Fragz' verdict
The RTX 5090 absolutely dominates this comparison, leading the NVIDIA RTX A3000 Laptop GPU by an incredible 1011.6% in GPU score, though the A3000's single verified run means its numbers should be taken with a grain of salt. This massive lead translates directly into gaming performance, with the RTX 5090 hitting 132.8 FPS in Earth II Vulkan, 171.4 FPS in Mission to Earth II DX12, and 113 FPS in Earth II Landing DX12 Ultimate, far outperforming the A3000's 11.2 FPS, 13.8 FPS, and 11.4 FPS respectively. Under the hood, the RTX 5090 boasts a significantly higher raw compute with an ALU index of 1020560 compared to 93658, much greater memory bandwidth at 660 GB/s versus 90 GB/s, a substantial 31 GB of VRAM, and a higher peak clock of 3112 MHz. For gamers, this means the RTX 5090 offers an unparalleled experience for demanding titles, delivering vastly higher frame rates and the horsepower needed for the most intensive graphical settings. However, the NVIDIA RTX A3000 Laptop GPU still has its place; its design likely targets portability, making it a suitable choice for mobile workstations or gaming on the go where the RTX 5090 would simply not fit.

What the numbers mean
The GPU score is the graphics card's own performance — that is what we rank on. GAMING is the whole rig's score in the best PC we measured the card in, and depends on processor, memory and storage. 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
