AMD’s midrange RDNA 2 graphics cards could offer more overclocking potential than anyone might’ve expected. Igor Wallossek has gotten his hands on two custom Radeon RX 6700 Series (Navi 22) BIOSes, which show impressive maximum GPU clocks in the range of 2,854 MHz and 2,950 MHz. The BIOSes also reveal power limits of 186 and 221 watts, alluding to a reference and premium model.
“The Radeon RX 6800 has a TGP of 203 watts as reference card,” Igor notes. “The 186 watts of the BIOS 1 would therefore be 92% of the TGP, which also suggests an OC BIOS in view of the smaller memory (12 instead of 16 GB GDDR6). The BIOS 2 is even clearly above what AMD already gives the RX 6800 reference card!”
The maximum GPU clocks listed here are amusing because it was recently reported that AMD’s Radeon RX 6800 Series are limited to 2.8 GHz. Apparently, the Radeon RX 6700 Series can clock higher than the Radeon RX 6800 Series, even coming close to the Radeon RX 6900 XT, which is allowed to hit 3.0 GHz.
Igor believes that the first BIOS is for a model with a single fan, as 2,300 RPM would be oddly high for dual- or triple-fan configurations. The other model, which features a 1,700 acoustic limit, is likely a dual-fan design.
