Inno3D RTX 4080 iChill X3 Review

For our manual overclocking tests, we used MSI Afterburner. Our best results are as below.

Of course, we did try to manually overclock the card ourselves, but it’s important to note that you can’t actually increase the power limit of the card – it’s locked at 100% and cannot be raised above 320W. Inno3D told us this is because it doesn’t actually affect overclocking, considering the 4080 is voltage limited and not power limited. That does seem to be the case based on my findings, though it can depend on the scenario and specific game.

We were still able to add 115MHz to the GPU and 1770MHz to the GDDR6X memory.

Over our 30 minute stress test, the card did run a bit slower than the likes of the Gaming OC, averaging 2869MHz.

In our game benchmarks, the iChill X3 is right on the heels of the Gaming OC, with the overclock providing a performance uplift of around 6-7%.

Power draw didn’t increase either, as we didn’t raise the power limit.
