Phone and computer CPU comparison

[Pawnless Endgame]

Sorry, please move this to the phones section. Thanks Dons.

Phones are hitting nearly 2GHz now, with multiple cores, at least 1GB of RAM and some are 1080p as well. This spec is equivalent to probably a late 2007 PC with Core2Duo processor and HD-ready, so phones are catching up.

Is there a benchmark to compare PCs and phones clock-for-clock? Also, how does the Tegra series of graphics chips compare to the various GT and GTX cards?

I'm still on a Sammy SII, but am interested to learn of any app that really taxes it. For example, I have a racing game called SpeedX 3D which is a nice demo for graphics and the SII handles it well. Just looking for similar, gaming or otherwise.

Cheers for the answers guys. I know it's a more complex question nowadays than, say, the 1990s when it was just about chasing the megahertz. Then the Millennium came and CPUs gained extra cache, hyperthreading, more cores, more levels of cache, even more cache and so on, which makes it harder to quantify 'CPU speed'. Is there a single ultimate stat that can be calculated from all of the above criteria so that it is easier to compare i5/i7 processors vs Atom processors vs phone processors, or is it not as easy as that? I might have the wording wrong, but I was thinking along the lines of 'floating point value'?
