ASRock OC Formula Radeon RX 6900 XT 16GB BUY
The Radeon RX 6900 XT GPU at the heart of the ASRock RX 6900 XT OC Formula isn’t the same chip as the one in the RX 6900 XT Phantom Gaming. AMD refers to this silicon as the Navi 21 “XTXH.” It is the highest bin of the Navi 21, designed to sustain up to 10% higher clock speeds than the regular RX 6900 XT. With its default “performance” BIOS, the RX 6900 XT OC Formula can now boost up to 2475 MHz and achieve game clocks of up to 2295 MHz. The reference AMD Radeon RX 6900 XT sustains only up to 2250 MHz boost and 2015 MHz game clocks, while ASRock’s previous RX 6900 XT-based flagship, the RX 6900 XT Phantom Gaming, does 2340 MHz boost with 2105 MHz game clocks. Compared to the reference design, that’s exactly a 10% OC from ASRock.
