Since the Dell Inspiron 14z is running on Windows 8 while my desktop is on Ubuntu 12.10, I'll be attempting to run cross-platform benchmarks to provide a common comparison scale. Right now it's just Geekbench but I'll add more results if there's interest.
|Geekbench overall score|
Let's break it down by category.
|Geekbench results by category|
Being a mobile solution, you could say Intel's hardware is at a disadvantage here. In that light, AMD's old guard could have perhaps done better. In doing this comparison, I've learnt that cross-platform benchmarks are surprisingly hard to come by. GPUtest is doesn't run on Linux despite claims to the contrary, for instance.
Further breakdown of the scores is possible. Check out the full AMD results and Inspiron 14z results on Geekbench. Hardware specs can also be viewed from the results.
