a3 / b1.
Is that really unheard of? May be they'll rebrand it, but it's hardly something out of the blue.

The big question is when will they release a midrange product. I hope they dont want to rebrand more cards to gt3xx.
Its hard to push DX11 and tesselation with just 2 dx11 high end cards.
Glad to see others are now posting what I did around or a little bit more than a month ago in this thread concering B1 stepping Fermi's.
Well for what it's worth he said a couple months. Timeframes are colliding with your past data and I personally prefer neliz' version of it
It had better, other wise a B2 in August will leave it precariously close to NI. And subsequently push back future roadmaps.
What is your definition of well ?
What is your definition of definition ?
What do you think of my poor spelling.
Will batman and robin escape ?
Tune in next post at the same bat-channel and bat-time !

let's say it's performance is in-line with it's power usage.
So, no it won't use as much power as a 5970 and no, it won't challenge a 5970 as "graphics king."
I don't care about it challing the 5970 . That was silly to think a single gpu on the same process will defeat a dual gpu .
I just hope its fast enough to cause ati to drop prices.
If the B1 comes out of teh oven as good as they hope it does, OC'd versions(factory and user) might challenge the stock 5970 in some cases.

Problem is that when B1 arrives in Q3 (1) it may not fix the issues (2) it will spend it's life up against Northern Islands products.
And B1 is still only a high end product with nothing in sight for the mainstream.
By then the 5870 will be 9 months old and the 5970 would be what 6 months old ? 7 ?
We are already seeing faster 5970s coming.
Right, but it also proves to some extent that my system's not necessarily the limit for Heaven in tessellated mode (which was one of the possibilities where the discussion was coming from).

It's not perfectly related to sub-pixel polys/high overdraw induced by tessellation.640x400 -> 2.19/0.45
1280x800 -> 1.98/0.50
2560x1600 40,4 -> 1.48/0.67
I think it's a serious subpixel polygon size issue caused by tesselation. I don't know which hardware units correspond to that though.
If it were an efficiency loss, framerate would drop as you lower resolution substantially, which I checked is not the case all the way down to 320x200, framerate increases even if it's minimal (when using a GPU capable of 200fps and making it stall for 30ms, halving effective rendering time won't have much of an impact, basically 35ms -> 32.5ms total frame time).
There's an enormous overhead on Evergreen GPUs when tessellation is On, but apparently entirely due to poor dispatch... which could explain why GF100 has no less than 1 tessellation unit per SM and why LDS conflicts appear on Cypress.
I think a workaround for this behaviour could be to dedicate some of the SIMDs to tessellation as that should avoid conflicts.
Hopefully, AlexV or someone else will be able to dig more into it.

Did you even read the what you quoted? How can there be "little to no" product until July even after the launch, but B1 will somehow be available in massive quantities in May?
Same way I called the GF100 launch as being six months later back in October despite other claims to the contrary, I'm calling B1 in Q3, with no guarantee that it's going to fix all their problems.
Considering the battering they have been receiving since the rv770 bomb, I'd guess they'll launch mainstream stuff before B1.
