AMD: R9xx Speculation

[Mianca]

Unless Barts XT is faster than Cypress XT but I kinda doubt that.

Maybe it's about as fast?

Maybe it's about as fast?

But then, why is it positioned against so weaker card like GTX460?

Link.

Awesome achievement in Perf/mm² and (slight) enhancement in Perf/W over Cypress XT if true ...

Moreover, notice the interestingly new shader counts in the chart I linked above?

AMD marketing seriously deserves a "medal of advanced smoke generation" ...

Looks quite promising but we will see.... soon...
Antilles looks like really two times Barts.

the correct link

And what exactly will the performance difference between Cayman XT and Antilles be? 5%, 10%?

Forget about that chart, guys. It's one member's personal speculations. It's not based off of any leaks.

A better question would be why is there only one Antilles? I thought there was supposed to be a Pro and XT Antilles.

It certainly took some balls to post completely different numbers when everyone is discussing whether Barts XT has 960 or 1280 shaders etc. ...

Makes me wonder.

Exactly, I was earlier thinking about ~500$ for Antiles Pro and ~600$ for XT, add ~50$ if tweakers.net prices are correct.

IMHO, a fake.

It doesn't take balls. Just a keyboard and an internet connection

They are just my ideas, written in notepad.

Can't say I find that chart credible at all. Would be nice in most regards if true, the exceptions of course are Antilles being Barts x 2 and Juniper being renamed to 67xx. I don't wish for either of those to become reality.

It indeed says that Antilles = Barts X2, but drivers say Cayman

On other things, what are the chances that Juniper has been updated at least with HDMI 1.4? Since the hardware can do 3D anyway

Also, does 1680 for example split with 4D VLIW?

edit:
scratch that, as it's fake

Nice ideas mate, but I almost had a stroke when I saw 450$ for the Cayman and 275$ for Barts. lol

 

[Alexko]

Official slides say Cayman has 6GT/s memory, and just 1GB of it. So this is almost certainly wrong.

EDIT:

They are just my ideas, written in notepad.

Well that settles it!

Clusters of SIMDs arranged in 2 or 3 blocks versus a single stack as in the squarer Juniper & Rv770 die.

Juniper had a rectangular look too :

that suggests Cayman could be rectangular too .
