AMD Liquid-Cooled Reference RX 6900 "XTX" Tested on 3DMark

PC enthusiasts on the Bili Bili community posted the first performance benchmarks of the Made-by-AMD liquid-cooled Radeon RX 6900 XT graphics card, which has been doing rounds on the rumor mill as an "XTX" part. This card features engine clock speeds in the league of the recent RX 6900 XT "XTXH silicon" factory-overclocked cards, but its more striking specification is the use of 18.48 Gbps-rated GDDR6 memory (15.5% increased memory bandwidth), and liquid cooling. The engine clocks are set at 2250 MHz game, with 2435 MHz boost.

Tested across 3DMark Time Spy, Time Spy Extreme, Fire Stike Extreme, and Port Royal, the card is tested to be anywhere between 5-8 percent faster than an air-cooled reference RX 6900 XT card. This would put it slightly behind the custom RX 6900 XT ("XTXH silicon") cards, though a significant upgrade from the air-cooled card. Coreteks in a recent report stated that the liquid-cooled reference RX 6900 XT is being targeted exclusively at the SI (system integrator) market, and so far, the card has only been spotted in China.

AMD needs to have an offer open- 1 per household, receipt required, trade in your Vega64 Liquid, get $150 off MSRP and actually get this card for GAMING. Not mining.

They're already gone. All we can hope for is a GT 730. This is the way.

18.48 Gbps is really great. :D
It would be interesting to see how AMD achieves this on this card.
They are OCing the memory significantly.

On many 6800XT/6900XT actually the performance degrades if one pushes the memory speed higher than 2120MHz.

My 6900XTU Liquid Devil Ultimate (XTXH card) also does not get higher than that on memory without loosing performance.
I can set slider to 2250MHz but higher than 2120MHz, the performance starts to degrade.
It seems like they are using some other bios setting for memory.
Maybe higher memory voltage on this model?

My 6900XTU Liquid Devil Ultimate runs stable at 2750MHz@1175mV now imagine that I could also push memory to 18.48 Gbps. That will give me even higher performance boost. :D
