While it might sound interesting, the entire new M300 series lineup, which includes the Radeon R9 M375, Radeon R7 M360 and the Radeon R5 M330, is pretty much based on rebrands of the existing M200 series lineup, just with a higher clocks. To make this even worse, the entire "new" M300 series graphics for notebook lineup is based on GCN 1.0 architecture.

To be fair, the new M300 series graphics for notebook lineup stars with Radeon R9 M375, which suggest that we might see more products in near future which could be based on some newer GPUs.

The flagship in the new M300 series is the R9 M375, which is pretty much a version of the previously available R9 M270/M260. Based on AMD's 28nm Cape Verde GPU, it packs 640 Stream Processors, 40 TMUs and 16 ROPs. It will come with up to 4GB of DDR3 memory paired up with a 128-bit memory interface and end up clocked at up to 1015MHz for the GPU and 2.2GHz for memory. The R7 M360 is a version of R7 M270/M260 and based on Oland GPU with 384 Stream Processors. It also works at up to 1015MHz for the GPU but packs up to 4GB of 2.0GHz clocked DDR3 memory paired up with a 64-bit memory interface.

The last is the R5 M330, a version of the R5 M255 GPU also based on Oland GPU but with 320 Stream Processors. It will work at up to 1030MHz and pack up to 4GB of 2.0GHz clocked DDR3 memory paired up with a 64-bit memory interface.

AMD was quite keen to note that new GPUs will feature refined efficiency and power management, support for DirectX 12 and Dual Graphics capabilities with A-Series APUs and judging by specifications, these will need a lot of help from APU graphics in order to get a playable frame rate on even some older games.

AMD also said that systems based on the "new" M300 series mobile GPUs should already be available from Alienware, Dell, HP, Lenovo and Toshiba.
