[citation][nom]haswell5271[/nom]If the OS was light enough? I would bet it could. Windows 7 is very heavy compared to Android, and because it's flash architecture is might be faster memory than my 7200 RPM HDD. Also my i5-3570K isn't overclocked. It's actually underclocked to 2.9 GHz to lowers temps (I don't need and more speed). You have to give Samsung some faith mate.[/citation]
It doesn't matter how good Samsung did. The CPU is still just a quad core Cortex A15+quad core Cortex A7 at best. What I think of Samsung doesn't change the fact that a very, very low end CPU will not beat one of the highest end consumer CPUs available.
You are greatly overestimating the influence of Windows 7.
Even with that considerable underclock, a single core of your i5 will beat the Exynos 5 in eight-threaded software by huge margins simply because it's that much faster than ARM. There is a huge difference in power consumption, performance, and price for a reason. I've got nothing against Samsung, I even own several Samsung products, but they can't make an architecture perform better than it is capable of performing.
Also, you seem to not understand how fast the on-board flash of modern devices really is. Sure, it's not junk, but it's no speed demon either. A cheap SSD can be exponentially faster and be much faster even in more real world scenarios the benchmarks and unusually high usage situations.
I repeat: There is no chance, whatsoever, of your i5 being beaten by Samsung's Exynos5 unless Samsung managed to get more than an order of magnitude improvements to meet desktop performance without desktop nor even low end laptop power consumption. Since Samsung did no such thing, the i5 will win without any performance competition, granted it is an apple s to oranges comparison.
