CPU with the fastest core

The image shows the reason for my question looking at the 100% load on core #3

core100.jpg


I would like to buy a new CPU but I need one with the fastest running single core.
What CPU has the fastest core?
I think it's the Intel Core i7 990X 3.46GHz or is it just faster as it has 6 cores.
How much faster would the fastest core be compared to the CPU I am running at the moment @ 3.80MHz.

Sorry if the question is a bit dumb as reading it back it looks dumb to me :(

But I get confused with all this Core#, Frequency, Multiplier, L2 Cache, L3 Cache, QPI, TDP talk.

Overclocking the CPU is not a option so would need to be stock speed as I have big cooling problems that can't be helped.

Thanks

Fastest on one core? Sandybridge. The i5 2500k or i7 2600k would be fastest in core for core speaking. The only real advantage of the i7 over the i5 is hyperthreading and seeing as you want one fast core, I think you'd want an i5 2500k.

Also if you were really desperate with cooling and you only wanted to run one (or two cores) you can boot with as many cores running as you want using System Configuration on Windows 7 (providing that's your operating system). And then you could OC one core to 5Ghz with no cooling problem I hope. (Not 100% sure on the last part, but i've definitely experimented starting my PC with only one core active).

Hope that helped...
 
i7 2600K has the fastest cores, but TBH a 2500K would be a better buy. Out of curiosity why can't you use more than one core?
 
A Core i3 has the same amount of L3 cache per core as a Core i5.

The Core i3 2130 dual core runs at 3.4GHZ and has a 65W TDP meaning it will be easier to cool:

The 65W Core i5 2500S runs at 2.7GHZ nominally and has a maximum Turbo frequency of 3.7GHZ:

There are some dual core socket 1366 Xeons which run at up to 4.66GHZ:

Edit!!!

I have now corrected the first link!

WOW! Surprising figures man.
 
Sorry for the long delay in replying to the thread I started.

Thanks for your time & help.

The program that is only using one core is MS Flight Sim X so nothing exciting.

I already have one of the best cases for air flow cooling & a good CPU Fan the problem is my PC is under the stairs so it's trapped in a small space that gets warm/hot quickly.

I am thinking of making a hole in the outside facing wall & adding a fan to take the heat away & draw cooling air in from the rest of the house but I have not got to that stage yet.

Looking at what has been posted I would be better sticking with what I have for now & maybe work on the cooling as I play other games that use all the cores I don't want to make them slower.

Will wait a year & see what's out then.

:D

Loooool, dont worry mate, many a dumb question I have seen but that is not one of them! but yeahhh fastest single core your probably looking on one of the sandybridge's
