AMD Threadripper 1950X Linux Benchmarks

Last week I was able to finally get my hands on a Threadripper 1950X system thanks to AMD for being able to deliver some Linux tests from this high-end desktop platform. The Threadripper 1950X as a reminder is a 16-core processor with 32 threads via SMT, 3.4GHz base frequency, 4.0GHz boost frequency, quad-channel DDR4 support, and support for 64 PCI-E lanes. Threadripper sits between the Ryzen 7 desktop processors and the AMD EPYC server/workstation processors, which are still soon to be tested at Phoronix. The Ryzen Threadripper 1950X will set you back $999 USD, but compared to the Core i9 7900X at the same price, has six more cores / 12 threads and a slightly higher base clock frequency of 3.4GHz vs. 3.3GHz but a lower boost frequency of 4.0GHz vs. 4.3GHz.

Some Early AMD Ryzen Threadripper 1950X Linux Benchmarks

Yesterday along with the completely Linux-trouble-free Ryzen 7 (it indeed went overnight without any issues coming up via the kill-ryzen script), I finally got my hands on the AMD Threadripper. In particular, the Ryzen Threadripper 1950X that features sixteen physical cores yielding 32 threads via SMT, 3.4GHz base frequency, 4.0GHz boost clock frequency, and quad-channel DDR4 support. This Threadripper 1950X is a beast but will set you back $999 USD and has a 180 Watt TDP. I'll have my much more thorough AMD Ryzen Threadripper 1950X Linux review next week including many more benchmarks, performance-per-dollar, and system power use / performance-per-Watt metrics, but here are some very early results for those anxious to see this HEDT PC on Linux.
