AMD Radeon RX 640

AMD Radeon RX 640

The AMD Radeon RX 640 is mobile mid-range graphics card for laptops based on the Polaris architecture. It features 640 shaders (10 CUs) or 512 shaders (8 CUs) with different clock speeds. Compared to the older RX 550(X), the RX 640 seems to offer only half of the memory bandwidth (64 Bit memory bus instead of 128 Bit).

The performance should be slightly lower than the old RX 550 and therefore a Nvidia GeForce MX150. Only low demanding games are therefore playable with the GPU.
