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
