5.9 Out of 10

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 Announced

by Scott Michaud |

I wonder what this means for the Tesla line, and whether we will see a variant of Maxwell with a large boost in 64-bit performance, or if that line will be in an awkward place until Pascal.
The memory, but not the cache, is capable of ECC (error-correction) for enterprises who do not want a stray photon to mess up their computation.
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 |
www.anandtech.com
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.
While we already did a drop, scratch and water test to see if the smartphone could sustain a few hits here and there; iFixit’s One M8 teardown would show you what to expect realistically when you have a broken or damaged HTC One M8.
IFixit also notes that the repair work is made harder by the use of copious amounts of tape, adhesive, and copper shielding.
