Performance Rating

The Radeon R9 M270X was a mobile graphics chip by AMD, launched on February 5th, 2015. Built on the 28 nm process, and based on the Saturn graphics processor, in its Saturn PRO variant, the chip supports DirectX 12. This ensures that all modern games will run on Radeon R9 M270X. The Saturn graphics processor is an average sized chip with a die area of 160 mm² and 2,080 million transistors. Unlike the fully unlocked Radeon R9 M280X, which uses the same GPU but has all 896 shaders enabled, AMD has disabled some shading units on the Radeon R9 M270X to reach the product's target shader count. It features 768 shading units, 48 texture mapping units, and 16 ROPs. AMD has paired 2,048 MB GDDR5 memory with the Radeon R9 M270X, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 900 MHz, which can be boosted up to 1000 MHz, memory is running at 1375 MHz (5.5 Gbps effective).
