Simple question, tough answer to find definitively.  Isn't the difference that 603 is 400MHz and 604 is 533MHz?

The old type of xeon socket was the Socket 603 and now it is changing to Socket 604.

Newer workstation/server motherboards will come with 604 pin Sockets. But it is backwards compatible. You can install an old 603 pin CPU to a Socket 604 motherboard. But if you want to buy a 604 pin CPU, make sure that you buy a Socket 604 motherboard.

Intel E7501 chipset, formally known as Plumas 533, for Intel Xeon (Prestonia) was released on November 18th, 2002. Plumas 533 is the 533Mhz FSB capable version of Intel's E7500 Plumas chipset, providing support for Prestonia B. This chipset is identical to the E7500 apart from official support for a 533Mhz FSB speed, the support of Socket 604 and DDR266 SDRAM . Plumas 533 will use the same ICH3-S South Bridge as the E7500. It should be noted that Socket 604 is backwardly compatible with Socket 603.

Intel Xeon (Prestonia B) 2.0, 2.4, 2.6 & 2.8Ghz were released on November 18th, 2002. These CPUs have a 533Mhz FSB and are manufactured for the Socket 604 platform (previous Xeons used Socket 603).

The biggest reason I can see for the new socket 604 is so a socket 604 processor can ONLY be put into a board that supports 533.

great, thanks.   Also, can you tell me: are the heatsinks the same size?  I am having trouble finding an assortment of XEON specific HSFs.   If I could use a simple s478 P4 HSF it would be much easier.

Honestly, I don't know if the xeon heatsinks are the same as P4 or not.  I've never actually built a Xeon machine, we instead spend $30,000 for Dell to do it, lol.
