Pros And Cons

Comparison Table

Architectural Differences

• Process Size: Nvidia uses cutting-edge 4nm processing nodes for its Ada Lovelace GPUs, whereas the RX 7800 XT employs a chipset design that uses 5nm and 6nm processing nodes to keep costs down and efficiency up.
• Clock Speed: The RTX 4080 has a base clock of around 2205MHz, much higher than the RX 7800 XT’s 1295 MHz. Their boost clocks are similar, with the RTX 4080 at around 2505 MHz and the RX 7800 XT slightly lower at 2430 MHz.
• VRAM: These cards have 256-bit 16GB of VRAM, but the RTX 4080 has faster memory using GDDR6X technology compared to the GDDR6 of the RX 7800 XT. The RTX 4080 also boasts a memory bandwidth of 716GB/s, outclassing the RX 7800 XT’s 620GB/s.
• TDP: The RTX 4080 is rated to consume up to 320 watts of power, which is low for such a high-end card. The RX 7800 XT undercuts this further with a TDP of only 263 watts.
• Other Features: In terms of nice-to-have features, Nvidia takes the cake. It has better ray tracing, better-looking image upscaling, ray reconstruction, and frame generation.

The RX 7800 XT has a great price-to-performance ratio, unlike Nvidia’s RTX 4080, which packs as much power as possible without regard for the hole in the consumer’s wallet it will leave. This comparison will pin the RX 7800 XT vs RTX 4080 against each other to see if either approach holds any water against the other.

Gaming Benchmarks

To assess the performance difference between the RX 7800 XT vs RTX 4080, we tested the gaming performance of these GPUs to gain deeper insights into their capabilities. We played taxing games at 4k resolution with close to Ultra settings in all games.

A Plague Tale Requiem

• Kicking things off with A Plague Tale Requiem, we saw that the RTX 4080 quickly eliminated the RX 7800 XT with a 50% lead. The RTX 4080 had a 77 FPS average, whereas the RX 7800 XT managed only to reach an average framerate of 51 FPS.
• In terms of low 1%, the RX 7800 XT maintained around 45 FPS. In contrast, the RTX 4080 was comfortably cruising over with 67 FPS.

Resident Evil 4

• During Resident Evil 4, the RX 7800 XT got an average framerate of 74 FPS, whereas the RTX 4080 managed an average of 108 FPS. This computed out to the RTX 4080 being 45% more performant in this game.
• 1% lows deviated similarly between the two cards as their average framerates, with the RX 7800 XT getting around 66 FPS, whereas the RTX 4080 stuttered down to around 97 FPS when there was a lot of action on-screen.

Cyberpunk 2077

• In our Cyberpunk 2077 session, the RX 7800 XT had an average framerate of 45 FPS, whereas the RTX 4080 had a framerate of around 62 FPS, meaning that the gap in performance was reduced to around 38% in this game.
• Despite the low average framerates of these cards, the 1% lows did not fall far from the tree. The RTX 4080 got down to 57 FPS when the intensity was dialled up, whereas the RX 7800 XT got down to around 40 FPS.

Hogwarts Legacy

• The RTX 4080 regained its substantial lead in our Hogwarts Legacy gameplay by delivering 41% higher performance. The RX 7800 XT averaged 51 FPS on the ultra preset, while the RTX 4080 performed better at 72 FPS.
• In the worst 1% performance time, the RTX 4080’s performance got bumped down to as low as 50 FPS. The RX 7800 XT was not immune to this either, getting a minimum framerate of around 40 FPS.

Forza Horizon 5

• We saw a pretty large 40% advantage for the RTX 4080 in Forza Horizon 5. The RTX 4080 had an average framerate of 141 FPS, whereas the RX 7800 XT was a much lower yet smooth 101 FPS average.
• The RTX 4080 did not experience large dips in performance, with the framerate dropping to 125 FPS at times, whereas the RX 7800 XT’s 1% lows felt more jarring, with the framerate dropping to around 83 FPS.
