AMD Ryzen 7 3800XT Review
The AMD Ryzen 7 3800XT is an 8-core, 16-thread Zen 2 desktop processor, running a genuinely high 4.2 GHz base clock that boosts to 4.7 GHz, with a large 32MB L3 cache within a 105 Watt TDP on the AM4 socket.
As a late-cycle refresh of the Ryzen 7 3800X, this XT variant pushed clocks higher through refined manufacturing, giving buyers a genuine boost-clock improvement on the same core Zen 2 silicon.
Integrated Graphics
This chip ships without a functional integrated GPU; a discrete graphics card is required for display output.
How Is the Ryzen 7 3800XT in Terms of Performance
The 8-core, 16-thread layout with a genuinely high 4.2 GHz base clock gives this chip excellent gaming and productivity performance, representing AMD's refined-process push on late Zen 2 desktop silicon.
Benchmarks
Cinebench R20 single-core scores of 542 reflect genuinely excellent per-core performance, among the strongest of any Zen 2 desktop chip, directly reflecting the higher clocks this XT refresh reaches.
