Unknown GPU, bad DirectX performance.

[Jocaru]

Hello all, new in the forum and first post!

Recently I got a laptop (Thinkbook 16p Gen 6) that seems to not be officially released yet (bought from a second-hand app), when checking the specs, the GPU just appears as "NVIDIA Graphics Device", after investigating it seemed to be a RTX 5060 Mobile so I waited until drivers released yesterday. I installed them using nvcleaninstall, as using normal method didn't detect the GPU as compatible, but something seems to not work correctly at all.

Before installing the latest drivers, I installed the ones that came from the laptop in the hard drive (unsigned 571.31 beta drivers) and tried to do some tests, in Unigine Heaven DirectX 11 performace was horrible, like 7fps @1080p, but when using OpenGL performance was better, but not what I would expect (35~50fps). In both cases GPU-Z shows 100% GPU usage, but temperature doesn't raise a lot (stays around 60ºC). After installing the 576.52 drivers, there are no changes at all in performance.

What made me suspect it was a RTX 5060 Mobile is the device ID, it's 10de-2d2c, and here is showing as GB6-128 plus HWInfo identifies it as GB206 GPU. The thing is that the specs shown in GPU-Z doesn't match at all with any GPU that I can find in Techpowerup's database.

Is there any way I can make this GPU work fine, or to at least identify which one is it? Any other ideas of what can I do with it?

for us to really identify. You are going to need to open up the laptop. remove the heatsink and take pictures of the bare GPu die for us.

Fixing this might be a problem though as both the bioses for the MB and GPu are normally contained on one single chip. So even if you do find the right chip its not going to be a easy fix

Sadly I'm not brave enough to remove the heatsink. I already opened the laptop to add a second nvme drive, but don't want to ruin something removing the heatsink.

Take it down to a repair shop then. Maybe they'll know what to do with it. Otherwise you are stuck.

Indeed your specs are weird, looks like an "enhanced"(?) - proprietary(?) 5060 mobile

Already looked at it and it doesn't match anything.

I just found that Lenovo put this page live: https://psref.lenovo.com/Product/ThinkBook_16p_G6_IAX?tab=spec , there it says it can come with a RTX 5060 or RTX 5070, having the Ultra 9 275HX I would guess it should be the RTX 5070, but it may be an engineering sample.
