Intel Ultrabook’s low powered processors are slow

cpulaptopperformanceultrabook

I am planning to buy a new laptop these days and for that I am searching for online user reviews etc. these days.

Laptops that I have shortlisted includes HP Envy 6 which is an ultra-book and have an Intel® Core™ i5-3317U Processor However while searching reviews I found it written somewhere stating this these low powered processor are actually a big setback for performance having an ultra-book (low powered) i5 processor will give you performance like a normal i3 or even worst.

Being worried about that i searched for little knowledge for ultra book I found contradicting statements as on Intel's site it states:

Why settle for the machine you have, when Ultrabook™ 2 in 1 offers so
much more? Convert it, touch it, wake it in a flash. Multitask with
blazing fast performance, access files in a snap, use it all day long…and enjoy peace of mind with built-in security.

And on Wikipedia it also says:

Ultrabook is a specification and brand developed by Intel for a class
of high-end subnotebooks which are designed to feature reduced bulk
without compromising performance and battery life. They use low-power Intel Core processors…

Now beside what I read I myself is also confused whether something that is low-powered would actually produce similar performance results as its normal powered counterpart? If yes than why we have normal powered processors out there.

Question in one sentence:

Does these Ultra book low-powered processors gives Low Performance results as compared to their counter parts i.e. an Ultrabook i5 is not equal to a Normal i5 ?

Best Answer

The U/ULV versions where always slower compared to the normal i Core CPUs but consume less energy and generate less heat.

If you want high Performance buy a Desktop PC with i5. If you want mobility with power use a normal laptop with a normal i5. If you want maximal battery life and don't need power all the time buy such an Haswell U i5 to get a good balance between battery life and CPU power.
