AMD Ryzen 9 3950X CPU Review

Application & Synthetic Testing

Sandra Memory Bandwidth

Note: All systems were run in dual channel or quad-channel modes where applicable. The Intel Core i9 10980XE used timings of 18,19,19,39@1T. The Intel 9900K used timings of 16,18,18,36@1T while the AMD test systems used timings of 16,16,16,36@1T.

In this test, we see a result of 31.72GB/s. At DDR4 3600MHz speeds, we saw a result of 34.93GB/s. This comes in a bit lower than some of the results we’ve seen from the Ryzen 3000 series in the past. I can generally attribute this to some AGESA code changes or manufacturer BIOS updates.

In this test, we see a CPU score of 755 GIPS at stock speeds and 799 GIPS when overclocked manually. This is a solid result and comes within a stone’s throw of the much more expensive Core i9 10980XE. This is also a CPU that has two more cores and is all the more impressive considering that fact.

Here we see results that again come close to the much more expensive Core i9 10980XE. We also see a small improvement over the Ryzen 9 3900X as well.

In this test, we actually see the Ryzen 9 3950X falter quite a bit. This likely comes down to differences in clocks. The base clocks are lower on the 3950X, so that may account for this.

The theory that clock speed matters here is both sort of upheld and sort of discredited. On one hand, the 9900K doesn’t beat everything, but the Core i9 10980XE does. The Ryzen 9 3950X scores are better than everything but the Core i9 10980XE. I have no idea on this one but this is a test that often produces odd results.

This is another weird one where we see the 3900X outpace the 3950X. The Core i9 9900K isn’t too far off the 3900X’s heals either. BIOS differences or other factors could be at play here, but it’s hard to tell what those might be.


In this test, the 3950X achieves an outstanding result that’s once again nearly as good as the much more expensive and highly overclocked Core i9 10980XE. Intel’s Core i9 9900K absolutely gets shamed here. We also see nice gains over the 12 core and 24 thread Ryzen 9 3900X.
