The AMD Radeon R7 M340 is a low-end graphics card used for entry-level laptops and it’s based on the so-called Tonga chip so it supports the essential features like DirectX 12, Vulkan and FreeSync.
However, the chip is clocked at 1021 MHz with five compute cores so it should be a tad faster than the R5 M335. And just like its predecessors with the Tonga chip, this one offers 64-bit bus width on a DDR3 VRAM, 320 shading units and it’s produced using a 28nm process.
