when all 16 cores and 32 threads are under load, but in practice we see it running at a higher speed of 4.

AMD Ryzen 9 7950X3D - Review 2023 - PCMag UK

Unlike the last-gen's Ryzen 7 5800X3D, the 7950X3D does allow for some narrow, controlled overclocking through AMD's Ryzen Master utility, but we're talking about presets rather than setting specific voltages, something you won't be able to do with this chip.The RAM is operated at the max officially supported RAM speed of the CPU, which is 5,200MHz for all Ryzen 7000-series CPUs.

AMD Ryzen 9 7950X3D review: Team Red retakes the lead with

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. This is a premium chip though, so it's as expensive as its non-3D sibling, but to its credit it doesn't make you pay more either. In most CPU tests, however, the cache is not that helpful, and this is what paints the worst picture of the Ryzen 9 7950X3D.One of these CCXs is a standard Zen 4 CCX that’s no different than you’d find on any other Zen 4 processor, whereas the other CCX, uniquely, contains the added cache. L3 bandwidth is again mixed but arguably better overall on AMD’s Ryzen 9 7950X than the Ryzen 9 7950X3D. A corresponding reduction in thermal design power (TDP) rating also occurred, with the Ryzen 9 7950X having a 170-watt (W) TDP and the Ryzen 9 7950X3D having a 120W TDP.

Cache is simply a very direct form of working memory that the processor keeps close by for instructions and data that it is using at that very moment. Other than the X3D designation on the spider-esque heatspreader, you cannot tell cache-enriched versions apart from regular AM5 chips. When it comes to the real-world performance of the 7950X3D, it will either hold its own against the other two flagship chips in tests like PCMark 10 or it will absolutely wallop its rivals thanks to its considerably bigger cache when gaming or encoding video. Instead of going over the Zen 4 nuances again (hit the review for more detail if desired), let’s focus on what’s unique with the Ryzen 9 7950X3D.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. In practice, this seems to work very well behind the scenes without any adjustments from the user beyond installing the upgraded drivers when you install the chip, but there still might be some optimizations that need to be worked out, especially when it comes to benchmark tests, but we'll get to that in a minute.
