That is because Phoronix tests are compiled with GCC, the benchmarks used on the gaming sites (which just FYI Cinebench just got caught cheating, 30% bonus hit for any AMD chip over Intel thanks to the flags they used on the ICC) is using the Intel Crippled Compiler which has been designed from the very first release to DISABLE any and all SSE functions on any non pushed Intel chip. They have been doing this since 2005, have admitted they are doing it, and still no sanctions by DoJ. Again the DoJ proves they are absolutely worthless and might as well not exist, as they have been bought off since the MSFT trial ended in 03.
BTW before any of the fanboys chime in with their "herpa derp, Intel knows how to compile better for their own chips, derpa de do" I have 2 words for you.....Pentium III. When the ICC was released every benchmark was showing the P3 curbstomp the P4 by as much as 35%, ICC gets released, Intel throws money at benchmark sites to use ICC and...wadda ya know, P3 is suddenly losing to the exact same chips they beat a year before isn't that amazing? You can also go buy yourself ANY Via CPU, change the CPUID from "Centaur Hauls" to "Genuine Intel" and .......gasp! Suddenly the exact same chip scores nearly 40% higher than the previous run, all thanks to the magical CPUID!
The fact that GCC magically puts out code that paints a VERY different picture ought to give you a clue guys, its hilarious that you scream when companies like Comcast manipulate your Internet to push you to use their services yet here is a company that has gone on the record stating flat footed they are manipulating the market which not only kills competition but makes YOU pay higher chip prices (as if the benches weren't rigged Intel's actual performance numbers wouldn't be high enough to justify the cost and they would have to lower prices, a win for the consumer) and what do you do? Defend the corp raping your wallet.
Rigged markets are bad for everybody BUT the corp doing the rigging, its bad for competition, bad for consumers, and bad for the market as a whole. I don't care which chip you like the fact that a corp is getting away with such blatant rigging? Ought to piss you off!
