AMD’s new Zen 5 Ryzen 9000 processors are simply across the nook, and at present we are able to reveal a bit of extra details about them. As a fast recap, AMD introduced the Ryzen 9000 collection at Computex final month. This consists of 4 major desktop processors in a fairly commonplace line-up: the Ryzen 9 9950X, Ryzen 9 9900X, Ryzen 7 9700X, and Ryzen 5 9600X.
The primary profit we’re getting here’s a 16% common IPC uplift, just like AMD’s earlier Zen structure upgrades. Different elements of the design stay unchanged from Ryzen 7000, together with the variety of CPU cores (which continues to be between 6 and 16 throughout the line-up) and peak frequencies that push as much as 5.7 GHz. There are additionally no 3D V-Cache fashions as of but, that means the preliminary batch of Zen 5 CPUs tops out at 32MB of L3 cache per CCD.
We now have a launch date for these processors: July 31, 2024, proper on the finish of AMD’s preliminary July launch window. What we do not have, although, is pricing, which is a bit unusual, to be sincere. AMD goes to start promoting these processors in simply over two weeks, and there is not any indication of how a lot they will price or how a lot consumers might want to save as much as seize Zen 5. In distinction, when Zen 4 was introduced in 2022, we had full pricing and spec info almost a month earlier than launch.
However we additionally do not actually know what this implies or how a lot to learn into it. Often, when an organization would not wish to disclose particular info, it is as a result of the reply is not very constructive.
Many of the Zen 4 line-up is now discounted under its preliminary launch MSRP, generally by tons of of {dollars}, just like the 7900X, which you’ll be able to seize proper now for simply $360. So, early pricing comparisons to full-MSRP Zen 5 fashions won’t be all that favorable. But it surely may be the case the place pricing is kind of aggressive, and AMD would not wish to cannibalize Zen 4 gross sales over the subsequent few weeks. Apparently, we’ll get pricing in time for critiques, however proper now we’re nonetheless at nighttime.
New efficiency claims for Ryzen 9000
What we’re getting at present are extra first-party efficiency slides. Again at Computex, we acquired very restricted efficiency information, largely specializing in the Ryzen 9 9950X in comparison with the Core i9-14900K. Now AMD is increasing these comparisons to incorporate the opposite fashions.
Most of those slides are fairly typical within the info they supply. The six video games proven for every comparability are the identical throughout all fashions. AMD is promoting that the 9950X is, on common, 13% sooner than the 14900K for gaming throughout these titles, although, as at all times, first-party benchmarks must be taken with a grain of salt because of the degree of cherry-picking that could be occurring with simply 6 titles. With the Ryzen 9 9900X, AMD suggests 12% extra efficiency than the 14900K, which ought to imply very related gaming efficiency to the 16-core mannequin.
With the 9700X, AMD is now evaluating it to the 14700K, once more exhibiting a 13% efficiency enchancment for the Zen 5 half. The 9600X is anticipated to be 14% sooner than the Core i5-14600K based mostly on this knowledge as nicely.
What’s maybe extra attention-grabbing are the productiveness numbers, which look like extra considerably cherry-picked. For instance, with the 9900X versus 14900K, AMD reveals Blender as one instance of better efficiency, however with the six and eight-core fashions, that benchmark is swapped out for 7-Zip, often fairly a good benchmark for AMD CPUs. There’s additionally a heavy concentrate on single-threaded outcomes like Procyon Workplace, Geekbench, and Photoshop versus multi-core duties, outdoors of Handbrake which is anticipated to profit considerably from Zen 5’s AVX-512 assist.
Studying between the traces, this means Ryzen 9000 CPUs won’t be as aggressive for multi-threaded workloads in comparison with single-threaded workloads relative to the closest Intel elements. E-cores are a major a part of Intel’s structure that help massively with multi-threaded productiveness apps: the 14700K options 12 E-Cores along with 8 P-cores, and the 14600K provides you a 6P+8E configuration. This may possible see Intel preserve their multicore productiveness lead; beforehand we discovered the 14600K to be over 50% sooner than the Ryzen 5 7600X in some workloads like Cinebench multi-core, which is a big hole to bridge in a technology that sees no improve to core rely.
AMD additionally in contrast the Ryzen 7 9700X to the Ryzen 7 5800X3D, claiming the brand new Zen 5 half is 12% sooner on common than first-gen 3D V-Cache fashions whereas utilizing much less energy. That is an attention-grabbing comparability given it is successfully Zen 5 versus Zen 3, not a comparability to the newer Zen 4-based 7800X3D. Nevertheless, AMD did additionally point out {that a} related comparability to the 7800X3D would present the brand new 9700X coming in “a few proportion factors” sooner.
All of those claims do not totally align with our present CPU gaming knowledge, which discovered that the Ryzen 7 5800X3D is a bit of slower than typical Zen 4 non-X3D processors. It’s 4% sooner for the 7600X versus 5800X3D, and eight% sooner evaluating the 7700X versus 5800X3D. There’s little to no crossover within the video games examined between our take a look at suite and AMD’s – and we use an RTX 4090 whereas AMD sometimes makes use of a Radeon RX 7900 XTX – however this could indicate solely a small improve in gaming efficiency for the 9700X over the 7700X.
On the identical time, for the 9700X to be 13% sooner than the 14700K throughout a variety of video games, it will really be sooner than the 7800X3D in our knowledge and over 30% sooner than the 5800X3D. It is laborious to know precisely the place issues will land given AMD does declare the 9700X is barely sooner than a 7800X3D. I suppose you should not actually belief first-party benchmarks, but when this had been to be true, the hole to the 5800X3D must be greater, making at the very least one of many claims AMD has made a bit contradictory to the others and our testing.
With all of that stated, AMD did evaluate Ryzen 9000 to Ryzen 7000 instantly in Blender multi-thread, claiming quite a lot of efficiency features whereas additionally boasting decrease TDPs. However there’s an essential reminder right here: TDPs aren’t an precise measurement of energy consumption, merely a score for required cooler efficiency. Simply because the Ryzen 5 mannequin drops from a 105W TDP to 65W TDP whereas enhancing efficiency by 17%, doesn’t suggest the precise energy consumption of these elements has decreased by 40 watts.
New Zen 5 CPU options
So what else is new to find out about Zen 5 processors? Effectively, AMD is anticipating first rate features from utilizing Precision Enhance Overdrive, particularly for the Ryzen 7 9700X. There have been some rumors claiming that AMD was going to lift the TDP of the 9700X on the final minute from 65W to one thing greater like 120W, however this isn’t the case based mostly on the data AMD is exhibiting simply two weeks out from launch.
As a substitute, AMD is claiming that because of decrease default TDPs, PBO goes to offer extra additional headroom than typical, particularly for the 9700X the place they’re claiming a 15% efficiency improve.
Ryzen 9000 processors will run cooler than Ryzen 7000 because of a 15% enchancment in thermal resistance, which AMD claims will lead to a 7-degree Celsius temperature discount on the identical TDP.
Typically, Zen 4 processors had been straightforward to chill because of solely reasonable energy utilization, particularly in comparison with Intel’s 14th-gen, however they did run upwards of 90C underneath full load. It is a good profit for people who find themselves temperature delicate and nervous about cooking their CPUs, and it also needs to permit CPU frequencies to run greater at a given temperature.
There are further overclocking enhancements, particularly for reminiscence. Base JEDEC reminiscence assist has elevated from DDR5-5200 in Zen 4 to DDR5-5600, and there is OC assist as much as DDR5-8000, which AMD tells us is definitely achievable in real-world workloads, however the candy spot will likely be decrease. However essentially the most attention-grabbing inclusion right here is one thing referred to as Reminiscence Optimized Efficiency Profile.
Principally, what this implies is that reminiscence frequencies and timings will be adjusted on the fly relying on the workload. This permits the advantages of high-frequency reminiscence and low-latency reminiscence without having to always tweak issues within the BIOS.
The best way it was defined is that if you buy a high-end reminiscence package, e.g., DDR5-8000, in some workloads, it will push the frequency proper as much as 8,000 pace at looser timings like CL38, as a result of often when operating at greater speeds you possibly can’t have tremendous tight timings.
However then for some video games, for instance, the system will mechanically decrease the frequency and tighten timings if crucial. That approach your DDR5-8000 package would possibly really be helpful throughout a broad vary of use circumstances as a substitute of being a bit ineffective for gaming because of looser timings and worse latency. We’ll need to see how efficient it’s and the way nicely it tunes reminiscence on the fly.
For processor overclocking, there’s additionally an evolution of the curve optimizer characteristic referred to as curve shaper, which permits for extra management over the voltage-frequency curves at differing working temperatures.
Zen 5 structure
AMD made a number of deeper disclosures on the Zen 5 structure, the highlights are a full 512-bit knowledge path for AVX-512 directions, a rise within the L1 knowledge cache from 32 kB 8-way to 48 kB 12-way, a doubling of the utmost L1 cache bandwidth, and higher department prediction.
There’s a rise from 6-wide dispatch in Zen 4 to 8-wide dispatch, a rise in ALUs from 4 to six, and there is now a twin decoding pipeline within the entrance finish.
That is how AMD sees every of those architectural enhancements impacting the ultimate IPC and general efficiency. The massive driver of features has been the enhancements to execution and decoding, with knowledge bandwidth additionally a major issue.
New AMD B850 and B840 chipsets
AMD has introduced two new chipsets becoming a member of the 800 collection. At Computex, we acquired X870 and X870E as flagship chipsets and noticed loads of new boards throughout the varied distributors. Now AMD can be disclosing the extensively rumored B850 and B840 chipsets, with a breakdown seen on this useful desk.
The fundamentals are that X870 and X870E mandate USB 4 and PCIe 5.0 for graphics and the first M.2 slot. B850 reduces the necessities for each to USB 3.2 20 Gbps and PCI 5.0 only for the first NVMe drive, with 5.0 for graphics being non-compulsory. B840 cuts issues again additional, solely supporting PCIe 3.0 as a substitute of 4.0 because the baseline, dropping USB 3.2 assist right down to 10 Gbps and eradicating assist for CPU overclocking.
So the place do issues fall in comparison with the present 600 collection?
AMD X870 and X870E are a step up from the X670 collection in that each one boards will now assist USB 4, and the non-E boards may have extra PCIe 5.0 connectivity. B850 is a mix of B650 and B650E however largely a refresh of that chipset.
B840 finally ends up a tier under A620 – whereas each chipsets drop assist for overclocking and scale back USB speeds to 10 Gbps, B840 additional reduces the PCIe bus to three.0 whereas A620 stays PCIe 4.0. With that stated, different elements of B840 may find yourself a tier above A620, such because the variety of USB ports which are supported. All 600 collection chipsets assist reminiscence overclocking.
AMD additionally says that new boards have improved reminiscence routing to permit for extra dependable reminiscence efficiency at greater speeds, like DDR5-8000 that was beforehand talked about, though we’ll need to see which boards obtain these enhancements. Nevertheless, as talked about at Computex, these new 800 collection motherboards is not going to be launched alongside Zen 5, as a substitute coming a number of months later.
Lastly we additionally acquired a minor roadmap replace, with a slide that includes Zen 6 on it. Completely zero different particulars so it is actually only a hype slide to be sincere, no indication of after we can anticipate Zen 6, or what kind of course of node it is utilizing, simply nothing right here to go on by any means which is a bit of laughable.
All AMD has stated is that Zen 6 is on observe, no matter which means. The hole between Zen 3 and Zen 4 was roughly 22 months, and there is the identical 22 month hole between Zen 4 and Zen 5. Primarily based on that we must always anticipate Zen 6 in Could 2026 at a whole guess.
And that does it for at present’s Zen 5 information. In just some weeks, it’s best to see our full critiques of those processors together with loads of follow-up content material within the months to comply with.
