13500T shows AlderLake-S GT1

Featured Replies

i assembled a new Unraid, with Asus B760M-A and Intel 13500T, yet after installed Intel GPU top and GPU statistics, the GPU shows driver is I915, and GPU is AlderLake-S GT1.

and we know that for the 13rd Gen Intel CPU 13500T, GPU should be GHD 770, Raptor Lake.

i think it may be casued by the driver i915, but how can i get right driver?

The 13500 is technically an Alder Lake refresh though, not true Raptor Lake which was an updated architecture and had more cache, the device ID for the 13500T's version of the UHD770 is the same as the 12600K etc. which is 0x4680. I don't think there are actually any real-world differences in the iGPU architecture at all though, it's all UHD770.

The 14600k for example has a different device ID for its version of the UHD770, 0xA780, that does show as "Raptor Lake-S GT1 [UHD Graphics 770]" despite having the same iGPU specs, same CUs, same Video Engines, Clock speeds etc...

The 13600T and higher also have the newer Raptor Lake iGPU Device ID, but not the 13500, or even the 14500, they have the older device ID as they are both technically still Alder Lake refreshes, not Raptor Lake.

thanks for the explaination, so it's no problem for showing Alder lake.... That makes me relieved.
