ASUS RX 6600 XT Strix OC Review

ASUS RX 6600 XT Strix OC Review


Last week we gave you a sneak preview of the newest additions to the AMD Radeon range, based upon their RDNA 2 architecture. The day has finally come when we can reveal how it performs in our suite of gaming benchmarks.

If you paid attention only to forums, Reddit or influencers it would be easy to come away with the belief that the entire world runs the very latest hardware on displays that wouldn’t look out of place in your local Odeon. Thanks to the Steam hardware survey we know that 1080P is still, by some margin, the dominant gaming resolution and that way more people run cards which are designed to push that resolution at an affordable price, than the flagship models.

With any new hardware release there is always a lot of pomp and ceremony about the new range-topping models, because they are the ones we all dream of, but beneath those shouty cards there are the ones that sell in numbers you can barely imagine. The meat and potatoes of the range if you will. When it comes to selling cards by the million the ASUS Strix range has that locked down, thanks to the fame of the ROG name and particularly the Strix sub brand. Combining the ROG Strix name with a hugely popular price point should ensure that the Radeon RX 6600 XT flies off the shelves.

Spoiler alert, the RX 6600 XT is the perfect choice if you want a 1080P gaming card at a price that doesn’t require you to sell a kidney or live in a cardboard box.

Technical Specifications

AMD handily provided us with a comparison between the new RX 6600 XT and the card in their range that it replaces, the RX 5600 XT. It’s fair to say the new affordable-gaming focussed card has seen a significant upgrade in hardware. We can’t wait to see how it performs in our gaming tests.

The ASUS Strix itself has a couple of additional elements to note. Outputs are 1 HDMI 2.1 and three DisplayPort 1.4a connectors. The GPU itself has seen a little boost on this OC edition, now running 2607 MHz boost and a more substantial 2448 MHz game clock. We know that there will be more to come when actually running it, but those are the ‘on paper’ figures.
