[VTZ] Intel Core i5 2300 2400 2500K Sandy Bridge Review - Page 2

post #11 of 18
Am3 users are waiting for the mythical BD.
I prefer 4 fast cores vs 8 slower cores.

So basically a Stock clock (2.6GHz) 920 is on par with a stock clocked 2500k (Which, btw, is clocked much higher, at 3.3GHz, roughly 30% higher).


Are you sure that we are looking at same review ? i5 2500 was faster in almost every single benchmark. Even i5 2400/2300 was faster in many of these bechmarks

I going to show you some benchmarks here

Some games are GPU limited, so even you overclock the CPU to 4GHz you won't see much performance gain.

But for some odd reason i5 2300 (2.8GHz) performed better than i5 2500(3.3GHz) in metro 2033 even though i5 2300 is clocked lower.

EDIT: Also i5 2300 performed better than i5 2400 in 3dmark. For some reason I don't trust this review. There are many other reviews for sandy bridge. So, people should check other reviews before taking this review seriously.

The other reviews shows i5 2500 being faster than even i7 950 in most cases

You sure you even read what he posted. He said they are compairing a stock clocked 920@2.66ghz with a turbo to 2.93ghz to a 2500k@3.3ghz with a turbo to 3.7ghz. There is quite a disparity in clocks. Even the 2300/2400 are stock clocked 300/400mhz higher than the 920. What they should have used was similar clocks to show the architectural differences.

Yeah, the pics posted are of 4.3Ghz i5 2500k vs. stock i7 920- we'd need benches of both procs at stock clocks or the same clocks to determine the difference.

2600k, but it will produce much more heat.

Tweakers.net has put up some benchmarks
here is one example.

2300 and 2400 locked, 2500k and 2600k turbo overclocking only,which means they will always idle at stock clocks.
