Lenovo IdeaCentre A700 all-in-one

Performance
While the design of the IdeaCentre A700 may be on the leading edge of desktops, performance isn’t. It is, however, on the leading edge of mainstream notebooks, thanks to the high-end (for a notebook) components inside of the machine.

The quad-core Intel Core i7-720QM is only clocked at 1.60GHz, but don’t let that fool you – it’s still substantively more powerful than a similarly clocked 1.6GHz Intel Atom, for example.

Since it does have multiple physical cores (and even more “logical”, or microcode-enabled, cores), the A700 will excel at tasks which benefit from multiple CPUs. These include multi-tasking of disparate programs, since the OS can intelligently manage workloads, tasks which are sufficiently parallelizable (this means tasks that can be broken into small chunks and processed independently on different CPU cores), sufficiently-advanced games and so on.

Where high-end mobile CPUs like the i7-720QM are beaten out by higher-clocked, fewer-cored alternatives are tasks that are unable to be run on multiple cores at the same time. Some games, for example, aren’t as efficient at using more than two cores, and will run better on a dual-core but high-speed CPU than a quad-core but low-speed CPU.
