It will work at 823MHz+ GPU clock and feasture 4GB of GDDR5 memory clocked at 5GHz and paired up with a 256-bit memory interface that add up to 160GB/s of memory bandwidth.

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.
Overclocking the memory and GPU clock speeds on an AMD APU can greatly improve gaming performance - it is known.
Clearly that can make the AMD Kaveri APU an even more potent gaming platform if you are willing to shell out for the high speed memory.
This also suggests that faster memory speeds would result in better overall performance from the graphics card.
The Kaveri APU can scale down to server platforms, from the high-end desktop PCs all the way to notebooks, servers and embedded applications.
AMD Radeon Memory enables top performance and maximum value for a boost in entertainment and gaming experiences.
With 12 Compute Cores (4 CPU + 8 GPU) featuring AMD Radeon R7 Graphics and exclusive features like AMD TrueAudio Technology for immersive audio, it can take on Battlefield 4 or just about anything else you throw at it.
