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.

My PC runs every game that I play without issues. And with the recent GPU upgrade I'll be happy for another year or so and will upgrade when needed.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? The Xbox Game Bar contains a KGL (known good list) of games that it detects when active, thus triggering Game Mode (you can also instruct the game bar to recognize unknown games and/or other applications as games). The driver communicates with the Windows Game Mode feature, which becomes active when the Xbox Game Bar detects a game is running. 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! 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. The chipset drivers also install the AMD PPM Provisioning File Driver, which improves performance by parking the slowest cores when Game Mode or Mixed Reality Mode is active. In effect, this shuts down the ‘standard’ CCD when Game Mode or Mixed Reality Mode is active, thus constraining latency-sensitive workloads (like games) to the 3D V-Cache chiplet. This improves the cache hit rate and reduces high-latency communication between the two CCDs, resulting in faster performance for workloads that don’t need access to (or benefit from) all the cores.

In terms of power draw, the minimum I recorded for the 13900K is a meager 2.882W, and it could hover around this for hours if you're not using your computer thanks to its energy-efficient hybrid-core design. Meanwhile, the 7950X3D is still slurping up just over eight times as much power as a baseline. Finally, the last major difference is the lower TDP on the 7950X3D compared to the 7950X (120W to 125W). This is mostly from the lower frequency on the 3D V-Cache cores (as well as some other optimizations), meaning that the 7950X3D can use less power overall to get the same or better performance. When it comes to the Intel Core i9-13900K, it too outperforms the 7950X3D in single core performance, with the 7950X3D running about 12% slower than the 13900K on average. The difference between the two tightens on multicore performance, with the 7950X3D running about 5% slower in multicore on average. The lower power consumption measured during Adobe Premiere and Cinebench gives the Ryzen 9 7950X3D better overall performance per watt and slightly better overall energy efficiency. This is hurt by the high idle power consumption, however, which never drops below 97W with the system sitting idle at the desktop for prolonged periods. This latter issue may be resolved with a BIOS or driver update, though.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. 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. 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.

Cache has been an essential and highly influential part of computers for decades now, and its importance is unquestionable. What is questionable, however, and what has been questioned since the beginning, is how much cache is enough. Some argue that you can never have enough, but this is illogical. More cache means a larger, or in this case, an extra, chip—and that leads to higher costs. Past a certain point, it becomes questionable if the CPU will even be able to use or take advantage of all the cache you have. When it comes to the synthetic benchmarks, there's very little difference between the 7950X3D and the 7950X. Both chips are phenomenal multitaskers, and though the 7950X has consistently stronger single core scores than the 7950X3D, the 7950X3D performs better with multi core performance than its non-3D V-Cache counterpart. AMD’s Collaborative Processor Performance Control (CPPC2) interface already ranks the fastest cores as the highest priority, enabling the OS to schedule threads into these ‘preferred’ cores first. Not all Ryzen cores can reach the rated peak frequency, so this tech is critical to ensure strong performance in lightly threaded apps, like gaming.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.

What's also so notable about the 7950X3D is that while Intel's latest processors have been outstanding, that performance is far more a function of just throwing power at the problem, literally, than it is some kind of technological magic behind the scenes. There are some tradeoffs to attaining the leading gaming performance, though — some games don’t benefit from the 3D V-Cache, and the chip isn’t as fast in productivity apps as competing Intel chips. The 7950X3D also suffers from many of the pain points we’ve already seen with the fledgling AM5 platform — the motherboard ecosystem is more expensive than Intel’s offerings, and the strict requirement for DDR5 significantly increases costs compared to Intel’s DDR4-friendly platform. AMD’s decision to add extra cache to only one of these chips is somewhat unconventional, as the two CCXs will have different performance characteristics as a result, but there’s a logical reason behind it. The added cache chip and its position on top of one of the CCXs introduce power and heat considerations to the CPU that didn’t exist before. 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. Quite simply, AMD does so much more with far less power than either of the competing flagship processors, and you don't have to accept lower performance as a tradeoff. Much more often than not, you're getting a substantially faster processor in practice — especially for gaming — making it very hard to deny the AMD Ryzen 9 7950X3D its due.AMD's X670E, X670, B650E and B650 motherboards all support Ryzen 7000 out of the box. X670E offers PCIe 5.0 throughout, X670 offers PCIe 5.0 for storage and graphics, and B650 offers PCIe 5.0 for storage only. In general, as you progress from X670E to B650, expect fewer features, fewer PCIe lanes and lower prices - although no doubt we'll see cheaper X670E and premium B650 boards that will blur the lines between the four different chipsets. X670 and X670E debut in September, while B650 and B650E arrive in October. Anandtech has a great article that goes more into depth on the differences between the various chipsets. What memory is best for Ryzen 7000? 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. 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.] 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.
