You will be sorely disappointed if you expect those CPUs to have a 10x difference. First, you have a 2.75x clockspeed difference and then a double core count so 5.5 times is what you could expect if they were the same architecture but the 6Y75 is Skylake (don't be mislead by the "Core M" moniker, these the same architecture as their larger wattage brethen just with a lower TDP, they used to mark them with an Y postfix like i3-4220Y and the Y is still in the moniker) and the 5775C is Broadwell but it has eDRAM so the difference is negligible here http://www.anandtech.com/show/9483/intel-skylake-review-6700k-6600k-ddr4-ddr3-ipc-6th-generation/9 http://www.anandtech.com/show/9483/intel-skylake-review-6700.... So in real world, you can expect to see a 3-5x speedup.

Ah, that explains that. Bearing in mind I'm thinking of upgrading from an AMD 350e Fusion CPU, so I know I'll be blown away by the performance of a new machine. It's just picking the right form factor. I can't wait to see how quickly mutt and vim load. [Removes tongue from cheek]. In all seriousness I do run a VM, a situation I'm trying to address by writing the main software tool I use in Windows as a Vim plugin. The VM works for now, but is obviously a strain on a minimally resourced system. And if I'm completely honest I'd love to be able to run my business and do all my work from a Raspberry Pi and/or netbook (think Chromebook pricing but entirely Linux friendly). I'm only editing text, why complicate things!?

  Did you mean the AMD E-350? That's competition for the Atom CPUs not these ones.

    Yes, absolutely. I'm not comparing it to the Core-M/iX range though, just making a point that in my situation either of those will be a vast improvement. Despite the fact that the E-350 does what it needs to just fine right now, it could be a touch quicker.

Yes, 3-5x (peak performance) sounds quite reasonable. But 10x is not out of the question under high load for extended amounts of time (like compiling big software) when you take the form factor thermals into account. A laptop like that will start throttling quite aggressively quite quickly. The Zenbook I have isn't a powerful computer by any measure. It's a fine laptop for light use but the CPU and thermal characteristics aren't suitable for intensive computation. I'd expect any fanless desktop computer to wipe the floor with it when it comes to perf.

  This is why I rent a server at Hetzner. Considering you can get an i7 3770 for 33.61 EUR a month, it's pretty economical. It also serves as a backup (2x3TB) and occassional webhost.
