The AMD Ryzen 9 3950X Review: 16 Cores on 7nm with PCIe 4.0
by Dr. Ian Cutress on November 14, 2019 9:00 AM ESTGaming: F1 2018
Aside from keeping up-to-date on the Formula One world, F1 2017 added HDR support, which F1 2018 has maintained; otherwise, we should see any newer versions of Codemasters' EGO engine find its way into F1. Graphically demanding in its own right, F1 2018 keeps a useful racing-type graphics workload in our benchmarks.
We use the in-game benchmark, set to run on the Montreal track in the wet, driving as Lewis Hamilton from last place on the grid. Data is taken over a one-lap race.
All of our benchmark results can also be found in our benchmark engine, Bench.

For Brownian motion? That seems weird. Nonetheless, it can't alone explain the speed up.Most favourable scenario: code consists only of floating point mul and add pairs, together with 64-bit integer multiplication. The floating point operations could become 4x faster in AVX2 (twice as wide as SSE, and using FMAs); to see the observed 2x speed up, that means the floating point operations constituted 2/3 of the execution time in the SSE version.
The AVX512 version, ignoring any consequent downclocking, could make those floating point operations 8x faster than the SSE case, and the 64-bit integer multiplies also 8x faster. That's still not 10x, it ignores the lower throughput of 8-wide i64 muls compared to scalar muls, and also discounts the slower clock speed.

Just an update: ran a simple test (square eight times all the 64-bit ints in a 1024-long array) wrapped in google benchmark on a Skylake Xeon with gcc-8.2 -O3. The kernel is almost entirely multiplications, and ultimately saw a roughly 2x speed up with AVX512 compared to AVX2, and a 2.5x speed up with AVX512 compared with a 'no architecture specified' compilation.w1p30ut3r - Friday, November 22, 2019 - link
Its very, very simples. If you gaming lonly buy an intel... If you work and gaming buy a 3950x... If you only work buy a threadripper or a xeon...Parkab0y - Sunday, October 4, 2020 - link
