Things aren't looking good for AMD with all of these lukewarm rumors on Radeon RX Vega, with the latest purported results of the HBM2-based graphics card barely edging out NVIDIA's GeForce GTX 1070 in 3DMark TimeSpy.

AMD's upcoming Radeon RX Vega seems to have its GPU clocked at 1GHz base, and 1.2GHz boost - at least in reference form. There's 8GB of HBM2 with 512GB/sec of memory bandwidth, and a TDP of 225W. If these results are true, Vega isn't exactly a GTX 1080 killer, let alone a GTX 1080 Ti killer. But then remember that AMD could be under delivering with performance right now, and things will change with tuned drivers and final hardware. Now... this is where things could get interesting: AMD has multiple Vega graphics cards in the pipeline - so this iteration of RX Vega might be the GTX 1070 competitor, while we might see another RX Vega that competes wiht the GTX 1080, and a monster that hopefully dethrones the GTX 1080 Ti. I'm sure we're going to see a fully unleashed Vega graphics card with the 4096-bit memory bus, and its HBM2 memory hitting 1TB/sec - but at what cost?
