AMD: R9xx Speculation

Please, keep silent, you're not adding anything to this topic except some complete B*S*

 

Have you seen this:

Perhaps Charlie is doing the same- adding some.....

 

Interesting.

Gone are the days of 3-way or Quad-CrossfireX in the HDx8xx line of products? Or is the single-chip high-end really moved up to the HDx9xx range?


BTW:
Tessellation Unit is still singular. So either left at it's current state or they significantly beefed it up, but from the wording it seems highly unlikely that they've taken the distributed approach Nvidia is so proud of.

 

Charlie is FAR more correct than you have been so far.

 

You don't respect my opinion, do you? I don't care who is more correct and who is not. Because all people are equal under the NDA.

 

Well wasn't it the common understanding that it was triangle setup/rasterization that was holding the tesselator back anyway?

 

Other new stuff: UVD 3, AMD HD3D and HDMI 1.4a.

Compelling stuff.

 

Isn't HDMI 1.4a needed for that Open3D? Nice, so it's here finally. LINK

 

I'm quite curious about the mentioned "Image quality enhancement technology"

UniversalTruth: I think members are trying to separate fake and real leaks. It's not very helpfull to start speculations based on obvious fakes...

 

No, the limitation is in the front-end. Juniper and Cypress are able of one tri/clock. But the front-end is to slow to produce this triangle with tessellation.

 

im sure there were plenty of situations found where cypress wasn't even hitting its 0.8 tri a clock under heavy tessellation.

 

Interesting words, wonder what they mean.

 

I think tessellation was made slow because setup/rasterisation is the bottleneck. It's literally pointless producing small triangles faster, because they'll just fill a queue, which then grinds to a halt.

In other words, without fine-grained setup and rasterisation, increased-tessellation throughput offers no gain.

 

Hi there I'm wondering if there is a connection with this:

Well, GF100's tessellation approach is quite brute force...

While Evergreen is slow, it seems to be connected to something else than the tessellator itself or even the rasterizer/setup throughput.

 

The 3D games part of "HD3D" is already supported on all HD-series Radeons AFAIK?
(Since Cat 10.3)

Transcoding works on any HD-series card, it uses stream processors, not UVD

 

It's quite elegant considering slide below:

 

Do you have a link to the presentation?

 

Nope

 

Barts XT should not be in the 6800 class, that would be epic failure on AMD part....i know its just business but.... the lowest goal i can accept is to call it 6790 and go for 239 bucks. Talk about GPU sloooowdown...

BTW will the HD6 series output audio and video streams separately from the connectors? It is a bit silly to always on ma AVR just to get to ma desktop with HD audio.
