Pros And Cons

Comparison Table

Architectural Differences

1. Clock Speeds: The RTX 4070 Super surpasses the RX 7900 XT in clock speeds, boasting a base frequency of 1980MHz and a boost frequency of 2475MHz, outperforming the RX 7900 XT’s base and boost clock speeds.
2. VRAM: The RX 7900 XT takes the cake regarding VRAM, with a buffer size of 20 gigabytes of GDDR6 memory carried over a 320-bit bus. In contrast, the RTX 4070 Super has 12 gigabytes of GDDR6X VRAM, carried over a narrow 192-bit bus.
3. TDP: Nvidia set the RTX 4070 Super’s TDP at 220 watts, significantly lower than the RX 7900 XT’s 300 watts, requiring a larger recommended power supply for the RX 7900 XT.
4. Processing Nodes: Nvidia and AMD used the same 5nm processing nodes with the RTX 4070 Super and RX 7900 XT, both companies supplied by TSMC.
5. Other Differences: The RX 7900 XT aligns with the RTX 4070 Super in features like AI upscaling and frame generation. However, Nvidia’s polished, tailored approach outshines AMD’s open-source strategy, which can lead to some issues in fit and finish.

The release of the RTX 4070 Super marks a pretty significant refresh for the new Nvidia xx70 card. Let us see how it compares to one of the best cards from AMD in the RTX 4070 Super vs RX 7900 XT comparison.
