Intel Core i7 For Laptops — First Benchmarks
Barence writes "PC Pro has benchmarked the first Intel Core i7 processors for laptops. The chips mark the debut of Intel's Turbo Boost technology, which ramps up the speed of the working cores if two or more cores are sitting unused. For the quad-core i7-820QM, this can take the stock speed of 1.73GHz up to a maximum of 3.06GHz. The 2D benchmarks show comparable performance to Core 2 Extreme chips running at 2.53GHz. Power consumption and processor temperature is dramatically lower, which should lead to significant improvements in laptop battery life."
"Power consumption and processor temperature is dramatically lower, which should lead to significant improvements in laptop battery life."
compared to? Because from the graphs the core2duo had much better battery life, and core2duo battery life sucks imho. Wish they'd focus more on improving the battery life of two cores because 4 cores in a laptop is overkill 99% of the time, I'd rather have a extra hour of battery life and suffice with two cores.

Intel always had the lead in manufacturing capability, and it seems that this is one of the nice results.
This time it's little to do with their manufacturing capability in terms of process size, it's R&D specifically to achieve this. They basicly created a new "shut-off" form of transistor that effectively blocks off everything behind it. You can read more about it here.

Seriously, couldn't the marketing droids come up with a better name?
Sadly, this technology was called "Intel Dynamic Acceleration" (IDA) in Core-2 CPU's, but nobody noticed it. So, Intel tried with "Dual Dynamic Acceleration" (DDA), but again, nobody noticed. At last, renamed it to "Turbo Boost" and now everybody thinks it's something new.
So, after three attempts, it seems that the current name is the best.
