Radeon HD 7870M 

Released April, 2012
  • 800 MHz
  • 2 GB GDDR5

Intel is so much focused on the power output of the Core M die that they even designed a new PCH known as Broadwell PCH-LP which is focused on power.

Another key enabler of the Core M processor is the use of 2nd generation FIVR and 3DL for power efficiency delivery.
There’s a small section dedicated to the memory and I/O controllers at the bottom of the die while along the right side, we can note the system agent, display engine and memory controller.

AMD Q3 2012 Earnings: $157M Loss; 15% of Workforce To Be Cut

by Ryan Smith |

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In Q3 of 2011 Llano was the biggest factor in AMD turning a profit, but a year later those chips have been superseded by AMD’s new Trinity APU.

AMD Launches HD 7700M, 7800M, and 7900M Mobile GPUs

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).

AMD Launches Radeon 7700M, 7800M, and 7900M Mobile GPUs

by Jarred Walton |

We asked AMD about the removal of PCIe 3.0 support (given both families use Cape Verde, the potential is certainly there), and their response confirmed our suspicions: “The Cape Verde die itself supports PCIe 3; the reason we chose not to include it in our 7700M is because it mostly targets platforms where power saving is king, and the sacrifice (though not huge) in that regard would not have been justified by the small performance gain going from gen 2 to gen 3.
With so-called “power viruses” like OCCT and Furmark, users started encountering issues with GPUs exceeding those limits, and the results ranged from crashing to even failed hardware.
