well ive seen what volta has to offer theoretically. I understand the architecture and how it works...pascal x3 throughput. AMD have added logic to vega, so it will become the most efficient gpu ever made. it looks like the card will be on par with the 1080ti, and titan xp.

AMD claims that Vega’s high-bandwidth (HBM) cache controller has been rated to improve maximum frame rates by 50% and minimum frame rates by 100% over the previous generation with GDDR5. In
an interview at GDC, AMD further explained that this tool increases effective memory size by mapping some into system RAM and smartly storing data on local memory.
We also know that the highest-end Vega GPU will contain the same amount of geometry engines for rendering polygons as the previous generation. However, these chips will be able to handle more than twice as many polygons per clock cycle, at 11, as the R9 Fury X’s four per clock.
This era of Vega GPUs will also ditch GDDR5 memory altogether for a new format known as HBM2, or high-bandwidth memory. AMD believes this decision will reduce the footprint of Vega graphics by 50%.
To that end, Vega chips will be more equipped to handle compute tasks than ever – specifically 8-bit, 16-bit, 32-bit or 64-bit operations in each clock cycle – the benefits of which will extend beyond video games.
Finally, AMD’s new Pixel engine will debut in Vega, now moved to a client of the GPU’s L2 memory cache. This will enable it handle graphics workloads which perform frequent read-after-write operations with less overhead on the rest of the GPU.

There’s 4096 so-called ‘stream processors’, which do the majority of the grunt work on AMD graphics cards versus the 2304 on the RX 580. Overall performance is rated at 12.5TFLOPS (trillion floating point operations per second; a basic horsepower measurement) versus 5.8 on the
RX 580.
In addition, we’re looking at 8GB Of HBM2 (High-Bandwidth Memory) with a super-wide 2048-bit bus.
. I am not going to hold my breath though.
