Notes on 7 values — test conditions and caveats
- 1AMD Radeon RX 7700 XT, Base clock: AMD publishes only Game (2171 MHz) and Boost clocks; no base clock appears on AMD's page.
- 2AMD Radeon RX 7700 XT, Memory bandwidth: AMD also lists 1995 GB/s 'effective' bandwidth including Infinity Cache; 432 GB/s is the raw VRAM figure.
- 3NVIDIA GeForce RTX 4080 Super, Recommended PSU: NVIDIA's 750 W minimum assumes a PC with a Ryzen 9 5900X; needs vary by configuration.
- 4AMD Radeon RX 7700 XT, Recommended PSU: AMD bases this rating on a Ryzen 9 7950X system; your needs may differ.
- 5NVIDIA GeForce RTX 4080 Super, Power connectors: Card takes a 16-pin 12V-2x6 connector; a 3x PCIe 8-pin adapter ships in the box for PSUs without a PCIe Gen 5 cable.
- 6AMD Radeon RX 7700 XT, Power connectors: Reference card uses two 8-pin PCIe power connectors.
- 7AMD Radeon RX 7700 XT, DisplayPort version: Notebookcheck specifies the DP 2.1 output at UHBR13.5 link rate.
Performance and power
The GeForce RTX 4080 Super relies on the Ada Lovelace architecture to reach 52 TFLOPS of FP32 compute power, outperforming the Radeon RX 7700 XT and its RDNA 3 architecture. That raw compute advantage demands more electricity, requiring a 320 W board power and a 750 W minimum power supply unit compared to 245 W and 700 W for the AMD card.
Buyers investing in the NVIDIA card must ensure their setup handles a 12V-2x6 power connector, whereas the AMD option uses standard 8-pin connections. Both power requirements vary based on the rest of the PC components.
Memory and rendering
The GeForce RTX 4080 Super packs 16 GB of GDDR6X video memory across a 256-bit bus, achieving a memory bandwidth of 736 GB/s. This configuration handles heavy loads far better than the AMD card, which relies on 12 GB of GDDR6 on a 192-bit bus.
With 64 MB of last-level cache on the NVIDIA card versus 48 MB on the competitor, texture streaming and complex frame rendering run with significantly more headroom on the high-end option.
Size and displays
The Radeon RX 7700 XT measures 267 mm in length and takes up 2.5 slots, making it easier to fit into compact chassis than the 304 mm long, 3-slot GeForce RTX 4080 Super.
For monitor connectivity, both cards provide three DisplayPort outputs and one HDMI port, but the NVIDIA card supports the slightly newer HDMI 2.1a specification.
The Verdict
Buy the NVIDIA GeForce RTX 4080 Super if you want maximum rendering power and memory bandwidth. Buy the AMD Radeon RX 7700 XT if you need a lower launch price and a more compact card.
