Of course, this is a rumor. A leak of a rumor. Or a rumor of a leak, however you want to think about it. But, according to those rumors, leaks, and whatever else, it looks like Intel is planning not only a 1.33GHz update to their Core i7 chips in the Summer, but also a bit more power later in the year. We're always a fan of more power, especially if these leaks are anywhere near true.
The low-voltage chips are featured in set-ups like the new MacBook Pro line-up, but they're not quite at that 1.33GHz (which can be overclocked to 2.4GHz, if you're into that kind of thing) level. But that's not good enough for Intel, because they've apparently got an ultra low-voltage chip, the 680UM, ready to launch in the Fall. The chip would feature the same 18W thermal peak, but apparently it can be overclocked to 2.53GHz in Turbo Boost mode.
Of course, this is just a rumor (if we haven't said that enough), but there's definitely something inside us that says this might turn out to be true. After all, computers keep getting better, so why would Intel take a break, right? We'll have to wait and see what happens with this, but we should see some kind of announcement, whether leaked or official, in the next few months.
