Radeon HD 7670A 

Released January, 2012
  • 600 MHz
  • 1 GB GDDR5

The A8-4500M takes a pretty major chunk out of the GPU (one third of the GPU cores are gone along with a slight drop in maximum clock speed) while maintaining roughly 80% of the CPU performance, so it can fit into slightly cheaper laptops but will likely drop gaming performance from “moderate” to “light.

Similarly the move to a more efficient VLIW4 GPU architecture and additional tuning helped give AMD a boost in GPU performance without increasing die size.

AMD will show up in iMac 27 and a few more

by Fuad Abazovic |

This is a significant win for AMD, but the real winner is Intel since most Apple notebooks will continue using integrated Intel HD or Iris graphics.
We are not sure what Nvidia did to upset Apple, but this round of devices will be powered either by Intel integrated graphics or AMD discrete graphics.

AMD Releases FreeSync Information as a FAQ

by Scott Michaud |
www.pcper.com
Dynamic refresh rates have two main purposes: save power by only forcing the monitor to refresh when a new frame is available, and increase animation smoothness by synchronizing to draw rates (rather than "catching the next bus" at 16.67ms, on the 16.67ms, for 60 Hz monitors).
For instance, it clarifies the distinction between DisplayPort Adaptive-Sync and Project FreeSync.
Well, now an enthusiast called K-putt has used a hacked Crysis 3 executable to run the game at 8K — and I’m not being hyperbolic when I say that the resultant screenshots are probably the most beautiful examples of real-time computer-generated graphics that I’ve ever seen.
As you’re probably well aware, ever since Crysis was first released in 2007, it has been the benchmark for graphics card performance and beautiful real-time visuals.
A DDR3-2400 Mhz Dual Ranked RAM was used for the APU to make sure it performed at its best.
The second benchmark is also a well known GPGPU software called Sisoft Sandra GPGPU and though here the Maxwell GPU GTX 750 leads the benchmarks the margin is really not that huge.
