Nvidia G70 Ultra cancelled

[Toss3]

you have to know better than that.512 Mb cards show performance increase when running memory hungry games that need over 1.5 GB to run smooth with max detailed textures.

BF2,EQ2,FEAR are good examples and you can expect more games like those to come out in future.
Umm I found some F.E.A.R benchmarks done on a 512mb version of the x800xl and it showed that the 512mb card made no improvement over the 256mb edition, this may of course be due to the fact that the card would be too slow to take advantage of the extra 256 mb, which brings us to my point: the 6800's and the x800's are still too slow to take advantage of 512mb, that's why I was wondering if the 7800gtx would benefit more from 512mb than the 6800Ultra benefitted from the extra 256mb ddr3? (I couldn't find battlefield 2 benchmarks run on the 6800ultra 512 mb ed. :( )

Edit: Oops those benchmarks were run @1280x1024 with no AA and without any AF :o But could someone here direct me to a benchmark showing a 6800Ultra benefitting from the extra 256mb?

A 512mb 7800GTX should definetely come out... dunno if we will see much more than that until next year :)
It already has the Leadtek one http://www.leadtek.com.tw/eng/3d_graphic/overview.asp?lineid=1&pronameid=219

It says 256mb when clicking the specifications tab! :)

It says 256mb when clicking the specifications tab! :)Yea that's a mistake it is 512 mb

Says 256MB in this review and on the box?

* 256-bit memory interface
* 256MB Graphics DDR3 SDRAM (1.6ns)
* Default clock rate of 625MHz (effective speed of 1250MHz DDR)

A lot of us are still waiting for a 7600 GT.That's the effect of the recent lack of strong products from ATi. I'm saying this because some people overjoy when one vendor or the other fail to deliver.

In the end it's us customers who are hurted.

Anyone remeber 1999 ? With no less than 5 big players in the arena the prices fell in matter of weeks and there wasn't a month without a new product being launched. If we also compare the prices of high end parts in '99 we would discover that they were half what they are today. Funny, no?

It's already out. It's the 6800GT.

yeah there wouldn't be much point in a 7600gt. are they actually making one?

I think they will, once they clear the backlog of 6800GTs. The NV40 is a big die, and I'd imagine an equivalent performer at the 90 nm level (which is what I'd guess the 7600 GT would be) would be cheaper to produce, so margins would be much better. That's just a stab in the dark though, and who knows whether I've hit truth or fiction.

512-bit bus :wtf: .. i think adding more ROPs would be easier than the transition to 512-bit GPU.

at first i too thought a 7800U will come later & just boost the core/mem speeds , but i think nVIDIA already learned from thier 5900U & 5950U refresh mistake & thats why they didnt repeat it with the GF6 series like you said even though ATi went ahead & did it again . (9800Pro -> 9800XT , X800XT-> X850XT).

so this round could be the same & nVIDIA hold the 7800GTX as thier highest-end till the end of this year or move directly to the G80 next year.

Easier to add more ROPs, ya. But what would more ROPs do for performance? Games are becoming more and more shader bound. 16 ROPs are more than enough currently. So, when faced with the decision of more ROPs or more die space for other logic, I wouldn't necessarily choose to add more ROPs.

I still like the idea of a 384-bit memory bus :firedevil

Could even say that a 384-bit memory bus goes with their Power Of 3 PR (128-bit x 3)

As for the unbolded part, I agree.

Sure games are becoming shader bound, but for the most part fillrate and bandwidth are the limiting factors. Adding more ROPs would net a nice performance gain with heavy AA enabled.
