Hey guys,
I realise this may be a silly question to ask but here it goes.
Do any of you guys happen to know what the GPU memory bandwidth is on each 2012 iMac 21.5" and 27"?
You may think that I should just look on the NVIDIA website. However there seems to be a discrepancy between the specs the of the mobile GPUs included in the iMacs and what's on NVIDIA's website. I don't mean in terms of the GPU name just the bandwidth. I search GPU Boss and it says, for instance that the GT 640m, included on the entry leve iMac has a memory bandwidth of 40GB/s and the NVIDIAwebsite says up to 64GB/s, depending the the type of GPU memory (DDR3 or GDDR5). I'm kind of confused as to what it is.
The reason I'm interested in the GPU's memory bandwidth is because it's one of the many specs that determins how fast the GPU is.
Anyway that'sall. Any help any of you can give would be great.
I did have a thought. if any of you happen to run Windows on your 2012 iMacs you can use a tool called GPUID, as oppose to the CPUID untility, and that would give you the correct specs on your GPU's memory bandwidth.
