AMD/ATI RV770 - Radeon HD 4 Series Almost Ready
ATI is moving ahead the launch of its next-generation video processors, as reported by TG Daily. Despite its previous faliures in the graphics business and $8 million loss in the first quarter of this year - AMD's president and chief operating officer Dirk Meyer stated that the company will roll out a significant number of products in May ahead of schedule, including the new RV770 and mobile (M88) graphics parts. RV770 will launch as Radeon HD 4800 and will make its way into the FireStream stream processor and FireGL workstation cards. Both GDDR3 and GDDR5 memories ranging from 256MB to 1024MB will be supported by the chip, but ATI itself will only be offering GDDR5 cards with 256-bit memory controller. The Radeon HD 4850 version is set to come to market with an 800+ MHz core (the final clock has not been specified yet and will not be available until the final qualification is completed), while the 4870 will be the first mass-production GPU with a clock speed higher than 1GHz. The graphics processor itself will integrate more texture memory units (TMUs) - 32 in RV770 against 16 in R6xx. Expect mass availability of RV770 cards soon after their announcement in May.

Cheaper cores + more expensive cards = roughly equally priced cards.
FireGL August... retail 4870 some months later... ie. they are announcing now... to prop up the share price... but launch is still Q3 into retail channels.
"RV770 will launch as Radeon 4800 and will make its way into the FireStream stream processor and FireGL workstation cards." should suggest otherwise... likewise with this line "We hear the company has struck gold with the RV770 and will be bring the chip to market earlier than expected."
The new desktop cards from what I remember were always slated for June/July.. lately there's been rumors about it being ready ahead of time and this just backs that up further so you suggesting that it won't come out till even after August doesn't make much sense unless you're just trying to stir up poop.
could have make use of all those 3xxx goin for sale
So if the performance is not that much greater than what Im getting, Ill just wait for them to go cheap like the 3870s are now :)
The trouble though with those kind of posts is that it makes it seem like nothing is good enough for you, nvidia's at 128 shaders, why should ati have to be at 1024?
the 4870 should have 480stream processors through 96shaders. making the x2 a beast with 960sp's and 192 shaders. combine that with 32tmu's per core and gddr5 and it starts to look really nice. while again that is on paper we can only hope that this thing actually delivers.
Of course I wouldn't mind if ati increased the rop's to 32 and reduced the amount of simple shaders while increasing the amount of complex (something like a 4x4 setup would be sweet) I think the 4870 will be a decent performer.
(Note: AMD has more or less admitted that the 512bit memory interface on the 29xx lineup was really there to cover up for poor filtering/AA performance and architectural flaws than anything else.)
It seems everyone is "budgeting" their GPU's nowadays. Nvidia with cut-down G92 and its various offspring and ATI with their "tweaked" and "cooler" 38xx lineup. Both of which are nearly identical to their predecessors aside from being manufactured on smaller fabrication technology which allowed for somewhat higher core clocks.
I think the days of monster GPU's are long gone. Massive performance jumps and architectural improvements from one generation to another seem to be a thing of the past. Anyone who's expecting a monster GPU from AMD this summer, and then a monster GPU from nVidia in retaliation, is fooling themselves. AMD simply can't afford to make one and nVidia simply has no reason to make one if their competition can't do it to begin with.
Anytime a GPU developer pushes the the power-draw of their latest generation GPU as the foremost feature, you know for certain that performance has either suffered or hasn't improved much or at all vs. the previous generation.
hey addsub ROPs are outdated everyone uses shader units now
Some of the other things you mention are also sounding a little off. While AMD is not in the green yet the last article I read on their profit situation pointed out that while it dropped from Q4 2007 it is up vs. where they were this time last year. Given the effects of holiday spending and the release of the 3000 series it probably should be expected for it to drop from Q4 last year by virtue of Q4 just being a particulary strong quarter.. the increase from this quarter last year should probably suggest that things are picking up for them (or if you prefer something that retains more pessimism, they're only in the shit up to the knees this year where they might have been up to their waists last year). Likewise, last I read they actually gained marketshare (from an article on VR-zone a couple of weeks back) with their 3000 series.
Asides, though, I'm a little concerned by AMD saying they're going to be releasing stuff ahead of schedule - that could be either good or bad, depending on how "ready" the product is.
Little bummed about the 256-bit MEM BUS, but, IMO, GDDR5 partnered with a 1GHz GPU? I think she'll still be game. Although, 256b might be pushing it if a card gets packed with 1GB of GDDR5. I think that 1GB claim will prob be for the GDDR3 - on that note, why 3?! Why not use 4 instead? If a whole series was stouting GDDR4 and GDDR5, they'd be ahead of the curve over nVidia on a technological level.
GDDR4 must still be uber expensive, ATM.
2./ You cant really compare the unaudited Q1 vs Q1 figures for 2007 and 2008. In both situations there is a significant loss. In 2007 there were significant costs associated with the Ati aquisition. To say profit is improved and everything is OK is falling into the apples vs. oranges trap. There are so many significant adjustments to the window-dressed accounts. Only last week the AMD board had a showdown with investment analysts and they were NOT convinced that the AMD board was delivering... (google for the transcript). AMD *must* do some +ve PR work at this time. If not, not only will the share price sink further... but there will be pressure to replace board members.
I'm NOT arguing about dates of which model gets released first, firegl or consumer. Thats not the issue. The point is the "release being brought forward"... " we are ready to release"... "revenues coming soon"... "promise"... is all *necessary* PR to keep the (investor)market happy.
