AMD Ryzen 7 5800U Review
The AMD Ryzen 7 5800U is an 8-core, 16-thread ultraportable processor built on genuine Zen 3 (Cezanne), running a 1.9 GHz base clock that boosts to 4.4 GHz within a 15 Watt TDP.
This is the Zen 3 counterpart to the Zen 2-based 5700U within AMD's mixed Ryzen 5000 U-series lineup, delivering meaningfully better single-thread performance thanks to the newer core architecture at the same power envelope.
AMD Radeon Vega 8 Graphics
An 8-compute-unit Vega iGPU, adequate for everyday productivity and light gaming at reduced settings.
How Is the Ryzen 7 5800U in Terms of Performance
Zen 3's architectural improvements give this chip genuinely stronger single-thread performance than the Zen 2-based 5700U at the same 8-core, 16-thread layout and power envelope, a real generational gain within the same U-series family.
Benchmarks
Cinebench R23 multi-core scores of 8,159 and single-core scores of 1,433 lead the Zen 2-based Ryzen 7 5700U's comparable figures, directly reflecting Zen 3's real per-core improvement. Geekbench 4.1 multi-core scores of 28,299 confirm this chip's standing among the strongest ultraportable chips of its generation.
