How much is it?If it is more than 1200$，it will be too expensive

The person posting their Cinebench 2024 score of their Zephyrus G14 didn't actually have a Ryzen 9 8945HX. They had a Ryzen 9 8945HS instead, so I don't know why that was posted here.

The 8945HX also uses Radeon 610M iGPU, so we should expect the iGPU to have the same perf as other CPUs like 9955HX, 9955HX3D, 7945HX, etc.
