How the calculator works
Normalized graphics performance is adjusted for resolution. Ray-tracing uplift also considers GPU vendor and generation signals, while power and VRAM come from catalog specifications where available.
GPU Upgrade Calculator
Compare a current and new graphics card across gaming, ray tracing, VRAM, power and efficiency.

How to interpret the result
Look beyond the headline gain. More VRAM can improve longevity, while a higher power requirement may also require a PSU or cooling upgrade.
Factors that affect the result
Results depend on the workload, game engine, drivers, cooling, power limits, memory configuration and background software. H2HBench uses normalized catalog and benchmark data, then reports confidence instead of presenting an estimate as a laboratory measurement.
Frequently asked questions
What is a worthwhile GPU upgrade?
Many users notice a clear difference around a 30–40% gain, but features, VRAM and minimum frame rates can matter as much as the average.
Does the estimate include ray tracing?
Raster and ray-tracing changes are shown separately when the available data supports an estimate.
Will a new GPU need a new PSU?
Check the reported power change with the PSU Calculator because transient spikes and the rest of the system also matter.
