AMD Ryzen 7000 with Zen 4 architecture officially announced: 5 nanometers and up to 16 cores

AMD Ryzen 7000 with Zen 4 architecture officially announced

In the middle of the night, at least for us inhabitants of the old boot, AMD presented the first high-performance desktop processors of the new AMD Ryzen 7000 series: four models arriving on September 27 based on the Zen 4 architecture, an evolution of the previous Zen 3, and capable of a net performance increase accompanied by a leap forward in efficiency thanks to the optimizations of the new AM5 platform and the use of a 5-nanometer production process.

Starting with the AMD Ryzen 9 7950X, equipped with 16 cores and 32 threads, to arrive at the AMD Ryzen 5 7600X, the one with 6 cores and 12 threads closest to the typical needs of gamers. In between we find the AMD Ryzen 7 7700X, for those who need a little more raw power but don't want to spend a fortune, and the AMD Ryzen 7 7900X, a 12-core, 24-thread processor that cannot compete in overall power with the maximum weight of the series but still offers a high computing power and sufficient to satisfy even high-level professional needs.

Hardware features

AMD CEO, Lisa Su, presented the new AMD Ryzen 7000 processors The classic short premiere dedicated to the AMD Ryzen 7000 processors, as per tradition conducted by the CEO of AMD and CPU heroine Lisa Su, had almost absolute protagonist the AMD Ryzen 9 7950X, the top of range of the new series that reaches 5.7 GHz in boost clock against 4.9 GHz of its predecessor despite the new series is an evolution of the old one. But behind the scenes there are other innovations, valid for the whole series, which include universal support for DDR5 memory at 5200 MHz to get to the standard PCIe 5.0 interface, increased frequencies and surprisingly unchanged or lower recommended prices despite the complex situation. world economy.

Specifically, the amount necessary to get an AMD Ryzen 5 7600X at home, recommended price 299 dollars, does not change, nor for the AMD Ryzen 9 7900X, recommended price 549 dollars, while it drops by as much as 100 dollars for the AMD Ryzen 9 7950X, MSRP of $ 699. All this is assumed to be fanless for the top models and fanless in the case of the AMD Ryzen 5 7600X, as for the previous series. We do not know instead what to think of the AMD Ryzen 7700X since the AMD Ryzen 5700X came out late and without a heatsink included, but it is likely that this new model will replace the AMD Ryzen 5800X, costing 50 euros less. In any case, we will undoubtedly come back to talk about all this as soon as we have some more official data.

No price increase for the AMD Ryzen 7000 processors. Indeed, the top of the range drops by $ 100 In all this , we have already said, the number of cores remains unchanged compared to previous models, unlike what has been done by the competition, but the structure of the cores changes, data management improves, production nanometers decrease to 5 and change the cores, a fundamental piece of a family of processors that offers up to 29% more single core power thanks to optimizations, has a doubled L2 cache that reaches 1 MB for each core and implements substantially higher frequencies for all processors. The AMD Ryzen 7600X, in fact, reaches 5.3 GHz, the AMD Ryzen 7700X goes one step further by touching 5.4 GHz, the AMD Ryzen 9 7900X launches up to 5.6 GHz and the AMD Ryzen 9 7950X, the we have already said, it reaches 5.7 GHz. And it is to the high frequencies that we owe the increase in the TDP which rises from 105 W to 170 W for the two top models and from 65 W to 105 W for those with 6 and 8 cores.

But there is also talk of greater overclocking margins for processors that keep up with the times also in terms of support for acceleration through artificial intelligence and the integration of AVX-512 instructions. Finally, when evaluating the prices, it is necessary to take into account how, for the first time, even the high-performance Ryzen CPUs for desktops have an integrated GPU, even if lower power than those of the latest generation AMD APUs.

Missing altogether, unfortunately, is the futuristic 3D V-Cache stacked cache, apparently coming to a number of new models over the next year, capable of delivering a noticeable performance boost in video games. Someone already talks about a 7800X3D that will become the perfect replacement for the 5800X3D with a focus dedicated to the most demanding gamers. In any case, the push forward of the frequencies and the optimization of the Front End pipeline still promise net performance increases even in gaming, without the need for memory that would probably have led to significantly higher prices. But before talking about performance in the field let's talk about the new chipsets and therefore the new X670 and B650 motherboards. ! function () {"use strict"; window.addEventListener ("message", (function (e) {if (void 0! == e.data ["datawrapper-height"]) {var t = document.querySelectorAll ( "iframe"); for (var a in e.data ["datawrapper-height"]) for (var r = 0; r

AMD 600 series motherboards

The MSI's new X670 motherboards for AMD Ryzen 7000 processors The use of the new AM5 platform, which therefore forces you to buy the new motherboards in order to take advantage of the 7000 series processors, does not translate into an entirely new architecture. Zen processors 4, as we have said, are an evolution of the previous models, but it is an important evolution that includes advanced features, DDR5 memory with a native frequency of 5200 MHz, standard PCIe 5.0 interface, 5-nanometer FinFet transistor and the new socket LGA socket 1718, however compatible with cooling systems for AM4 motherboards, which thanks to the increase in pins can guarantee up to 230 W of power supply. Abb therefore, to give ample room for maneuver, in terms of overclocking, even with TDP's 170 W models.

At the launch of the new AMD Ryzen 7000 processors, only the AMD X670 motherboards will be available, in arrival in September, but the B650 models will already be available in October and will be cheaper, with prices starting at 125 dollars in the face of some sacrifices in terms of performance and overall connectivity. We still do not have precise numbers in this regard, but as usual we speak of a smaller number of PCIe lines and therefore of some renunciation also in terms of connectivity. Furthermore, only the B650 Extreme models will enjoy PCIe type 5.0 slots potentially useful for future GPUs, while its presentation will be standard for X670 motherboards. The basic models, on the other hand, will be satisfied with PCIe 4.0 slots, but will still be able to take advantage of a PCIe 5.0 SSD, which should also be supported as standard by future A620 motherboards.

The new memory with technology AMD EXPO

The new AM5 platform for AMD Ryzen 7000 processors includes one-click EXPO overclocking technology Finally, there is another platform-side innovation regarding AMD EXPO, the new one-click RAM overclocking technology that promises reduced latencies and up to 11% more performance in 1080p games thanks to an architecture that, like the previous one, is heavily influenced by the memory clock. But this is, it must be said, an optional choice for memory kits, initially 15, which in all probability will cost more than those compatible with the classic XMP technology, however fully supported by the new AMD platform. The frequencies will be 6000 MHz in this case, with some kits capable of going up to 6400 MHz base.

Performance

The internal benchmarks of the AMD Ryzen 9 7950X, top of AMD Ryzen 7000 series range AMD apparently managed to achieve 13% more instructions per clock, clearly beating initial predictions of 8-10% leap forward. A particularly relevant figure given the increase in frequencies that come to increase by 29%. Enough to get close to the speeds expected for Intel's future 13th generation CPUs that it could struggle with such a major leap despite a less advanced paper architecture. But we will talk about this with the processors in our hands. For now we are forced to rely on the numbers communicated by AMD which speak of an increase in performance in the order of 29% in single core, 44% in multi core and 25% speaking of performance per watt. A nice leap that should guarantee 35% more overall power at 170 W, 37% more at 105 W and, very interestingly, thinking about future low-power models and the mobile environment where AMD could give another very important paw, up to 74% more with the wattage at 65 W.

Obviously, these are values ​​that must be taken with a grain of salt when talking about actual performance, given the large number of variables which also include any bottlenecks and actual CPU utilization when the GPU takes care of the bulk of the load, but we are still talking about important numbers in video games, where in the titles chosen by AMD, the Ryzen 9 7950X outperforms the Ryzen 9 5950X by a average of 15%, and the results exceed expectations even in content creation, with the new top of the range exceeding its predecessor by 40%. In this case the average is raised by the stratospheric values ​​of the V-Ray software, where we are talking about a 48% more performance staying at home and a 62% more than what is obtained by the current top of the range of Intel, but the performance increases are also very high in Corona Render, with 32% more performance, in Arnold Renderer, with 37% more performance, and in POV-Ray, with 45% more performance.

The internal benchmarks on the gaming side of the AMD Ryzen 9 7600X, the closest to the needs of the players of the AMD Ryzen 7000 series Returning to gaming, we are talking about peaks up to 32% with DOTA 2 and up to 35% with Shadow of the Tomb Raider, again talking about the AMD Ryzen 9 7950X which compared to the Ryzen 9 5950X also grabs 6% more frames in Borderlands 3 and 13% more in CS: GO. But in the case of video games we also have some numbers related to the AMD Ryzen 5 7600X, apparently able to surpass the Intel Core i9-12900K by 11% in F1 2022 and by 17% in Rainbow Six Siege, to tail it in GTA V with 3% less performance and even the score in Cyberpunk 2077, a problematic title with previous AMD Ryzen processors.

The future of AMD Ryzen processors

The first processors of the AMD Ryzen 7000 series do not mount 3D V-Cache, but will arrive with new models in the course of 2023 Although focused on the processors arriving on September 27, the small pre-recorded conference of AMD also gave us some information on the future moves of AMD starting with the mention of 4 families of Zen 4 processors and the new SoCs with XDNA architecture. Furthermore, the compatibility of the AM5 platform with the processors of the next few years has been guaranteed, at least until 2025. The motherboards arriving in the next few days will therefore be able to mount both the future Zen 4 processors with 3D V-Cache, arriving in 2023, and the Zen 5 processors, arriving in 2024 as expected, as well as presumably the refresh of the latter. And as the icing on the cake, the AMD CEO assured that AM4 solutions will stay around for a while longer, so as not to suppress the existing ecosystem.

Future RDNA 3-based GPUs

AMD RDNA 3 promises 50% more performance per watt than the previous RDNA 2 architecture But the most relevant anticipation came at the end, with the appearance of AMD RDNA 3 GPUs that will arrive by the end of the year, as confirmed by an enthusiastic Lisa Su who took the opportunity to show a prototype of the new GPUs grappling with Gamescom 2002's most popular title, Lies of P, in 4K with maximum graphics settings. Unfortunately, there was a lack of information on framerate, model name (let's imagine it is the 7900XT), brute power or AI-based upscaling technologies, but at least the AMD CEO confirmed a 50% increase in performance per watt it leaves. assume a net increase in bare and raw performance. We are therefore preparing for a leap forward for the entire ecosystem as we wait to get our hands on the new AMD processors so we can talk to you in more detail.
