Verdict
At $969.00, the RTX 4070 Super costs about 14% less than the $1,129.99 Radeon RX 7900 XTX. That $160.99 saving is real money, but not so wide that the pricier card is out of reach.
The Radeon RX 7900 XTX's 24 GB of VRAM is a 12 GB advantage over the RTX 4070 Super. At 4K or in heavily modded games that extra buffer matters — and it provides headroom as future titles push VRAM requirements higher.
As an NVIDIA card, the RTX 4070 Super gives you access to DLSS 4 super-resolution and Frame Generation, which can meaningfully lift frame rates in supported titles. The Radeon RX 7900 XTX counters with FSR 4, which is open-source and works across a wider range of games — including some that don't support DLSS. Which ecosystem matters more depends on the games in your library.
