Disk Controller Performance

With so many chipsets and brands of storage controllers on current Athlon 64 boards, we needed a means of comparing performance of the wide variety of controllers. The logical choice was Anand's storage benchmark first described in Q2 2004 Desktop Hard Drive Comparison: WD Raptor vs the World. To refresh your memory, the iPeak test was designed to measure "pure" hard disk performance, and in this case, we kept the hard drive as consistent as possible while varying the hard drive controller. The idea is to measure the performance of a hard drive controller with a consistent hard drive. We played back Anand's raw files that recorded I/O operations when running a real world benchmark - the entire Winstone 2004 suite. Intel's IPEAK utility was then used to play back the trace of all the IO operations that take place during a single run of Business Winstone 2004 and MCC Winstone 2004. To try to isolate performance difference to the controllers that we were testing, we used Seagate 7200.7 model SATA and IDE hard drives for all tests.

iPeak gives a mean service time in milliseconds; in other words, the average time that each drive took to fulfill each IO operation. In order to make the data more understandable, we report the scores as an average number of IO operations per second so that higher scores translate into better performance. This number is meaningless as far as hard disk performance is concerned as it is just the number of IO operations completed in a second. However, the scores are useful for comparing "pure" performance of the storage controllers in this case.

The Sapphire PURE Innovation is a really excellent performer in iPeak tests. The new SB450 turned in some of the highest iPeak measurements that we have yet seen in IDE and on-board SATA. While the SATA controller of the SB450 is not the SATA 2 used by the NVIDIA nForce4, its performance is even faster than nF4 when running our stock SATA drive.

In past benchmarking, IDE has provided the slowest IO performance in this roundup. However, ATI IDE breaks that trend, with IDE performance to be the best that we have measured since we have been testing with iPeak.

Sapphire and ATI have also done an excellent job in implementing the Silicon Image 3132 chipset for SATA 2 performance. The 3132 was blazing fast in our benchmarks, setting new iPeak performance records. For disk storage - IDE, SATA, or SATA 2 (with the Sil3132) - the Sapphire ATI delivers outstanding storage performance.

    This board sounds fantastic!

    Competative with similar Nforce4 boards(DFI LP) isn't enough. They need to beat the price by 5-10 dollars in order to regain the edge. I agree that the VTT options is awesome (for you BH-5 users), but in order to kill the current proven top Overclockers board, they need to be very competative with the DFI in terms of price.

    Also, I was wondering if they managed to fix the cold boot issue with these boards. If the cold boot issue is a non issue with these boards, and they are priced exactly the same as the DFI Lan Party boards, then it is a no brainer for BH-5/CH-5/UTT users as to which board to pick (unless they already are doing the 3.3 Rail Vdimm mod).

    Also, the 2nd page, He art in the first sentence needs to be fixed, and in the first page, it says AMD in the first paragraph when its supposed to say ATI.

    I don't think so, a lot of people complain about problems with the DFI.....and it has a super loud fan on the chipset which is difficult to replace because the video card is right on top of it.

    I personally would never buy a DFI....different people obviously have different priorities

    If this board is rock solid stable like AT reported, then they will have a winner.

    looks like a strong competitor, and here was a typo pg. 11
    "The Sapphire ATI chipset performs at least as fast as the best of nForcee4 chipset boards"
  • Mant - Friday, July 29, 2005 - link

    I think that was intentional. They're comparing the ATI to the "NForcee" by MVidia...like you can compare a Seiko watch to a BOLEX

    In the first pic of the motherboard, it clearly has 8 SATA ports. However, the next page lists the specs with 6 SATA ports and the next picture seems to confirm that. Is there indeed an 8 SATA port version as well?
  • Wesley Fink - Friday, July 29, 2005 - link

    The pictures on page 4 were provided by Sapphire and are earlier prototypes. The actual production version we tested is pictured on page 5 and has 6 (not 8) SATA ports. We apologize for the confusion. There are indeed pads for 8 SATA ports on the production board, so there could be further developments.

    What i like:
    Performance in general
    good audio quality (im wondering if it supports any of the eax extensions though which would be great if it did. Would elimante the need for a sound card.)

    What i don't like:
    bad USB2 performance. This would affect me big time. I have a pro consumer camera (8MP Olympus C-8080) and i usually transfer a bunch of images at a time from my camera to my computer so this is definitly a disapointment.

    I really like nvidia as a company. Their driver team has from the start been top notch. I think that is one of the things that led to their popularity. I generally have always gone with nvidia except in the 9800 pro days because you know why. I currently own a 6600gt which i love. Anyways the only thing that upset me that nvidia did was to take out soundstorm out of thier chipsets. I hope ATI bringing high end audio will force nvidia to reconsider. Nvidia knew that a lot of customers were asking for soundstorm back yet they still wouldn't put it back in. I just don't understand this.

    I hope thier are boards produced that don't have dual video card abilites because of price. I really don't want two video cards. I only occasional play games and im not going to spend 500-900 on two video cards. So we shall see how this plays out.

    The mobo manufacturers were griping about the price. Also, I believe the demand was too low. Yes I know lots of geeks liked it but we're a small percentage of the market.

    "Today, we look more deeply at production version of the ATI Grouper that will be launched by Sapphire next week."
    So, when do we actually see these? If it's by end of Summer, great. If not, it may just be too late. I think most people who've waited for ATI to get this out have already gone to nVidia. I know my buddy has.

    Also, regarding Crossfire, can an AIW X800XT PCIe work with a plain old X800XT PICe?
