I've seen a few posts on here from folks trying to decide between the MacBook and various Lenovo devices. I've been tossing around the idea of picking up a MacBook and wanted to see how it compared against hardware that I already own/use. I have a Lenovo X230 that I dig out from time to time when I don't feel like booting up VMs on my 15" rMBP. The X230 is generally well-regarded - a bit old, but certainly a solid business ultrabook (I use the term generously - it's rather thick). I actually run a number of VMware VMs on my X230 and have never really had an issue with poor performance. In fact, if my rMBP died tomorrow, I could probably do all of my day-to-day sysadmin and development work on the X230 (aside from XCode-related stuff, of course). So, I decided to run Geekbench on it and compare against the 1.2 GHz 12-inch MacBook. And, interestingly enough, they're very close, with the MacBook winning overall. My X230 has a 2.6 GHz i5 3320 CPU (not a ULV processor) Lenovo X230: Single-core: 2108 Multi-core: 4670 http://browser.primatelabs.com/geekbench3/2952550 MacBook 1.2: Single-core: 2385 Multi-core: 4797 http://browser.primatelabs.com/geekbench3/2952267 Not sure if this is interesting to anyone else or not, but it certainly helped me decide. If I can get away with the X230 for my workloads (Linux VMs, Python and Ruby development, some PostgreSQL stuff and general system admin), then the 12-inch MacBook will do the trick too.
