What characteristics to choose a processor?

Question

Iron

A little santa barbara

spoiler

Recently I was invited by an expert to choose a cheap educational laptop for my sister ... I settled on Lazy with Stump , 4 GB of RAM, hdd, without discrete and axis ....

The thing is that Penek , judging by the characteristics, is far from bad .... (4 real cores (and not bonfired ones (as in core i3-i7)) self-acceleration up to 2.5 GHz sounds cool .... There weren’t any in the store the opportunity to look at the Internet, and the computer was without an axis (FreeDos) ... We rolled a figure eight on it and put firewood ... It seems to be normal ... it slows down a little, but oh well .... .... until you know it, you didn’t come with a laptop where the i5-32 stood?? and it was VERY different in speed, although the frequency was slightly lower and there were only two real cores ...
QUESTION: Is the only indicator of processor performance left tdp (Heat dissipation (you can’t hide from physics)) or HOW EVERYTHING- DO EVALUATE THE PERFORMANCE OF PROCESSORS, if the comparison in terms of frequencies and the number of cores cannot be trusted (See above for what)

Answer 1

Cash, Carl! cache
and also in it is rather weak video and HDD

Answer 2

and what do you want, this calculator does not have a level 3 cache, not at all + a fucking RAM subsystem, consider level 1-2 caches only for beauty, it seems to be okay)
sc5.stdns.ru/up/blog/cache/content /10308_25.141171... now the RAM is faster on I7 than this L2, and its 32 gigs, by the way, and not 0.002 like here
But look at ThrottleStop, does it work on the x31 multiplier, can you still increase the frequency
Yes, and in budget laptops only 1 chip of RAM, works at half speed, maybe add a second one, it will be faster.
PS I don't know what time I write this, probably the millionth
You can buy 2 of the fastest DDR3-1866++ memory modules, downclock them to DDR3-1333 and set the minimum timings, there will be a small increase (no matter how you lie% 30) or find flaws and shove them under warranty, taking another more powerful one

Answer 3

"HOW TO EVALUATE THE PERFORMANCE OF PROCESSORS", compare here: www.cpubenchmark.net , from experience, you can rely on performance data.

Answer 4

There is also such a thing as "processor architecture".
Here is a whole community for you, mad at the choice and evaluation of hardware and maximum performance: List of forums » Thematic forums » Processors

Answer 5

but no way. there is a cache. there is a wagon of architectural features. TDP will not give you anything either: the current Core M with a TDP as much as 4 watts works no worse than the low-voltage core i3 with three times the TDP. i7 new ones with power consumption reduced to 15 watts are many times more efficient than the old core i3 with a TDP of 65 watts.
you need to look at real tasks and purchase a processor based on them. no other way.
