If it is really slow on a well configured core I3 or I5 machine then my apologies for my first reply.
Depends on what it's doing.. for my particular test rig (3GHz quad, 8GB, 1GB nVidia) it mostly falls down on the aforementioned Dash (which is painfully slow as all hell) and general video performance (suspect it's due to Compiz.. I hear it's improved in 13.04). Other desktop environments that I've thrown on this hardware running on the Ubuntu core distro run significantly better overall.. it's just Unity. Same distro, slap on KDE or whatever and it flies.. my initial comment was about the "out of the box" experience.

If you know how to run ubuntu and get your hardware properly setup, then you compare windows 8 to ubuntu via geekbench, ubuntu is the faster OS.
Subjective; I can run other programs on Windows that run a fair bit faster than on Linux. Synthetic benchmarks aren't the beat-all thing to pick the better OS. Some things will be faster, some slower.
