The reference blueprint calls for a 1,825MHz base clock, 2,105MHz game clock, and 2,250MHz boost clock. It also features 16GB of GDDR6 memory on a 256-bit bus, for 512GB/s of memory bandwidth. This all translates into 23.04 TFLOPS of single-precision compute performance, and 46.08 TFLOPS of half-precision performance.
Now, onto the custom cards…
ASUS TUF Gaming Radeon RX 6900 XT
“The barrier rings on the side fans have been slimmed down to allow for more lateral intake and to provide better airflow through the cooling array. The center fan’s extra blades and full-height ring provide boosted static pressure to blast air directly onto the GPU heat spreader. The fan design growth is specifically optimized for a massive new heatsink that features more fins and surface area than previous iterations,” ASUS explains.
Underneath it all is full-length, finned aluminum heatsink, covered with an all-aluminum shroud, reinforced frame, and a metal backplate for added durability. There is also a “MaxContact” heatspreader with a “super flat surface” to pull heat from the GPU. The whole contraption is designated as a 2.9-inch slot design, meaning it effectively takes up three expansion slots.
ASUS claims this results in a cooler and quieter running card. There is no mention of the clockspeed(s), though the model number suggests this is a factory overclocked card. Additionally, it sports two BIOSes, which is usually a telltale sign of a factory overclock as well (though that is not always the case).
Pricing and availability have not yet been announced.
ASRock Radeon RX 6900 XT Phantom Gaming
It also features a brushed metal backplate for added durability. Beyond that, however, ASRock is still mum on the key details, those being the base clock, game clock, and boost clock. Each one is listed as “TBD” on the card’s product page. However, we know it will sport a factory overclock of some kind.
Pricing and availability have yet to be announced on this card as well.
