I was hoping to buy a AMD HD 6990.
Over clockers stop stocking them though.
So I am now waiting for the AMD HD 7000 series , people are saying around late November to early December at the earliest.
March at the latest , what do you guys think ? I was reading this article and found it interesting.
It says the new cards are planed for 2011.

The specs if you don't want to click the link.

Specifications of Radeon HD 7900 series graphic card

Radeon HD 7900 series will have XDR2 memory which is twice faster than GDDR5
Radeon HD 7970 will have 2048 shader cores, 128 texture units and 64 ROPs
Radeon HD 7900 series will have an TDP of 190W
Radeon HD 7870 will be powered by the Thames XT GPU
Radeon HD 7900 series will use 28nm transistors

Problems in the development of new nuclei could lead to a delay in getting these new cards on the market.

------------------------------------------------------------------------------------------------------


The AMD 7900 series will have liquid chamber cooling so this link says.

Is this a good or bad thing ?

Those specs don't seem *too* far fetched, other than I'm sceptical about the XDR mem...

I can relate with you there, a lot of promises are made and then broken.
a guy was hyping the crap out of the AMD bulldozer to me , and it was a flop, but maybe it will be relevant as a processor when these new cards come out...
and software is better optimized for that architecture ?

Anyway my point being. I agree with you and am also skeptical about this new XDR memory.

Bring em on I could do with replacing my xfire 6870's and would love some new gen cards:)
 
All info suggests that AMD are taped out, ready, everything's pretty hunky-dory they are just waiting on TSMC being ready.

Early-mid december being the earliest, the latest will be, probably mid Jan, not March, not a chance in hell for March UNLESS TSMC have a major process screw up in the next few weeks, which is unlikely as they've said they've shipped finished wafers and news of a HUGE issue would have been announced by now almost certainly.

High end most likely first, midrange next and I'd put it within a month though capacity problems could delay that, high end is VERY low volume compared to everything else, midrange will sell a heck of a lot more cards and have a heck of a lot more demand.

My guess for Nvidia, for real Keplers(seems a bunch of 610-630gt's will be out in not too long, 40nm mobile parts) I'd be thinking midrange first, earliest of late Feb-March, and high end seems destined for April-June based on current info, maybe 6-8 weeks later than that if it needs another respin. This could be Nvidia keeping a very tight lid for a change and surprising everyone but their history of high end on new processes has been poor for pretty much the last 5-6 years with almost no new high end on a new process for ages. 280gtx on 65nm when 55nm was basically just starting, took them an age to get to it with 285gtx and it was a very minor shrink(about 20% smaller). The only two none late high ends they've had were 285gtx and 580gtx, and both were on established processes. History suggests mid next year sounds right, potential for hilarity and good competition means I hope it pops up out of nowhere in Jan 2012 but with Nvidia around it could also be another Fermi style screw up and end up with us closer to Jan 2013 which would still be funny.


Back to AMD, XDR2 is more possible than people think but not altogether likely, what people might be missing is that it might SUPPORT XDR2 out of the box but use gddr5....... I can think of at least one console which uses XDR1 right now, who are rumoured to be going to AMD for their next gpu....... I can think of another console which uses AMD and would benefit from XDR2's increased speed AND lower pinout(cheaper mobo's/less traces/better all around).

Even if XDR2 isn't in mass production now, it could be in a year and getting xdr2 working on the current gen mem controller could iron out any bugs for a future gen and tweaked console versions of the chip........ without end PC users actually seeing cards with XDR2 on this gen.

Realistically shader counts, bandwidth, nothing means anything without any context, GCN architecture shader count shouldn't be even slightly comparable to performance per shader from Vliw4/5. A circa 2k GCN card could be 33% faster than a Cayman, or 150% faster.

People are just saying march to be on the safe side "Just incease"
I just hope these new cards will be decent because I need something for the new computer I am building.
I am holding off on buying to many parts untill I know the new GPU's are out.

Always intended to get a second 6950, almost did last month for bf3. Talked myself into waiting, and now i'm waiting to see how well the 7000range handles eyefinity!
 
Do you think one of these for £300-350 will beat my crossfire 5870's?

I'm really looking for something to play at 2560x1440 at, the 1GB is clearly a huge limitation for me at the moment, but to beat crossfire 5870's in games where the 1GB isn't a problem we'd probably need a leap similar to the 4870 --> 5870 generation. The 6xxx series didn't seem like much of an update.

I think this will be a decent update, I will be careful not to take any leaps of faith on them though, as I would very much like to know how they perform.
since its new tech.
I don't know if it will beat your crossfire 5870's? though unless it falls into the high end category, would want to be top of the high end category.
