Is it worth upgrading?

A newer card winning every row of a comparison table does not make it worth buying. This works out how much faster it actually is at your resolution, what that improvement costs per percentage point, and whether a cheaper card would get you most of the way there.

Both cards have to be ones CompareYourGPU tracks. The database currently covers current and recent desktop cards, so if you are coming from something older it may not be listed yet. See what is covered.

In favour: Estimated frame rate moves from roughly 90-130 FPS to 135-190 FPS.
In favour: 4 GB more memory.
In favour: 50% stronger in ray-traced workloads.
In favour: Works out at about $43.7 per percentage point of performance gained.

What it costs you

Where these numbers come from

Performance gain: CompareYourGPU estimated index, native resolution, no upscaling.
Measured cross-check: third-party suite rating, run with vendor upscaling at Quality. Not directly comparable with the native estimate, which is why both are shown.
VRAM, board power and features: manufacturer specifications.
Prices: verified current street prices.
The cost of the upgrade is the price of the new card. CompareYourGPU does not model what your current card might sell for.
