Performance Rating

The Radeon 540X Mobile was a mobile graphics chip by AMD, launched on February 11th, 2019. Built on the 14 nm process, and based on the Polaris 23 graphics processor, in its Polaris 23 MXL variant, the chip supports DirectX 12. This ensures that all modern games will run on Radeon 540X Mobile. The Polaris 23 graphics processor is an average sized chip with a die area of 103 mm² and 2,200 million transistors. Unlike the fully unlocked Radeon RX 640 OEM, which uses the same GPU but has all 640 shaders enabled, AMD has disabled some shading units on the Radeon 540X Mobile to reach the product's target shader count. It features 512 shading units, 32 texture mapping units, and 16 ROPs. AMD has paired 2,048 MB GDDR5 memory with the Radeon 540X Mobile, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 980 MHz, which can be boosted up to 1095 MHz, memory is running at 1000 MHz (4 Gbps effective).
