Fragz' verdict
The Radeon RX 7900 XTX absolutely demolishes the Radeon 680M in this showdown, delivering a staggering 2095.4% higher GPU score, though it's worth noting that both cards have very few verified runs in our data. This massive performance gap translates directly into a night-and-day gaming experience, with the RX 7900 XTX pushing over 100 FPS in Mission to Earth II (DX12) and nearly 90 FPS in Earth II Landing (DX12 Ultimate), while the 680M struggles to even hit 5 FPS in those same tests. The raw power difference is undeniable: the RX 7900 XTX boasts an ALU index of 803269, alongside a hefty 24 GB of VRAM and 122 GB/s bandwidth, compared to the 680M's mere 36353 ALU index, 2 GB VRAM, and 8 GB/s bandwidth. For serious gaming, the Radeon RX 7900 XTX is in a league of its own, making the Radeon 680M only a viable option when a high-performance dedicated GPU is simply not on the table.

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
