Smaller AMD Navi 31 GPU from RX 7900 GRE reportedly coming to Radeon RX 7000M mobile series

AMD preparing Radeon RX 7900M with Navi 31?

A trusted hardware reviewer and leaker, Golden Pig Upgrade, claims that AMD now has a plan to bring its new Navi 31 GPU to the laptop space. 

The rumor suggests that there might be a plan to utilize the same GPU found in the Radeon RX 7900 Golden Rabbit Edition (GRE) for the mobile series. This special edition of the desktop GPU line employs a smaller package known as Navi 31 XL. Despite sharing the same compute die as the flagship Radeon RX 7900 series’ Navi 31 XT/XTX models, the GRE version has two disabled Infinity Cache units and a Navi 32-sized package.

The notion that the smaller Navi 31 GPU could find its way into a laptop form factor wasn’t originally presented by the Golden Pig Upgrade. It was first mentioned by Moore’s Law is Dead, who revealed the plans for this new graphics processor about a month ago.  However, at the time it wasn’t known that AMD was preparing an RX 7900 GRE desktop GPU.

This desktop model boasts a Total Board Power (TBP) of 260W, which is excessive for a mobile device, as opposed to the 175W TGP of the NVIDIA RTX 40 series for mobile (with Dynamic Boost). Nevertheless, indications suggest that the mobile variant could potentially feature more cores than the Navi 31 XL’s 80 Compute Units (5120 Stream Processors). AMD might opt for the most power-efficient variations and underclock the GPU to achieve the desired level of performance, which should still be significant.

Report indicates that this GPU isn’t quite ready for launch. Specifically, a laptop intended to feature this GPU has experienced delays. Notably, AMD recently introduced the Ryzen 9 7945HX3D processor with 3D V-Cache, exclusively available in an ASUS ROG laptop. One might speculate whether the initial intention was to use this platform for the Navi 31 mobile launch, but this laptop has instead opted for GeForce RTX 40 graphics.

The AMD Radeon RX 7000M series appears to be gradually taking its final form, following its understated launch featuring Navi 33 based components a few months ago. Despite the RX 7000M series currently not being a prominent choice among laptop manufacturers, the introduction of a potent RDNA3 GPU could potentially alter that landscape.
