AMD’s newly announced Ryzen 7000 CPUs offer stellar single-threaded performance, outpacing their Zen 3 predecessors by a haughty 20-30% across various workloads. The multi-threaded gains, while higher, may result in Team Red losing the content creation crowd to the 13th Gen Raptor Lake family.
What no one is talking about though is that the RDNA 2 iGPU featured on the Raphael processors are more powerful than they seem.
As pointed out by Kirby Louise on Twitter, although we get only two Compute Units (CUs), they have a boost clock of 2.2GHz, resulting in a single-precision compute performance of 550 GFLOPs. That is more than the theoretical compute performance of the NVIDIA Tegra X1 powering the Nintendo Switch. Since we’re talking about two completely different architectures here, it’s not a real-world comparison but is impressive nonetheless.
The Nintendo Switch with its 256 CUDA cores and a core clock of 302-768MHz manages an FP32 compute performance of up to 393 GFLOPs, making the dual-CU RDNA iGPU on Zen 4 a notably faster part.
