AMD Ryzen 9 3900X & Ryzen 7 3700X ‘Zen 2’ CPU Review

We will be outlining the Ryzen 3000 CPUs’ performance while using ASRock X570 Taichi and Gigabyte X570 Aorus Master Socket AM4 X570 motherboards. A 16GB (2x8GB) kit of 3200MHz CL14 DDR4 memory serves our test system.

Today’s comparison processors come in the form of:

  • Skylake-X i9-7920X (12C24T).
  • Coffee Lake i7-9700K (8C9T) and i9-9900K (8C16T).
  • Pinnacle Ridge Ryzen 7 2700X (8C16T) and Ryzen 5 2600X (6C12T).
  • Summit Ridge Ryzen 7 1800X (8C16T).

Each processor is tested at its default out-of-the-box settings. We also include reasonable overclocking performance data where relevant. For the Intel Coffee Lake 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 i9-9900K and i7-9700K. All-core load frequencies for the tested chips are as follows:

  • Ryzen 9 3900X = 3.975-4.1GHz.
  • Ryzen 7 3700X = 3.95-4.1GHz.
  • Core i9-7920X = 3.8GHz (most of the time, with AVX workloads or synthetic stress tests dropping to 3.4GHz and below).
  • Core i9-9900K = 4.7GHz.
  • Core i7-9700K = 4.6GHz.
  • Ryzen 7 2700X = Around 3.95GHz.
  • Ryzen 5 2600X = Around 3.975-4.0GHz.
  • Ryzen 7 1800X = 3.65GHz.
