The Radeon R5 M330 is a graphics card by AMD, launched in May 2015. Built on the 28 nm process, and based on the Exo graphics processor, in its Exo PRO variant, the card supports DirectX 12.0. The Exo graphics processor is a relatively small chip with a die area of only 77 mm² and 1,040 million transistors. It features 320 shading units, 20 texture mapping units and 8 ROPs. AMD has placed 2,048 MB DDR3 memory on the card, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 955 MHz, which can be boosted up to 1030 MHz, memory is running at 900 MHz.
Being a igp card, the AMD Radeon R5 M330 does not require any additional power connector, its power draw is rated at 18 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Radeon R5 M330 is connected to the rest of the system using a PCI-Express 3.0 x8 interface.
