The Radeon RX 7900M is a mobile graphics chip by AMD, launched on October 19th, 2023. Built on the 5 nm process, and based on the Navi 31 graphics processor, in its Navi 31 variant, the chip supports DirectX 12 Ultimate. This ensures that all modern games will run on Radeon RX 7900M. Additionally, the DirectX 12 Ultimate capability guarantees support for hardware-raytracing, variable-rate shading and more, in upcoming video games. The Navi 31 graphics processor is a large chip with a die area of 529 mm² and 57,700 million transistors. Unlike the fully unlocked Radeon RX 7900 XTX, which uses the same GPU but has all 6144 shaders enabled, AMD has disabled some shading units on the Radeon RX 7900M to reach the product's target shader count. It features 4608 shading units, 288 texture mapping units, and 192 ROPs. The card also has 72 raytracing acceleration cores. AMD has paired 16 GB GDDR6 memory with the Radeon RX 7900M, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 1825 MHz, which can be boosted up to 2090 MHz, memory is running at 2250 MHz (18 Gbps effective).
Its power draw is rated at 180 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 7900M is connected to the rest of the system using a PCI-Express 4.0 x16 interface.
