12% Higher Core and Memory Clocks, 10% Higher Power.
Taken from TPU … A leaked SKU sheet posted to Twitter by VideoCardz confirmed that AMD is indeed positioning the Radeon RX 6900 XT Liquid Cooled (LC) as a SKU separate from the RX 6900 XT. The finalized specs reveal that the card features Game Clocks of 2250 MHz, compared to 2015 MHz of the stock (air-cooled reference) RX 6900 XT; while the memory now operates at 18 Gbps (GDDR6 effective), compared to 16 Gbps on the reference card.
This gives the GPU a memory bandwidth of 576 GB/s, compared to 512 GB/s on the reference. To support these, the TBP (total board power) value is increased by 10%, and is now at 330 W, compared to 300 W on the reference RX 6900 XT. The RX 6900 XT LC lugs an all-in-one, closed-loop, liquid cooling solution, while drawing power from the same two 8-pin PCIe power connectors as the original RX 6900 XT.
