Question

Help answer this question below.

In terms of MegaHertz (in CPU rating, and also the motherboard speed), the AMD processor platform is much slower than the Pentium IV counterpart, what does this mean in terms of speed and performance in relation to gaming and frame rates?

    In comparing the speed of a set of processors, e.g. Intel's P4 or AMD's Athlon (the most commonly compared CPU's, PC-based), the MHz rating is not a determination of speed. A Hert, as completely concerned with a definition apart from the already associated technological point of view, is a unit of frequency equal to one cycle per second, not necessarily speed-based. In CPU speed, the term "flop" is used as an abbreviation for "floating point calculation". While not commonly used, gigaflops are used to determine the calculations per second that a processor can make. Of course, this isn't necessarily the best determinant of speed in AMD's case.

    AMD's new platform of 64-bit processors can compute larger amounts of data in the same time. While the calculations might be the same speed, the beefiness of the equations can be increased without lag.

    To determine the best possible performance in gaming, however, the largest, most significant portion of determining speed is not the processor, but the video card (assuming 3D gaming). While the data needs to be moved from the hard disk into RAM, and sent to the video card for processing, the CPU's performance comes secondary to the video card. Obviously though, an extremely slow CPU will not offer up the best framerates, either.

    In summation, AMD's platform when compared in MHz is not slower than Intel's, just because of the differences in MHz.
