The Apple iMac Pro will come with two different versions of AMD’s Radeon Vega GPU
It looks like Apple’s upcoming iMac Pro will be coming with one of two different versions of AMD’s Radeon Vega GPU, coming with either with 8GB of HBM2 memory and 3584 stream processors or 16GB of HBM2 and 4096 stream processors.
Strangely, these are the same core counts as AMD’s old Fiji-based R9 Fury and R9 Fury X GPUs and suggests that one of AMD’s lower end RX Vega counterparts will come with 12.5% fewer stream processors. At this time it is unknown if the memory on the lower end 8GB Radeon Vega GPU will run at different speeds than the higher-end 16GB variant.
Apple lists the Radeon Vega GPU in this system as running with 11 TFLOPs of single precision performance, though at this time it is unknown which Radeon Vega variant will run with this level of performance.
