Performance is in line with expectations of a 120W part, though there’s no escaping the fact regular 170W 7950X is the superior chip for demanding multi-threaded work. 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. The more cache a processor has, the fewer trips to RAM it needs to make for data or instructions, which greatly improves performance for many common tasks. Generally, more cache is better, and the 7950X3D has more cache than any consumer processor available today. No surprises in the memory department. The regular AIDA test doesn’t readily differentiate between CCDs so we can’t calculate the extra latency of hopping on over to X3D. Looking into further games reveals 7950X3D doesn’t have the benchmark wow factor of 5800X3D. That’s because Intel’s latest Raptor Lake architecture has moved the gaming needle to the right, limiting X3D’s comparative gains. 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.

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.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 cores, and by extension operating system, are oblivious to the bonding of extra L3. X3D appears and largely performs like a triple-dense L3 monster. We say largely as there is a minor overhead of four cycles in accessing the upper cache, but that’s a pretty good return all things considered. 3D V-Cache as implemented on Zen 3, which is the same as Zen 4 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. 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.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. 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. This graph is helpful in pushing up efficiency; do recall 7950X3D ships with a 120W TDP. Like 7950X regular, we believe AMD ought to have let it run mostly free of wattage constraints – a 170W TDP 7950X3D would certainly benchmark that little bit better… but then what would be the point of 7950X regular? Decisions, decisions. 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).

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.This asymmetrical L3 layout has consequences for dual-CCD chips such as the Ryzen 9 7950X3D and 7900X3D. Putting the right workload on the right CCD is one extra complication of the design. In practise, users want a seamless method of putting cache-heavy workloads – gaming being a prime example – on the 96MB L3 cache-infused CCD and small-footprint code on the regular CCD. It so happens AMD has an answer for this. Great multi-thread performance meets a very acceptable TDP. Result is a high placing on this graph which divides the multi-core Cinebench score by system-wide power consumption. 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.

In short, this makes the Ryzen 9 7950X3D not particularly competitive against any of Intel’s competing processors either. In almost every test, the Core i9-13900K is simply faster while also costing less. Gaming Tests Hefty performance requires ample cooling. The more advanced your chosen processor is, the higher the TDP will be. TDP stands for ‘Thermal Design Power’ and refers to the maximum amount of heat generated. AMD designed the Ryzen 9 7950X3D based on its Zen 4 microarchitecture, which I went over in greater detail in my review of the Ryzen 9 7950X, linked above. 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.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. The first part is a 3D V-Cache performance optimiser driver that’s included in chipset software 5.01.03.005 or newer. According to AMD, ‘the driver evaluates the performance in real time and dynamically modifies the preferred cores seen by Windows based on workload preference for the 3D V-Cache CCX or the standard die.’ Run automatically for best performance, behaviour can be overridden by the user for manual tinkering. 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. Another solid set of results. Zen 4 has previously shown good aptitude when running at lower wattages; 7950X3D carries on the good work.
