Fragz' verdict
Alright, gamers, straight up: the Ryzen 7 5800X absolutely crushes the Ryzen 5 5500U with Radeon Graphics, leading by a massive 275% in CPU score. This beast brings significantly higher single-thread performance at 0.62 Gop/s compared to the 5500U's 0.19 Gop/s, alongside a boost in multi-threaded integer performance and over three times the draw calls per second, all thanks to its higher peak clock, more cores, and larger L3 cache. What does that mean for you? Far smoother gameplay, higher FPS ceilings in games, and a much better experience in titles that demand a lot from the CPU, as seen with its 66.8 Supernova DX11 FPS versus the 5500U's 22.8 FPS. While the Ryzen 5 5500U only has one verified run, making its sample thin, its lower specs clearly point to a different class of hardware, likely for systems where gaming isn't the primary focus.

What the numbers mean
The CPU score is the processor's own performance — that is what we rank on. GAMING is the whole rig's score in the best PC we measured the processor in, and leans heavily on the graphics card. A strong processor in a weak PC gets a low GAMING score without being worse. We show both and never mix them.
All numbers come from our benchmark suite: four hand-built 3D scenes written directly against the graphics APIs in Rust, the same load on every PC. The methodology is open at https://whatfps.com/metodik
