The Radeon E6465 is a graphics card by AMD, launched in September 2015. Built on the 40 nm process, and based on the Caicos graphics processor, the card supports DirectX 11.2. The Caicos graphics processor is a relatively small chip with a die area of only 67 mm² and 370 million transistors. It features 160 shading units, 8 texture mapping units and 4 ROPs. AMD has placed 2,048 MB GDDR5 memory on the card, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 600 MHz, memory is running at 800 MHz.
Being a single-slot card, the AMD Radeon E6465 does not require any additional power connector, its power draw is rated at 25 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Radeon E6465 is connected to the rest of the system using a PCI-Express 2.0 x16 interface.
