HOW TO CHOOSE
Should you choose RTX 5070 or RTX 3080?
A useful choice depends on performance, memory, power, price, and the games or workloads you actually use.
Start with measured performance
RTX 5070 has a median Graphics score of 22,708 versus 17,664 for RTX 3080, a lead of about 29% in this synthetic workload. Treat a result within roughly three percent as effectively close in this synthetic workload.
Check memory and power
RTX 5070 lists 12 GB GDDR7 and 250 W graphics power; RTX 3080 lists 10 GB GDDR6X and 320 W. Board-partner models can use different coolers, limits, and connectors.
Verify the exact game and price
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.
