Radeon HD 5770 X2 

Released October, 2010
  • 850 MHz
  • 2 GB GDDR5
Some of the CPU workload has been distributed to other threads, other aspects of the CPU workload have been eliminated entirely.

With the Xbox One now being based on an x86 architecture, and the operating system sounding suspiciously similar to Windows 8, it should be very easy to port games to Windows 8.1.

Rumor: NVIDIA's Next GPU Called GTX 1080, Uses GDDR5X

by Sebastian Peak |
Pascal is the name we've all being hearing about, and along with this next-gen core we've been expecting HBM2 (second-gen High Bandwidth Memory).
We are expecting news of the next NVIDIA graphics card this spring, and as usual whenever an announcement is imminent we have started seeing some rumors about the next GeForce card.

AMD Projects Decreased Revenue by 8% for Q2 2015

Q3 will count two of the launch months for Windows 10, which will likely include a bunch of new and interesting devices and aligns well with back to school season.
When it comes to the GPU-based head tracking, AMD is using its GCN architecture to "ensure [the] most up-to-date head tracking inputs are used for VR rendering and image/time warp.
AMD was quick to point out that its GCN architecture, which is found in everything from tablets right up to the latest and greatest gaming PCs, is ready for DirectX 12.

Most DirectX 12 features won’t require a new graphics card

by Ryan Whitwam |
While past updates to DirectX have focused on new rendering effects like tessellation and more realistic shaders, DirectX 12 is an attempt to dramatically reduce driver overhead and get PC gaming closer to console levels of efficiency by learning some lessons from AMD’s Mantle API.
Consoles have very narrow hardware profiles, but the hardware abstraction layer in DirectX slows things down.
