AMD has officially introduced today the Radeon Pro Vega, a powerful next generation professional graphics card that will power Apple’s new iMac pro system.
AMD Vega 10 Die Shot Detailed
Before we get back to AMD’s Radeon Pro Vega, let’s first discuss what sits at the heart of every Radeon Pro Vega graphics cards and that’s the Vega 10 GPU. The very same GPU that will power AMD’s upcoming Radeon Vega Frontier Edition and Radeon RX Vega graphics cards.
The Vega 10 GPU is significantly larger than the Polaris 10/20 chips that the RX 480 and RX 580 are based on. It features 256 texture mapping units and 64 next generation Vega compute units arranged in two islets, each housing two compute engines. Every compute engine includes two distinct compute clusters. Each of those clusters features 512 stream processors and 32 texture mapping units. The chip in its entirety has a total of 4096 stream processors and 256 texture mapping units.
On the front-end side of things there are 64 render output units that make up 16 distinct render back-ends that connect to the 2048-bit wide-IO HBM2 memory interface. The whole Vega 10 die sits on an interposer and is stacked in a 2.5D fashion with two HBM2 stacks. Every stack can be configured with up to 8 GB of memory for a total of 16 gigabytes of memory for both stacks.
