Clock gain and overclocking reserves
The indirect gain due to better cooling can also be seen again. Instead of 2.474 GHz over an average of 25 minutes, the card now achieves a clock rate of just under 2.600 MHz in a warmed-up state compared to the original, air-cooled variant and also allows itself around 8 watts less TBP on average at the power supply. Furthermore, the progression of the clock rates is much more balanced, which even leads to smoother scrolling in the end because less downsampling is required. If you overclock and work with a TGP of 375 watts instead of 325 watts, the advantage in power consumption is of course history again, but the card now clocks to just under 2.8 MHz on average over 25 minutes of gaming in ultra HD!
The overclocking of the air-cooled card, on the other hand, was quite pointless, because it already loses a lot of clock in its state of delivery. Counteracting this with more power would also mean risking higher temperatures, which would then in turn lead to a clock reduction. Dog-tail principle, in other words. Water must be used and at least the upgraded AiO if it is not to be a real custom solution or the chiller.
Summary and conclusion
Just because of the really excellently low surface temperature, the Eiswolf 2 in this interpretation for Sapphire’s RX 6950 XT has earned a real buy tip, especially since it fits both the Nitro+ and Nitro+ Pure as well as all the Toxic variants as AiO. The build quality has also gone up once again, you can see that Alphacool has made changes to the manufacturing (and fabricator) in addition to the design in recent months. The new thermal pads don’t disgrace their name either.
You can no longer see any tool marks or sharp burrs, the fit is exemplary and the threaded inserts on the water block are also nice and tight. The price of just under 245 Euros including the backplate is actually quite acceptable, since the hybrid AiOs on the Toxic variants are actually just repurposed CPU coolers from Asetek for the GPU with some air cooling for the rest of the board. Why one would really use such a compromise as water cooling, no idea.
The RGB look, on the other hand, is, as always, a matter of taste, and some people will certainly have reservations about acrylic in general. Here, you simply have to give the eye a certain say in addition to the brain, you have to be that fair. But the target audience will like it, I’m already very sure of that. And what are the other manufacturers doing? I have yet to see a similar solution, much less one with an additional CPU option. That’s why the award is okay, because I like unusual solutions away from the boring Asetek mainstream.
The test samples were provided by Alphacool and Sapphire, there was no influence on the tests and the results.
