AMD Ryzen 9 3950X CPU Review

We will be outlining the AMD Ryzen 9 3950X CPU’s performance while using Gigabyte X570 Aorus Master motherboard. A 16GB (2x8GB) kit of 3200MHz CL14 DDR4 memory serves our test system.

Today’s comparison processors come in the form of:

  • Coffee Lake Core i7-9700K (8C8T), Core i9-9900K (8C16T), and Core i9-9900KS (8C16T).
  • Skylake-X Core i9-9960X (16C32T) and Core i9-9980XE (18C36T).
  • Matisse ‘Zen 2’ Ryzen 9 3900X (12C24T) and Ryzen 7 3700X (8C16T).
  • Zen+ Ryzen Threadripper 2950X (16C32T).

Each processor is tested at its default out-of-the-box settings. We also include reasonable overclocking performance data where relevant. For the Intel CPUs, forced turbo is enabled by default when XMP is enabled and, in most scenarios, cannot be disabled. As such, we test using the forced turbo frequencies with the Intel processors. All-core load frequencies for the tested chips are as follows:

  • Core i9-9900KS = 5.0GHz.
  • Core i9-9900K = 4.7GHz.
  • Core i9-9980XE = 3.8GHz (without AVX2/AVX-512 reductions).
  • Core i9-9960X = 4.0GHz (without AVX2/AVX-512 reductions).
  • Ryzen Threadripper 2950X = Around 3550-3600MHz.
  • Ryzen 9 3900X = Around 4050MHz (F7b BIOS, AGESA
  • Ryzen 7 3700X = Around 4050MHz (F7b BIOS, AGESA
  • Ryzen 9 3950X = Around 3800-3950MHz (F10a BIOS, AGESA
