What is the AMD Radeon RX 7900M?
The AMD Radeon RX 7900M is a unique mobile GPU because it uses a multi-chiplet module design, which means that it has two separate GPU dies connected by an interposer. This allows the GPU to achieve higher clock speeds and lower power consumption than a single monolithic die.
The GPU also has 64 MB of Infinity Cache, which is a high-bandwidth cache that reduces memory latency and bandwidth consumption. The AMD Radeon RX 7900M has 4,608 cores (72 CUs – compute units) and 16 GB of fast GDDR6 graphics memory with a 256-bit bus.
The GPU has a base clock of 1825 MHz and a boost clock of 2090 MHz. Its power draw is rated at 180 W maximum. The AMD Radeon RX 7900M supports DirectX 12 Ultimate, which is the latest version of Microsoft’s graphics API that enables features such as hardware-raytracing, variable-rate shading, mesh shaders, and sampler feedback.
The GPU also has dedicated AI acceleration, which enables features such as AMD FidelityFX Super Resolution (FSR), AMD Smart Access Memory (SAM), and AMD SmartShift Technology. These features aim to enhance the gaming performance and visual quality of the GPU.
AMD Radeon shared a post on Twitter:

How Does the AMD Radeon RX 7900M Compare to the Nvidia RTX 4080 Mobile?
The AMD Radeon RX 7900M is a direct competitor to the Nvidia RTX 4080 mobile, which is also a high-end mobile GPU based on the Ampere architecture. The RTX 4080 mobile has 6,144 cores (96 SMs – streaming multiprocessors) and 16 GB of GDDR6 memory with a 256-bit bus.
The GPU has a base clock of 1365 MHz and a boost clock of 1710 MHz. Its power draw is rated at 150 W maximum. The Nvidia RTX 4080 mobile also supports DirectX 12 Ultimate and has dedicated ray-tracing cores and tensor cores for AI acceleration.
The RTX 4080 mobile enables features such as Nvidia DLSS (Deep Learning Super Sampling), Nvidia Reflex, and Nvidia Broadcast. According to AMD, the Radeon RX 7900M delivers up to 30% more performance than the RTX 4080 mobile in popular games at QHD resolution with max settings.
AMD claims that the Radeon RX 7900M can run games such as Cyberpunk 2077, Battlefield V, and Resident Evil Village at over 60 FPS with ray-tracing enabled.
However, these claims are based on AMD’s own testing and benchmarks, and may not reflect the real-world performance of the GPU in different scenarios and configurations. Moreover, Nvidia may have an advantage in terms of driver support and optimization for some games and applications.
