RTX 4070 Super vs RX 7800 XT — Which to Buy
| Spec | RTX 4070 Super | RX 7800 XT |
|---|---|---|
| VRAM | 12GB GDDR6X | 16GB GDDR6 |
| TDP | 220W | 263W |
| Memory Bandwidth | 504 GB/s | 576 GB/s |
| Upscaling | DLSS 3 and Frame Generation | FSR 3 |
The biggest spec differences: the RX 7800 XT has 16GB VRAM versus 12GB — a difference starting to matter at 1440p maximum settings. The RTX 4070 Super draws 43 fewer watts, which is a meaningful thermal advantage in a warm room or compact case.
Performance at 1440p
At 1440p both cards trade wins depending on the title. The RTX 4070 Super leads by 5 to 10 percent in raw rasterization most of the time. Where NVIDIA pulls ahead dramatically is DLSS 3 Frame Generation — in supported titles the perceived frame rate advantage can be 50 to 100 percent.
The Verdict
Check current prices. Within $30 of each other, buy the RTX 4070 Super for DLSS 3 and better thermals. RX 7800 XT is $40 or more cheaper, buy the RX 7800 XT for the VRAM advantage and better rasterization value.
