That's correct. It looks great RV870 launches in Q3 instead of Q4.

cant wait for technology cant we.

Well, if rv790 does not bring any significant performance increase, i hope rv870 comes out sooner than later.

well, first of all - it made me angry to see this "new information" giving exactly no information at all.. :/
Hold your horses next time, Przemyslaw, will you?

It's just a supposedly new (release) DATE, not information about the GPU.
Anyway - I hope it's not true. The sooner it comes the bigger the chance of poor performance. And what about the rumours saying that 40nm process is far from being 100% developed and ready - the rumours like:
- no power requirement improvements due to massive leakage (and hello - it is almost the only way to speed the GPU up)
- TSMC is using cheaper technology than it should in 55/40nm production lines ---> smaller progress in GPU speed.

It's good that it's only rumour, but you never know
I personally doubt that we will see any good 40nm parts fullfilling our expectations in 2009. But maybe real successors of those chips wil show up faster than anyone expected i.e 1 year from now on.

What hell are the specs of the RV870 anyway? O_O

Looks bad for Nvidia now when their next performance chips are those 55nm GT210-gpus..which are coming Q4

ATI's RV740 (first and currently only 40-nm GPU) doesn't look too bad from a TDP standpoint. It has 826 million transistors on a 136mm² die, and at 650MHz core with 1GB of 1.00GHz (4.00GHz effective) GDDR5 memory it only consumes 44-Watts. The die size is really impressive when you compare it to the RV770, which has 956 million transistors on a 256mm² die.

It's not accurate to judge the whole process (40nm) just by the first chips (they will usually get better in time), of course.

But I didn't read any test regarding the power consumtion of RV740 and I'd like to see a link to the site from which you got that 44 Watts.
I saw just a few prototype photos, that had a PCI-E power connector saying "more than 75Watt" (cause that's the PCI-E slot specification).

Let's wait for some reviews. I hope you're right, and 44W would be awesome.

Well, the Mobility Radeon HD 4860 has a TDP of 44-Watts, and that actually refers to the TDP of the whole card add-in package (GPU, memory chips, etc.). The Mobility Radeon HD 4860 and 4830 use the same RV740 core that will be launched for desktops in a little while, although obviously there are specially picked speed/voltage-binned parts.

Quick update: there is an actual retail listing for the Radeon HD 4750 card, and it claims to have a TDP of 78-Watts, making the 6-pin PCI-E connector just barely required. I believe the actual model name is wrong though; this should be the Radeon HD 4770, since it has a core clockspeed of 650MHz and 800MHz (3200MHz effective) GDDR5 memory. The Radeon HD 4750 will have a lower core clockspeed (probably 575MHz, matching the now-discontinued Radeon HD 4830) and use GDDR3 memory.
