AMD Radeon Pro Vega has been made official by AMD today and the upcoming AMD Radeon Pro Vega 64 and Vega 56 GPUs will be powering the upcoming iMac Pro desktops. These are professional GPUs like the Volta GPUs that were announced by Nvidia recently. At the heart of these GPUs is AMD Vega 10 the same GPU architecture that will be powering the Radeon Vega Frontier Edition.
This is also the same GPU architecture that will be powering the upcoming AMD Radeon RX Vega branded gaming GPUs that will be announced later this month. It is important to note here that the AMD Vega 10 GPU is bigger than Polaris 11 or 12. The GPU features 256 texture mapping units, as well as, 64 Vega compute units that are arranged in islets.
Furthermore, each of these compute engines comprises of two distinct compute clusters and each cluster is composed of 512 stream processors and 32 texture mapping units. That can get a bit tricky to wrap your head around but the bottom line is that you are getting 4096 stream processors and 256 texture mapping units.
Vega 10 die is made up of 2 HBM2 stacks and each stack can consist of 8 GB of memory which adds up to a total of 16 GB of HBM2 memory. You can learn more about AMD Vega architecture here. Talking about the graphics cards that will be powering the upcoming iMac Pros we have the AMD Radeon Pro Vega 64 and Vega 56 GPUs.
The AMD Radeon Pro Vega 64 is not an option that will be standard but users can choose to upgrade to this variant. The GPU features 64 compute units and 16GB of HBM2 memory. The Vega 56 GPUs will be the ones that come as standard and these are cut down versions so they only feature 56 compute units. It will have 3584 GCN stream processors.
The AMD Radeon Pro Vega 64 is expected to provide 22 TFLOPS of graphics horsepower using 400GB/S of memory bandwidth. The key features of the upcoming Vega architecture are as follows:
- 4x Power Efficiency
- 2x Peak Throughput/Performance Per Clock
- High Bandwidth Cache
- 2x Bandwidth per pin
- 8x Capacity Per stack (2nd Generation High Bandwidth Memory)
- 512TB Virtual Address Space
- Next Generation Compute Engine
- Next Generation Pixel Engine
- Next Generation Compute Unit optimized for higher clock speeds
- Rapid Packed Math
- Draw Stream Binning Rasterizer
- Primitive Shaders
