Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | NVIDIA - GeForce RTX 5070 | AMD - Radeon RX 7800 XT |
|---|---|---|
| CUDA / Stream cores | 6144 | 3840 |
| VRAM | 12 GB | 16 GB |
| Memory bus | 192 bit | 256 bit |
| Ray tracing cores | 48 | 60 |
| TDP | 250 W | 263 W |
| Boost clock | 2512 MHz | 2430 MHz |
Between the GeForce RTX 5070 and Radeon RX 7800 XT, the GeForce RTX 5070 comes out ahead in cuda / stream cores / tdp, while the Radeon RX 7800 XT wins on vram / memory bus. Overall, the GeForce RTX 5070 scores 63.9 and the Radeon RX 7800 XT scores 63.9 on our Mars Score.
Which should you buy?
These two are evenly matched on the broad strokes; the decision sits on which individual spec advantages weigh more for your use.
Pick the GeForce RTX 5070 if you care most about cuda / stream cores / tdp. The biggest gaps in its favor are cuda / stream cores, tdp, boost clock, among others. The single most decisive one: CUDA / Stream cores — 60.00% more. 6144 vs 3840.
Pick the Radeon RX 7800 XT 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 vram, memory bus, ray tracing cores. The single most decisive one: VRAM — 33.33% more. 16 GB vs 12 GB.
There are no meaningful ties on the headline specs — every popular-comparison metric has a winner.
Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity says both are well-rounded; the differences are about trade-offs, not quality.
Which should you buy: NVIDIA - GeForce RTX 5070 or AMD - Radeon RX 7800 XT?
The two products are effectively tied on the current Mars Score.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.
