But after three years you decide you want a new car. If you trade in the Altima, you will likely get about 46% of the sticker price, or $10,621 (the resale value after three years, according to the Kelley Blue Book). Then you'll have to pay off the loan. Figure your total out-of-pocket cost will be $9,525.
The Y-series CPUs have a six watt SDP, down from seven watts in Ivy Bridge and they also have a 9.5 watt cTDP between the max TDP value and the SDP value. U-series CPUs also have a cTDP of 11.5 watts, but don't have a validated SDP value.
Short answer: i3/i5/i7 CPUs are better at running multi-threaded applications. For example the G3258 and the i3 are both dual core processors but the i3 can perform hyperthreading meaning each core can run two threads (giving the equivalent of 4 virtual cores). There are currently two different lines of Celeron and Pentium CPUs.
