores (multiple threads) to be able to justify their next-gen high-end status and take precedence over the latest Intel chips…

Ryzen 7000: DDR 5 and PCIe 5.0 for high performance

Of course, the Ryzen 7000 bring many more innovations compared to the 5000 generation, to the point that AMD had to change the type of support (sockets) that will accommodate them on motherboards. Thus, the AM4 format introduced in 2017 and used on the current Ryzen will give way to the AM5. Main consequence: the obligation to install the Ryzen 7000 on new motherboards without the possibility of restoring the current ones. As a consolation, AMD has ensured that the Ryzen 7000s metal cover (the IHS) remains compatible with cooling devices designed for socket AM4. In the absence of savings – you still have to buy a processor, motherboard and RAM… – you have a choice once these CPUs arrive. Be careful, however, as the maximum TDP (the thermal envelope) ranges from 105 W to 170 W. Expect the CPUs to heat up significantly under heavy loads.

Another notable new feature: RAM. The Ryzen 7000 actually manage DDR5, the new generation of Ram that offers much higher speeds than the DDR4 currently used on all current PCs. In the same way, they also support the PCIe (PCI Express) 5.0 standard instead of PCIe 4.0, which also offers higher transfer rates, allowing you to take full advantage of the new generation of high-performance SSDs.

Who says new support also says new chipset, the “set of chips” that manages the processor and the other elements on the motherboards. AMD has developed three new ones: the B650, the X670 and the lX670E, which are intended for entry-level, mid-range and high-end PCs, respectively. We should see them arrive quickly on motherboards from specialists of the likes of Asus or MSI.

iGPU: RDNA 2 standard in all Ryzen 7000

Furthermore, unlike the Ryzen 5000, all Ryzen 7000s seem to come standard with an integrated graphics circuit (known as an iGPU) that avoids the use of a dedicated graphics card, except for the most demanding gamers. And it will not be a discount area, since this module will be of the RDNA 2 type, in other words, the technology of the Ryzen 6000 but also the Steam Deck hybrid console or the essential Xbox series and the PS5, those with the AMD chip -Standard are equipped. However, due to a lack of details, we don’t yet know how many and how many graphics cores are installed. However, since an RDNA 2 core is up to twice as powerful as a Radeon Vega core, we can expect a very good level of performance, not to mention the reduced power consumption compared to a graphics card. Enough to be more than enough for most applications, including 3D in most games, which is no less beneficial in times of component shortages…

At the moment we do not know the exact composition of the Ryzen 7000 family, which, like all other product lines, will obviously evolve gradually. All we know is that AMD plans to release them in fall 2022. And we imagine the brand will be distilling more information by the launch date. We will have to be patient for the other technical aspects, but above all for the actual performance and prices. And this last point is particularly sensitive when we know that TSMC has decided to increase its prices. See you in a few months to see what the new AMD champions really are worth against the competition, as we suspect Intel won’t be sitting by. And that Apple is also preparing new chips with ARM architecture, which are even more impressive than the current M1s. Undoubtedly, after a few years of relative calm, the processor war is off to a good start!
