There’s a new AMD RDNA 4 clock speed rumor in town, with a new claim appearing suggesting the company’s upcoming GPU architecture could have a significantly higher boost clock speed than its current generation of GPUs as well as Nvidia’s latest offerings.

The new AMD RDNA 4 speculation comes via regularly rumor-monger Moore’s Law is dead (MLID), who claims that the latest RDNA 4 specs rumors show engineering samples of the chips clocking all the way up to 3.30GHz. That compares to just 2.50GHz for the likes of the AMD Radeon RX 7900 XTX and is a huge 48% higher than the 2.24GHz clock speed of the Nvidia GeForce RTX 4090 – both cards that make it onto our best graphics card guide.
