Just to throw something onto the rumour mill Nvidia has announced the GTX 1050 Pascal GPUs, which release 25.10. These GPUs have TDP of around 75W and with some binning and underclocking, would perfectly fit into the 15" MBP. Coincidence? Or is the next MBP coming with Nvidia's Pascal? There is be a number of reasons why this could happen: - The Pascal GPU is the most efficient design on the market right now, offering trully stellar performance. The performance boost over the M370X would be in the ballpark of 2x or more - Apple usually switches between Nvidia and AMD every few years, and they have been using AMD chips in the last iteration - The timing of it all. Isn't it convenient that Nvidia announces a suitable chip just two days before Apple's reveal?
