AMD Radeon R9 M380 vs AMD Radeon R9 M395X vs AMD Radeon R9 M395
AMD Radeon R9 M380► remove
The AMD Radeon R9 M380 is a dedicated mid-range graphics card for laptops. It is based on a 28nm GCN core with 12 compute units and a GDDR5 memory controller. Despite the similar name, the Radeon R7 M380 is a much slower as it features only 10 compute units and DDR3 memory.
Features of the R9-M380 include video decoding for MPEG-4 AVC/H.264, VC-1, MPEG-2, and Flash directly by the AMD GPU. Multi-View Codec (MVC) and MPEG-4 part 2 (DivX, xVid) HD videos are compatible as well.
The R9 series also supports automatic graphics switching between the integrated GPU and discrete GPU. Called Enduro, the technology supersedes AMD's Dynamic Switchable Graphics and is similar to Nvidia's Optimus. Furthermore, the M380 can directly support multiple monitors using Eyefinity Technology if Enduro is disabled.
Other features include ZeroCore to reduce the power consumption when the display is turned off and Power Gating to power down areas of the chip that are not used.
The integrated HD audio processor is able to transmit HD Audio (TrueHD or DTS Master Audio) over HDMI and DisplayPort (e.g., for Blu-Ray videos). Additionally, it allows audio output simultaneously and in parallel to multiple devices with the new Discrete Digital Multipoint Audio (DDMA) feature.

The AMD Radeon R9 M395X is a mobile high-end graphics card based on the Tonga chip (3rd generation of GCN). It uses all of the 2048 shader cores (32 compute units) as the previous generation R9 M295X but features a slightly higher core clock (+60 MHz). Therefore, the performance should be on a level with the R9 M295X (see for benchmarks).

The AMD Radeon R9 M395 is a high-end mobile graphics card that can be found in the 2015 iMac 5K 27-inch. It offers 1792 shader cores (28 compute cores) clocked at 834 MHz. The 2 GB GDDR5 dedicated graphics memory is connected with a 256 Bit bus at 1365 (= 5460 effective) MHz.
The performance should be between the older Radeon R9 M295X and the Desktop Radeon R7 370. Therefore, demanding Windows games like Fallout 4 or Call of Duty: Black Ops 3 should run in maximum details at 1920x1080 (with no headroom).
