Custom Radeon RX 6000 Series GPUs Could Have Boost Clocks As High As 2.58 GHz

The specifications for AMD’s highly anticipated Radeon RX 6000 Series graphics cards have begun leaking out over the past few days. Something that’s become apparent is how much higher the boost clocks are in comparison to the Radeon RX 5000 Series, but there is growing indication that we ain’t seen nothing yet.

Igor Wallossek has gotten his hands on the BIOS for a third-party Radeon RX 6000 Series GPU and discovered that the GPU clock was set at an impressive 2.577 MHz. That happens to be 597 MHz faster than the Radeon RX 5700 XT 50th Anniversary Edition’s boost limit (1980 MHz).

While this doesn’t necessarily mean that custom RDNA 2 cards will actually clock that high, it does hint at higher than expected performance. Based on the 2.577 MHz clock speed, Wallossek estimated that third-party variants will typically feature boost clocks in the 2.3 to 2.4 GHz range, while gaming clocks should land in the 2.1 to 2.3 GHz range.

What’s also interesting is the custom card’s maximum graphics clock, which is set to an incredible 2.8 GHz. They should be a lot fun for extreme overclockers with exotic cooling solutions.

According to this morning’s leak, the reference Radeon RX 6900 XT will feature a 2330 MHz boost clock and 2040 MHz game clock, while the reference Radeon RX 6800 XT will feature a 2250 boost clock and 2015 MHz game clock.
