Suppliers reportedly preparing the AMD Radeon Pro Vega cards for the iMac Pro

DigiTimes reports that Apple suppliers are preparing the AMD Radeon Pro Vega cards that will power the graphics on the iMac Pro, which is due in December. Buyers will have an option to choose between the Vega 56 or 64, which have 8GB and 16GB of HBM2 memory, respectively, the article adds. 

Mac Pro, with its 27-inch Retina 5K display, next generation Intel Xeon processors up to 18 cores, up to 22 Teraflops of graphics computation, up to 16GB of VRAM, up to 128GB of memory, built-in Ethernet, and support for one billion colors, is the most powerful Mac ever made, says John Ternus, Apple’s vice president of Hardware Engineering. It comes in a new space gray enclosure.

With an all-flash architecture and all-new thermal design, iMac Pro delivers up to 80% more cooling capacity in the same thin iMac design, says Ternus. It will come with the new Radeon Pro Vega GPU, the most advanced graphics ever in a Mac. 

The iMac Pro with the Vega GPU delivers up to 11 Teraflops of single-precision compute power for real-time 3D rendering and immersive, high frame rate VR. For half-precision computation, ideal for machine learning, the pro all-in-one delivers up to 22 Teraflops of performance.

The iMac Pro also supports up to 4TB of SSD and up to 128GB of ECC memory, and with four Thunderbolt 3 ports can connect to up to two high-performance RAID arrays and two 5K displays at the same time. Pricing will start at $4,999.
