iPad 2 benchmarked against iPad 1, others...

I think it's 4x faster than the iPad running the current revision of the OS, which clocks in at 8321ms.

Yes, that makes sense. So really a fair comparison (as mentioned earlier) between iPad1 and iPad2 is with both at the next IOS revision. In that case, the speed difference doesn't seem extremely significant (at least from these Sunspider test results), and compared to Galaxy Tab.

Seems to me the iPad2 is moderately faster than iPad1 from these numbers - 35% more, not 4 times. The Galaxy at 7066ms looks like the significantly slow device here.

35% is pretty much in the ballpark I expected a Cortex-A9 at the same clockspeed compared to the older A8 in this kind of CPU test.

The real fun part is what if you have to run two of these tests? The iPad 1 will take about 6500ms whereas the iPad 2 can theoretically finish it about three times faster

On SunSpider 0.9, rather than the 0.9.1 that cnet ran - 0.9.1 appears to be showing slightly faster scores all round though.

For comparison, the MBP in my sig got a score of 335 and my 3GS running 4.2.1 got a score of 13,519

And post-4.3 install, my 3GS is now scoring at 5,530 - if all things were equal, that's a heck of an improvement!

the ipad1 scores look really impressive post-4.3; is it really that snappy? I'm wondering if it's even worth bothering to get the new ipad if you already get a 2-fold improvement just from the software.
