Radeon HD 3850 X3 

Released April, 2008
  • 669 MHz
  • 1.5 GB GDDR3

The core clock for the reference model are maintained at 1126 MHz core and 1216 MHz boost while the memory is clocked at 7 GHz effective clock speed pumping out 224.4 GB/s worth of memory bandwidth.

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.

What's Asynchronous Compute? 3DMark Time Spy Controversy

by Scott Michaud |
www.pcper.com
A game developer will tend to avoid a performance-reducing feature on certain GPUs.
This is a trivial example, because I believe every Vulkan- or DirectX 12-supporting GPU can do it, even the mobile ones.
While other companies have faltered and faded, Futuremark continues to push forward with new benchmarks and capabilities in an attempt to maintain a modern way to compare performance across platforms with standardized tests.
This does mean the frame rates you see on the screen are not indicative of any kind of Time Spy score.
