Courtesy of the lovely Lisa Gade at Mobile Tech Review (she's becoming my go-to for hardware vid reviews) https://www.youtube.com/watch?v=Yve9TB-fXV8 This Zenbook UX305 has the same line of Core M processors that's in the new rMB, except at 800MHz!, turbo to 2.0GHz (remember we get 1.1GHz, 1.2GHz and 1.3GHz, Turbo-ing to 2.4, 2.6 and 2.9GHz respectively). Unlike the Yoga Pro 3, this one's also fanless. Some people here are correctly pointing out that the rMB wont be ideal for sustained performance so many common benchmarks aren't that useful, the processor excels more in bursts, similar to actual usage among most folk. Ok real world performance on this 800MHz machine? Absolutely perfect for my use, no lag in the 1080p youtube video or surfing websites. She demos internet explorer tabs around 11:30, and even tries Skyrim (low settings) at around 15:20, even that runs better than I expected. Battery for the Zenbook is stated as 10 hours, she gets 9.5! Only caution so far is that the Zenbook is driving 1,920 x 1,080 pixels, the rMB will be pushing more at 2304 x 1440. That said, Asus are shipping this Zenbook with an optional 3,200 x 1,800 from April, so if they're happy with the Core M pushing that, I can't imagine the rMB will be overstretched. Color me excited!
