The $599 Ryzen 9 7900X3D leverages AMD's 3D V-Cache technology to deliver incredible gaming performance, but its unreasonably high pricing leaves it vulnerable to stiff competition from both higher- and lower-cost chips. As we've seen with the other 3D V-Cache-equipped chips, the 7900X3D also suffers from lower performance in productivity applications than its standard counterpart — in this case, the Ryzen 9 7900X, but that's harder to swallow with the higher price tag.
Below, we have the geometric mean of our gaming test suite at 1080p and 1440p and a cumulative measure of performance in single- and multi-threaded applications. We conducted our gaming tests with an Nvidia RTX 4090, so performance deltas will shrink with lesser cards and higher resolution and fidelity settings.
The first slides are simplified by excluding the overclocking configs, while the remainder contain the full roster of tested configurations. These are cumulative measurements, though, and the 3D V-Cache doesn’t accelerate all titles equally — you’ll need to check our individual game benchmarks on the preceding pages to make an informed decision based on your workload.
The $699 Ryzen 9 7950X3D is ~7% faster than the $589 Core i9-13900K in 1080p gaming at stock and overclocked settings, and it beats the much less expensive $409 Core i7-13700K by 9%. However, these chips offer superior performance in productivity applications, offsetting the gaming advantage for those seeking a more well-rounded solution. For similar pricing, the 13900K is 21% faster than the Ryzen 9 7900X3D in single-threaded work and 32% faster in threaded applications. You could also step down a pricing tier to the less expensive 13700K — it's 6% faster in multi-threaded and 12% faster in single-threaded than the 7900X3D.
The $699 16-core Ryzen 9 7950X3D is by far the 7900X3D's biggest competition — the flagship is 6% faster in gaming than the 12-core 7900X3D at stock settings and 4% faster after overclocking. However, it also comes with four additional cores that help reduce the shortcomings in productivity applications; the 7950X3D is 27% faster in threaded work and 4% faster in single-threaded applications.
There's a $100 price difference (15%) between the Ryzen 9 7950X3D and Ryzen 9 7900X3D, and given the high pricing of a leading-edge rig that will house this class of processor, most should step up to the 7950X3D. For instance, the extra $100 would add roughly 3% or less to the cost of a $3,000 to $4,000+ system suitable for this class of chip. Given the sizeable improvement in both gaming and application performance with the 7950X3D, most should spend that comparatively little extra cash to step up.
The Ryzen 9 7900X3D is incredibly power efficient, drawing far less power than either the standard 7900X or the competing Intel chips, thus delivering superb power efficiency that ranks among the best we’ve ever tested. That means you’ll ultimately benefit from a cooler, quieter system. The chip also drops into AM5 motherboards that support the latest connectivity tech, like PCIe 5.0 and DDR5, and AMD plans to support the platform until 2025+. In contrast, Intel’s current round of motherboards will only support one more generation of chips, so upgradeability remains an advantage for AMD.
Overall, AMD has done an outstanding job in bringing thermals under control well enough to deliver high core count chips with 3D-stacking tech that provides excellent performance within an acceptable TDP threshold. The driver implementation also works well to automatically optimize the system for different usages on the fly while also leaving plenty of room for end-user configuration.
However, much like we saw with the Ryzen 9 7900X, the 7900X3D's pricing is the fly in the ointment. It might also be why AMD didn't sample this chip to the press. Most dedicated gamers aren’t interested in a $599 processor for gaming only, and we certainly don't recommend spending this much if that's your only goal. Instead, you should wait for the eight-core $449 Ryzen 7 7800X3D that will likely offer nearly the same amount of gaming performance when it arrives in April.
Given that the Ryzen 9 7900X3D is designed to be really good at one thing, gaming, while accepting trade-offs in others, it has to excel in such a way that other options aren't worthy of consideration. The Ryzen 9 7900X3D doesn't quite meet that bar and has tremendous pressure from both lower- and higher-end Ryzen models, like the Ryzen 9 7950X3D, while also facing value competition from Intel's chips, leaving little room for success at its current pricing. We expect this chip to see big price reductions over the coming months, but until then, it's better to seek other alternatives.
