Radeon HD 6990M 

Released July, 2011
  • 715 MHz
  • 2 GB GDDR5
These chips are still based on Kepler (600-series), but feature more CUDA cores, more memory, a wider memory bus, and faster clockspeeds.

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.

NVIDIA Quadro M6000 Leaks via Deadmau5

by Ryan Shrout |
A quick hunt on Google for the NVIDIA M6000 reveals rumors of it being a GM200-based 12GB graphics card.

Nvidia Maxwell goes mobile with GTX 980M and GTX 970M

by Slobodan Simic |
Despite their same name, mobile GPUs are always way below their desktop counterparts for obvious reasons, and while that might happened before, the new Maxwell 2.0 changes everything and closes the relative performance gap placing the performance of the mobile GTX 980M at around 80 percent of the GTX 980.
Efficiency is quite impressive considering the GPU is still based on the 28nm manufacturing process.
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.

Intel Broadwell Architecture Preview: A Glimpse into Core M

by Ryan Smith |
When it comes to building and configuring Core M, Intel likes to refer to their efforts as the “Fanless Challenge,” reflecting the fact that their biggest goal with Core M is to comfortably get the processor in to 10” tablets under 10mm in thickness that are passively cooled.
The end result no doubt limited what performance optimizations Intel could integrate into Broadwell’s design, but it also functionally reduces power requirements for any given performance level, furthering Intel’s goals in getting Core performance in a mobile device.
