That's nothing more than a vague interpretation of other forum postings and some rumours.

Obviously fake,Barts XT and Barts Pro won't have the same Z/stencils.

Barts must have inherited GF10X's lovely GDDR5 controller.

The power figures are odd. Why would a 960-shader part draw more than 150W when the HD 5770 only draws 109W at the same clock?

hence the Salt! :P

Maybe some people wish it was only as good as the GTX460.

4000?

I'll take that as a hint…

Positioned against should be read as „handily beats”, shouldn't it?

That part isn't a hint, that's just some self-adulation for his 4000th post.

Congrats, btw

NOW it's a parteey !

Worth noting, too, is that the FUSION-logo just doesn't belong there, especially considering that logo is supposed to vanish along the ATI logo, which isn't present on the slide.

Uhm, most ATI presentations in that black format have the Fusion logo in the bottom left of the slides.

[Jawed]

And the little red squiggle under "perf" means the slide was in edit mode - not as part of a deck that's been handed out. So a slide in edit mode needs cack-handed blacking-out of selected text

Why not? It's Z/stencil per clock, so as long as both have the same number of ROPs, it's natural for them to have the same Z/clock rate.

With only 960/800 SP but a 256-bit interface, even 4.2 GHz would probably be overkill and do little for performance. Why use more expensive 5Gbps memory chips when 4.5Gbps chips are more than enough?


But yeah, I don't buy this slide either. Cypress-based?!

Yeah, but didn't those also feature ATI-logo, which is missing from this one - and Fusion & ATI logos are supposed to disappear at the same point to simplify things.

Mindfury: this slide is about samples per second, while the Barts slide is about samples per clock... you can't compare these values

These values are supposed from the same company.Why one is about samples per second,while the other is about samples per clock?It doesnt make sense.

[thop]

Well whoever leaked the slide isn't very smart. AMD can easily figure out which partner is involved here.

That's of course assuming it's even real, which it starts to look like it's not

This indeed seems to be a rough estimate.

Playing with GPUSA, though, you'll see average efficiency is around 75%, with some insanely inefficient shaders (short and almost purely sequential scalar ops...)

Going 2+2, DP would jump from 1/5 to 1/2 (semi-specialized slots, 2 taking care of the MUL and 2 of the ADD) and average efficiency in SP would go up too.

Add the tessellation issue to the mix (3 times the necessary Ops done) and you're done.


Don't know where the "Barts XT is 700MHz" comes from, but perhaps it's true and they doubled ALU frequency.

It came from nApoleon.But he only said it was 6700 series,and it wasnt the final clock.

Not 100% sure that the above post is the first reference to the 98.5% performance but it is the first I saw. Also I don't ever recall that tempered guy having any sort of inside info... though I am not a member of AT so I can't really review his posts, I do read the GPU forum quite a bit for a laugh.

Was that really the original source for the 4D rumour? Wow, if that was just a WAG he definitely inspired a lot of unnecessary mental masturbation over it. I agree with him on one thing though - something big had to have changed.
