Compared to the dedicated Radeon 5300M (also RDNA), the 680M should still be significantly slower. Therefore, the 680M should be the fastest integrated graphics card in early 2022. Thanks to the new architecture, high core count and the increased maximum core clock, the Radeon 680M should be clearly faster then the old Radeon Vega 8 iGPUs.
The 680M and 660M iGPUs are the first integrated graphics card with hardware raytracing support, although the performance is too slow to use it in current games. The iGPU is based on the RDNA2 architecture and has 12 CUs (= 768 shaders) clocked at up to 2,400 MHz (depending on the CPU model). The AMD Radeon 680M is an integrated GPU in the Ryzen 6000 series for laptops (Rembrandt, e.g.
