Dr. Lisa Su, the CEO of AMD, has today announced the company’s next generation mainstream Ryzen processor. The new family, known as the Ryzen 5000 series, includes four parts and supports up to sixteen cores. The key element of the new product is the core design, with AMD’s latest Zen 3 microarchitecture, promising a 19% raw increase in performance-per-clock, well above recent generational improvements. The new processors are socket-compatible with existing 500-series motherboards, and will be available at retail from November 5th. AMD is putting a clear marker in the sand, calling one of its halo products as ‘The World’s Best Gaming CPU’.  We have details.

Four Processors, All Coming November 5th

With the new Ryzen 5000 series, AMD is keeping a similar structure to the previous generation. The first four processors to market will include products in the key Ryzen 5 and Ryzen 7 segments, as well as a pair of high-performance parts with Ryzen 9. These will stretch from six cores to sixteen cores, with increased frequencies and increased performance-per-clock, but with no additional increase in power. The processors are still chiplet-based, with one chiplet having either six or eight cores. Ryzen 5 and Ryzen 7 will have one chiplet, while Ryzen 9 will have two chiplets – the easy way to identify this is through the amount of L3 cache each processor has.

Ryzen 5 5600X 6c/12t 3700 4600 32 MB 65 W $299*

*comes with bundled CPU cooler

Ryzen 9 5950X

Sitting on the top of the processor line is the new halo Ryzen 9 5950X. With 16 cores and 32 threads, it has a listed base frequency of 3.4 GHz and a boost frequency of 4.9 GHz. With two chiplets it has the full 64 MB of L3 cache, and the 105 W rated TDP is equal to the 16-core equivalent of the previous generation. This processor will retail slightly higher than the previous generation, with AMD making the move from $749 MSRP to $799 MSRP.

The Ryzen 9 5950X's main competition is either a AMD chip in the Ryzen 9 3950X, which currently retails for $710, or Intel's 18-core high-end desktop processor, the Core i9-10980XE, seen as low as $803.

Ryzen 9 5900X

The second processor is the Ryzen 9 5900X, which offers 12 cores and 24 threads, using two six-core chiplets and having a full 64 MB of L3 cache. With a base frequency of 3.7 GHz and a turbo frequency of 4.8 GHz, AMD is calling this processor the ‘World’s Best Gaming CPU’. This is likely because of the lower core count than the other Ryzen 9 allowing slightly higher frequencies when a game loads up several of the cores – the six cores per chiplet lowers the thermal density when running, enabling higher frequencies. The extended L3 cache per chiplet (explained later) reduces the effective latency by allowing more data to be stored before main memory access is required. This Ryzen 9 5900X also has a 105 W TDP, and the price of this 12-core is also slightly higher, moving from $499 MSRP to $549 MSRP.

AMD says that the Ryzen 9 5900X, at $549, is expected to compete directly against Intel's Core i9-10900K, which has an MSRP of $529. The Core i9-10900K is currently overpriced at retail, due to limited stock - the Core i9-10850K, which is around the $499 mark and available at retail, might be the more 'real world' competition.

Ryzen 7 5800X

The Ryzen 7 5800X is expected to follow in the footsteps of the popular Ryzen 7 3700X, which currently sits as #2 on Amazon’s best seller list. This is a single chiplet processor with eight cores and sixteen threads, running at 3.8 GHz base and 4.7 GHz boost. With it only being a single chiplet, it has 32 MB of L3 cache, but it has the 105 W TDP allowing for higher sustained frequencies. AMD believes that the increased raw performance of its product demands pricing more consummate with its position in the market, and so we see a slight MSRP increase from $399 to $449.

AMD expects that the Ryzen 7 5800X, at $449, is likely to be competing against Intel's Core i7-10700K, which has an MSRP of $409. In our recent guide, we've seen the i7-10700K retail at $380.

Ryzen 5 5600X

The base model at launch this time around is the Ryzen 5 5600X, with a single chiplet of six cores and twelve threads, running a base frequency of 3.7 GHz and turbo frequency of 4.6 GHz. This will be the only processor (at launch) with a 65 W TDP, and as such this is the one that AMD will ship with a bundled cooler. It takes over from the Ryzen 5 3600 family, which sits as #1, #3, and #7 in Amazon’s best seller list. With a $299 MSRP, it comes in again a little pricier than the parts it replaces; however AMD is promoting that in terms of performance per dollar, this mainstream component gives a lot more than its competition.

The competition for the Ryzen 5 5600X is likely to be Intel's Core i5-10600K, which has the same MSRP of $299. The i5-10600K can currently be found around that price, and does not seem to have moved much since launch.

AMD Ryzen 5000-Series Features

All four processors have the same official memory support at DDR4-3200, and the 105 W TDPs will offer a turbo power of 142 W, which is the same as the current generation Ryzen processors. AMD has decided to only bundle coolers with processors 65 W and under, citing that in its research that customers who buy the higher power processors almost always prefer to use their own cooler to eke out more performance when at full load. We were told that if they were to bundle one of AMD’s 125 W coolers with the 105 W processors, they would have to reduce frequency a little in order to compensate for the cooler being the lowest common denominator for those systems – those 105 W processor users, I was told, would much rather have the extra frequency and performance with their own cooler.

For the Ryzen 5000 series, AMD stated that the IO die is the same as the previous generation. There are still 24 lanes of PCIe 4.0 support, as well as the associated NVMe/SATA allocation. There was a note about 500 series chipset support and how customers can prepare for it, as well as upcoming 400 series support, which we’ll cover separately.

All four processors will be available, at retail and e-tail, on November 5th.

AMD told us that feedback they had received from the last generation launch, where the 16-core processor was announced later, motioned the company towards a unified launch. When asked if AMD could comment on stock levels on launch day, especially as we consider the company has lots of console processor orders at TSMC, future graphics hardware orders at TSMC, as well as future EPYC hardware in the mix, AMD declined to comment on the matter, except to say that they’ve been working hard with retailers and distributors to share best practice solutions when it comes time to dealing with bots and scalpers, to avoid a repeat of other highly anticipated hardware launches.

A word on naming. It might be easy to spot that AMD has bypassed the 4000-series for its desktop hardware. When quizzed on this matter, AMD’s Robert Hallock stated that as the company had already launched OEM processors with integrated graphics into the 4000-series naming, built on Zen 2, the company felt that in order to ensure that the new Zen 3 processors were easy to identify (or search for) that it should get its own naming sequence. What AMD did not mention that this also gives them an opportunity to unify its CPU and APU series codenames as-and-when Zen3 based APUs come along. There is also a third factor, in that the number 4 in China is often seen as an unlucky number due to the sound of the number being close to the sound of the Chinese word for ‘death’. The Chinese market has been a key growth market for AMD, and so aligning its latest generation hardware out of the ‘4000’ category will remove a potential negative to sales. This is also perhaps why so few of AMD’s processors contain the number 4.

A Promise of Year-on-Year ‘True’ Performance Growth

As part of the new Ryzen 5000 series announcement, AMD was keen to point out that it believes it is the only mainstream desktop processor company on the market with a year-on-year cadence of products that truly breaks new grounds for performance. The key highlight of the announcement is this +19% improvement in performance compared to the previous generation, which AMD says gives it a significant lead in overall single threaded performance, multi-threaded performance, 1080p gaming, power efficiency, and when combined with price, performance per dollar. AMD believes it has a full well-rounded product to beat Intel's best in the workloads that matter most to its users. It has been a long, long time since AMD has had the bravado to claim the top crown across the board.

The +19% value that AMD is using is taken from internal testing, using the geometric mean of 25 benchmarks involving a mixture of real-world and synthetic. AMD states that they compared the Ryzen 9 3900X, the previous generation 12-core processor, to the Ryzen 9 5900X, the new generation 12-core processor, both at 4.0 GHz fixed frequency and running DDR4-3600. Of that 19% number, AMD has attempted to break down where it believes these benefits have come from:

This equates as roughly:

  • +2.7% Cache Prefetching
  • +3.3% Execution Engine
  • +1.3% Branch Predictor
  • +2.7% Micro-op Cache
  • +4.6% Front End
  • +4.6% Load/Store

AMD did not want to go into specific details on how these numbers were achieved at this time, and stated that we would get time to go deeper into the microarchitecture ready for articles on the day that these processors come to market. What AMD did say however is that this new Zen3 core is a ‘front-to-back redesign’ over Zen2, and the key SoC innovation they did want to highlight was the new 8-core structure in each chiplet.

As expected in Zen 3, AMD has combined two four core structures (or core complexes, CCX) into a single eight-core structure. This means that all eight cores have access to the 32 MB of L3 cache inside a chiplet, and the latency for each core from 16 MB to 32 MB is greatly improved (previously when you went beyond 16 MB with a core, you would end up in main memory, which is comparatively slower and more power hungry). Due to the increase in L3 cache and the reduced cache latency in this 16-32 MB region, AMD is calling this an ‘effective reduction in memory latency’. No numbers were attached to this claim at this time, and AMD did not state if there were any specific microarchitecture changes in the cache hierarchy to assist with the larger cache access patterns.

But, what we can extrapolate is that whereas in the previous generation, because each chiplet had two core complexes, each complex had its own fabric connection to the rest of the chip. With a single eight-core unified complex design, there is now less core-to-core communication that's required to go off the chiplet. For single chiplet designs, this gets elimated completely, and for dual chiplet designs, each complex only needs to probe one other complex, rather than three. The peak bandwidth should still be the same however, but in a real-world scenario, there should be less cross-talk to deal with. This would scale better for the enterprise hardware, assuming it still retains the eight-chiplet design.

On process node technology, AMD clarified that these processors are using the same 7nm process that the company has contracted from TSMC as it did with the Ryzen 3000XT processors. Users may remember that AMD and TSMC were able to eke some extra efficiency from the base 7nm process, which was productized in the 3000XT family that launched mid-cycle. AMD is claiming that with this process for Zen 3, they can claim a 2.4x performance per watt improvement over the first generation of Ryzen, or a 2.8x performance per watt lead over Intel’s latest Comet Lake halo processor. We will have to test this when samples arrive.

We are waiting for access to engineers for a fuller breakdown of AMD’s Zen3 microarchitecture. You should expect to see our analysis as part of our launch day reviews on November 5th.

    "But people making a Ryzen build from scratch would need a new motherboard anyway"

    But the millions and millions who already have a AMD X570/B450/A420 platform, won't, so that's a $300 saving for them!

    "only the 5600X comes with a bundled cooler, the 5800X would give you such an expense as well"

    Err, nope! Point to a single review that shows how a Ryzen CPU draws 229 Watts in normal usage! Unlike an Intel CPU, you can save $100 just on the cooling! Like I said, you can save that amount too on Intel, butthen again you can forget about that Turbo boost speed, and your CPU will run like a $150 AMD one!

    Don;t get me wrong, until 5th November, there are reasons to have bought an Intel CPU, and maybe after 5th November there might be reasons to still buy one, but the use case will be so niche after that date, you've got to have reasons you so far haven;t been able to articulate.

    Its not good to fan-boy a company, any company. I've owned both Intel and AMD, but really I can't see anyone but Fan boys highlighting Intel from next month, as to so so makes no sense! I'm running a 3950X right now, and this launch gives me no compelling reason to upgrade, but would I buy Intel, nope! Too expensive, to restrictive an eco-system (try getting 3200Mhz memory on a H series motherboard), and too high a TDP, and from whats happened today, at best they now tie with AMD.

    Intel were wee-weeing and laughing at AMD three yars ago about their 'glued together CPU', when the market place was crying out for more cores...

    Intel is reaping what it sowed, nothing more nothing less and to shill form them appears at best daft to me...,
  • Gio97BR - Thursday, October 8, 2020 - link

    But if you're already on AM4, it's not like it would make any sense to consider going Intel.

    People who will have to choose between those two platforms for a new build are those who don't have an AM4 chipset. That's why I didn't take that as an argument for Zen 3's value proposition.

    About cooling the 5800X versus the 10700KF... Look, the 10700KF really does require better cooling to properly boost. However, if you're spending $450 on a CPU will you really go cheap on it's cooling system? Specially with AMD insinuating that the Wraith Spyre would not unleash the 5800X's full potential?

    I don't think that you will spend $100 more in cooling by getting a 10700KF. So your build will also likely remain cheaper overall. If your sole purpose is gaming I don't think that long-term electricity bills will by themselves justify the more expensive option.

    And look, I'm not an Intel fanboy. My gaming rig is Ryzen based, and the 5900X is the most appealing CPU available IMO. But I'm not an AMD fanboy either. I'm very annoyed by fanboyism.

    That's why I started commenting here after getting quite bothered by people accepting a 20% price hike on the lower-end models and applauding AMD unconditionally as if they were cattle. It's because of fans like those (and corrupt press) that Intel and Nvidia kept milking customers generation after generation when they had no real competition.

    I'm glad that Anandtech noticed the hike and interrogated AMD on this topic. Otherwise, it could have been part of the problem, such as Tom's Hardware saying "just buy it" about Nvidia's Turing, when that generation brought an almost null performance increase over Pascal, dollar per dollar.

    I understand why you dislike Intel, and I dislike it too. But I don't think this is a good enough reason to unconditionally pander AMD.
  • Notagaintoday - Thursday, October 8, 2020 - link

    getting quite bothered by people accepting a 20% price hike on the lower-end models and applauding AMD unconditionally as if they were cattle"

    Not sure why? AMD had to artificially lower heir prices to compete with the Intel fanboys. The 1800X was launched at $499 I think, but within weeks was at $449, and within a few months was selling at $399.

    AMD haven't been able to hold their price in the face of fools/idiots buying Intel, "cos its the fastest in'it"?

    Even though AMD has been outselling Intel by 90% in market share, it has only been getting 60% of the total CPU spend (see Mindshare's charts). Intel is still raking it in, because consumers spend more with Intel. Look at the 7980XE; $2,000 !!!

    If AMD is to succeed with Zen 6 and if there is to be a Zen 8, AMD needs that additional revenue, it needs to drive its R&D. Intel still outspends AMD on R&D by an order of several magnitudes. Intel's spend on R&D is more than AMD's entire income for the year!

    Intel will recover, 2022 looks likely for 10nm to be ready, and even if it isn't Intel's 7nm will likely launch 2022/23 and that will likely beast AMD at 5nm, and unless you want there to be a return of Intel again in the driving seat for another 10 years of stagnation, you'll pay the slightly higher price, or you'll wait a few months for supply to outstrip demand and pay the lower price...

    If you persist in demanding always lower prices, you'll be left with just Intel... Then you'll have reason to complain!

    Rather than complaining abut AMD, maybe complain about the fools that have caused this; the idiots paying $2,000 for a gaming CPU that have given Intel a massive financial cushion so large they can lose 90% market share in the enthusiast space, and still not care! Its just like the idiots paying $1,500 for a GPU...

    Its not AMD's fault that people are stupid, so complain about the stupids, not AMD!

    Really, like AMD was trying to beat Intel for the last 10 years. You think Intel will slap together a chip that will out do AMD in a few years. I think you are dreaming. Intel stuck with 14nm and milk as much as they can on consumers. Oh, they can't even do 10nm for that matter and you think 7nm cpu process. You are right, I don't want to pay $2000 intel 10cores cpu but I will buy 16 cores AMD for $800.
  • Stu7nm3dflash - Thursday, October 8, 2020 - link

    Yeah, I’ve got a B450 MB, Ryzen 3 3100, I wanted some 7nm, but as I increased my ambitions, I wound up with enough components to make another cheap computer. I should have waited till the 4000 series APU, mini PCs came out. $A600, I guess that’s $US440, for the bare bones, another $A400, $US300, for the laptop RAM 16GB, PCIe 3 flash 500GB, 1TB flash drive. So much less work and money, but it’s always this way, I can one day get a 5000 series APU.

    Maybe I’ll get a 7nm graphics card, I was just tempted to go back into the game, by my iPad mini 5 having a 7nm chip, at 6.9 billion transistors and 5 trillion floating point operations, per second. Things haven’t changed much in the last 7 years. RAM is only double the speed, flash triple the speed, nearly quadruple the speed on the processor, those stupid case to motherboard pins, that you can hardly read, with glasses, a torch and a motherboard manual.

    But I did get a factory reset down to 18 minutes, good fast memory, can pass even Microsoft’s bloat ware, through billions of transistors at teraflops, it’s still obsessing though, set top boxes, tablets are more convenient. A new XboxS, can crunch 5 teraflops, with it’s 16GB of GDDR6, 8CPU cores who knows how many GPU cores, fast flash, for $US 299 I think.

    "Unlike an Intel CPU, you can save $100 just on the cooling!"

    You can buy a Noctua NH-D15 for <$100 and cool any of these CPUs from either Intel or AMD. Not sure how you'd save $100 when the cooler costs less than that.
  • lmcd - Thursday, October 8, 2020 - link

    There was 0 good reason to buy X570 at launch and B550 barely launched in the last half year. The only people desperate for PCIe 4.0 wanted it for storage bandwidth, which is niche as can be. That leaves the people with a beta bios for their upgrade path. A good value proposition once it's done, but Rocket Lake will be out practically by the time those beta bioses are trustworthy.
  • Spunjji - Friday, October 9, 2020 - link

    lmcd in with the goalpost move as per usual.

    "It may be better, but here are some reasons why I'd rather wait for an Intel product that won't be out until at least 2 months later and will almost certainly be slower with higher power draw".
