Leak suggests AMD's best laptop GPU delivers RTX 4070 desktop performance for less power
After what seems like an interminable wait, AMD's Navi 32 GPU is finally starting to break cover. This is the second-tier RDNA 3 graphics processor, and only the second ever to use AMD's new GPU chiplet packaging techniques. The red team seems to be focused on the mobile market at the moment, and the fact that it's the laptop versions of the RX 7800-series silicon that has been leaked is telling.
That does, however, mean we're still likely to be waiting a while for the desktop card to arrive, either in RX 7700 or RX 7800 trim.
Twitter leaker, All_The_Watts has listed the expected specifications for five different Navi 32-based mobile graphics cards. While there is no way to 100% verify the truth of these rumoured specs, they look pretty likely and consistent with the previous generation of AMD mobile GPUs.
They have also posted a shot of a 3DMark Time Spy benchmark supposedly from an RX 7800M XT run, and it's way beyond what the best of the last-gen laptop Radeon chips could muster. I mean, hot damn it's offering RTX 4070 desktop performance.
The average from an RX 6850M XT is around 11,000 points, and the RTX 4070 is around the same 17,800 level. This does speak well to the performance of the Navi 32 silicon, which has been a concern given how late to the party AMD has been with its second-tier RDNA 3 GPU.
The RX 7800M XT is the top mobile chip of the next-gen Radeons, and the fact it can apparently deliver that level of performance with a total board power of some 189W is impressive.

That should translate to good desktop performance if, as expected, the RX 7800 XT comes with the same essential GPU makeup, but with a higher clock speed and moar
