What reviewers say

Reviewers praise strong application performance but find cheaper Threadripper alternatives better value. PCTuning favours its balance of gaming and workstation performance and found useful overclocking headroom; CHIP is less persuaded, with the cheaper 1950X ahead in almost all of its benchmarks. Cooling and platform costs remain considerations.

Cores and clocks

Cores: 12
Threads: 24
Base clock: 2.9 GHz
Boost clock: 4.4 GHz
L3 cache: 16.5 MB
Cores: Skylake-X; 12 cores with Hyper-Threading. The unlocked multiplier is confirmed by Intel’s exact-model family product brief.
Clocks: Turbo Boost Max 3.0 up to 4.40 GHz on the preferred core; ordinary Turbo Boost 2.0 up to 4.30 GHz. The main boost field uses Intel’s highest published frequency. Intel planned availability on 28 August 2017, but contemporary Tom’s Hardware reporting says retail availability followed roughly a week later. September precision reflects that actual-sale evidence rather than the earlier promised date; an exact first-sale day remains unverified.
Cache: 16.5 MB Intel Smart Cache (L3).
