A Dell Inspiron 14z vs desktop performance comparison

This is a performance comparison between the Dell Inspiron 14z and my primary desktop system. It's not a apples to apples comparison so if that's what you're looking for you'll be disappointed. This comparison is meant to give a relative performance difference between these two systems.

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
My desktop is running on generations old AMD Athlon II X4 2.6 GHz while the Dell Inspiron 14z comes with an Ivy Bridge Core i3 1.8GHz. Despite that, the desktop system still scores higher than the notebook. With so many benchmarks online showing just how much more superior Intel's processors are compared to AMD's this is perhaps a very surprising result.

Let's break it down by category.

Geekbench results by category
Looking at the category breakdown we see a clearer picture. AMD's processor outpaces Intel's in floating point processing. Most likely it's the multi-core benchmarks giving it a very big advantage. When it comes to memory performance, Intel wins hands down. Integer performance is on par.

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.
