If you want the best performance, do not use process lasso. People will advise using it, but when I tested Process Lasso in games, I saw lower performance compared to when I just used game bar to automatically handle CCD assignment. If you want the easier option, use game bar it's less hassle in the long run. If you decide to follow my advice, all you need to do is the following and everything should work as intended. 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. Update Windows game bar via the Windows Store. It usually needs to be updated twice, same for all MS Store apps so restart the MS Store mid way through and update again. John (He/Him) is the Components Editor here at TechRadar and he is also a programmer, gamer, activist, and Brooklyn College alum currently living in Brooklyn, NY. To be clear (and contrary to our earlier theorizing that we mentioned in the Editors' Note up top), the Ryzen 9 7950X3D's IGP doesn't have access to the L3 cache on the processors, but just like the 3D V-Cache can help gaming performance with a graphics card, it can help the IGP perform better in the right scenarios, too. If the IGP did have access to the L3 cache, we would expect to see an even more pronounced performance boost, and the idea of seeing a future Ryzen 7000-series APU, a processor with a relatively powerful IGP and the 3D V-Cache together, would be exciting. That's not what this is, though. System Power and Thermals
With both tuned, I'd still rather have the 16 core variant personally. It'll be the better overall chip IMO, basing this off the 7950X vs the 7700X. Just let the "platform cost" argument go, otherwise test Intel with DDR4 and make proper comparisons showing what you get going with older and slower technology.Especially considering that Intel's 13th gen would take a massive performance plunge if paired with DDR4. AMD’s new thread management technique requires Windows 10 (1903) or 11 (21H2) and four components — a new chipset driver, updated BIOS, Windows Game Mode, and an updated version of the Xbox Game Bar (you can update through the Microsoft Apps store). 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.I am just trying to get core parking working on an existing Windows 10 install which is proving to be a challenge. Followed all the guides and everything is installed but it’s currently refusing to park. Just updating Windows 10 and I’m hoping this will be the fix. I have associated resource monitor to Game Bar to see if it will park to test. Are there any other options? 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.
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. 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. You also really can't discount the performance-per-watt that you're getting with the Ryzen 9 7950X3D, which is at least twice what you'd get with the Intel Core i9-13900K and about 55% better than the 7950X. Given that the game bar has no idea what a game is and needs a list it may well be that it needs a second list of programs to be prioritised on the regular CCD.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. 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. Stress testing tools like Cinebench R23 push the processor to its engineered limits in terms of power use and operating temperature, and I use these to make sure that every chip is pushed to full 100% CPU utilization under load to determine the minimum and maximum amount of power the processor uses (measured in watts) and the minimum and maximum temperature recorded (measured in Celsius). 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? 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.
PlaneInTheSky said: My PC from 14 years ago still browses the internet just fine. It still does Spotify, Netflix, indie gaming, etc.I noted that Paul mentioned AMD's specification to use water-cooling on the X3D lineup. After noting the low power usage of these chips I am curious as to why. Has the chip been tested using a more typical air cooled tower fan (with both standard, PBO, and PBO-UV) to determine if water-cooling is even necessary? Setting CPPC to driver is not really necessary. In theory it should still work, but just use Auto for now since you are overriding the default behaviour which I know works. I’ve tested something like 30+ games in my Steam, Battle.net, Origin, GOG, Ms-Store, Ubisoft and everything was recognised and worked without issue. We do not charge you a fee for our services.

Perform a clean installation of Windows. Things will work better rather than using an old OS that was used for a different CPU. This bit is important, so don't overlook it, otherwise you might need to use something like Process Lasso. I recommend the latest Windows 11 22H2 build, which I use with my 7950X3D. I've tested Windows 10 vs 11, and 11 is clearly faster in gaming so if you are on 10 take this into consideration. 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.When trying to come to an overall assessment of these chips' relative performance, it's better to look at the measurable performance gains between chips across different tests. This makes for a much more sensible average when all is said and done than averaging absolute scores where one CPU test with one very large result can badly skew a final average.
