4 iMac 2011 27' got 0 score in Nova benchmark for GPU
Dear iMac fairies
can u tell me what it means if nova benchmark test is zero for GPU? the photo displayed full result.
because the imac reboots frequently every few minutes for 3 weeks. i am identifying the failure cause.
Update (06/25/2022)
Matthew-x83.com detected 2 stuff, but did not specify which stuff is used more. 280 mark was given.
But Macs Fan control indicated higher temperature in GPU at 31C than in CPU at 29 C.
My question is still here...is GPU working ,but only running slow compared to other GPU?
Questa è una buona domanda?

Sorry its not! What you are seeing is the Intergraded graphics engine running here.
So let's start off with the temp sensors. You have a pan on a stove boiling water you place your hand above you feel the heat in the steam. So you know the water is hot but if you place your hand on the stove top that is not intended to get hot its also warm! This is also the same effect you are seeing here the CPU and power supply inside not only heat up but the other parts do as well and these sensors will show a temp as you discovered.
So here the GPU is getting power! And a short within it will also create heat! That doesn't mean the part is working or working correctly.
So why do these benchmark apps see the AMD GPU? Quite simply they are reading the value held in the OS it is not probing the GPU its self. So if I took out the GPU board it will still show the GPU logic is present until I reset it.
Depending on the OS-X/macOS Apple didn't even show you the CPU's graphics engine! It would only show the discreet GPU when both are present. High Sierra and newer will show both graphics services from within About This Mac

Thanks Dan for your detailed explanation.
I hope a predictive app will be available for user to help estimate the remaining serviceable years of a computer.
Given big data is such a popular topic for past ten years, why no such predictive app is available from the computer repair and maintenance industry.
