Given the previous collaboration between the two companies on Arm-based Chromebook processors paired with GeForce GPUs, this rumor is not really far-fetched. RTX 4000-like performance on a smartphone would be nice, but AMD and Samsung promised similar things with the Exynos 2200 SoC, and that turned out quite disappointing.https://www.notebookcheck.net/MediaTek-rumored-to-integrate-Nvidia-AI-GPU-in-upcoming-flagship-smartphone-SoC.697053.0.html
Imo would have made far more sense for Microsoft to have partnered w/ Mediatek to produce their own SOC's for Windows ARM than Qualcomm. Qualcomm doesnt take enough risks, and frankly as far as usable innovations go because of their huge cost overheads working w/ Qualcomm is a pain cause they want license money for everything. Not to mention Qualcomm's refusal to create more diverse products outside of its phone operating capacity. Microsoft ought to just cut their partnership w/ Qualcomm short and just swap to Mediatek. Mediatek will be more than willing to make significantly more powerful chips than Qualcomm will. As it stands currently The latest generation 8CX is about as powerful as a Ryzen 3 from 3 years ago.... If 8CX gen 4 isnt going to be much better then Microsoft should really consider changing partners.
