Please take note that is not a totally fair comparison since the i5-750 system has twice as much memory and it seems to be using a RAID-0 for the drive system versus a single drive for the AMD, which at least is an older Raptor. But even with those handicaps the Phenom II 940 has no problem competing with the i5-750. The i5-750 does better in the tests that the Intel chips are known to perform well at. (Super-Pi, FFmpeg, Byte, 7-zip etc.) But for the most part the Phenom II 940 @ 3.0Ghz performs better overall. Also notice that the AMD system had the "Cool'n'quiet' enabled which actually is detrimental to benchmark results; if the tester had disabled that feature the AMD results would have been between 3%-5% better.
BTW: If desired anybody can search the Phoronix database and get more results that would verify the values of the tests that are in that PDF. These two sets of results were chosen because it is the same version of Linux and the same version of Phoronix.
It is generally a good idea to ignore memory and disk benchmarks when doing a true comparison. (i.e., IOZONE, DBENCH, THREADED IO, BLOGBENCH TESTS.) Especially because of the differences in disk systems. (I.e. some people like to count how many tests are in a benchmark suite and then count how many one "wins" vs "loses" each chip has. But using that simpleton system without consideration of useless comparative tests would give misleading results.)
Wait for i5-750 to drop back to $159.99 at Microcenter if you have one nearby.
Or you could grab a i7-860 for $200 at Microcenter.
Since not everybody has a Microcenter near to them then it is not always cheaper to purchase from Microcenter so you can't really claim those prices objectively. (Yes I've seen several posters on this forum pretty much demand that everybody must use Microcenter.) It would cost me about $40.00 to drive round-trip to a Microcenter which kind of defeats the purpose of "saving".
The easy and readily available average price of the i7-860 is $280.00 and the i5-750 is $195.00
BTW: Here is a comparison of the i7-920 at 3.6Ghz against a Phenom II at 3.6Ghz. (The tester claimed it was running at 3.66Ghz but the testing system's system info said 3.6Ghz.) It performs better in 58% of the non-disk/non-memory benchmarks that can easily be compared. This is not as clear of a "win" as many people claim.
