i5 2500k Vs i7 940

post #1 of 31
Thread Starter 
Heres the deal. My friend and I are having an argument over which CPU is faster.

i5 2500k Vs i7 940

I'm not just talking about gaming but other bench mark tests, such as multitasking and can proccess most info in shortest amount of time.

I want to know which CPU is faster overall. In games, processing power, multitasking.... the whole lot.

One simple link

http://www.anandtech.com/bench/Product/46?vs=288

Sorted

P.S that i5 is at stock, so tbh, it'll beat the i7 on everything when it's been overclocked to 4.5Ghz or above.

Well, at this rate, a i5-2500k. - Yep! It's a 2500K.

That, and It OC's like three bazillion Ghz over stock (slight bit of over-exaggeration).

That, and a i5 is a 32nm CPU and a 940 is a 45nm CPU.

Overall the 2500K is quite a bit faster, but there are some specific apps that take advantage of the hyper threading that only the i7 supports. Here are some details:

Well the 2500K has four threads while the 940 has 8 threads( including HT )

The 2500K has no problem reaching 4.7Ghz while the I7 940 has problems reaching 4Ghz.

At these clocks the 2500K beats the 940 at everything including Cinebench 11.5 which is a Encoding Benchmark.

The 2500K is a monster of a cpu.

Lolz,

Great minds bro, great minds!

What about throwing my cpu in there? That should make it a touch competition tongue.gif

*sigh* I remember when people love my cpu for its overclocking power...

Dude, don't worry about it. Tbh, your rig is still perfectly suitable for high end gaming. If I had your rig when I baught mine i wouldn't have bothered upgrading (I didn't have a machine, hence the i7).

Remember, games use GPU's more often than a CPU.

Yeah that is true, and to be honest, my next upgrade will probably be a case.

Although I am hoping to do a near complete rebuild once ivy bridge comes out, but I don't really know how that compares to Sandy Bridge-E.. I haven't been listening because it upsets my 65nm tongue.gif
post #10 of 31
Ivybridge should be about the same step from sandy as sandy was from nehalem, that's what I would have thought anyway.

Tbh, at that point, your rig has obviously had a full and worthwhile life, you could consider selling your rig either as parts or as a whole to fund your new rig.
