That's interesting because GTX 280 debuted at $649 and only with 4870 its price still came down to $499. You are lucky ATI isn't pulling NV pricing in the first place.

does everybody keep forgetting that the 5870 is only HALF of ATIs flagship card so if anything $399 is quite pricey. Nvidias prices were ridiculous but ATI is priced even higher since their flagship will have to be well more than $649. these are next gen parts so they are supposed to be faster and better for about the same price range as last gen. and please dont say the new cards are faster than gtx2xx because that is only a temporary comparison and is certainly not their direct competition.

you are mostly correct since for the forseeable future most of the 5xxx series will have to compete against g92 parts. however, a few of the high end nvidia cards are actually based upon the gt200 core so we should use them for some comparisons, no? If nvidia had benchmarks, rumors, leaks, something, ANYTHING then I guess you could even try to compare 5xxx to gt300, but as we have no info at all to go on we're just going to have to limp along comparing amd's current lineup to nvidia's current lineup.

No, wait, I think that we should tell everybody who has a video card go bad, or who needs a new system, or who just wants to play with dx11 and win7 that he should wait around until gt300 comes out. How long should he wait? nobody knows, probably not even jen hsun huang. Tell you what, we'll just tell everyone to wait "a month or two", then check back with us and we'll see if any rumors have finally surfaced.

With SFR/ST exactly the same thing applies, at least until the pixel processing stage anyway.

Now, at the pixel stage I?m not sure how the frame buffer works with these schemes. It could still be 11520x4800 but simply have zeros in the areas that are flagged as ?don?t render? for that particular GPU.

I guess memory can become an issue here. Would you use 128MB card for 1920x1200? Because that's what it would be like when there are 24 monitors and we assume that they used 2GB cards.

Yes, it could be an issue but SFR/ST doesn?t necessarily solve that.

4 lines or super tiling.

I don?t think you understood the context of my question. If you?re not splitting workload based on monitors then you still need a 11520x4800 resolution, and all cards have to replicate the same frame, unlike AFR where they have different frames.

This is because SFR/ST splits the scene at the pixel level and there?s no way of knowing where those boundaries are until the vertex/geometry stage has been resolved. So simply going SFR/ST doesn?t necessarily guarantee any kind of VRAM saving.

That and vertex/geometry processing doesn?t scale like it does with AFR since all of the cards in the system have to replicate the same workload at those pipeline stages.

Again I?m not saying Eyeinfinity is using one scheme or another, I?m simply saying you can?t automatically infer AFR has been removed, at least not until have evidence that states this.

We know the 5870 has the same core clock but double the execution units and a bumped memory clock over a 4890.

But we don?t yet have any details about the 5890, AFAIK.

Well there are rumors saying the 40nm cypress core clocks near the same as the 55nm HD4890: to around 950-1050 stock volts/air cooled. Also the memory being used is 1gbit 0.4ns Samsung 5ghz chips clocked at only 4800mhz at ~1.5v, so there is some room there too. I don't know if they're making a 5890 with the cypress core, or later using a revised core, but I'm guess 1000mhz or greater should be easy.

I don't know if this has been posted here, but hell it's a frickin sexy bad ass videocard.
5870

It looks like a hotrod. :laugh:
Too bad it will cost 400 $, which in my country translates into 400 euros, which is too much for me. Come on Nvidia, give us some magic, faster.

I wouldn't be shocked if AMD holds that part in their back pocket and pulls it out depending on how strong the GT300 is, assuming the GT300 does come out some time after AMD's 58x0 parts.

the 4890 was a result of TSMC's 55GT process, which allowed them higher clocks with a still larger die. if i'm not mistaken, everything "high performance" about that fab process has been incorporated into TSMC's "general purpose" 40nm process. So there will have to be some new ingenuity involved on top of that if there is ever to exist a 40GT process. HKMG is coming at 28 or 32, and I'm sure that will be a breath of fresh air for the largest/most ambitious chips on earth, but I can't say what's in store for the meantime. this still leads one to believe that the 4890 was somewhat extemporaneous, or that its design had been sitting on the shelf awaiting TSMC's 55GT intro.

It's a solid looking bit of kit if anything.

So... how loud is the stock cooler of the HD5870? Is there any information on that available? Compared to a HD4870 stock for example.

I'm not gonna trust bars with no numbers, it'll end up looking like a Tweaktown review where 2 points difference in 3DMark looks as if one card is 50% slower than the other.

yeah but the testing conditions may not have been the same. no information at all is given, but to be honest i think we're all a little more impressed than we thought we'd be. still not buying one though. meh.

That info confirms the existence of the 5870 X2 and also shows a 5870 is shorter than a 4870 X2. The 5870 is also 63% faster than a 4870 in HAWX, which is a great start.
