Compute
Sustained FP32 and FP16 throughput, measured on your card with real work, not read off a spec sheet.
Recorded in TFLOPS, FP32 and FP16
Measure whatyour cardreally does.
The zgpu benchmark is free. It loads your card the way real work does, records what it can sustain, and turns that into one score, plus tuning advice for gaming.

What the score measures.
Four things decide how much work a card can actually finish. The score combines them, and every number behind it is kept with your result.
Memory bandwidth
How fast your card moves data to and from its VRAM. Rendering leans on it as hard as it leans on compute.
Recorded in GB/s
Efficiency
Your score divided by average power draw during the run. Two cards with the same score aren't equal if one needs more power to get there.
Recorded as score per watt
Stability
A deterministic check computation that has to give the same answer every time. A fast result that comes out wrong is marked unstable.
Recorded as pass or fail, with a result hash
Every run keeps its telemetry.
The app samples your card while the benchmark runs, so a score always comes with the conditions that produced it.
- Peak GPU temperature
- °C
- Average graphics clock

When a score counts as verified.
The leaderboard checks every result against its own telemetry. A result that fails a check still shows, marked unverified.
- Power draw
- above zero
- Graphics clocks
- within the card's maximum
- Stability check
- passed
- Against its own model
- at most 1.5× the median
The median check starts once a card model has 10 or more scores.
Tuning advice for gaming.
After a run, the app tells you what's holding your card back and what's worth changing. Here's the kind of advice you get.
Power-limited
Your card hit its power limit before its temperature limit. Raising the power limit, within NVIDIA's range for your card, may let it hold boost clocks longer.
Running hot
Core temperature climbed close to its limit. Improve airflow before you raise any limit.
Headroom to save
Your card held its clocks with power to spare. A slightly lower power limit can run it cooler and quieter.
Unstable
The check computation came out wrong. Go back to stock settings before you trust any score from this card.
Advice is a recommendation. Nothing is applied unless you confirm it, and only inside NVIDIA's own limits for your card. Tuning is for desktop PCs only.
Run it when early access opens.
Early access starts with gamers and overclockers. Your score can go on the board the day you run it.
