The Amazon specs are wrong. Both chips are the same deal, just different clocks.
I really recommend that you wait till the 4870X2, even though it's more expensive I'm really sure it's a heck of a card. :)

800SPs has already been confirmed due to TFlop numbers.
Now we wait for TMU confirmation.
Perkam
I'm betting its 40 TMUs, the diagram looked legit and keeps the same ratio the r600 did, unless if that diagram is fake and ati is planning on doing 8 arrays of 20 shaders to get 8*4=32, imo its 40
It seems R700 should be in available in 8 weeks, and there is no official name for it yet.

A guy on a another forum has been saying that the HD4870 is basically as fast as HD3870X2 in games that scale well in Crossfire and faster in games that dont scale that well like Crysis.
Results he gave on the two most demanding games.
QX6850 @ 3.0ghz
4gb ddr3 1066
Vista Ultimate 64
Crysis Very High 1920 x 1200
GTX 280 34.2 fps, HD4870 26.9 fps
Lost Planet 1920 x 1200 4 x AA
GTX 280 38.7fps, HD4870 29.86 fps
Scores are good imo, especially if Crossfire scales well..
Finally some facts, R770 has only 160 SP which are capable of 5 operations per cycle (that's where they concluded the 800 SP). 40 TMU's should bring enough balance for this configuration.
That is pretty much what I am begining to expect, RV770Pro = 480SP. RV770XT = 800SP
I am hoping that the HD4870 leans more towards 9800GX2 performance than 9800GTX as I am looking to upgrade from a 8800GTS
pop two of those in and then you will be faster than G280GTX (if software supports Crossfire).
If the HD480X2 is going to be any good it better have 2GB of RAM or a vast new improved multiGPU technology otherwise it is going to be the same old problems which can effect the GX2 and HD3870X2's due to 512MB of RAM percore?
John
You are very wrong.There is only one RV770 chip,and it has 800 Stream Processors or 160 shader processors with 5 stream pr. in them.
There is no 480 Sream proc. RV770 chip ,there never was.
To check this,you should look at Firestream 9250 thread in which AMD claims 1TF for basically Radeon 4850 with 1GB of frame buffer memory!One teraflop = 625Mhz x 2Flops x 800

hmm crossfire 4850 23fps in crysis very high 1920x1200 @ 4aa
Well with 3 GHz Phenom.
Thats quite... fast?
Way faster than GTX 280 and much cheaper :D
cpu really doesn't matter at that res, it may hinders the min fps, but it only marginaly influences the avarage fps.
im still searchign for a review with 1920x1200 @ 4AA but i only can find some with 2AA right now -> 280GTX 28fps 260GTX 23fps
ok for 280 gtx @4aa -> ~15-16fps

R700 isnt the same as R680.
Wow, these cards LOOK a whole lot nicer then the "COFFIN" that is the GTX2xx series
True, we dont know that, I know that ;)
Does that mean you are agreeing with w0mbat that the r700 uses some advanced technology over the r680 besides the new bridge chip or just agreeing (which many of us already know) that there are people here that are given cards to test out or have sources
It's not the same - don't put ratio in balance. For 320 (or should I say 64) - 16 is not enough - I own the card and I feel that from my own experience. For 800 (or should I say 160 SP) - 40 TMU might be enough. 320/800 - that's just marketing - 64/160 SP now that's something tangible since nobody can assure me that the present games or capable of working with 5 operations per cycle. It's a different kind of optimization which should be done in particular for ATi - and game dev. work on both grounds (both ATi and nVidia - even if it hat the nVidia logo on it). It's true that ATi can get more juice from their drivers but that happens rarely and they might optimize an older game (like we've seen among time).
Not really, in fact not at all. Get over it. All that matters is that the texture fill rate is now nearly triple of what the r600's was and that should be enough for most games at max details, except for crysis I don't see even the 4850 not bringing at least 30 fps at max details (in dx9 mode at least, we have no idea what dx10 does to the performance yet)

You doing a great job wOmbat :up:, keep us posted with more results, 48fps is quite close to what my 8800GTX can do at that settings. I think the 4850 looks like a winner for the price.
@ANP !!!: Ur 8800GTX does avg 48fps+ in WiC @1920x1200, all@max, 4xAA/16xAF? GTX 280 does avg 47fps w/ only 8xAA instead of 16x.
hah lol never
edit: you do realize thats a phenom? imagine those scores with yorkfield >4 ghz...
Again ,I ask you where is the proof that CF 4850 is worse for gaming than GTX 280??Link the proof in your reply and stop using unproven statements to support you view.
BTW 8800GTS SLI ,following your logic,is then faster than GTX280 while costing 2x less...And don't fool yourself with SLI 8800GTS being faster than 4850 CF,you're going to be very disappointed soon.
edit:also you are wrong about the prices of SLI 8800GTS and single 4850...
But I would say 9800gtx sli is pretty close to what hd4850 cf perform.
Yeah, but 9800GTX SLI is much more expensive.
I have been using 4 different cards on two computers over the last 2 years 2 x1900xt , 8800gtx, 9800gx2 ( sold it after 3 weeks, waste of money ) 2 x 9600gt and the single 8800gtx gave me the smoothest playing experience..
I would be getting the same mimimum frame rate of 15fps - 20 fps on my single 8800gtx, as I would on 9800gx2 @ 1920 x 1200, same would happen on 9600gt, only mimumum frame rates would be lower than 9600gt.
Now yee are talking about the amazing budget power of the 4850 and I've just my crossfire mobo for a sli one 6 months back....
Getting a bit pissed off at this stage with computing in general.
Nobody forced you to sell CF mobo and buy a SLI one..
And you still don't know how CF works with 4850 cards.So don't claim it performs worse in gaming until it's a proven fact.
so..

Radeons 4xxx aren't officially launched and you are using pre-release prices to compare them to a cards that just had price drops??Way to go.
Just wait 2 weeks and see how much will Radeons cost and compare it then.
Don't compare 1st gen CF with current ;)
And ati drivers are not optimized to the hd48xx as nvidia drivers are to 8800gt/s and 9800...
why are people using silly amounts of AA? realisticly you use the amount of aa to give you smooth frames like 40 or 50+.
that being said the cod4 crossfire score is really really impressive...
could someone run crysis @ max on 1680x1050? ;)
Are you sure?
http://www.newegg.com/Product/Produc...82E16814162009
$219 after MIR. A harbinger of things to come in the very near term. When the 4850 comes out that's what all the stock 9800GTXs will be selling at, or less.
Bye bye, nVidia :D
For me was the most interesting part the 4870 tests with GTX 280. In the Lost Planet, which we all know that is nvidia's speciality and there the logo that stays at the start of the game means well optimized drivers. To me all the other games instead of Crysis are the main target of comparison of the two cards.
P.S. All those lower prices of the cards are not available in all parts of the world, so we shall only compare the original prices, given from the producer.
Then you will wait until then and then will decide what to buy. It is simple. If you have changed your 9800GX2, which till now is the fastest card in the world, so the logic says that you don't have to buy GTX 280...
Crysis@1680x1050 DX10 very high 4xAA/16xAF is no problem w/ HD4850 CF.
U can play Crysis @30FPS really smooth (23FPS*1.3 = 30FPS).
It wont be constant, especially on crossfire, frames will be dropping well below 20fps to make a 30fps average.
Ok, but this is on a 3GHz Phenom, so w/ a 4GHz Yorkfield it should work.
y2kbos, please don't come here and make those kind of statements :(
It's sad to see someone saying that the GTX 280 is still a better card when it is slower than 4850 CF (which I don't believe actually) but your logic is screwed up. If 4850 CF > GTX 280 and 8800GT SLI > 4850 CF, then that means 8800GT SLI > GTX 280 :) And that's using YOUR logic ;)
@ Wombat, great results :up: But I believe we should be comparing 4850 CF ($199+$199 = $399) with GTX 260 ($399) and not GTX 280 ($650) because GTX performance is far from finalized from what I hear on the upcoming drivers.
Perkam
Now I know why ORBR was disappointed in the GT200 before NDA was lifted.
But I will wait for 4870X2 results before deciding between AMD or Nvidia
lol Ive been owned :D
They have me so confused
At least I didnt get rid of my perfectly good 8800gtx/8800gt like so many others, blinded by the hype, one good thing I suppose
We can't expect miracles from the drivers. 10% difference will be like a gift from the sky :). I really want to see more comparison tests between 4870 and GTX 280 or even 260, cause we know that the difference between the last two is around 15-20%.
Wow, if those CF numbers are legit, thats quite impressive and with a Phenom too. Can't wait to see how 2 overclocked 1GB 4870s do. I see DX9 tweaked very high at 1920x1200 with AA as being playable with a pair of those :up: As long as crossfire consistently scales, I'm going ATI this round.

Hot damn. Very nice :cool:
There were some men, who constantly claimed, that RV770 is the new R300 and GT200 the new NV30 for nvidia. Is that possible to happen at all?
Oh, it is. If the card that costs around 200$ beats nvidia's ultra mega hyper high end card, try to imagine what will do the x2 card...
It should be 10% faster and with better AA and AF capabilities and after selling your card and buying the new one you will have some money to celebrate the change :). But if that what we see 4850 does with games, that are not Crysis and Lost Planet, nvidia will have big problems.
