Like the Biostar TP45 HP, the ECS P45T-A uses only four of the chipset’s six PCI Express lanes to support two onboard controllers and two x1 slots. ECS chooses the RAID-capable ICH10R however, getting another leg up on at least one competitor.

ECS’s single eSATA port gives it a lead over Biostar and ASRock products, but lacks the IEEE-1394 FireWire controller and digital audio connectors offered by ASRock. The legacy serial communications port of the P45T-A is out-of-place on any modern motherboard, but the six analog audio connections are still viable.

JMicron’s JMB361 controls the Ultra ATA 133 and eSATA ports, using a PCI Express interface to support up to 250MB/s bi-directionally.

The tiny Atheros AR8121 Gigabit Network controller also uses PCI Express for peak performance.

Realtek’s ALC883 is rated at a reasonable 95db signal-to-noise ratio, and we’ll try to confirm that rating in our audio quality tests.

    51 pages... You won't be upset if I read just the last 3 pages right?

    I suppose I can get some good from having read this. Did you get paid by the word? Maybe next time you could just put together a complete features chart so that we can have some convenient comparison? You know, so someone could go to a chart and see at a glance which boards had eSATA or firewire, or 8 USB.

    I'd rather have the overabundance of information than a lack of information. Presentation could use a little refining (I.E. comparison charts and the likes), but having the relevant information available at least is a good thing.

  • the introduction and specifics are nice, the comparision isn't. so, why don't you test with an 8500 or qx9650? 6850 are outdated... and a mobo handling a c2d doesn't mean it can handle a quad too, see P5K for example (it stinks when it comes to a q6600).

    Tom's Hardware wants the performance of current articles to reflect that of recent articles, so a "standard test platform" was chosen a while ago. It will get updated, but probably not before the new socket becomes widely available.

    I would have liked to see something such as a P35 and an X48 as controls to help analyze the P45 Performance.

    In otherwords, What is the P45 Gaining me over the older P35.
    What would I gain by going to the X48. (Or Lose)

    The first 17 pages were filled with nothing but junk from ASUS. Do us a favor: don't even bother featuring or *MENTIONING* anything for any reason from a company that refuses to RMA 200-400 dollar brand new motherboards with anything other then used and usually broken junk. It destroyed my enthusiasm for the article.
