No-one knows what the X2 will be like and a shared memory pool has not been confirmed by anything/anyone. So it remains to be seen what 48x0 X2 will be like.

ATI 770 marketing site goes live, inq article..
Here it is: http://www.radeon-graphics.net/
It confirms the 1 TeraFLOP and as the inquirer said: that "933 must sting" for NVIDIA. As the GTX280 is supposed to reach 933 GigaFLOPs.
P.S. Those guys from the inquirer are sometimes to stupid to be true, check this: "The smaller brother, aka low-yield, salvage part, the GTX260 is basically the same chips with 192 SPs and 896M GDDR3. If you are maths-impaired, let me point out that this equates to 24 ROPs."
It should be 28 ROPs for the GTX260 and they are talking about others being math-impaired :p:.
the site's down already :(
And I pointed that out a long time ago (the maths impaired thing)

Now if 4850 CFX scales nearly as well, 4x 4850 will barely miss 3way GTX280 performance, obviously in vantage, while costing about half the price of TriSLI.
I really wish I could share the remaining slides, but I've been told not to. My source is worth too much to me to share these.
Maybe I can try and shed some light on things in another way. I guess that if my word isn't good enough, W1zzard's is. He said from an early point that there would be 160 shader clusters. RV670 has 64 shader cluster. Each RV670 shader cluster is 4+1 (5D). It makes little to no sense for AMD to change the cluster design to 2+1 (3D), which would then result in only 480 shaders. There has never been any talk about 96 clusters, other than speculations.
My Asian sources has claimed 800 SPs from the very start, but they are off a bit too often for me to believe them without doubt. Especially when western sources close to AMD report 480SPs. Later I find out that AMD has planted a number of rumors, including 480SPs to create a smoke curtain, and that it wanted to surprise both buyers and especially NVIDIA by launching a card with 800SPs.
GPU-Z is not proof of anything. It's just a database with information and if the database is outdated, the information displayed by the program will be wrong. Kudos to W1zzard for creating it though, it's a great tool. It's just not 100% reliable for cards that haven't been launched.
I've posted slides, Asian websites have posted different slides from AMD presentations that all show 800SPs, the only contradictory stories I see are the ones using GPU-Z as a source of information, which is just misleading.
EDIT:
Can anyone show me a slide with any information about the number of shaders beside the one I and the Asian sites have posted that say 800SPs?

@andreas
fcry64 posted this but no one commented, I guess people didn't like what they say
this shows it having 480 stream, but it could just be a mistake and there's no guarantee that's legit since there's no picture yet to confirm it (at least with the 2900xt I'm pretty sure they flaunted their "320" shaders)

Yup, I got X48 for the same reason! Previously had P35 which would suck for crossfire.
P45 is great for CPU overclocking, but only dual X8 lanes for crossfire ... not good for dual 4870X2s.
There is of course X58, which would require a new CPU as well, and is not out yet, and also likely require new RAM.
R700= 4870X2
RV770XT= 4870
RV770Pro= 4850
Come to think of it, I'm not sure what they will call the 4850X2...
hmmm...
since I have x48 now maybe its time to go back to AMD and get dual 4870x2 instead of one 280gtx.
can anyone comment on how crossfire has evolved? My last crossfire rig was two x1900xt. There were problems with that setup that sometimes created glitches in certain games or no increase in performance.
Is crossfire working better now? Will it work in all games or only for benching?
Is it buggy? Do you still need one of those external dongle things to attch the cards together?
if those benchs are real then HD4870 Vs HD4850 :

..
X1900... isn't that when you needed a "master" CF card? No, you don't need that anymore, nor do you need an external dongle. The cards are connected by a ribbon cable on top of them, like SLI is. CF performance scaling has greatly increased, as has game support.
I don't know how that site benched the cards when it can't even get the default clocks for the 4850 correct
Im hoping for these cards to do well, i just got myself a P45 and wouldnt mind doing crossfire for once, since most games run fine on my 9800GTX and if the 4870 beats it, then i should have no problem running all games at good frame rates.
For what reason? Need a better heating element (radiator) in your room? Better multi-monitor support? I have a feeling they won't be working along with any of these 48x0s in CFX....the performance difference between the 38x0 and 48x0 is just to big to do that.
I was waiting for this picture to make the initial post to look great.

Looks like PowerColor jumped the gun and sold the 4850 in Hong Kong:

15194 w/ QX9650 at 4GHz in 3dMark06 default
Not bad methinks
15k on 3dmark06 is not bad at all.
I would love to see how does hd4850 scales with some more mhz on memory and core :D.
15194 w/ QX9650 at 4GHz, isnt bad..
E8400 @ 4.0ghz and 9800gtx gets the same..
http://www.pix.sparky-s.ie/images/sl...4i0z_thumb.jpg
I get 13.4k with 8800gts and E2180 @ 3.30ghz
review
yeah hopefully with new drivers its become better the WIC one is pretty impressive :D
If these posted earlier
http://img166.imageshack.us/img166/7209/it168sc0.th.jpg
are true, we may be unlikely to see improvements from the next gen cards in 3dmark06.
Score with Stock Intel Quad = 13k. Nice, but not amazing.
This does set up the 4870 to get 15k stock though, and 17k with a 4Ghz Intel Quad. (Coming HERRENDOUSLY close to the GTX 280 mark 0_o)
Perkam
3D Mark benches are nice to get at this stage, but totally pointless in the scheme of things..
Crysis, WIC, COD4, COH 1920x1200, Very High Quality are the benches needed to tell ous what these cards can do..
We might get these in the next few days, looks good so far for Ati
Card has arrived. Info will be in a thread tonight, So far I can say It is an excellent performer. I will be busy benching and posting results tonight. Stay tuned to XS for more information.
A little teaser 15k in 06 is easy (4600mhz yorkie). much more info coming.
full specs end the great SP debate:D
benching at 4600? :eek:
So you can crossfire a 2900 with a 3870? I found this chart:
http://game.amd.com/us-en/content/im...hart_Dec07.jpg
I'm pretty tired and maybe i'm misunderstanding it, but it seems to indicate you can't :confused:
I ran xfire in the early days of the x1900 and there was a bug here and there, but to be honest with you.....it was not as bad as some people claim. If ATI improved it which I hope they did, it will be a nice setup.
I also run on a X48 and Im waiting for results. I just cant seem to make myself run a Nvidia chipped mobo again. Good for benching, but lackluster for daily usage.
@ least @ 3dmark nothing honestly surprising @ stock (equivalent to my 8800GT), maybe with 750mhz core we should see what the HD4850 can do...
hopefully jimmyz won't pull an OBR on us
Nope I'm here:
forum is giving me problems.

I am going to get a full thread going once I get some benching done. I had a funeral today and had been swamped. got it installed and everything is good so far, let me get some more nubers and i'll post up.:up:
Thanks to FXvideocards.com they were great getting me this card so early. they will be selling them the 21st:up: http://fxvideocards.com/
more soon.. stay up. low run :up::rofl:
Ummm.... hey, am I the only one to notice that these numbers kind of suck, really badly? So, are you guys saying that a yorkfield @ 4.0-4.6GHz (an insane overclock unless you have unlocked multi) with a 4850 is only scoring ~15k in 3dmark06? That really, really sucks.
With my 2900Pro overclocked to 874/1000 and my Q9450 at 3.6GHz, I score 14.5k in 3dmark06. So if those results are real, then yes, that really sucks.
The overclock should be irrelevant. 06 is heavily CPU limited, and I have a 3.6GHz yorkfield, and they have a 4ghz yorkfield. That would be a pretty big balance tipper.
If the 4850 really has 800 SPs and 32 TMUs, then these results are extremely disappointing. Unless it basically doubles it's performance in crossfire, it's going to blow.
I can't blame people for doubting, but ask yourselves why until today I had no posts in this thread even though I am always a fan of the midrange ati cards. I will get more benches done soon, what speeds do you guys want for comparisions?
besides guy I'm naming sources, i got this card without an NDA. I am just a small town boy from Indiana, Out to bench anything I can get my hands on, the newer and rarer the better. gotta get back to testing. how about something like 4ghz?
Oh and this card clocks like crazy...lol I talked to W1zzard he confirmed it isn't reading right and the shader and other info is courtesy of a database that he will update to the real figures very soon hopefully.

Thanks again http://fxvideocards.com/
Yeah man please stop the 3DMark crap just run some games :p:
My Q6600 @ 3.2ghz and heavily OC'ed GTS got 15506
Both stock got 11877...
Q6600 @ 3.2ghz and GTS stock is 14259.
Yes, the CPU helps but so does OC'ing the card.
One Dutch webshop already has listed the HD4850 for 152 euro's
just for you stargazer I'm gonna run the crysis bench how does 1680 X1050 With high settings DX10 Cpu at 4GHZ and ram ( 4GB) at 5-5-5-15. card is still stock clocks and I can confirm at least in the Visiontek the stock is 625mhz and it maxxes under CCC at 700 (which it will do).
it does run quite hot 79c idle, but seems fine with it. I definitely need to spend a little time trying something to up the fan speed. the usual suspects are all in need of a tool lib update for this card.:shrug:
back in a while.:up:
do 'very high' also :up:
625...and maxes out at.... 700?:(
Don't be so pessimistic :p:, these cards can probably clock a lot better than just a measly 700 MHz.
thats perfectly normal like with all new ATi cards @ release date = almost none has software to OC beside the CCC
and the release date for the cards is only 25th ............
wait for a new version of Atitool or Rivatuner with HD4000 support
you can try AMDtool too !
regards
Where is HE ? :shrug:
extreme with a midrange single card? :rofl: this is a mainstream card. but that being said it scored X2808 (very pretty slideshow) with 4ghz Quad and card at stock clocks and default image quality.(balanced) no tweaks whatsoever to vista, set just like my daily use.GPU score BTW was 15676 , I will post screens when i get the thread up, gotta keep running tests, just wanted to keep you up to date.:up:
X2808 is a very good result.
What drivers are you using? Cat 8.6 beta?
Nice results
The extreme preset is what should always be used regardless of the card. It's not like it matters if it has low framerates; it's not like you're playing 3DMark. Using the extreme preset exclusively does the best job of factoring out the CPU, and gives a number you can always compare with other vantage scores. None of the confusion about one person benching one card with X, another with P, comparing scores, etc.. things would be a lot simpler if people just used extreme. 2800 is pretty good, seeing as there were rumors about the 4870 only scoring 2700-2800 on the extreme preset.
Cryyyyyyyssiiiiiiiiiiissss!!!!! :D
I thought that way too, but I've played through it twice already and I'm ready for another play through on highest difficulty. :)
Crysis is one of the few FPS's I've ever played more than once, because it is so open ended.
Anyway, X2800 is what we have heard from other sources, and that is pretty darn good IMO. It puts the HD 4850 above the 3870 X2 and if the 4870 ends up being 30% faster, then it would be around the speed of a 9800GX2.
