Report: NVIDIA Preparing GeForce GTX 980MX and 970MX Mobile GPUs

by Sebastian Peak |
Memory speed and bandwidth will reportedly be identical to the GTX 980M at 5000 MHz and 160 GB/s respectively, with both GPUs using a 256-bit memory bus.
NVIDIA is reportedly preparing faster mobile GPUs based on Maxwell, with a GTX 980MX and 970MX on the way.

Apple Initiates Video Repair Program for 2011-2013 MacBook Pros

by Ryan Smith |
Namely, while the iMac used its dGPU exclusively the MacBook Pros all used switchable graphics, which means that the MacBook Pros are often being driven by their iGPU rather than their dGPU.
While the 2011 iMac and MacBook Pros use different GPUs, both systems use GPUs from AMD’s Radeon HD 6000M series, with the iMac using the higher-end 6970M while the MacBook Pros used the 6490M, 6750M, and 6770M GPUs.

Nvidia Geforce Mobility GTX 870MX Spotted – A Possible High End Maxwell Variant

by Syed Muhammad Usman Pirzada |
There are two probable scenarios on what happened, either we are getting the high end Maxwell mobility as a counter to the AMD R9 M295X or this is just a clerical typo.
Now if these are indeed Maxwell chips then we are almost certainly looking at 28nm Maxwell, since latest reports indicated that the 20nm node is not mature enough for the fabrication of high performance ASICs (GPUs in this case).
Micron’s 128Gb MLC NAND Flash memory devices are targeted at applications like consumer SSDs, removable storage (USB drives and Flash cards), tablets, ultrathin devices, mobile handsets and data center cloud storage.
The new 128Gb NAND Flash memory provides the greatest number of bits per square millimeter and lowest cost of any MLC device in existence.
