Time for another GPU battle
Tuesday, April 13, 2004 | Permalink

Interesting times are ahead of us. Another generation of GPUs are just around the corner.

As many of you may know, the NV40 is according to rumors going to be presented later tonight. Maybe around midnight some say, which would be early morning for us in Europe. It will be interesting to see what this beast can manage. Some info has already leaked out, but the reviews due tomorrow will certainly be an interesting read. Some photos have also hit the net. It seems that the dustbuster story will be repeated. One can only hope there will be more silent versions around.

In another couple of weeks the R420 will also be presented. Not as much information has leaked about it, but it seems to be quite a beast too. Recent rumors say it's a 16 pipeline badass, but as we all knows, the battle will not take place in technical PR numbers but in the benchmarks. And for us who write our own apps the feature battle will be just as interesting if not more.

Bring it on!

Now the question,

Which one will you get Humus? Both?

Congradulations on you getting your work permit, does sound strange you have to get permission to work you know. Take care and may Yah be with you.

Well, since I'll be working at ATI I'm likely to be playing with the R420.
Well, not sure it's so strange to require a work permit. To my knowledge, it works that way in pretty much every country. You can't just move there and start working as a foreigner. I wish you could though. I'm of the opinion that we should work towards removing all country borders in the future.

Seems like one heck of a card, will be interesting to see if ATI can outdo nVidia this time too.

In any case, I'll go for whatever offers the nicest performance at the best price

Now repeat after me: Competition is good, competition is good

This is a nice little pre-something-or-other about the NV40.

Question for mr. Humus,

Is it better to wait for Ati to release their next FP24 card with VS/PS 3.0 support? Their current FP24 cards run twice as fast as any current FP32 cards in VS/PS 2.0 shader benchmark.

Would FP24 compromise image quality running long shaders (100-1024 instructions like in Nvidia cards) due to roundoffs, etc.? How severe?

The demos in this Nvidia literatures show severe artifacts (nose and shoe demos) rendered with FP16. By the way, what are these artifacts called?

Now, I am curious how FP24 would fair for these demos :?(. I search everwhere for these Nvidia demos but can't seem to find them :?(.

Humus, do you have a similar demo that would showcase these artifacts rendered in FP16, FP24 & FP32? I look for similar 3rd parties demos. No luck. Could you make one if you have time? Thanks

PS3.0 requires 32bit throughout the pipe (although not IEEE)!
