Barend schrijft dat de lui van Thresh's Firingsquad een clock for clock vergelijking van de Celeron II en Coppermine gemaakt hebben. De CPU's bleken evensnel te zijn als de L2 cache uitgezet was en de Coppermine een stuk sneller als het aanstond, wat dus goed aantoond waar Intel heeft geknoeid met de Celeron II:
In the words of Method Man, "Cache rules everything around me, CREAM. Get the money. Dollar dollar bill, y'all." I'm pretty sure he meant cash, but cache works for us. The P3 Coppermine and the Celeron processors performed exactly the same with the L2 cache disabled. The P3 has a larger cache, with higher set associativity, and less latency. One, all, or a combination of all these factors have an impact on performance.
As we can see from the benchmarks, clock for clock, the new Celeron is slower than the Coppermine P3. We also see, however, that the overclocked Celeron processor isn't that much slower. The P3-850E sells for about $900. A Celeron 566 sells for between $150-180 right now, but it should settle in the $150 range once demand dies down.
Just to be fair, lets compare the 566 to the P3-650E, a processor that we've been able to overclock to about 850MHz. You can find the P3-650E for around $300, about double the price of the Celeron 566. You'll also need a good stick of PC133 SDRAM if you want to overclock the P3, not to mention peripherals that are able to function with an overclocked system bus.
Het leuke is dat dit ook gaat gelden voor de Thunderbird versus de Athlon maar dan net omgekeerd .
