AMD obviously voiced its support for DirectX and was happy to say that all Radeon GPUs powered by its latest Graphics Core Next (GCN) architecture will support DirectX 12.

AMD Gains Significant Market Share in Q2 2016

by Ryan Shrout |

Over the last couple of quarters we have seen AMD gain in this space, and keeping in mind that Q2 2016 does not include sales of AMD's new Polaris-based graphics cards like the Radeon RX 480, the jump to 29.9% is a big move for the company.
I recently did some benchmarking with triple 4K monitors running a native resolution of 11,520 x 2160, and I didn't expect the results that I did with the new Titan X. The new GDDR5X-based Titan X is around 50% faster than the GTX 1080, and faster again when we look at the last-gen Titan X. AMD's HBM1-powered Fury X is left in the new Titan X's dust, in a big way, mostly because it's limited by its 4GB framebuffer.
There were tactics used that HBM1 and the 4096-bit memory bus (compared to 512-bit on the Radeon R9 390X) were able to fetch what it needed faster and that there was delta color compression, it would beat everything else on the market - at least, that's what the world expected.

AMD Releases Radeon Software Crimson Edition 16.5.2 Beta

by Scott Michaud |

NVIDIA's Game Ready drivers didn't strive for WHQL certification until just recently, and, even then, WHQL certification doesn't mean what it used to.
If you play Battleborn, which launched on May 3rd, then AMD has added a new CrossFire profile for that game.
