Performance Rating

The Radeon R5 M420 was a mobile graphics chip by AMD, launched on May 15th, 2016. 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 M420 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 M420, 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 850 MHz, memory is running at 1000 MHz.
