Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | AMD - Radeon RX 7700 XT | NVIDIA - GeForce RTX 5090 |
|---|---|---|
| CUDA / Stream cores | 3456 | 21760 |
| TDP | 245 W | 575 W |
| Ray tracing cores | 54 | 170 |
| VRAM | 12 GB | 32 GB |
| Memory bus | 192 bit | 512 bit |
| 3DMark Time Spy | 14800 | 32500 |
Between the Radeon RX 7700 XT and GeForce RTX 5090, the Radeon RX 7700 XT comes out ahead in tdp / boost clock, while the GeForce RTX 5090 wins on cuda / stream cores / ray tracing cores. Overall, the Radeon RX 7700 XT scores 61.6 and the GeForce RTX 5090 scores 84.2 on our Mars Score.
Which should you buy?
The GeForce RTX 5090 is the clear pick on raw spec strength, leading by 22.6 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
Pick the Radeon RX 7700 XT if you care most about tdp / boost clock. The biggest gaps in its favor are tdp, boost clock. The single most decisive one: TDP — 330.00 W less. 245 vs 575.
Pick the GeForce RTX 5090 if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. Its strongest claims are cuda / stream cores, ray tracing cores, vram, among others. The single most decisive one: CUDA / Stream cores — 529.63% more. 21760 vs 3456.
There are no meaningful ties on the headline specs — every popular-comparison metric has a winner.
Bottom line: the GeForce RTX 5090 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
Which should you buy: AMD - Radeon RX 7700 XT or NVIDIA - GeForce RTX 5090?
NVIDIA - GeForce RTX 5090 leads the current Mars Score by 22.6 points.The more useful decision is the trade-off behind that result: compare vram, cuda / stream cores, boost clock, tdp against the way you will actually use the product.
