Use Tool ➜About Gaming Performance Tools
TechCompare's gaming tools help you reason about PC performance before and after an upgrade. Benchmark your GPU directly in the browser with real WebGPU workloads, see exactly how much smoother 120 FPS looks compared to 60 FPS, and estimate how long that 120 GB game will take to download at your connection speed.
Use this category when building a new rig, comparing GPUs across review benchmarks, or deciding whether a high-refresh monitor upgrade is worth it for the games you actually play. The WebGPU Benchmark gives you a reproducible score to compare against other hardware; the FPS Visualiser and Data Transfer Calculator fill in the perceptual and practical context around raw numbers.
Frequently asked questions
How accurate is a browser-based WebGPU benchmark?
The WebGPU Benchmark runs a real compute workload against your actual GPU, so relative scores between devices are meaningful. It won't match a native 3DMark result because the browser adds overhead, but as a quick way to compare two machines or track whether a driver update helped, it's a useful reference.
Can I really feel the difference between 60 FPS and 144 FPS?
Yes — especially with mouse input and camera motion in first-person games. The FPS Visualiser shows the actual motion smoothness difference by animating moving objects at both rates side-by-side, so you can judge it for yourself instead of relying on second-hand opinions.
Why is my game downloading so slowly?
Almost always because of your connection, not the storefront. The Data Transfer Calculator converts a file size into an expected time at any Mbps value; a 100 GB game at 50 Mbps is roughly 4.5 hours, which is what the physics predicts regardless of which platform you're using.
Do these tools work on consoles or phones?
The visualisers and calculators work on any modern browser including mobile Safari and Chrome on Android. The WebGPU Benchmark needs a browser with WebGPU support — Chrome, Edge, desktop Safari 17+, and most recent Chromium-based Android builds all qualify.
Can I use these to choose between two graphics cards?
The WebGPU Benchmark gives a directly comparable score if you can run it on both cards. Combined with the FPS Visualiser (for judging refresh-rate feel) and the Power Cost Estimator (for annual running cost), you get a fuller picture than raw FPS charts alone.
