    VisionTek Xtasy GeForce4 MX 440 Review
    By Vince Freeman :  April 19, 2002

    The GeForce4 MX 440

    The GeForce4 MX 440 is the middle child in NVIDIA's new value lineup, checking in at a default clock speed of 270 MHz along with 64-MB of 400 MHZ DDR. These are some pretty big numbers for a budget video card, exceeding previous GeForce2 MX specifications by a good margin and even outranking the GeForce2 Ti and GeForce3 Ti 200. Of course, pure clock speed, especially of the core variety, isn't directly comparable if the chip and card designs are radically different.

    This is exactly what NVIDIA has done with the GeForce4 MX, and it follows previous MX versions by only featuring two pixel pipelines. Discounting the features comparison until the next section, this makes the modified core of the GeForce4 MX approximately half as powerful as a same-speed GeForce4 Ti. There are mitigating factors as well, and the above is simply in reference to basic pixel processing and some forms of anti aliasing.

    The GeForce4 MX is built on the same 0.15-micron core used with both the GeForce3 and GeForce4 Ti, which means that the combination of a less complicated core design and lower-than GeForce4 Ti speeds make it a cooler running chip. This fits right along with the NVIDIA strategy of designing the GeForce4 MX for the entry-level sector, where expensive cooling designs would unnecessarily raise the end-user prices.

    As with their GeForce4 Ti line, NVIDIA has also introduced three models using the GeForce4 MX core. Each features different core and memory speeds, and in the case of the GeForce4 MX 420, SDR memory as well. Although there has been news of a potential GeForce4 MX 420 DDR card, we'll have to wait until firm specifications are released before confirming it.

    Here is a chart that should illustrate the main specifications of the three GeForce4 MX models:

    Specification GF4 MX 460 GF4 MX 440 GF4 MX 420 (SDR)
    Core Clock 300 MHz 270 MHz 250 MHz
    Memory Clock (DDR) 550 MHz 400 MHz 166 MHz
    Memory Bandwidth 8.8 GB/s 6.4 GB/s 2.7 GB/s
