In typical Apple fashion, they announced the new third generation iPod touch 32GB and 64GB as being 50% faster than the previous generation (the 8GB is the same old bag as last year), with nary a word on what chipsets made it so.
Well, some digging has been done, and some benches have been marked, and the early word is... zoom zoom.
Macworld's tests show some impressive gains. Boot went down from 31 to 19 seconds. Launching apps went from 12, 20, and 10 seconds to 7, 15, and 5 for Peggle, HR Battle, and Rolando 2 respectively. Web page rendering for the NYT site was down from 34 to 15 seconds, and the Sunspider JS test went from 34.2 to 15.6 seconds.
So, yeah, about 50%.
TAUW, meanwhile, went to the heart of the matter, and discovered that the new iPod touch shares similar, if slightly incremented internals over this year's iPhone 3GS. More plainly, same Samsung ARM Cortex A8 processor (S5L8922X, however, as opposed to the iPhone 3GS S5L8920X). No word yet on what may be different, if anything about the PowerVR SGX graphic core, but as we heard already, the 802.11n potential is in the WiFi chip.
The second generation iPod touch was faster than the iPhone 3G, so it's not hard to imagine lack of cell-radio concerns and slightly new components could push the third generation iPod touch across the finish line before the iPhone 3GS as well.
