Next NV Infomania

Most people here don't see SS as a reliable source.. especially since he mentions the 2x256 bit vs r520's 512 bit memory bus

 

More classic Inq - http://www.theinquirer.net/?article=24008.

 

Well retailers here in Australia are starting to advertise the 7800GTX (Sparkle brand) for 840 AU$ and specs are for 1400mhz memory speeds.

 

I wonder how many here will own up to their mistakes and errors next Wednesday? Or are silly season errors to be forgiven? If you ask me, maybe Hieronymous Bosch had this whole thing figured out 500 years ago.......

Are you referring to being off with speculation/guesswork or people who are claiming facts?

 

How did he render that movie-like effect?

 

Well....both! There seem to be many that can't tell the difference between speculation and fact.........

Although I have to admit it's fun to watch and see just what is gertting pulled from where....... I'm sure nV, ATI and those that get paid per hit on websites* just love this stuff!

*but it won't replace p0rn.........

 

I need a noise filter when the reviews hit the web.

 

You always need one of those, they are extremely handy

 

You can do what I do....put my fingers in my ears and yell La-la-la-la-la-la-la-la-la-la-................

They will change the bit rate according to the frequency of the ram to meet this bandwith. can be anything between 128 and 256 bit.

 

You are fast kid! But not as fast as I am. Heh heh.

 

I work for an Australian retailer. The distrubutor doesn't have any stock yet. Apart from price and when they expect stock, all they seem to know about the card is...

Model: SPPX70XVH/256
Sparkle pci express 7800GTX 256MB 2xDVI + VIVO

Seems to be pci express only for the time being. Suprisingly cheap though imo, this should mean something. (more to come? ultra?)

 

In France a few hundreds cards will be available on launch's date

 

If I understand correctly, FP rendering is mostly bandwidth-bound in the current implementations. Given the relatively small boost in bandwidth on the G70 and Nvidia's heavy marketing of FP rendering, what else could they have done to make HDR more accessible? Or am I totally off and the additional pipelines and efficiency improvements will help with HDR rendering too?

 

Presumably NV40 was optimised for a conventional lossless compression 4-byte colour + 4 byte z/stencil architecture.

I suppose if the compression architecture of G70 was re-jigged to include 8-byte colour, it could gain speed/efficiency over NV40.

Separately there was a brief mention somewhere of G70 having more efficient texturing, which as a side-effect would presumably free-up bandwidth for FP blending.

It might turn out that NV40's texturing engine was not really designed for FP16 textures - it was merely capable, rather than optimised for. If that was the case, we might also see a big leap in filtering FP textures.

I dunno. I expect we'll get quite specific information on these points this week
