Question, How is the NV30 going to have more bandwidth then the R300?

We know that the NV30 only uses a 128 bit bus where as the R300 uses a 256 bit bus. We also know that the NV30 will be using 1Ghz memory which unless they brake the pattern they have established since there first DDR board is really (500 * 2 = 1000) which is a major improvement over the (325 * 2 = 650) that the 4600 uses now. Coincidently this also goes in line with the (500 * 2 = 1000) that ATI stated DDR2 would start at.

This means that the NV30 will have:

(((500 * 2) * 128) /8) /1024 = 15.26Gbs of Bandwidth

Where as the R300 already has:

(((310 * 2) * 256) /8) /1024 = 19.37Gbs of Bandwidth

As far as bandwidth is concerned the picture gets even worse for Nvidia if we take a R300 equipped with DDR2 into account. Such a board would have:

(((500 *2) * 256) /8) /1024 = 31.25Gbs of Bandwidth

As far as over all performance is concerned these numbers don't tell us Jack since the NV30 will most likely have much better bandwidth utilization then the R300. Though if it will be enough to overcome the R300s raw bandwidth advantage has yet to be seen.

What Nvidia really has to worry about is the fact that ATI is working on GDDR. That is supposed to be better than DDR-2!

Almost makes me regret the perchase of my 9700 pro :( NAAAAAA


LoL I feel your pain!!! Oh well I love my 9700 pro. It will still be top dog for a few more monthes hopefully : ). Im so happy that ATI is stepping out with a lot of good cards quickly. GO ATI!!!

the nvidia camp has been very quiet lately... it wouldn't shock me if they popped something completely unexpected out of the hat to completely own ATI.

i can't imagine nv30 is all nvidia is working on.

Im sure its not all there working on, but it is the next think thats coming out. The reason I think Nvidia is being so quit is what are they supposed to talk about? There next video card is 2-4 months away depending on who you talk to, and most likely wont have any features that the R300 doesn't have. So what are they going to do say "Just wait 2-4 months and well have one just as good!" I'm sure there stock holders would love that

since when were they VPU's? ... aren't they GPU's? unless people can just make up names for components.

i suppose "GFGH" would be good for the CPU. lol, Goes Fast Gets Hot.

I think Nvidia will come out with a faster geforce4(?ti 4800?) before it launches its nv30! They can't just do nothing, Also I think Radeon will probably release something else again, could be a cheaper version of there 9700 - Now I think that would boost there sales ALOT!

I wouldnt be surprised if we see the Radeon9700 Pro get a boost and they call it the Radeon 9800 Pro with DDRII technology and .13Micron technology which they promised they'd release by Christmas. I guess we will have to wait and see what ATI has for competition against the NV30.

Don't feel bad about your 9700pro. The limiting factor now isn't the card it's the CPU in your comp. Your computer can't squeeze enough juice through it to use the cards full potential. So even if you do get a faster card. You be any better off than the 9700 pro. Which btw is not a bad place to be at all!

they are already doing that it called the 9500 and the 9500 pro that is about the same as a ti4200 and ti4400 kinda inetween from the benchmarks at anandtech

Nvidia first called a video chip GPU when the Geforce256 was released as a marketing thing and now ATI with the 9700pro started to call they chips VPU (Visual Processor Unit) to differentiate them of the Nvidia GPU´s wich by the way it means Graphic processor Unit.

PS: sorry but what does lol actually means? as you can see english is no my native language
