Asus P4T533-C and Intel D850EMV2 in the test: The new i850E with 533MHz FSB


For one This conclusion should of course be about the P4T533-C, on the other hand there is also a final word about the i850E and PC1066 Rambus.

First about the P4T533-C from Asus. The board runs absolutely stable, offers the advantages of the i850E, which e.g. can assign its own IRQ to each component, and has no problems with the PC1066 Rambus. Thanks to the NEC USB2.0 controller, it also offers four USB2.0 ports that the i850E does not provide in conjunction with the ICH2. The design and layout is well thought out and the typical Asus features such as EZ Flash, EZ Plug and Asus Update are a nice addition, which sometimes make work much easier. For less experienced users in particular, bios flashing is an insurmountable hurdle that should be overcome relatively easily with 'Asus Update'. Unfortunately we have to criticize the lack of the important BIOS option 'Fix PCI/AGP Clock'. It is often the guarantee for successful overclocking of thePentium4. The P4T533-C does not offer all the extras that can be installed on a mainboard, but it only costs around 170 - 180 € (retail price still unknown). Every customer who gets by without special accessories such as OnBoard Raid, Bluetooth or Firewire is well served with the P4T533-C and onboard LAN, sound and USB2.0. Direct comparisons to other mainboards are still difficult at the moment, as we were only able to test the P4T533-C more precisely before the release. The comparison to the D850EMV2 shows, however, that Asus has again understood how to get a little more out of the reference design from Intel.

The i850E is certainly a double-edged sword. Nobody really needed it, because it is not a problem to overclock the predecessor, the i850, with an FSB of 133MHz (533 QDR), so that the new Pentium4 can also be operated with 533MHz. In addition, at the request of the mainboard manufacturer, the ICH4 was dispensed with so that they do not have to revise their layout. On the other hand, one must of course also see that Intel cannot release a Pentium4 with 533MHz FSB without one of their chipsets officially supporting it. For this reason, the i850E has its raison d'être again and is a completely logical step by Intel.

Officially even not supported, unofficially but still no problem: PC1066 Rambus. Intel opponents in particular repeatedly speak of a 'castration of the Pentium4' if the memory bandwidth does not harmonize 1: 1 with the bandwidth of the processor. PC1066 Rambus offers over 30 percent more memory bandwidth than PC800. It delivers the optimal bandwidth and performance for the new Pentium4 and also represents the best combination, this is certain. The 30 percent more bandwidth can by far not be used and the overall performance benefitsCut not even 5 percent. If you want to get the highest possible performance from your new Pentium4 with 533MHz Quad Pumped Bus, you will probably rely on the PC1066 if you can buy it somehow. In our opinion, however, one cannot speak of 'castration', as some will call it again in the next few days, in connection with the PC800. But at this point, our benchmarks can speak for themselves and every reader is best able to get their own picture of what to think of the PC1066.
