Little tidbit on ATI's R5xx series cards

Snippets from the story:
Quote
...launch their new architecture, the basis of the R5xx series, in the first half of 2005...

...architecture to be based on Shader 3.0...

...GDDR4 memory technology...designed to scale to speeds of 1.2GHz (2.4GHz effective)...

...90nm...

...move from FP24 to FP32...
Sounds nice...and rumour has it that the guys behind the R3xx series (Radeon 9700 etc) are the ones driving the R5xx series...would be very interesting to see if they can come up with a card with as much impact as the 9700 had when it was first released...

However, I'm a bit skeptical...even with the move to GDDR4 and memory speeds of 2.4GHz etc, I'm not so sure that we will see such a radical increase in speeds like we have seen between the 9700 and X800 cards for the reason that they are moving to true 32-bit precision...32-bit is way more intense than 24-bit and I wonder if the increased memory speeds will only cover the precision increase or if it will indeed pan out to make for much faster cards...time will tell I suppose.

I like the especially vague timeframe..."first half of 2005" :) Prolly means anywhere around May we should be seeing them pop up. Hopefully the supply will be better this time around...seems it's still hard to find X800 XT PE's in stores...same story with the 6800 Ultra's...can't say that I'm too surprised tho.

Take a look at this site:
http://www.hardwarezone.com/articles/view.php?cid=3&id=1071

As far as I can tell when I read about the 6800 before its debeau, it already supports 32-bit  precision.. this article I believe re-enforces that idea.... take a look. If I am not mistaking with what they mean and what u mean, then the answer to whether or not the change to 32-bit will cause overhead enough to negate the effect of GDDR4 would be "no it won' t be a problem".

No no, that's not what I meant :) ...nVidia has been 32-bit (floating point) since the 5x00 series...what I meant is that ATI is finally going FP32-bit...they've been 24-bit for quite a while...but in accordance with the Shader 3.0 spec...they must go 32-bit...

I'm just curious if the move to GDDR4 will only compensate for the overhead that will be increased by moving from 24 to 32-bit...or if it will more than suffice and provide a large improvement over the R4xx series of cards...

Understand now? Or did I lose ya some more? :D

GDDR4 means nothing, the latency would be probably higher than the last series..

Latency may indeed be higher, but they compensate for that by raising the speed...hence they've stated that it can scale to 2.4GHz...
