AMD have quietly launched a new mobility GPU for its ever-growing RDNA 3 family today, aimed at high-end gaming laptops and equipped with the same compute units as the PS5 & 7800 XT. The GPU was ‘announced’ on the official AMD website via a product page which showcased launch dates, specifications, and more. While no official gaming laptops have hit shelves using the newly announced RX 7800M, experts predict that stock availability for these laptops will be much higher than the flagship RX 7900M and mainstream 7600/7700 variants. Of course, only time will tell on that front, but early signs are looking quite positive for the upcoming mobile GPU. In fact, early 3D Mark benchmarks showcase a mere 15% difference between the 7800M and 7900M, which is not horrendous when all things are considered. AMD RX 7800M specs go live AMD RX 7800M specs list. Source: AMD Looking at the specifications, the 7800M is based on the 5nm NAVI 32 GPU silicon, equipped with 30WGPs and 60 Compute Units (similar to that of both PS5 Pro & RX 7800 XT). It features 3,840 stream processors on a chip that stacks 28.1 billion transistors, plus 96 ROPs and a maximum texture fill rate of 560.4 GT/s. To put that in perspective, that’s the same core count as the AMD RX 7800 XT desktop GPU and the recently announced PS5 Pro console from Sony. As for clock speeds on the newly announced 7800M, users can expect 2,145MHz in game frequency mode – which is far less than the 2,430MHz boasted by the 7800 XT. This is mainly thanks to the compromises made when working out the chips TDP. How does the 7800M compare to the desktop 7800 XT? Of course, comparing the mobile-tailored 7800M to the desktop 7800XT is like night and day – however, it’s worth a look to get some perspective on how it may perform in flagship games. The 7800M will feature 12GB of VRAM whereas the 7800XT offers 16GB, with the latter also featuring faster memory bandwidth, meaning it should be easily outperformed by its desktop counterpart. All being said, when you look at mobile vs mobile options, the 7800M looks fairly well placed, boasting a 28% increase over the NVIDIA GeForce RTX 4070, respectively.
