The Radeon R5 M320 was a mobile graphics chip by AMD, launched on May 5th, 2015. Built on the 28 nm process, and based on the Jet graphics processor, in its Jet PRO 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 Jet graphics processor is a relatively small chip with a die area of only 56 mm² and 690 million transistors. Unlike the fully unlocked Radeon R6 M335DX, which uses the same GPU but has all 384 shaders enabled, AMD has disabled some shading units on the Radeon R5 M320 to reach the product's target shader count. It features 320 shading units, 20 texture mapping units, and 8 ROPs. AMD has paired 4 GB DDR3 memory with the Radeon R5 M320, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 780 MHz, which can be boosted up to 855 MHz, memory is running at 1000 MHz.
Its power draw is not exactly known. This device has no display connectivity, as it is not designed to have monitors connected to it. Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device. Radeon R5 M320 is connected to the rest of the system using a PCI-Express 3.0 x8 interface.
