Key Differences
-
The RX 9070 XT has 4 GB more VRAM
Put simply, the RX 9070 XT is far ahead here: 16 GB compared with 12 GB. Newer games tend to ask for more video memory, so the RX 9070 XT’s extra VRAM helps the card age better.
-
The RTX 4070 Super has 84 W lower board power
The RTX 4070 Super’s 220 W leaves the RX 9070 XT’s 304 W well behind, so if this spec matters to you, the choice is easy. The RTX 4070 Super draws less power, which makes it easier to cool in compact cases.
-
The RX 9070 XT has 27% more memory bandwidth
Not a close call. The RX 9070 XT lists 640 GB/s and the RTX 4070 Super lists 504 GB/s. That’s a substantial gap. The RX 9070 XT has more bandwidth to work with, helping it hold up in memory-heavy games.
-
The RX 9070 XT has a wider 256-bit memory bus
Among all the differences on this page, 256-bit against 192-bit is one of the most meaningful, and it favors the RX 9070 XT. The RX 9070 XT’s wider bus supports higher bandwidth, which helps most at high resolutions.
-
The RTX 4070 Super has a smaller 650 W PSU requirement
The RX 9070 XT gives up a lot on recommended psu: 750 W, compared with 650 W on the RTX 4070 Super. With the RTX 4070 Super, you’re more likely to keep your existing power supply, which can save real money.

GPU & Performance
On gpu & performance, the useful details are the names in the table: what each one uses, not a figure we can rank.
Memory
RX 9070 XT leads
The memory numbers point firmly in one direction: toward the RX 9070 XT. The RX 9070 XT scores with 4 GB more VRAM. More VRAM lets the card hold higher-resolution textures and bigger scenes without stutter. Anyone shopping mainly on memory should start with the RX 9070 XT.
VRAM
RX 9070 XT: 16 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
RX 9070 XT: 640 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
When it comes to power & thermals, the RTX 4070 Super is comfortably ahead. The RTX 4070 Super takes this one with 84 W lower board power. Higher board power often comes with higher performance, so the RX 9070 XT’s appetite may be part of the price of its speed. Bottom line for power & thermals: the RTX 4070 Super has the edge.
Total board power
RX 9070 XT: 304 W RTX 4070 Super: 220 W Lower board power means less heat, quieter cooling and a smaller impact on your electricity bill.
Recommended PSU
RX 9070 XT: 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.
