AMD announces Radeon Pro Vega 64 and Radeon Pro Vega 56 in Apple Imac Pro

In connection with this year’s WWDC, Apple presented a number of new products, including the Imac Pro, which is equipped with a 5K screen and the latest technology from both Intel and AMD. On the processor front, up to 18 cores from Intel’s processor family Skylake-EP are noticeable, while the graphics part is based on AMD’s architecture Vega.

The product page for Imac Pro states that the computer will be equipped with a Radeon Pro Vega 56 with 8 GB HBM2 memory, and that it can also be configured with more powerful Pro Vega 64 with 16 GB HBM2. The performance stated is 22 TFLOPS at half precision (FP16) or 11 TFLOPS at full precision (FP32), but with which of the two graphics cards it is not clear.

What makes the announcement interesting are the names, which are believed to allude to the number of calculation units for each graphics card. Radeon Pro Vega 64 gets full-scale Vega 10 with 64 computing units or 4,096 stream processors, while Radeon Pro Vega 56 goes down to 56 computing units or 3,584 stream processors.

It is already known that Vega 10, at least on paper, will be very similar to its predecessor Fiji, which is used in the Radeon R9 Fury X and R9 Fury. The similarities continue with the Radeon Pro Vega variants, where the scaled-down Pro Vega 56 has as many computing units as the R9 Fury.

As Apple’s Imac Pro contains non-launched processors from Intel and AMD’s Vega, the launch of the computer will not take place until December.
