An update from Linux has unveiled more details about the upcoming AMD Vega graphics card and it sounds really powerful according to HotHardware. The Linux direct rendering manager (DRM) update showed that a Vega GPU will be equipped with 64 next-generation compute units, resulting in 4,096 stream processors. For comparison sake, the recently released AMD Radeon RX 580 comes with 36 computing units and 2304 stream processors, making the Vega almost two times more powerful than the 580.
When it comes to teraflops, the Vega will consist of 12.5 teraflops compared to the RX 580 which has 6.2 teraflops supporting the double in power. Another big change is the memory structure, as Vega will be using second generation high-bandwidth memory (HBM2) instead of GDDR5 which is being used in conventional graphic cards from Nvidia and Radeon. The benefits of HMB2 is the ability to achieve higher bandwidth, use less power and is physically compact since the dies are stacked on top of each other.
There were also leaked results where a Vega based GPU was running on 3DMark benchmark Time Spy 1.0 and scored a 5721, for comparison sake, the Nvidia GTX 1070 scored 5699 and the GTX 1080 scored 7152 but it is unsure if this is the mid range or high range GPU of the Vega family. Stay tuned as we will update you when more information surfaces.
