RV770 has 800 SP's!

This is interesting as pretty much all of the major tech sites have been stating 480sps for quite a while now.

I wonder if this is 800 'marketing look our number is bigger than yours e-peen' shaders or 800 proper shaders?!

I am looking forward to benchmarks though.
 
Sounds good, but if they havent changed the arc then NV only needs like 10sp's to beat it lol, maybe the 4870 will be a pretty fast card afterall.
 
so hold on a second, RV770 can do 1.2TFLOPS? which is what 0.25 more than NVIDIA supposed offering, how many SP does the NVIDIA card have, its <300 isn't it supposidly? if thats true NVIDIA SP are so much better than AMDs :confused:

Edit: just looked at 'official spec' thread and it says NVIDIA card has 240 SP and can manage a shave under 1TFLOP, how the hell have they managed that with such a smaller number of processors?
 
Prolly still a case of divide by 3-4x to get actual performance against an nvidia card... (and yes I know the old number was taken from x5)
 
I wonder since the clocks are seperated this time (apparently) if we can overclock the ati shaders?

ATI's shaders work completely differently to Nvidia's, don't go on numbers alone, you need to look deeper than that.

The shader designs are completely different. One Nvidia shader can do one operation fast, whereas an ATi shader can do upto 5 operations depending on what it is doing, but does them slower, so if it can only do 1 or 2 operations then it comes off worst. But if ATi can boost the clocks it will give them an edge.

yeah isnt this the same thing as the last card that supposedly had more than nvidia but it was the way ati and nvidia counted them differently

Not really, the two designs are very different. Simply put, AMD's shaders can 'do' more, but they're more complex which means they're not as efficient as they could be, nVidia's shaders are of a simplistic design, so they're quite efficient, and they're clocked really high.
 
yeah thats what i meant, really they have 160 shaders but each are capable of 5 operations so they counted them as 800 in total.

the 2900xt had the same type of thing didn't it? so many shaders but each could do more operations so they counted them based on the total operations it could perform.

It goes back to the "VLIW" architecture. If the game in question takes advantage of VLIW, the ATi cards really pick up serious speed.

But if it doesn't, in some cases the ATi cards can end up dropping back a whole generation.
