New Laptop, intel pentium core duo i3 processor thingy question

[mcgee9t2]

ok here goes, (i have no idea about laptops ect at all.)

ive done a little research and what i understand the intel pentium processors are older, and the core i3/i5/i7 ones are newer, however when ive looked the newer ones have smaller speeds (is it speed?) i.e:

Intel® Core™ i3-3217U processor (1.8 GHz clock speed, 1066 Mhz, 3 MB cache memory)
as aposed to
Intel Pentium Dual Core B980 CPU 2.4GHz


now obviously if i was comparing a few laptops with the same type of processor ide know just to look for the highest figues

but with these being different, the core i3 ones all seem to have lower figures.

will the bottom still be faster ect than the topcause its got a bigger number, or will the newer technology in the top one make up for this so to speak.

as you can tell i have no idea about technology so go easy

any help appreciated.

cheers

Yeah the i3 will be quite a lot faster than an older Pentium, it's more efficient architecture

sweet i was right.

as you can tell im like an OAP when it gets to technology, only just found out last month after like a year and a bit of owning my phone i can do print screens on it

whats the difference in them  (dont think i worded that very well but cant think how to explain )
i.e the 1.8GHz on the i3 is = ~2.0 on the pentium? 1.5 on the pentium?
what figures would be appropriate to insert into that

again thanks for any help

i.e the 1.8GHz on the i3 is = ~2.0 on the pentium? 1.5 on the pentium?

in terms you'll understand the imagine the i3 1.8 is a 1.8 with a supercharger and the pentium 2.0 is 2.0 8V NA although the i3 has a smaller displacement, the output is higher due to the supercharger.

in terms of comparative clockspeeds the i3 is probably about 200% faster clock for clock so lets say 3.6Ghz, I'm sure with some google searches you'll be able to find accurate figures if you really want.

so what your saying is even though the i3 is only 1.8GHz, it would be like having a 3.0+Ghz Dual core. or somewere around there.

I think clock speeds stopped mattering a long time ago, to a degree.

I remember when the higher the ghz the better the CPU. Now 2ghz CPUs are out performing 3ghz CPUs. Crackers.

visit a website called Toms Hardware, check out the CPU comparison charts. This will give you performance figures in black and white

Along with Tom's Hardware as Chris has said, I find CPU Benchmark a great site to compare CPU's. As a system builder you can compare the value for money, I.E you can get a CPU which costs more but might do the same as a cheaper one, or a cheaper one that is better than a more expensive one.
