With the DSi now officially out in the wild, Japanese site Impress Watch decided to pick one up and dissect its contents, taking an in-depth look at the electronic innards of Nintendo’s third-generation handheld. While the most obvious and noticeable additions are the refined stereo speakers and slightly larger LCD screens, there is one significant change elsewhere that may be more difficult to spot. That difference being the DSi CPU, which sports a revision identifier stamped on it that reads “TWL,” with a chip finalization date of 2007. By contrast, the CPU housed inside of the DS and DS Lite was produced in 2004 and both models had near-identical revision identifiers, “NTR” and “NTR B,” respectively.

Seeing as Nintendo decided to add extra RAM in the DSi, it’s plausible that the CPU clock speed was bumped up as well, presumably to allow for smoother operation in the handheld’s built-in internet browser. It’s only a theory, though. We won’t know for sure until the more experienced hardware gurus take a look at the unit.
