PCI 5700 LE 128 mb card....64 or 128 bit memory interface?
 
I know someone who is looking for the best pci video card available. I recommended him either a radeon 9100 or an fx 5600 based upon this review http://www.sudhian.com/showdocs.cfm?aid=445 However I saw this the other day at newegg.

http://www.newegg.com/app/ViewProduc...140-041&depa=0

I can't find any info on this so I am not sure if it has a 128 bit memory interface or a 64 bit memory interface. Anyone know?

5700 Le = 5200 with mor vertex processor to out put mor triangles a second. but with only 1 giga pixel fill rate, all the pollygons in the world will not make this thing render pixels any beter than the 5200. 5600 has 256mb ram and 1.3 giga pixels fill rate. Better choice don't you think.

Not true. a 5700LE is a fully functional NV36 core, just at lower frequency. It's a decent Dx9 card, better than any NV34 core, and a good Dx8 part.

According to NVidia specs, a 5700LE should use 5nS RAM (2x200MHz DDR) and a core frequency of 250MHz. If the GPU is cooled with a fan, it's possible to rise the core frequency almost to non-ultra levels. The NV36, due to the framebuffer compression technology, seems to be less memory limited than other cards.

To know if your card has either a 64 or 128bit bus look at the layout of the memory chips. The TSOP memory chips used have a 16 bit datapath each. A board with 8 memory modules is likely to use a 128 bit bus. If they are only 4, then it's a 64 bit one. Pay attention also on how the modules are arranged around the GPU. If they are all placed at the rightmost end of the board, it is likely it will be 64 bit only. If they're placed around the core in a "L" shape, then chances are that the board support 128 bit bus.

really appreciate your response. looks like this 5700 le is prob the best pci card a person can get. going to recommend the person i know to try and pick it up for his dell computer.

again thanks.

No probs. :) There're so many confusing variants that is very difficult to pick the right one and to avoid all crap circulating in stores.

Probably the GPU Kojiro was referring to is the GeForceFX 5500, which is an updated NV34 core (and the GPU itself is referred by NVidia also as the NV34B)
