AMD recently launched the Radeon RX 7800M GPU, featuring the latest RDNA 3 architecture tailored for gaming laptops. This GPU aims to deliver desktop- and console-level gaming experiences on portable devices. What sets the RX 7800M apart is its striking resemblance to the newly unveiled PlayStation 5 Pro, thanks to a similar spec sheet that enables it to offer comparable performance in a compact laptop form factor.
The newest laptop graphics card is based on the Navi 32 GPU architecture, sporting 12GB of 18Gbps GDDR6 VRAM with a 192-bit memory bus and a total memory bandwidth of 432GB/s. It boasts 48MB of Infinity Cache, 60 Compute Units (CUs), 90 Render Output Units (ROPs), and a thermal design power (TDP) of up to 180 watts. Operating at a frequency of 2.145GHz, it supports popular video rendering formats like H264, H265, and AV1.
The RX 7800M is equipped with Infinity Cache technology, optimizing memory access and enhancing efficiency by minimizing the need for constant memory fetches that can bottleneck performance. This feature enables the GPU to deliver high-end gaming performance while maintaining better power consumption, a crucial advantage for laptops concerned with battery life.
With a similar memory capacity and computational power to the PS5 Pro, the RX 7800M provides a compelling option for gamers seeking a console-like gaming experience in a portable package. Supporting high-fidelity gaming at resolutions of 1440p or higher, it caters to gamers desiring detailed visuals without sacrificing frame rates. While the PS5 Pro is intended for stationary gaming, the RX 7800M opens the door for gaming laptops to offer similar capabilities, providing on-the-go gamers with console-quality performance.
While official performance metrics from AMD are pending, a recent report suggests that the RX 7800M outperforms Nvidia’s RTX 4070 mobile GPU. OneXplayer, a Chinese handheld console and mini-PC manufacturer, unveiled its next-gen eGPU solution leveraging the RX 7800M (OneXGPU 2). A video showcasing this eGPU paired with the OneXPlayer X1 handheld, powered by the AMD Ryzen 7 8840U, revealed impressive performance results on 3DMark Time Spy.
