AMD Vega Specs Update: Leak Reveals 8GB HMB2, 4096 Stream Processors, & Over 12 TFLOPs

Just as Ryzen made AMD competitive in the high-end CPU market for the first time in about a decade, there is a hope that the company's upcoming AMD Vega launch will do the same in the GPU sector. The most recent leak regarding the AMD Vega provides a supposed glimpse of upcoming GPU's specifications.

A member of Reddit has extracted some interesting details from a Direct Rendering Manager (DRM) update for Linux which was submitted by AMD. According to the driver package, AMD Radeon RX Vega will have 64 next generation compute units, each with 64 GCN stream processors. That gives it 4,096 next generation GCN stream processors divided into four divisions, each of that comprises a shader engine, according to Hot Hardware.

To break things down, even more, each 1,024 stream processor shader engine wields two asynchronous compute units, a render back-end, and four texture blocks. Within each of those textures, blocks are 16 textures mapping units, which gives the graphics card a total of 256 TMUs. It supports eight hardware threads as well.

The Radeon RX Vega will be having 14nm process node, 4 shader engines, 4,096 stream processors, 12.5 TFLOPS / 25 (FP16) TFLOPS, 64 render output units, 256 texture mapping units, plus 8 hardware threads and 2,048-bit memory interface. The upcoming AMD Radeon RX Vega will also feature, 8GB High Bandwidth Memory 2 (HBM2).

According to Racing Junky, the specs for the AMD Radeon RX 480 graphics card includes, 14nm process node, 4 shader engines, 2,304 stream processors, 5.8 TFLOPS / 5.8 (FP16) TFLOPS, 32 render output units, 144 texture mapping units, 4 hardware threads and 256-bit memory interface. Here there is a big change about memory this card will have 8GB GDDR5 memory in the place of HBM2 memory.

In all probability, the Linux driver points to a higher-end AMD Vega card, one that will compete with NVIDIA's GeForce GTX 1080 or 1080 Ti. It also expected AMD to release lower end SKUs, perhaps with half as much memory. Nothing is set official, of course, but it would make sense for AMD to launch multiple Vega cards that line up against NVIDIA's higher-end Pascal cards, from the GeForce GTX 1070 on up.
