Microsoft has offered up more specific details on which processors are in each version of the Surface Pro 4 and its first laptop, the Surface Book. Both are using ultra-low power 15 watt chips. The part we're really curious about, however, the Surface Book's Nvidia GPU, is still a bit of a mystery.
The high-end version of the Surface Pro 4 tablet has a dual-core 2.2 GHz Intel Core i7-6650U Skylake chip, along with an Intel Iris 540 GPU. The next step down has a 2.4 GHz i5-6300U with Intel HD Graphics 520. The cheapest option will have a 900 MHz Core m3-6Y30 with Intel HD Graphics 515.
As you'd probably expect from a Surface tablet, those low-power GPUs will be able to play games on low settings, or handle older, less demanding small games fairly well.
