Radeon HD 6830M 

Released January, 2011
  • 575 MHz
  • 1 GB DDR3

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.

This is similar to Ivy Bridge (4%-6%), though at this stage in the game Intel is not talking about expected clockspeeds or the resulting overall performance improvement.

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.
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.
That means there are a lot of people out there looking for information about the performance they can expect on various harware configurations with Diablo III.
We did also run some tests to an external monitor at 1920x1080 with "low" presets and AA disabled - both are reported in the video below.
