understanding the new cpu's

distantthunder · May 28, 2014

can someone explain to me why the new laptops have something like this as a cpu Intel® Core™ i3-3217U processor with a letter U at the end. and when i go to look at intel for the cpu speed as some store dont say this. its a 1.8GHz. its like speeds of laptops are going slower than faster.

looking for advice to understand this and what to look for when going for a new laptop. thanks in advance

The U models are ultra-low-powered CPUs for small form mobile PCs used to reduce power usage and extend battery life.

U mean for Ultrabook. it mean for light latptop.

I have a new laptop (technically not an ultrabook) with a Core i5-4200U; it's still quite speedy enough despite the 1.6GHz base clock. Remember that those low base clocks are accompanied by much more aggressive turbo boost speeds (in my case, 2.6 GHz)

MX_ Mobile extreme edition___ Highly Overclockable, Upgradable, highest performance, uses the most power.

MQ_ Quad-core mobile ___ Lower power consumption and performance compared to MX CPU, Upgradable

HQ_ High performance graphics___ Needs more power over a standered M CPU, Not upgradable or replaceable, includes highest integrated graphics.

M_Mobile___ Mobile processor line

U_Ultra-low power___ Significantly lower power and performance compared to M CPU, Not possible to upgrade or replace

Y_ Extremely low power___ Usually lowest price and performance and power use, not upgradable.
