For those who usually overclock their processor, there is not significant advantages from passage with FSB 333 MHz from 266 MHz , test proved that at equal frequency the performance between the two processor (266 MHz) and (333Mhz) is in the best case 1-2%. The only positive side with the new 333 MHZ processor are : increase in the specific performance, higher processors frequency with 4 MB cache volume in the second level and finally ALL this is proposed on the previous prices.
Let us also note that new processors energy consumption in the rest state was reduced to 8 W : this noticeable in comparison with 12 W in the previous core revisions (30% saving) , but if we recall that the first processors core consumed 22 W, then the new level is simply amazing. However, as main change for us should be recognized the improvement in the overclocking potential. Overclock to 3.6, to 4 GHz and even higher are submitted daily with new processor , the new revisions noticeably improved the overclock result using air cooling even without increase in the default vcore, moreover this improvement is not only for dual core, but also for four core processors .
To check the overclocking capability , we took three processor intel core 2 Duo e6550. They all work on the system bus 333 MHz, their default frequency is 2.33 GHz, they have 4 MB cache in the second level, ALL those processor are assembled in Malaysia and has the marking SLA9X.
