The Surface Pro 4 features the same dual-core Intel Core M processor as the Surface Pro 3 and 2 models, but it's the Surface Pro 4's GPU that makes all the difference. In the Pro 3, the Core i5 processor melted the GPU, and without a GPU, you're limited by the Core M's underclocked abilities. The Surface Pro 4 is faster than any Core i3 or i5 configuration, and even than the Surface Pro 3 models.
If you're a hardcore fan of Surface Pro, you may already have a Surface Pro 3 or 4 in your power center and would just prefer a few more megapixels over the Surface's 1.9MP sensor. If so, you can also nab the top-of-the-line Surface Pro 4 for $899, which comes with a stylus and is the only 64GB option in the Surface Pro family.
But in its sleep state, the Surface Pro 4 consumes less power than the Surface Pro 3 or Surface Pro 2. It also has more than enough power to escape, topping out at 9 hours. Finally, it also has a larger battery (65.8mm versus 53.2mm) and the Surface Power Cover, which has a 20 percent battery conversion rate. 7211a4ac4a
