AMD Radeon R7 M340

The AMD Radeon R7 M340 is a low-end dedicated graphics card for laptops. It could be based on a new derivative of the Tonga chip and therefore support DirectX 12, Vulkan and FreeSync. According to our informations the chip will be clocked at 1021 MHz and featuring 5 compute cores. That would turn out to be slower than the R5 M335 and M330 (but faster than the M320). The gaming performance should be therefore somewhere in the ballpark of the old Radeon R5 M255 (see for gaming benchmarks).
