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.

Ada Lovelace · 24 GB GDDR6X

Blackwell 2.0 · 16 GB GDDR7
QUICK ANSWER
RTX 4090 has a median Graphics score of 36,300 versus 33,013 for RTX 5080, a lead of about 10% 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.
RTX 4090 has a median Graphics score of 36,300 versus 33,013 for RTX 5080, a lead of about 10% in this synthetic workload. Treat a result within roughly three percent as effectively close in this synthetic workload.
RTX 4090 lists 24 GB GDDR6X and 450 W graphics power; RTX 5080 lists 16 GB GDDR7 and 360 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.
