Performance Rating

The Radeon HD 8670M was a mobile graphics chip by AMD, launched on March 1st, 2013. Built on the 28 nm process, and based on the Mars graphics processor, in its Mars S3 XT variant, the chip supports DirectX 12. Even though it supports DirectX 12, the feature level is only 11_1, which can be problematic with newer DirectX 12 titles. The Mars graphics processor is a relatively small chip with a die area of only 77 mm² and 950 million transistors. It features 384 shading units, 24 texture mapping units, and 8 ROPs. AMD has paired 1,024 MB DDR3 memory with the Radeon HD 8670M, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 775 MHz, which can be boosted up to 825 MHz, memory is running at 900 MHz.
