Key Differences
-
The RTX 4070 Super has 64% more theoretical FP32 compute
The spread here is large: 35.5 TFLOPS on the RTX 4070 Super versus 21.7 TFLOPS on the RTX 3070 Ti. Expect to notice it. Architectures use their compute differently, so treat the gap as a guide and look at game benchmarks for the details.
-
The RTX 4070 Super has 4 GB more VRAM
Of all the specs we compared, this is one where the RTX 4070 Super makes its strongest case: 12 GB against 8 GB. Newer games tend to ask for more video memory, so the RTX 4070 Super’s extra VRAM helps the card age better.
-
The RTX 4070 Super has 70 W lower board power
The RTX 4070 Super clearly leads on total board power, and 220 W versus 290 W is a difference that reaches well beyond the spec sheet. The RTX 4070 Super draws less power, which makes it easier to cool in compact cases.
-
The RTX 4070 Super has 17% more shader units
On shader units, the RTX 4070 Super posts 7,168 against 6,144 for the RTX 3070 Ti, a gap big enough to feel in everyday use. Treat shader count as a strong hint about performance tier, then check benchmarks for the games you actually play.
-
The RTX 3070 Ti has 21% more memory bandwidth
This is one of the widest gaps in the whole comparison: 608 GB/s for the RTX 3070 Ti versus 504 GB/s for the RTX 4070 Super. Bandwidth needs vary by architecture, so compare it alongside VRAM and cache rather than on its own.
Design & Size
- RTX 3070 Ti 10.63 in × 2 slots
- RTX 4070 Super 9.61 in × 2 slots
Physically, these two aren’t the same size: the RTX 3070 Ti is larger in overall dimensions.
Size & Connectivity
| Spec | RTX 3070 Ti | RTX 4070 Super |
|---|---|---|
| Reference card length | 10.63 in | 9.61 in |

GPU & Performance
RTX 4070 Super leads
Few areas are as clear-cut as this one: the RTX 4070 Super leads the gpu & performance section with room to spare. The RTX 4070 Super stands out with 64% more theoretical FP32 compute. FP32 compute is a theoretical peak that combines shader count and clock speed, a quick way to size up raw power. So if gpu & performance tops your list, lean toward the RTX 4070 Super.
FP32 compute
RTX 3070 Ti: 21.7 TFLOPS RTX 4070 Super: 35.5 TFLOPS The RTX 4070 Super has more theoretical compute, which often, but not always, translates into higher frame rates.
Shader units
RTX 3070 Ti: 6,144 RTX 4070 Super: 7,168 Shader units do most of the heavy lifting in games, so more of them usually means more frames per second within the same architecture.
Memory
Trade-off
Here the two take different paths. The RTX 3070 Ti goes for 21% more memory bandwidth, the RTX 4070 Super for 4 GB more VRAM. If you’re torn on memory, the other sections may help break the tie.
VRAM
RTX 3070 Ti: 8 GB RTX 4070 Super: 12 GB At high resolutions or with texture packs, running out of VRAM can hurt more than a small speed gap.
Memory bandwidth
RTX 3070 Ti: 608 GB/s RTX 4070 Super: 504 GB/s Memory bandwidth decides how quickly the GPU can feed itself with data, which matters most at 1440p and 4K.

Power & Thermals
RTX 4070 Super leads
For power & thermals, the verdict is easy: the RTX 4070 Super leads, and not by a little. The RTX 4070 Super steps ahead thanks to 70 W lower board power. Higher board power often comes with higher performance, so the RTX 3070 Ti’s appetite may be part of the price of its speed. If this section decides it for you, choose the RTX 4070 Super.
Total board power
RTX 3070 Ti: 290 W RTX 4070 Super: 220 W Lower board power means less heat, quieter cooling and a smaller impact on your electricity bill.
Recommended PSU
RTX 3070 Ti: 750 W RTX 4070 Super: 650 W Recommendations include a safety margin for the rest of the system, so they’re a guide rather than a hard limit.
