AMD Radeon R9 M270

The AMD Radeon R9 M270 is an upper mid-range, DirectX 12-capable graphics card for notebooks. It is manufactured in 28nm and based on the GCN (Graphics Core Next) architecture from AMD. The R9 M270 is probably just a renamed Radeon HD 8870M with 640 shader units (725 - 775 MHz) and up to 4 GB of GDDR5 memory (1125 MHz / 4500 MHz effective).

According to this information (not yet officially confirmed), the performance of the R9 M270 should exactly match its predecessor. Thus, the GPU should be somewhat slower than a Nvidia GeForce GTX 760M

Please note: The technical specifications and clock rates are based on speculation and have not been verified by the manufacturer. The R9 M270 has been first seen in the Lenovo Y40.
