AMD Radeon RX 7900M performance debut: Alienware m18 R1 laptop review
AMD Ryzen 9 7945HX | AMD Radeon RX 7900M | 18.00" | 3.9 kg
The AMD Radeon RX 7900M is a mobile upper high-end graphics card based on the Navi 31 chip (RDNA 3 architecture) manufactured in 5nm. It features 4,608 cores (72 CUs - compute units) and 16 GB of fast GDDR6 graphics memory connected with a 256 Bit memory bus. The chip also includes 64 MB Infinity Cache. The clock speed of the cores will depend on the laptop according to AMD. The specified game clock speed is 1825 MHz (most likely at 180 W TGP).
AMD compares the performance to the mobile RTX 4080 and shows a number of games where the 7900M is on average 7% faster. Raytracing is supported in hardware, but usually slower than the Nvidia counterpart. Nvidia also has the advantage of DLSS support in selected games.
The Navi 31 chip is manufactured at TSMC in the current 5nm process. The power consumption (TGP) is specified at 160 to 180 Watt (200 Watt including SmartShift from the CPU).
