Looks veery tasty, especially with having only a 120mm radiator - but again too expensive... :-(

Even a Fury X had more thicker radiator idk how this is gonna keep such a beast in check.

Yesterday i saw a watercooled 6900Xt from other brand being sold at 2.000€...

Like the reference 6900XT they made this XTXH one also only with 2xPCIe power connector so limited to 375W. 😉
It would be interesting to see how high this one clocks compared to other custom XTXH models with beefier power circuitry.
As I own 6900XTU Liquid Devil Ultimate, I know that XTXH cards like more power and good cooling to OC higher.
So not sure how high these can clock with only small radiator to cool it and with 375W power limit.
Mine has 3xPCIe power (525W limit).
My XTXH is set at 415W Core Power and 400A TDC by using MPT and runs 2750MHz@1175mV stable. With lower power target, this frequency was not stable in 3DMARK.
In games like Cyberpunk though Core power draw is in range of 330-350W at this OC.
Defult performance bios setting on Liquid Devil Ultimate is 332W Core Power and 320A TDC. If one uses the 15% slider in Radeon Software then this jumps to 381.8W and 368A TDC.
My card has EK block factory fitted but hotspot temperature were still hitting 92°C on this OC even with my custom loop with 3 rads that I have for cooling it together with 5900X.
I changed from standard paste to Liquid Metal and now hotspot temperatures remain below 78°C in burn in tests.
The VRM temperatures at 415W Core stress test remains in range of 55°C. The cold plate on EK block covers these as well.
The 18 Gbps is really interesting. If that is true, then this will mean memory running at 2250MHz. 🙄
That is the max value that can be set under Radeon software for the XTXH cards.
Usually on many 6800XT/6900XT cards the Time Spy score actual gets worst if memory is clocked higher than 2120MHz which is the same case on my XTXH card. So setting it to 2250MHz does not make sense on my card as performance is degraded.
It would be interesting to look into the Bios what setting AMD is using for this reference card to run memory that high without actually loosing performance.
Hopefully somebody who buys this card uploads his Bios using GPU-Z to TPU database.
Of course flashing of bios from one RDNA2 model to other does not work and bricks the card but one can maybe do similar settings using MPT. 🙄
