AMD Ryzen 9 7950X3D 3D V-Cache CPU Benchmarks Leak: 10% Slower In Multi-Thread & Similar Single-Core As 7950X

The first unofficial AMD Ryzen 9 7950X3D 3D V-Cache CPU benchmarks have leaked out within the Geekbench 5 database.

The AMD Ryzen 9 7950X3D is the flagship & the first 16-core CPU to feature 3D V-Cache technology. The chip will incorporate a total of 32 threads, a total of 144 MB cache (64 MB CCD, 64 MB V-Cache + 16 MB L2), and a TDP of 120W. As for the clocks, the chip is rated at a base clock of 4.2 GHz which is 300 MHz slower than the standard 7950X but boost clocks are rated at the same 5.7 GHz. This should give us a hint at why the TDP is 50W lower versus the Non-3D part.

The AMD Ryzen 9 7950X3D was tested on an ASUS ROG Crosshair X670E HERO motherboard with 32 GB of DDDR5 memory. It looks like Geekbench 5 is unable to read the exact L3 cache for Ryzen 3D V-Cache "Zen 4" chips at the moment. In terms of performance, the CPU scored 2157 points in the single-core and 21841 points in the multi-core tests.

The CPU ends up around 10% slower than the AMD Ryzen 9 7950X and Intel Core i9-13900K CPUs within the multi-core tests while offering similar single-core performance. The deficit in multi-core performance is to be expected considering the Ryzen 9 7950X3D doesn't has a lot of voltage or the thermal headroom to work with as the standard non-3D CPUs. The benchmark log shows that the chip maxed out around a peak 5.5 GHz boost clock which is slightly slower than the 5.7 GHz boosts that the 7950X non-3D can hit and explains the lower multi-core numbers.

Once again, the AMD Ryzen 9 7950X3D offering about 90% of the performance of the 7950X while delivering even faster gaming performance is going to be one insane deal for high-end users. The SiSoftware Sandra Arithmetic benchmark results are also posted below:

In addition to the Geekbench benchmark, there's also the performance of the chip within Blender where the chip scores 558.59 points which are around 5% slower than the 7950X.

AMD compared the Ryzen 9 7950X3D CPU to Intel's top Core i9-13900K across several gaming and workload apps. The results show that the 3D V-Cache chip can offer up to 24% faster performance in gaming at 1080p with high image quality. Following are the game tests and the respective gains over the 13900K CPU:

As we mentioned above, the 7950X3D chips have a different CCD configuration with one running at higher clocks and the other with conservative limits set in place due to the 3D V-Cache stacking. But that doesn't change the overall performance a lot even in workload apps as the chip can outclass a Core i9-13900K CPU in various tests as shown below:

The AMD Ryzen 9 7950X3D and the Ryzen 9 7900X3D are going to launch later this month on the 28th for prices of $699 US and $599 US, respectively.
