Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | Intel - Arc B770 | NVIDIA - GeForce RTX 4080 SUPER |
|---|---|---|
| CUDA / Stream cores | 4096 | 10240 |
| Ray tracing cores | 32 | 80 |
| TDP | 225 W | 320 W |
| 3DMark Time Spy | 13500 | 21500 |
| Boost clock | 2900 MHz | 2550 MHz |
| DLSS | false | true |
Between the Arc B770 and GeForce RTX 4080 SUPER, the Arc B770 comes out ahead in tdp / boost clock, while the GeForce RTX 4080 SUPER wins on cuda / stream cores / ray tracing cores. Overall, the Arc B770 scores 64.2 and the GeForce RTX 4080 SUPER scores 69.7 on our Mars Score.
Which should you buy?
The GeForce RTX 4080 SUPER edges ahead on the Mars Score (64.2 vs 69.7), but the 5.5-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Arc B770 if you care most about tdp / boost clock. The biggest gaps in its favor are tdp, boost clock. The single most decisive one: TDP — 95.00 W less. 225 vs 320.
Pick the GeForce RTX 4080 SUPER 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, 3dmark time spy, among others. The single most decisive one: CUDA / Stream cores — 150.00% more. 10240 vs 4096.
Both ship with comparable vram, memory bus, so those specs do not separate the two — focus on the differences below.
Bottom line: the GeForce RTX 4080 SUPER 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: Intel - Arc B770 or NVIDIA - GeForce RTX 4080 SUPER?
NVIDIA - GeForce RTX 4080 SUPER leads the current Mars Score by 5.5 points.The more useful decision is the trade-off behind that result: compare cuda / stream cores, boost clock, tdp against the way you will actually use the product.
