Synthetic single and multi-core benchmarks test the performance of specific instruction sets and processor operations like floating-point calculations using benchmark tools like GeekBench, Cinebench, and PassMark. Editors' Note, March 2, 2023: Some scrutiny by Tom's Hardware scrutiny by Tom's Hardware and online commenters pointed out that our integrated graphics (IGP) testing numbers for the earlier Ryzen 9 7950X chip were unnaturally low; this was likely due to early-driver issues that only became evident with this review of the 7950X3D, and made the 7950X3D's IGP look like a leap forward by comparison. We have retested the Ryzen 9 7950X and updated the numbers in the IGP testing table here and in that original review, and made minor tweaks to this article's intro and IGP Testing section to reflect the new numbers. We'll also be retesting the IGPs on the Ryzen 7 7700 and 7700X in the coming days. The original, fundamental conclusions we made about this chip, though, have not changed.]
Creative performance is a measure of how well the processor performs in several popular creative workloads like Handbrake, Blender, and Adobe Photoshop. Where possible, I explicitly disable GPU accelerated operations or test rendering using the CPU by itself. I already have DDR4. AMD expects me to just throw this into the trash and buy expensive new DDR5 for a 1% difference in performance. It even bothers me from an e-waste perspective, let alone the financial cost. Jan 5th 2023 AMD Confirms Ryzen 9 7950X3D and 7900X3D Feature 3DV Cache on Only One of the Two Chiplets (164) You'll also benefit from the advantages of AMD's next-generation 3D V-Cache technology, ensuring minimal latency and further elevating your gaming experience.

AMD Ryzen 9 7950X3D: Best CPUs UK However, AMD later retracted this as an internal issue, stating that more information on the release date would be unveiled shortly, but that the official debut month will remain as February. We now know, the release dates are as follows:
Frequently asked questions
The latest CPUs in the AMD Ryzen 7000 Series are here. Teased at CES 2023, the X3D Ryzen 9 models are finally hitting the shelves!As of April 6 th, we now also have an X3D Ryzen 7 model too! If the software detects a certain high level of thread utilisation, however, it will spin up that dormant chiplet and bring it online if its extra core count is needed. Underneath the integrated heat spreader (IHS), the Ryzen 9 7950X and Ryzen 9 7950X3D are very similar. You'll see a large central die on both chips, called the IO die, which contains an integrated graphics processor (IGP), the PCI Express controller, and other important components. AMD also includes two core complexes (CCXs) inside of each of these chips that hold the actual CPU cores and the cores' associated cache. Gaming performance measures how well the processor calculates gaming operations like in-game physics by running several games' integrated benchmark tools like Returnal, Total War: Warhammer III, and F1 2022. In all cases, I run the benchmarks on the lowest graphics settings available at 1080p and using the most powerful graphics card I have available (in this case, an Nvidia RTX 4090) and with 32GB DDR5 RAM to isolate the actual CPU operations I am testing without having to worry about inteference from excessive memory or graphics management. The amount of cache on CPUs has grown over time usually by very small steps, but there have also been a few times when AMD and Intel have significantly jumped up the amount of cache in an effort to boost performance. These efforts in the past have seen mixed results with, at the best of times, a modest performance gain occurring and, at the worst of times, nothing really changing. In part, the mixed results are due to software development, as apps need to be explicitly programmed to take advantage of the added cache for a noticeable improvement to occur.
The tuned setting did deliver higher performance, but only in the same way you can tune an F1 car to run above tolerances only to explode as it crosses the finish line. I could catch some higher benchmark numbers, but the system was in no way stable. Both the 7950X3D and the 7900X3D have two eight-core Core Compute Die (CCD) chiplets, marking the first time AMD has brought the 3D V-Cache tech to a multi-CCD processor. The above image shows that AMD only mounts a single 7nm SRAM chiplet atop one eight-core CCD, leaving the other CCD bare. The score in 3DMark obtained by the Ryzen 9 7950X3D is slightly lower than the one obtained by the Ryzen 9 7950X, but by so slim of a margin that it's essentially a tie. These two chips tie in other tests as well but, in F1 22, the Ryzen 9 7950X3D holds a decisive advantage over its similarly named counterpart while also narrowly passing the Intel competition. The cache clearly does not help enough to give the Ryzen 9 7950X3D the performance advantage in any other CPU test in our suite. At the same time, its lower TDP and heat limit cause the 7950X3D to operate a bit slower and perform worse in almost every test except that one. The Ryzen 9 7950X is slightly faster in many of these tests, but, considering how much cheaper that chip is at list price, it’s a bit of a no-brainer which is the better value in this scenario. When you factor in the cost of upgrading to the new AM5 platform, the Ryzen 9 7950X3D only makes sense if you are upgrading from an AMD Zen 3 or 11th-gen Intel processor or earlier, since you'll need to buy a whole new setup to get a newer processor from either brand. If you've got a 12th-gen Intel chip, though, making the jump to the AM5 platform for this processor alone is going to be a pricey upgrade.On the other hand, when a game like Total War: Warhammer III is running, energy efficiency on the 13900K goes right out the window and you start getting power draw above 330W just for the processor. This allows the 13900K to eke out up to 68 more fps than the 7950X3D (or 532 minimum fps for the 13900K to the 7950X3D's 464 minimum fps), but it literally needs almost 2.5 times as much power to accomplish this. You can refer to the spec table below to see how the full Ryzen 7000 lineup compares. Note that UK prices weren't included in the press release we received, but we're following up with AMD about this and will add this information if we get it. Testing a processor is arguably one of the most involved processes of any component I review because there are so many things to measure and quantify.
Compared to the more expensive chipsets, the AMD Ryzen 9 7900X3D absolutely holds its own with the 7950X3D and the 13900K, with the largest gap visible seen with how AMD's flagship handles Returnal. This is likely due to the fact that the 7950X3D utilizes an additional four cores and eight threads, and Total War series has always been Intel's strongest gaming benchmark, which remains the case here. While a higher TDP usually relates to higher performance, the inclusion of the added 3D V-cache means that the processor can access a larger pool of superfast cache memory, which is even more useful when gaming than just throwing raw power at the problem. With its own dedicated extra cache, there are fewer fetch operations to the PC's main memory, so the chip runs more efficiently, and potentially cooler under load. In most CPU tests, however, the cache is not that helpful, and this is what paints the worst picture of the Ryzen 9 7950X3D. Out of all of our CPUs tests, the Ryzen 9 7950X3D is beaten by the Ryzen 9 7950X in all of them except one. That one is the single-threaded POV-Ray 3.7 test, and admittedly that's within the margin of error. And this test highlights that even at 1440p the extra L3 cache of the 7950X3D tangibly makes a difference to the gaming performance of the system at the highest graphical presets. But, as always, at 4K it's all about the GPU. Metro is the only benchmark that displays some difference between the three chips attached to the RTX 4090, and then that's more down to some vagaries in optimisation and drivers.Curious as to what games are struggling to run on PC and also what PCs are struggling to run games? Also, are those affected games also having issues on consoles?
AMD's Ryzen 7000X3D gaming-focused processors finally have a release date - or rather, two release dates. The Ryzen 9 7900X3D and 7950X3D will debut on February 28th, with the 7800X3D arriving on April 6th. Only fusing the SRAM onto one CCD also reduces manufacturing costs, as the hybrid bonding process and additional chiplet make this an expensive technology. AMD also says that using two V-Cache chiplets doesn’t provide enough performance uplift to justify the extra costs. Or maybe the Ryzen 9 7900X3D or Ryzen 7 7800X3D might be. I've yet to test the other cache-heavy chips, but if they can deliver the same gaming and efficiency uplifts as this one then they're going to make more sense to a PC gamer. The 7900X3D has the same asymmetrical chiplet layout, so has the same compromises for productivity, but the 7800X3D is a pure 3D V-Cache gaming beast. If you ain't rendering in Blender, that's likely to be the best of the bunch for you. The Ryzen 9 7950X3D is going to be the most powerful Zen 4 CPU available, and is slated to go head-to-head with the Intel 13th Gen flagships. Its performance speaks for itself, however the only issue you might face is the price. If we're talking about this being AMD's take on the perfect gaming processor, we need to step outside of the 1080p gaming environment. We traditionally test at this lower resolution for our CPU game benchmarking so we are able to highlight the difference in performance down to the actual processors. As you go higher in the resolution scale you end up relying ever more on the power of the graphics card, to the point where you cease being able to discern meaningful performance deltas between chip architectures.
Many will draw parallels between AMD’s approach and Intel’s Thread Director, the latter of which steers threads to either high-performance or efficiency cores in the company’s x86 hybrid CPUs. The two mechanisms have plenty of similarities, but as you would expect, each company has a unique implementation with different goals. Having the on-chip integrated graphics present is highly useful for troubleshooting and, if you aren’t going to run games, it can save you from having to buy a display adapter, which cuts costs. The IGP that AMD opted to use on its processors, however, is relatively weak. The last-gen Ryzen 7 5700G has the fastest IGP of any desktop CPU, and while we don’t necessarily need that much performance in every desktop CPU, it’s too bad AMD opted for as weak an IGP as it did. The fact performance of X3D CPU is all over the place bothers me too. Yes it's fast in -some- games, but then you get less overall performance in several important applications. If I just used my PC for gaming, I would have bought a console, I don't like the idea of having to make a trade-off with X3D CPU. Starting with the Ryzen 7000 series, AMD began adding low-power IGPs to all of its Ryzen desktop processors. (Before, it was limited to the subset known as the G-series.) But this has been a bittersweet change since its introduction. It's simply the best gaming CPU by performance you can buy on the consumer market and that's not likely to change for the rest of this processor generation, at the very least.
