Performance Rating

The Radeon HD 8870M was a mobile graphics chip by AMD, launched on April 1st, 2013. Built on the 28 nm process, and based on the Venus graphics processor, in its Venus 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 Venus graphics processor is an average sized chip with a die area of 123 mm² and 1,500 million transistors. It features 640 shading units, 40 texture mapping units, and 16 ROPs. AMD has paired 2,048 MB GDDR5 memory with the Radeon HD 8870M, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 725 MHz, which can be boosted up to 775 MHz, memory is running at 1125 MHz (4.5 Gbps effective).
