NVIDIA GeForce VS AMD Radeon GPU COMPARISON
Compare RightNow GPU Database specifications and median 3DMark Time Spy Graphics scores. The quick answer below is intentionally separated from game-specific FPS and live pricing.

Ampere · 10 GB GDDR6X
RDNA 4.0 · 16 GB GDDR6
QUICK ANSWER
RX 9070 XT has a median Graphics score of 29,561 versus 17,664 for RTX 3080, a lead of about 67% in this synthetic workload.
3DMARK TIME SPY
Median Graphics scores across submitted 3DMark Time Spy results; higher is better.
Time Spy is a synthetic DirectX 12 workload, not an FPS guarantee. Submitted results can include different board models, drivers, cooling, overclocks, and laptop power limits. Models are desktop GPUs unless explicitly labeled Laptop.

HOW TO CHOOSE
A useful choice depends on performance, memory, power, price, and the games or workloads you actually use.
RX 9070 XT has a median Graphics score of 29,561 versus 17,664 for RTX 3080, a lead of about 67% in this synthetic workload. Treat a result within roughly three percent as effectively close in this synthetic workload.
RTX 3080 lists 10 GB GDDR6X and 320 W graphics power; RX 9070 XT lists 16 GB GDDR6 and 304 W. Board-partner models can use different coolers, limits, and connectors.
This comparison does not invent FPS or value claims. Check independent testing for your games and resolution, then compare the current prices of the exact cards available to you.
