Conclusion

...Sapphire's unique Toxic card stokes the flames of temptation by imbuing RX 6900 XT with an all-in-one liquid cooler...

AMD's Radeon RX 6900 XT attracts a certain kind of customer. For most folk, cards further down the pecking order provide a better balance of performance and value, but such matters are of little concern to those who crave nothing but the best.

For those select few, Sapphire's unique Toxic card stokes the flames of temptation by imbuing RX 6900 XT with an all-in-one liquid cooler that extracts every last ounce of performance while keeping incredibly cool at all times.

An out-the-box boost clock of 2,365MHz makes this the fastest Radeon we've ever tested, the 360mm radiator also makes it the coolest, and single-click Toxic Boost overclocking takes any guesswork out of the equation. A heady combination, but the Toxic card isn't perfect. Ignoring the inevitable stock issues - which will be severe - there's also the matter of coil whine, pump noise and rambunctious fan profiles. Though this may be the fastest and coolest RX 6900 XT, it certainly isn't the quietest.

Bottom line: RX 6900 XT or RTX 3090? That's a whole other debate, but if you choose to side with team Radeon, they don't come any faster than the Sapphire Toxic.

looks like the tubes are a bit short for it, look a bit strained in the photo.

Any reason you mounted it that way round instead of having the tubes go on the left side which is less distance?

I think the exhaust fan is in the way of the tubes mounted the other way around

TL;DR = It's the undisputed fastest GPU in the entire world at 1080p & 1440p, but falls right behind the RTX 3090 at 4K. Basically, there's no surprises here at all. Thus if you have the choice of hardware & want the absolute MAXIMUM possible performance, 1080p or 1440p/high refresh rate = RX 6900 XT; whereas >=4K/anything = RTX 3090.

Those tubes are from the CPU cooler

*in some games, depending on the test setup and review site.

I'd rather say that it's pretty much equivalent to the 3090 at 1080p/1440p, but for £300 less. If you only game at those resolutions, have no interest in raytracing, and have the space & noise tolerance, it seems a good option.

For most others in the same situation, the regular 6900XT seems to be a better option…if you could find one of course ;) Tend to agree with your summary of no surprises here though, the Radeons still work out a better option if you have no interest in Ray tracing (and that's a huge percentage of people), and the nvidia options work out better if you do, or really want 4K gaming (which isn't many people!).
