440BX Performance Page

Updated 06/23/98:

We hope to gradually fill this page with information about the performance of the 440BX chip set. Hopefully this information will be useful to you or at least interesting.

The 440BX is Intel's latest PCIset, replacing the 440LX and 440FX PCIsets. The 440BX has the following features:

  • PIIX4 PCI/ISA North Bridge with Ultra DMA 33
  • PIIX6 PCI/ISA North Bridge with FireWire (1394), UDMA 66 and I2O (Fall 98)
  • 66MHz to 100MHz memory bus speeds
  • Accelerated Graphics Port
  • SDRAM Support
  • Dual Processing SMP
  • Support for 233MHz, 266MHz, 333MHz, 350MHz and 400MHz Pentium II processors.
  • Probably the most important features are the 100MHz memory bus speed and the support for 350MHz and 400MHz CPU's. Note the previous 440LX chip set only supports a 66MHz memory bus speed and CPU's up to 333MHz. The memory bus speed is particularly important as modern day CPU's are starved for data and waste many idle cycles waiting for data to be fetched from RAM. The 440BX defaults to a 66MHz bus speed when used with a 333MHz or slower Pentium II processor. It only uses the 100MHz bus speed for 350MHz and 400MHz processors. At 66MHz normal 10ns SDRAM is utilized. At 100MHz special PC100 certified SDRAM is specified by Intel. However, many vendors have found that normal 10ns SDRAM works just fine on the ASUS P2B 440BX motherboard running with a 400MHz processor and a 100MHz memory bus. They have even claimed that the cheaper 10ns SDRAM has no performance penalty. This is not the case. We concede that the standard 10ns SDRAM appears to work fine on the 100MHz bus. We have been running Linux and Windows NT with normal 10ns SDRAM at this speed for over two weeks without any stability problems. However, the performance is not as good as the same system running PC100 SDRAM. Let's look at some Stream results.

    Chip Set and Processor RAM Transfer Rate MB/S
    440GX 400MHz-512K Xeon Fast PC100 SDRAM 336.1738
    440BX 400MHz Pentium II Fast PC100 SDRAM 307.1459

    440BX 400MHz Pentium II Slow PC100 SDRAM 263.6705
    450BX 400MHz-512K Xeon EDO 4-Way Interleaved 258.6062
    440BX 400MHz Pentium II Premium BX SDRAM 255.8955
    164LX 533MHz Alpha 21164 10ns SDRAM 239.8447
    440LX 266MHz Pentium II 10ns SDRAM 174.0
    Tyan Tiger 400MHz*** Fast PC100 SDRAM 149.6685
    440FX266MHz Pentium II 60ns EDO RAM 98.3

    We used Stream under Linux to test memory I/O. Our test setup for the 440BX included a Pentium II 400MHz CPU, 128MB's of SDRAM, two BusLogic 958's, a 3COM 3C905, Matrox Millennium II PCI video card (with Xi Graphics AX Server under Linux ), SB64 PnP and miscellaneous SCSI devices. Our test setup for the 440LX and 440FX included a Pentium II 266 CPU, 128MB's RAM (SDRAM for the LX and EDO RAM for the FX). The other devices were identical to the 440BX setup.

    The PC100 SDRAM on the 440BX with a Pentium II 400MHz processor was the fastest by far and even faster than the 533MHz Alpha LX system. Standard 10ns SDRAM was stable but over 10.6% slower than PC100 SDRAM. So called Premium BX SDRAM sold by many vendors as BX compatible (but not PC100 certified) was even slower than the standard 10ns SDRAM. However, clearly memory intensive applications will get a huge boost using any of these types of SDRAM with the 440BX chip set.

    The results of the 400MHz 440BX test machine are much better than anything posted for the DEC Alpha family, the SUN Ultra2 family or the HP 9000 series. You may want to compare these results with the Stream results table. The Stream results table compares Stream results obtained on a wide variety of architectures.

    You may have also noticed that we have "slow" PC100 SDRAM listed in addition to the "fast" PC100 SDRAM. This is less expensive SDRAM that is about 16.5% slower than its more expensive cousin. We should note however, that the less expensive "slow" PC100 SDRAM is still PC100 compliant and is not of a lower quality. The slow memory is stable, all memory addresses check out and it is brand named. The only difference is the speed and the price tag. The slow PC100 SDRAM may be a good choice for folks on a budget who want a 440BX board with compatible PC100 SDRAM. This leaves an easy upgrade path to a high performance system down the road. In contrast, those looking for servers or workstations that are data intensive should probably take the leap and buy fast PC100 SDRAM.

    ***Note that the Tyan Tiger 100 (S1832DL) performs at about half the speed of the comparable ASUS and Intel boards when JP2 is set to factory default. JP2 is undocumented. Removing JP2 sets the queuing depth from 1 to 4. When removed this board benchmarks nearly identically to the other 440BX boards in its class. This may have been the cause of the bad review on Tom's Hardware guide.

    Molecular Dynamics Results 

    MDBNCH: A molecular dynamics benchmark is an excellent benchmark for those interested in scientific calculations in general and molecular dynamics in particular. We used MDBNCH to compare our 400MHz 440BX configuration (as noted above) to our reference 440LX 266MHz machine.

    Chip Set and Processor CP SECONDS
    450NX 400MHz-512K Quad Xeon 4-Way Interleaved EDO   13.950001
    440GX 400MHz-512K Xeon PC100 SDRAM 13.959999
    440BX 400MHz Pentium II PC100 SDRAM 14.420000
    440LX 266MHz Pentium II 10ns SDRAM 21.550001

    The results of the 400MHz Pentium II on the 440BX chip set are on par with the 333MHz DEC Alpha, the 200MHz Sun Ultra 2, the 266MHz PowerMac G3, and the Cray T90. You may want to compare these results with the MDBNCH results table. The MDBNCH results table compares MDBNCH results of obtained on a wide variety of architectures.

    This system uses 8 bytes per DOUBLE PRECISION word.
    -------------------------------------------------------------
    Array size = 3000000, Offset = 0
    Total memory required = 68.7 MB.
    Each test is run 10 times, but only
    the *best* time for each is used.
    -------------------------------------------------------------
    Your clock granularity/precision appears to be 3 microseconds.
    Each test below will take on the order of 266046 microseconds.
       (= 88682 clock ticks)
    Increase the size of the arrays if this shows that
    you are not getting at least 20 clock ticks per test.
    -------------------------------------------------------------
    WARNING -- The above is only a rough guideline.
    For best results, please be sure you know the
    precision of your system timer.
