The Radeon R9 M395 Mac Edition is a graphics card by AMD, launched in May 2015. Built on the 28 nm process, and based on the Grenada graphics processor, in its Grenada PRO variant, the card supports DirectX 12.0. The Grenada graphics processor is a large chip with a die area of 438 mm² and 6,200 million transistors. Unlike the fully unlocked Radeon R9 390X, which uses the same GPU but has all 2816 shaders enabled, AMD has disabled some shading units on the Radeon R9 M395 Mac Edition to reach the product's target shader count. It features 1792 shading units, 112 texture mapping units and 32 ROPs. AMD has placed 4,096 MB GDDR5 memory on the card, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 834 MHz, memory is running at 1365 MHz.
Being a mxm module card, the AMD Radeon R9 M395 Mac Edition does not require any additional power connector, its power draw is rated at 250 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it.
