The Radeon R7 M340 was a mobile graphics chip by AMD, launched on May 5th, 2015. Built on the 28 nm process, and based on the Meso graphics processor, in its Meso PRO variant, the chip supports DirectX 12. This ensures that all modern games will run on Radeon R7 M340. The Meso graphics processor is an average sized chip with a die area of 125 mm² and 1,550 million transistors. Unlike the fully unlocked Radeon R7 A360, which uses the same GPU but has all 384 shaders enabled, AMD has disabled some shading units on the Radeon R7 M340 to reach the product's target shader count. It features 320 shading units, 20 texture mapping units, and 8 ROPs. AMD has paired 2,048 MB DDR3 memory with the Radeon R7 M340, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 943 MHz, which can be boosted up to 1021 MHz, memory is running at 1000 MHz.
Its power draw is not exactly known. This device has no display connectivity, as it is not designed to have monitors connected to it. Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device. Radeon R7 M340 is connected to the rest of the system using a PCI-Express 3.0 x8 interface.
