Just as Ryzen made AMD competitive in the top-end processor market for the first time in about a decade, there is an expectation that the company's upcoming Vega launch will do the same in the GPU arena. As leaks become bigger and more frequent leading up to Vega's release, the most recent one gives us a supposed glimpse of Vega's specifications.
In a recent report from a source, some interesting details from a Direct Rendering Manager (DRM) update for Linux that was submitted by AMD were revealed. AMD's Radeon RX Vega is said to feature 64 next gen compute units, each with 64 GCN stream processors. and that gives 4,096 next generation GCN stream processors divided into four divisions, each of that comprises a shader engine.

Interestingly, each 1,024 stream processor shader engine wields two asynchronous compute units, a render back-end, and four texture blocks. In the inside, each of those texture blocks has 16 texture mapping units which give the graphics card a total of 256 TMUs. Also, it supports eight hardware threads.
AMD Radeon RX Vega Specifications Revealed
Reports claim that AMD Radeon RX Vega will be built on the 14nm Vega 10 XT architecture. Alongside, Vega will have 256 Texture Mapping Units and 8GB HBM2 on a 2048-Bit memory interface.
A comparison with Nvidia's GeForce GTX 1080 Ti points out that AMD's effort has a major edge, thanks to a greater number of shaders, as well as more texture mapping units. The GTX 1080 Ti provides around 11.3 TFLOPS and that is a shade lower than this upcoming variant from AMD Radeon RX Vega.
Furthermore, the benchmark and gaming performance could vary intensely from the back of the box specs. On the other note, Radeon RX Vega will surely outperform the GTX 1070 considerably by the time it hits the tech market.
