The recent specifications published by Apple for its new iMac Pro 2017 reveal certain interesting aspects for upcoming AMD Vega Pro lineup. It seems like AMD may continue its 3584 cores design with its upcoming Vega GPUs.
The new data from Apple iMac Pro reveals that it comes packed in two different version of AMD Vega graphics card unit. One of them is AMD Radeon Pro Vega 56 with 8GB of HBM2 memory and the other AMD Radeon Pro Vega 64 with 16GB of HBM2 memory.
The numbers 56 and 64 are likely referring to the NCU count, which means AMD may adopt the same design scheme the one they did with Radeon R9 Fury. Radeon R9 Fury had either 3582 cores (56 CUs) or 4096 cores (64 CUs). This is mere a speculation, as AMD has not charted any information regarding the roadmap of Vega Pro CUs.
However, the available information regarding two Radeon Vega Pro versions in new iMac Pro cannot be over sighted.
The hardware of Apple iMac Pro 2017 comes in different versions, divided on basis of core count and memory capacity of AMD Vega GPU. The lower version includes CPUs with either 8 or 10 cores and the highest version will have a whooping 18 core count. Moreover, the lower version will have 8GB of HBM2 memory or 16GB HBM2 memory. In short, the new Apple iMac Pro 2017 comes packed with plenty of combinations.
