Never thought of that way. Anand is definitely >biased in his reviews then. The reason I say this is the same thing happened to Tomshardware. He made the P3-1.13GHz issue (some chips being unstable) public. Intel told him he was wrong and to retract the article, Tomshardware did not. Eventually Intel had to face the fact that the chips DID have problems and were recalled/replaced. However, due to Tomshardware not removing that article (which gave Intel bad publicity), Intel completely left Tomshardware out of the loop on the P4 launch. They sent him no chips, not even an email. Since then of course, he has rekindled his relationship with Intel and has no problems displaying piles and PILES of P4 chips in his article pictures, smashed Athlon XP cpus, and making a mockery of AMD. >>One of the reasons they don't use DVD2AVI in the encoding tests.
