AMD Ryzen 7 7800X3D vs Ryzen 9 7950X3D: Is 7800X3D better than 7950X3D?

The Ryzen 7 7800X3D and Ryzen 9 7950X3D are similar except for one thing. In addition to the Zen 4 3D V-Cache die, it features a second CCD

The Ryzen 7000X3D processors are the best gaming processors on the market. With the Ryzen 7 7800X3D starting at <$400, the V-Cache chips are faster, affordable, and more power-efficient than their Intel rivals. The 7800X3D has been AMD’s bestselling CPU for a year now, with the Ryzen 9 7950X3D also earning its place. The 7900X3D is the middle child, offering a bit of this and a bit of that but enough of neither.

The Ryzen 7 7800X3D and Ryzen 9 7950X3D are similar except for one thing. In addition to the Zen 4 3D V-Cache die (rainbow marking) on the former, the latter features a second Zen 4 CCD (without the stacked cache). You’d think that’d make it the better CPU, but that’s not always the case.

Test Methodology

In gaming workloads, the CPU paints the outline of a scene, leaving instructions for the GPU about the various objects->meshes->polygons that need to be rendered. The GPU does the actual rendering, following the outline or blueprint left by the CPU. In general, the object detail is altered by increasing/decreasing the polygon or pixel count.

The polygons affect the actual appearance of the object, making it more or less detailed. The instructions for that are left by the CPU in the outline (known as draw calls). In-game, this is controlled by the terrain/mesh/geometry settings in the graphics menu.

The scene geometry has a direct impact on CPU performance. On the other hand, the resolution or pixel count is GPU-controlled as it affects how many samples are used to represent the 3D scene in rasterized form.

Therefore to gauge CPU performance, we limit the resolution to 720p (to remove GPU bottlenecks) and turn up the graphics settings to “Ultra.”

AMD Ryzen 7 7800X3D vs Ryzen 9 7950X3D: Ray Tracing Performance

Enabling ray tracing increases the load on the CPU and the GPU. The CPU issues the draw calls to initiate the BVH construction and the ray generation, while the GPU does the BVH testing, ray-tri/box testing and the eventual shading. This whole process is becoming more GPU-localized with every new generation of RTX GPUs.

Cyberpunk 2077

Cyberpunk 2077 runs even better on the Ryzen 9 7950X3D with ray-tracing, while the Ryzen 7 7800X3D suffers from relatively lower 1% percentile FPS. This is likely because this game can utilize up to 16 CPU cores or more. The frametimes look similar, except for that little stutter patch on the 7800X3D near the end of the test.

Thermals, Power Consumption, and Clocks

Here are some interesting numbers from the benchmarks of the two CPUs captured using CapFrameX in Cyberpunk 2077 and Dying Light 2:

Despite drawing 20% more power, the Ryzen 9 7950X3D has the same average package temperature as the 7800X3D. Furthermore, even though the 7800X3D is faster on average, the game spends more time CPU-bound than the 7950X3D.

Dying Light 2 exhibits similar characteristics. Even though the 7950X3D draws more power, its thermals are almost identical to the 7800X3D. It also results in fewer CPU-bound scenarios compared to the 7950X3D.

Regarding clock speeds, the Ryzen 9 7950X3D runs 100MHz faster than the Ryzen 7 7800X3D in both games. The boost clock of the V-Cache dies was considered in both cases.

Conclusion

The Ryzen 7 7800X3D is clearly the better gaming CPU. It’s faster, more affordable, and power efficient than the Ryzen 9 7950X3D. The reason why it’s faster is two-fold. The 3D V-Cache boosts gaming performance by localizing the game code to the large L3 cache, improving latency and reducing memory accesses.

With the 7950X3D, the OS sometimes assigns a thread to the cores on the second CCD. Since most of the game code is on the (larger) first CCD, this induces a latency penalty as the core accesses it across the interconnect bus.

The extra cores on the Ryzen 9 7950X3D are nice to have, but games are more sensitive to memory/cache bottlenecks. The 7800X3D, with its large, uniform 96MB L3 cache pool, keeps the needed game code close to the cores in one place. Luckily, if you have a 7950X3D, you can technically run it as a 7800X3D in gaming workloads by disabling the second CCD. Just make sure you disable the one with the lower L3 cache.
