While the Radeon RX 6800 XT and RX 6800 (test) have a fixed clock limit of 2.8 GHz, AMD is to release the Radeon RX 6900 XT with up to 3 GHz and thus a greater scope for overclocking. Custom designs in particular could benefit from this. The Sapphire Radeon RX 6800 XT Nitro + (test) already reached almost 2.7 GHz.
Radeon RX 6900 XT with 200 MHz more headroom
Once again, it is the usually well-informed Twitter user @patrickschur_, which shares this information about the higher clock limit of the Radeon RX 6900 XT compared to the Radeon RX 6800 XT and the RX 6800. The maximum adjustable GPU clock is therefore 200 MHz higher for the Navi 21 XTX than for the Navi 21 XT and Navi 21 XL and is expected to reach the 3 GHz mark for the first time.

With 80 compute units and the resulting 5,120 ALUs, the Radeon RX 6900 XT will attack the GeForce RTX 3090 (test) from competitor Nvidia from December 8th. However, it should be said that clock rates of more than 2.8 GHz should be more interesting for water-cooled graphics cards and will not be the rule.
