AMD Radeon RX 7900 XTX vs NVIDIA GeForce RTX 4080 Gaming Benchmarks

The Radeon RX 7900 XTX is AMD’s fastest RDNA 3 graphics card. Priced at $949, it competes with the GeForce RTX 4080 (and the 4080 Super). Despite being cheaper, it often delivers similar performance as its NVIDIA rival, even surpassing it sometimes. We compared the two high-end GPUs across a few dozen gaming benchmarks at 1080p and 1440p, with ray tracing cranked to ultra.

Specifications: Cores, Clocks, and Cache

On paper, the Radeon RX 7900 XTX has the RTX 4080 beat in most scenarios. It features 50% more memory than the RTX 4080 (24GB vs. 16GB), 50% more cache (96MB vs. 64MB), and a 50% wider bus (384-bit vs. 256-bit). Ergo, the RX 7900 XTX has a significantly better memory subsystem.

The GeForce RTX 4080 features more cores than the 7900 XTX (9728 vs. 6144), faster GDDR6X memory (22.4 Gbps vs. 20 Gbps), and lower power consumption (320W vs. 355W). The Radeon RX 7900 XTX has a clock speed rating of 2498 MHz, while the RTX 4080 is marketed at 2550 MHz. In reality, both GPUs run between 2.7 GHz and 2.8 GHz, depending on the power consumption and thermal conditions.

Test Bench

  • Motherboard: ASUS ROG Maximus Z790 Hero.
  • CPU: Intel Core i9-13900K.
  • Cooler: Lian Li Galahad 360.
  • Memory: 16GB DDR5 x2 @ 6,000MT/s CL30.
  • Power Supply: Corsair HX1000i.

Test Methodology

  • We tested the two graphics cards on a Z790 motherboard with a Core i9-13900K and 32GB DDR5 memory.
  • Eleven games were benchmarked at 1440p and 4K using the highest quality preset, followed by the highest ray-tracing quality preset at 1440p.
  • The performance is measured using the average FPS and 1% lows. The latter represents a figure higher than the lowest 1% frame rates. It’s used to gauge the performance in resource-intensive scenarios.
