Radeon HD 8850M 

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.

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.

The GTX 780M is not quite the mobile equivalent to the desktop GTX 680, but NVIDIA is matching it up against AMD's 8970M GPU and claims that it can run games like Sleeping Dogs, Assassins Creed 3, and Borderlands 2 at Ultra settings (1080p).

NVIDIA is now adding higher-end mobile GPUs to the 700M family with the GTX 760M, GTX 765M, GTX 770M, and GTX 780M.

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.
