AMD VEGA 10 GPU Specifications Leaked In Driver Documents

The sleuths over at ComputerBase looked into AMD’s latest Linux driver code discovered some Vega 10 goodies in a recent update to the Direct Rendering Manager. It looks like Vega 10 will have 4,096 next generation GCN stream processors that are divided up four ways for a grand total of 1,024 stream processors per shader engine. There are a total of 256 Texture Mapping Units (TMUs), 64 Render Output Units (ROPs) and 8GB of HBM2 memory running on a 2048-bit memory bus. AMD’s upcoming Vega-architecture based GPUs have been designed from scratch with a new compute engine, pixel engine, geometry pipeline and new memory subsystem designed to compliment HMB2 memory. Due to all the architecture changes it is hard to say how this new GPU will perform over AMD’s Polaris or Fiji GPUs.

case CHIP_VEGA10:
adev->gfx.config.max_shader_engines = 4;
adev->gfx.config.max_tile_pipes = 8; //??
adev->gfx.config.max_cu_per_sh = 16;
adev->gfx.config.max_sh_per_se = 1;
adev->gfx.config.max_backends_per_se = 4;
adev->gfx.config.max_texture_channel_caches = 16;
adev->gfx.config.max_gprs = 256;
adev->gfx.config.max_gs_threads = 32;
adev->gfx.config.max_hw_contexts = 8;

In other news, there are reportedly three RX Vega SKUs that will be coming when the new Vega GPU launches sometime this quarter. A forum user over at Guru3D claims that the three Vega 10 device IDs are; 687F:C1, 687F:C2, and 687F:C3. They note that all three have 8GB of HBM2 memory, but there will be a cut down version (maybe a Nano Vega card) and then two full featured versions with one being air cooled and then another being water cooled.

BIG WC = 687F:C3
BIG Air = 687F:C2
VEGA = 687F:C1

Are you ready multiple Vega cards to come to market? With less than 60 days left in Q2 2017, we shouldn’t have to wait much longer to see if RX Vega lives up to the hype that AMD has been building up for months!
