AMD Radeon RX 6900 XTX Engineering Sample Pictured
AMD is in constant progress with its Radeon graphics card lineup and the company is always working on new models that will better suit the market. Today, we have interesting discovery. On Weibo, a Chinese microblogging website, a user has posted pictures of what appears to be an engineering sample of AMD's Radeon RX 6900 XTX graphics card variant. Having an all-in-one (AIO) water-cooled design with a 120 mm radiator, the card resembles a power-hungry design as we have seen with Radeon R9 Fury X and RX Vega 64 Liquid Edition, which were both graphics cards equipped with AIO water cooling. This engineering sample is no different.
Under the waterblock, there is a Navi 21 XTXH GPU SKU hidden. As we found out, this is a new Navi 21 XTX SKU that just features better binning compared to Navi 21 XTX, and thus it offers better overclocking potential. It is already present in three new models from various AIBs, like the PowerColor RX 6900 XT Liquid Devil Ultimate, ASRock RX 6900 XT OC Formula, and Sapphire RX 6900 XT Toxic Extreme graphics cards. It seems like AMD has prepared itself to launch this specific SKU in a reference design form, however, so far only AIBs have used the Navi 21 XTXH SKU. It is not yet clear if the Radeon RX 6900 XTX is ever going to hit the retail market, or it shall remain as it is - just an engineering sample.

Have you ordered the RX 6900 XT, mod? :respect:
The problem with single loop custom water is that the CPU and tha GPU differs so much thermally that the limitations of the CPU makes GPU-cooling imbalanced. Because of that you need to bruteforce it with 3 tines bigger radiators.Then go and learn some thermodynamics. When the water hits 55°C in that AIO, the radiator is virtually becoming a 360 with 35°C water and 25°C ambient.

Small hint: Water permeation and pump failure, basically the AIO would die pretty quick under high water temp for extended period of time. Fury X have high rate of pump failure I think
Just googling Fury X pump problem and there are so many links about pump whine and failure...
Even D5 and DDC pumps would have a hard time surviving 50-60C water temp for a long time, not to mention these tiny AIO pump
In past, the Fury X was considered "hot" because its operating temperature around 80°C, at least in my unit. When compared to competitors like the 980 / 980Ti, it certainly looks bad especially the latter only equipped with regular fan. Now standard has changed, I don't worry anymore with 950mV undelvolt 1950Mhz clock 1300rpm fan hovering in 90°C range :laugh:
A 120mm rad CAN cool 300-400W, but the fan(s) will be going at 2000+ rpm and the coolant temp will be in the 50-60C range, plus the air coming out of it could be used to make beef jerky. The GPU will still be pretty cool, just due to the way they dump heat (and it's still probably better than the stock heatsink anyway) but I hope the el cheapo tubes, plastic/rubber gaskets, and the coolant itself is fine to be braising at that temp over time without breaking down.+1 I always try to split loops because of this, but you do want to keep your fluid temps at around 40C if possible on a gpu loop....
These aren't exactly automotive grade parts, and some weird and not so great stuff starts happing as you get to 60C on the coolant.
I remember that exist an 120 rad (thermalright IF im not wrong) that was able to hit more than 550 W at 30 mm thick :)
- OEM build quality is hit/miss. There are many problematic designs, even down to simple things like choice of materials, tubing, etc. And let's not begin about pump failure. Corners always get cut.
- More moving and individual parts than air cooling result in a simple fact: AIOs break faster and are much more prone to it. Even with a decent design. If you think otherwise, you're lacking objectivity.
- 'It lasts years'... exactly, number undefined. And when it dies, your hardware is likely still going or capable of doing so. Its a simple fact they die or get worse over time as gunk builds up slowly and motors go weaker. A heatsink and a fan lasts literally forever, and worst case you'll replace a 5-15 dollar fan over its lifetime, or two over your personal lifetime if you really grow attached to it :D
