by Doug-Crowthers (Apr, 2012)The Enduro technology should come in very handy for mobile users concern with power consumption.
Features Key features of the Radeon HD 7490M
memory bandwidth Rate at which data can be read from or stored in onboard memory
pixel rate Number of pixels a graphics card can render to the screen every second
texture rate Speed at which a graphics card can perform texture mapping
floating point performance How fast the gpu can crunch numbers
shading units Subcomponents of the gpu, these run in parallel to enable fast pixel shading
texture mapping units Built into each gpu, these resize and rotate bitmaps for texturing scenes

The 760M and 765M both use 768 CUDA cores, but the 765M is clocked almost 200MHz faster.
The RAM and core are connected via a 256-bit interface.

Unfortunately as we’ve seen time and time again with AMD, while their Graphics division can consistently turn a small profit, at only 1/3rd the revenue of their Computing Solutions division it’s not nearly large enough to offset the losses AMD has run there.
In Q3 of 2011 Llano was the biggest factor in AMD turning a profit, but a year later those chips have been superseded by AMD’s new Trinity APU.

Combined with AMD's ZeroCore and Power Gating technology, the HD 7000M series is setting up to be a very power efficient platform.
The third chart shows the HD 7000M's performance increases you can see over the CPU alone, when taking into account GPGPU and Compute (based on ComputeMark benchmark).
