NVIDIA GF100 & Friends speculation

between the 320 and 640 mb versions of the 8800gts it makes a huge difference the x1950xt had 512 mb so no that's not where the problem is when you look at the x1950xt and 640 version of the 8800gts, since the x1950xt is still 3 times faster in some situations. So AA isn't causing any memory or page flipping since we would see the problem on the x1950xt first.

The X1950XT used in the review you linked had 256mb. But it didn't use any AA, so it might perform much better in parts of the game where AA bottle-necked the game. This review is not even remotely comparable to 5870 vs. 480 in Heaven benchmark where they made an apple to apple comparison.
 
The chip is still bigger. 170mm2 bigger if its just 500mm though some seem to think now thats its over 550mm.

Also you still have another half a gig on the cards that ati doesn't have to deal with and a 320bit bus.

yeah but still the price advantage isn't as great as before, if nV prices according to performance, they too can drop prices down too, unless we are talking about no profits..... ATi will also get almost no profits. Going into a price war when they don't really need to is stupid, what happened with the 4870's did they gain marketshare? Was the 20% difference of launch price worth the gain in marketshare? Was reason for the price war justified at the end? Price wars are only effective if you gain enough sales to out weight the loss of initial profits

here then to make my point why does in some parts of the game the ati's card does better and in some parts nv's card do better, leave at that. Same damn settings! As I stated you missed the point there are parts of a game or demo that is going to be more favorable to one of the cards but the Heaven demo was built and optimized on ATI cards and where there is no tessellation in parts of the demo the card still looses, in some parts with tessellation it still close, but over all tessellation seems to give the geforce card a huge lead. If someone states those 30 secs are representative of all other games I think that is naive, if you want me to point blank about it.

Market share certainly matters if you are interested in gaining developer support for your software, or to counter your opponent's proprietary stuff.

The RV770's certainly gained a lot of points in favor of ATI amongst developers, and RV870 being out early for developers certainly helped them develop DX11 stuff and certainly won't hurt ATI's favor. This is in stark contrast to where ATI was in relation to Nvidia amongst relations pre-RV770

True but still ATi's dev rel program :LOL: lets not go there that's a different topic.

Never stated ATi's rv870 would hurt them in anyway, but development of Dx11 stuff has been slow, its nice we have 2 games that really use some nice effects but still going to have to wait a year so for more intensive shaders, just like Dx10, it takes time for adoption. Its possible a bit slower because of consoles.
 
yes please read my post just two above yours, also there are parts of the scenes where tessellation is off and the geforce has a nice lead anyways not 2 times but closer to 20%. (the video does go along with the graph, when and where the tessellation is turned on and off.) The first 40 secs and the last 20 secs there really is no tessellation....

Where they turn on and off tessellation in the graph is where you see the first two big spikes also when you see the 45fps, that's where you see where the geforce has the 2 times lead (100 sec's or so)
The very start of the demo is looking upwards over the dense grass to the windmill. You can clearly see the FRAPS counter indicating 60+ fps. This corresponds closely with the graph.

Now notice that both cards have the same framerate here. Bearing in mind that HTX480 is supposed to be way faster, why isn't it any faster at this "easy", as he describes it, part of the benchmark?

60fps is not actually "fast" for these cards, it indicates they're doing a hell of a lot of work, per frame.

Yes, I have seen your post later. Obviously I needed 3 minutes to write my one ;)

AFAIK, tesselation is never really off during the benchmark runs, it only affects more or less of the scene.
So the part of the video where tesselation is turned on and off at the dragon is especially interesting. With tesselation the GTX480 has 42/43 fps, with tesselation turned off it rises to 56fps. From my feeling, that 56 fps is definitely something a HD5870 is able to reach there at 1920x1080 without AA and AF (at least during the normal benchmark run it exceeds that framerate quite a bit at the dragon, but this is of course not exactly the exact same condition). Could someone with a HD5870 try to re-enact the view from the video (1:48 through 1:58) and check this?

IMO , running the benchmark without AA/AF is useless , even if done for showing architectural advantage , what matters is the final image quality with all the options activated , well .. for the average consumer anyway .

We both know that in games, ATI or Nvidia might have a lead on parts of the game. A simple explosion can change the curves even on a game thats benched real time. Reviewers like [H] makes several runs and average them, since there can be variations.

On canned, static benchmarks like heaven, there is less variation (drivers and system components might change the benchmarks, but the benchmark itself is static).

Those 30 seconds where there might be less tessellation, might indicate how the performance difference is in those cases. In my opinion, Heaven demo is probably no indication on how either card performs in real games. But, you cannot say that this is how the 480 performs vs. the 5870 when it comes to tessellation and at the same time dismiss that people say that the 30 seconds of little to no tessellation shows how it performs in that scenario.

Sorry shouldn't have said turned off, but when the camera gets farther away from the town near the end of the demo there is no tessellation going on, why there does the geforce have a 100% + lead, I think its a good demo to show the potential of the card in Dx11 environments but to try to say those lulls where the cards are close and say it will perform the same as the cards we have today, in Dx10 or less games, is a mistake at this point.

Its a good example of how well tessellation works on these cards, ATi has been using it for how many months now?

Oh yeah those 30 secs you might want to check what is going on before you talk, the video goes along with that graph. There are parts where tessellation is going on.
 
Sorry shouldn't have said turned off,
It doesn't matter what you should have said :LOL:, I'm talking about that part of the video where tesselation is turned on and off. It may allow to assess the performance drop for this obscenely tesselated case for both architectures.

So anyone out there dares to tell us how a HD5870 fares there (scene from video at 1:48 - 1:58) with tesselation on and off?
 
why should it worry you, its not like they have ever given out this much information before a card was launched before have they? We would have been lucky to just get a picture of the card a couple of weeks before launch in the past. I think nV is using it because ATi was and had beat their chest with it for the HD5xxx series when it came to features and performance of Dx11 and their cards.

Perhaps. Either that or Heaven is the only benchmark where the GTX 480's lead over the 5870 is significant enough to give NVIDIA something to brag about. We'll know soon enough.

about price if the gt300 is ~500mm, there is very little price advantage for ATi, its not like the rv770 and the gt200.

Assuming similar yields, which is assuming a whole ******* lot, but we've had this discussion already.

Hmm then why would they state time and time again, its going to be the fastest graphics card :), I would think its more then just Unigine where they are leading.
