An MX with a catch ..

On the previous page  I said there is a catch with this product. There really is .. When you go to the shop to pick up your soon-to-become mighty GeForce2 MX videocard you look at the box right ? Now, all other boxes show 32MB SDRAM while that nifty black box from Creative says "32MB DDR" for about the same amount of money you are almost positive that the Creative is a far better choice because hey .. it has DDR memory and the Guru once said that DDR is good !

Okay here we go, what Creative Labs does not print on that box is that this memory is 64bit DDR memory and not the 128bit memory modules as we all know ! Basically the speed of 64bit DDR memory is about as fast as the plain good ol' normal 128bit SDRAM. Don't get fooled by this tricky issue. Let's look into the technical aspect of this shall we ?

The memory frequency of Creative 3D Blaster GeForce2 MX is running at 286MHz (143MHz DDR) and that is the nominal frequency for 7ns chips. Compare this with the memory bus bandwidth of 3D Blaster GeForce2 MX and that of standard graphics cards based on NVIDIA GeForce2 MX, we will get 2288MB/sec for against 2656MB/sec, correspondingly. Let's make a simple calculation:

((2x64bit) x 143MHz) : 8bit  = 2288 MB/sec

I hear you say, what !?  Now let's check out a standard SDRAM GeForce2 MX shall we:

(1x128) x 166MHz :8bit = 2656 MB/Sec
