Or:

http://techgage.com/print/intels_sandy_bridge_revealed_core_i5-2500k_i7-2600k_reviewed

I7 975 @ 3.33GHz beats the I5 2500K in almost all applications.

I'd really like to see an Overclock.net user actually coming up with a clock-for-clock comparison or at least a valid link.

Saying it's faster clock-for-clock doesn't actually prove it.

Since we're on an overclocking website most people like...overclock...and SB can OC better but I find it stupid how people recommend I5 2500K instead of 1366 for the same price. You'd most likely need 4.6Ghz or so on that I5 to match a 4.0GHz I7.

I would understand if you had a $200 I5 2500K vs a $300 I7 950 but otherwise Nehalem is a better CPU.

The I7 2600K however is 10-15% faster clock for clock so there's nothing to deny about that.

Well, im not actually going to say that the 2500k is faster clock for clock. It depends on the situation. Those benchmarks are likely to benefit CPUs that have more threads. In single or dual threaded applications (which is nearly all programs) the 2500k is likely to be faster than the first gen i7s.

Is the i7 920 using HT during those tests? The benchmark you linked, SiSoft Sandra utilizes multiple cores. Of course a i7 920 + HT is gonna beat a stock 2500k. It's got more cores threads etc etc etc

And yea, OCing to 4.5ghz on a 2500k is dead simple. Some people can do it on stock voltages depending on the batch.

Easy OC, excellent architecture, lower TDP, less heat, equal or greater performance (you stated a 4.5ghz 2500k would match a 4.0 i7). Why wouldn't you get that for the same price? Seems to me like you're just searching for a reason to hold on to your i7.

Be careful about what you say. It has more threads. not cores. rolleyes.gif

920 has the same amount of cores as 2500k. HT does not mean more cores.

Check the second link also with the I7 975 as well as the other pages. It's not just Sandra, it's Microsoft Excel 2007, video encoding software etc.

More threads then. You know what I meant.

the 965 is same clock speed as the 960 so dont worry about that.

The 960 wins in 25% of benchmarks, those being benchmarks that benefit from hyperthreading. Though the 2500k overclocks better(usually) so it could probably beat the 960 in more after they are both overclocked.

the 2500k is much better in single and dual threaded apps, which will likely be the biggest difference

USUALLY? lol, have not seen one i5 2500k that could not hit atleast 4.3ghz(most hit 4.5-5.0), hardly ever see i6 960's running 4.3+ and that in itself is a feat.

OP, get the i5 2500k. It is newer, faster, overclocks easier on air-cooling, and cheaper.

The only reason to get a socket 1366 computer is for a 6-core 970, 980x, or 990x. However, there is no point if you just game. i5 2500k or i7 2600k is good enough and easier on the wallet.

Again, multi threaded applicatons. Excel, video encoding, Sandra, Folding, etc take advantage of as many threads as it can. thats the only benefit of an i7 over an i5 is that it is better for workstation type applications including video editing, excel and things like that. i5 is PERFECT for gaming and everyday usage and high/mid-range multi threaded computing. Even if it were used in a video editing computer I, personally, wouldnt be disappointed by its speed.
