... I doubt that. The Geforce 6200 has 4 pipes and I think 3 vertex units.

To find out of the total memory bandwidth just multiply the memory bits to the memory speed for instance 64X500Mhz (For the Gefoce FX 5200) Which equates to:64000 or 6.4gb.

The TNT 2 had 128* the M64 had 64*

The TNT was running at 150Mhz*128 = 19200 or 1.92gb.

On the other hand...

The 6200A biostar card has 533Mhz memory

so 533*64 = 34112 or 3.4112Gb

Overclock that and you might be able to hit the 4gb barrier

My Old laptop with the Mobility Radeon 9700Pro had 600Mhz memory (300mhzx2)

so 600*128 = 76800 or 7.68gb. It used to be clocked at 210mhz but over clocking was the norm to do any decent gaming on the machine.

so if it was 210*2=420*128=53760 or 5.3760Gb. so 2.7gb of added bandwidth just by over clocking from 210 to 300 mhz

The 6200 should play Half Life 2 fine, at medium quality, A friend has a Celeron 2.2 gigger, 512Mb of ram, and a Radeon 9200SE with 64bit memory and is playing Half life 2. And the 6200 Is a much more capable card than a castrated 9200.
