The Radeon RX 6600M is a mobile graphics chip by AMD, launched in February 2021. Built on the 7 nm process, and based on the Navi 23 graphics processor, the chip supports DirectX 12 Ultimate. This ensures that all modern games will run on Radeon RX 6600M. Additionally, the DirectX 12 Ultimate capability guarantees support for hardware-raytracing, variable-rate shading and more, in upcoming video games. The Navi 23 graphics processor is an average sized chip with a die area of 236 mm². Unlike the fully unlocked Radeon RX 6600 XT, which uses the same GPU but has all 2048 shaders enabled, AMD has disabled some shading units on the Radeon RX 6600M to reach the product's target shader count. It features 1792 shading units, 112 texture mapping units, and 64 ROPs. AMD has paired 8 GB GDDR6 memory with the Radeon RX 6600M, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 1489 MHz, which can be boosted up to 2105 MHz, memory is running at 2000 MHz (16 Gbps effective).
Its power draw is rated at 150 W maximum. 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 RX 6600M is connected to the rest of the system using a PCI-Express 4.0 x8 interface.
