A number helps.Knowing what to do helps more.

First you see what the computer actually did. Then VRAM Check explains what should run well and whether anything is worth changing.

Performance

How quickly can this computer run local AI?

We time how quickly it reads a prompt, starts responding, and continues writing. Then we repeat the test to make sure the result is steady.

Compatibility

Which models should run comfortably?

We compare your available graphics memory with each model's needs and clearly label what was measured versus estimated.

Next move

What should you improve, if anything?

See whether memory, speed, or system RAM is the real limit before spending money on an upgrade.

Fair comparisons.The same test.

Every ranked computer completes the same workload under the same rules. That makes the leaderboard a useful comparison, not a collection of unrelated screenshots.
