RV775XT and PRO have 840 SP?

[Helmore]

Nope DX11 does not fully work on any available card right now. Some of DX11's features can be used with current cards though.

I think we will be getting a refresh, but probably the refresh will be a little later and will be made on TSMC's 40 nm. process. Just my guess though, but I think it's pretty accurate.

Yeah, I am thinking this aswell.

Makes sense now, because a 40nm refresh wouldn't have made sense if the RV870 was coming out in 1H 09.

One question though: I thought that before the RV775 rumor came about, everyone was saying RV870 in Q2 2009?

Pretty much everyone was saying that, but where did it come from is the question. I can't remember any proper source for that date at the moment. The date could still be valid, nobody except ATI knows what they plan on doing next year. Pretty much the only certainty is RV740 which will be their first 40 nm. chip. It's not sure what kind of chip it is though, w0mbat seems to be hinting that the chip is something more than just a RV730 done on 40 nm. and that it will actually use GDDR5.

You might want to go back and read through the fourth page carefully, lot more information there than you might have realized.
My speculation for RV740 seems to be right on and reaffirms the rumors we heard of tapeouts a few months ago, RV870 in Sept/Oct, RV740 in July.

[Jor3lBR]

So can we expect 4870x2 o bellow $350 on January/09?

[ColonelCain]

Who knows. It really depends how much GTX295 beats it by. AMD will price the respective competitors of GTX285/295 aggressively to get a decent price/performance ratio. This will happen for a little bit, until ATI has a chance to respond with new products.

[LiquidReactor]

doubtfully. It will be a miracle that a gtx 280 regular price will be below $350 not counting in special deals or MIR much less a 4870x2 under $350.

I'm sorry, your speculation and current rumours are just like the "R700 = 2009" rumours (Kyle Benett's tutu D: )...


RV740 = 1Q 09, displaces 4830 and maybe 4850 with smaller chip that uses GDDR5.

RV870 = 2Q+ 09, new mofo.

R800 = 3-4Q 09, might be skipped if RV870 is not DX11 compliant (but most probably is)

[thebluemeanie1]

Would there be any chance that the die size and transistor reduction may have some truth if ATI removed the sideport?

Not really...

[Macadamia]

Err... RV740 is at ES Stage already. A11 is running fine, but retail should be using A12 to enhance power-saving functions.
If it was a July product, we will see something like RV770 progress this year- ES popping up at March or April.
This is more like a Feb/March launch IMO.

[gumballguy]

I cant believe you guys are discussing this.

READ THE PIC! "all 775 data is to confirmed"

As in, 'is to be confirmed'
As in, is pure speculation.

Now we're semi OT just making our own estimates about which chip will exist and when it will happen... time to lock the thread :p

[largon]

Here's my guess for "RV775" (= cherry picked RV770).
10 SIMDs
900 ALUs
40 TMUs

Yep.
90 ALUs per SIMD.
Cause that's what I see when I look at the die of RV770. There's nomore than 10 SIMDs but each of the ten SIMDs has infact 9, and not 8 clusters. No redundant TMU exists on RV770.

I was wondering how long it would take someone to look at the die shot...

It's also possible a respin removed UVD hardware and replaced with ALU clusters, but not likely.

"RV775XT" is the AMD equivalent of GTX260 216......TSMC's process has matured enough for such as show by nV already...

[w0mbat]

Can u post a high-res die-shot pls.

[cadaveca]

It's on wikimedia...has been for a few months now...

[w0mbat]

I can see the shaders, but i cant see where u two detect the 900sp.

[largon]

10 rows and 9 identical blocks in each. The "9th block" being the redundant part would be my guess.

[spursindonesia]

At this moment, i'm affraid ATI's too financially constrained to make an anticipating move regarding nVidia GT200b cards, and all that they can do is just competing through price adjustment -if nVidia plays hardball and agressive in holding/reclaiming their current/lost market share. It's a shame though, since i do believe the RV770 mArch is quite efficient (in terms of die size vs performance) and expandable, relatively compared to nVidia's competing product.

[w0mbat]

AMD has more than enough money cause they were bought by some sandpeople.

The sandpeople just took the fabs and didnt care about the rest.

[w0mbat]

Ok, could be.

@largon: Ur in the news: http://www.hardware-infos.com/news.php?news=2597

[Shintai]

But the 9th row got a different size and shape.

[w0mbat]

No, compare it to the 4th.

[Helmore]

No, compare it to the 4th.

Shintai is right, that ninth row is different and is not some form of extra shader unit. It probably has more to do with scheduling and stuff like that.

LOL at Hardware-infos, they really do post everything they see .
