Fragz' verdict
The RTX 4070 SUPER is the undeniable victor in this comparison, boasting a staggering 1748.2% lead in GPU score over the MX450. This massive performance gap is evident across all our tests; for instance, it delivers 44.5 FPS in Earth II Vulkan compared to the MX450's 3.5 FPS, making the difference between playable and unplayable gaming experiences. The RTX 4070 SUPER also vastly outperforms with 12 GB of VRAM versus 2 GB, a memory bandwidth of 149 GB/s versus 18 GB/s, a significantly higher ALU index, and a peak clock of 2940 MHz. Furthermore, it supports modern features like ray tracing and mesh shaders, which the MX450 lacks. While the MX450's data is based on only one verified run, its low GPU score and rank of 62 out of 67 clearly show it's not designed for serious gaming, making the RTX 4070 SUPER the only choice for performance.

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
