We start the performance section of this review with a look at some of the key system performance aspects of the Inspiron 14z and in doing so will be comparing it to a system based on the last generation of mobile Intel technology, MSI’s GX660R which uses the i5-460M as well as Dell’s own core i5-2410M based XPS 15z.

One of the key results in this test is that there is a noticeable gap between the i5-2430M and i5-2410M which is a nice benefit of the 14z. When we look at the memory bandwidth though it is clear that the 14z would benefit from one of the dual channel configurations which would take it closer to the 15z, though this system still manages to match the older i5 architecture which itself is dual channel. Moving on to hard drive performance we see that the 5400rpm HD used by Dell tops out at around 85MB/s, a 7200RPM model would take us up to 100MB/s. USB 3.0 performance is exactly where we would expect it to be, 4-5x faster than USB 2.0.
