I've just noticed a comparison speed test between an iPhone 3G S and a second gen iPod Touch at http://blackpixel.com/blog/244/early-iphone-3g-s-opengl-test-results/
The first test, which was both GPU and CPU intensive, showed a 2x improvement in speed.
But the interesting test was a CPU only one:
iPhone 3Gs: 6.42 Mflops (small dataset) 5.86 Mflops (large dataset)
2g Touch: 5.21 Mflops (small dataset) 4.86 Mflops (large dataset)
Only a 20% improvement.
The tests are fairly simple, but made me wonder if the CPU really is a 600MHz Cortex A8, as has been claimed.
