AMD’s next-gen Radeon RX 7000 GPUs leveraging the RDNA 3 graphics architecture will reportedly sport boost clocks as high as 4GHz. That’s over 1.0 GHz higher than the RX 6900 XT, which tops at 2.25 GHz on the reference model. The rumor comes from @9550pro who has a pretty clean track record among Twitter’s tipsters.
According to HXL, the upcoming Navi 3X graphics cards will run at frequencies nearly approaching 4.0 GHz. NVIDIA has ramped up the operating frequencies of its GeForce RTX 40 series GPUs to approximately 3.0 GHz but AMD appears to have once again one-upped its green competitor in the clock department. This is quite an achievement as both the graphics families are fabbed on TSMC’s 5nm N5 process node.
Power efficiency and operating clocks have been one of the key pillars of the RDNA graphics architecture. RDNA 2 improved performance per watt by over 50% and the same is expected from RDNA 3. The frequency was bumped by 1.3x with RDNA 2, and it won’t be surprising if AMD manages to boost it by twice as much with RDNA 3. Navi 3x features not only a new microarchitecture but a much superior process node as well. As such, a boost clock of 3.5 GHz to 4.0 GHz on the RX 7900 XT and the 7800 XT is very plausible.
