Pentium4: 800 MHz and 533 MHz FSB CPUs Compared

<A HREF="http://www.gamepc.com/labs/view_content.asp?id=pentium4c&page=1&cookie_test=1&bhcp=1" target="_new">GamePC Article</A>

<b>Notes</b>:

* 800 MHz FSB Pentium 4 chips at clock speeds of 2.4, 2.6, 2.8, and 3GHz - classified by the "C" variant in their name (i.e. 2.6C, 2.8C, 3.0C). All with Hyperthreading enabled.

* All at 1.525V core voltage level except the 3.0C GHz processor which runs at 1.550V.

* Changes made to retail box cooler.

* Canterwood chipset can only run memory at 400MHz with 800MHz FSB CPUs. You're limited to 333MHz or 266MHz speeds for 533MHz FSB CPUs.

* Impact of adding a higher FSB and Hyperthreading dependant on application.

* If you already own a 533Mhz FSB Pentium4 then there is no compelling reason to upgrade to a 800MHz FSB Pentium4.

* Despite their high FSB, these new "C" chips are surprisingly good overclockers - extreme cooling not required.
