AMD Radeon 660M graphics is an integrated graphics card for Ryzen 5 6000 Series laptop/notebook CPUs launched on Jan 4th, 2022. It was codename as “Rembrandt“. It is a cut-down version of the Radeon 680M iGPU.
The GPU was later Refreshed as “Rembrandt+” and launched on Jan 3rd, 2024 for Ryzen 3 and 5 7000 series Laptop CPUs. All the Specs are similar, there is just a change in the naming scheme for the Ryzen 5 7000 series.
The only difference is in the Ryzen 3 7000 series Laptop CPUs which come with Radeon 660m 4 CUs and 1800 Mhz clock speed. A low-profile version for low-performing CPUs.
I have collected all the data from reputable sites like Techpowerup, Notebook-Check, etc. for the specs and performance of the Radeon 660M GPU.

GPU Frequencies
In desktop/notebook GPUs, the graphics cards are tuned according to their manufacturers/Board partners, depending on which frequencies they want in their notebook/desktop GPUs.
If they want power efficiency, they want to tune the frequencies lower than normal, resulting in less power consumption and loss of performance.
If they want performance, they will either let the frequencies default or tune the frequencies a little higher for more performance. Hence, the GPU will consume more power.
The Higher the clock speed, the better the performance of the GPU.
