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 | AMD - Radeon RX 9070 |
|---|---|---|
| VRAM | 12 GB | 16 GB |
| Memory bus | 192 bit | 256 bit |
| TDP | 245 W | 220 W |

| CUDA / Stream cores | 3456 | 3584 |
| Ray tracing cores | 54 | 56 |
Between the Radeon RX 7700 XT and Radeon RX 9070, the Radeon RX 7700 XT comes out ahead in boost clock, while the Radeon RX 9070 wins on vram / memory bus. Overall, the Radeon RX 7700 XT scores 61.6 and the Radeon RX 9070 scores 64.9 on our Mars Score.
Which should you buy?
The Radeon RX 9070 edges ahead on the Mars Score (61.6 vs 64.9), but the 3.3-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Radeon RX 7700 XT if you care most about boost clock. The biggest gaps in its favor are boost clock. The single most decisive one: Boost clock — 0.95% more. 2544 MHz vs 2520 MHz.
Pick the Radeon RX 9070 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, tdp, among others. The single most decisive one: VRAM — 33.33% more. 16 GB vs 12 GB.
Both ship with comparable dlss, so those specs do not separate the two — focus on the differences below.
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: AMD - Radeon RX 7700 XT or AMD - Radeon RX 9070?
AMD - Radeon RX 9070 leads the current Mars Score by 3.3 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.
