Apple has taken the iMac to a whole new level. Pros wanted the Cupertino company to build a killer iMac. And Apple went all in. An iMac packed with the most staggeringly powerful collection of workstation-class graphics, processors, storage, memory and I/O of any Mac ever. An iMac with 18 cores. And Turbo Boost speeds up to 4.5GHz – to deliver lightning speeds for rendering files, editing 4K video, real-time audio effects and more. Above and beyond these specs there’s something even more marvelous – the Vega graphics.

iMac Pro’s AMD Vega 56 and Vega 64 detailed

AMD Vega 56 and Vega 64 – the GPU’s that will be in the iMac Pro – have now been detailed, thanks to AMD’s Linux driver update. When 32 bits precision isn’t really a necessity, the cards can handle twice as much data in each register as the previous cards. As for the specs, the Vega Pro 64 has, as the name suggests, 64 compute units. It packs in 4096 stream processors and 16GB HBM2 RAM. Vega Pro 64 is capable of FP32 single-precision calculations at 13tflop with FP16 at 25 tflop.

AMD Vega Pro 56 is also a beast in itself. Featuring 56 compute units and 3584 stream processors, Vega Pro 56 packs in 8GB HBM2 RAM at 400GB/s data. Single precision calculations stand at 11tlfops while half-precision calculations can reach a peak of 22tflops.

The Radeon Pro Vega is over three times faster than any previous iMac GPU and packs the power of a double-wide graphics card into a single chip. This translates directly to higher frame rates for Virtual Reality applications, real-time 3D rendering, more lifelike special effects and gameplay at max settings. On-package HBM2 replaces the external VRAM, so the GPU can essentially fetch data up to a whopping 400GB/s.
