Place your bets, Red or Green

Probably lol, I don't care which is faster, as long as it's 400 or less I'm having it for crimbo :) mymoneys on ati this round as it's a new architecture and nvidias isn't, that's about it lol.
 
Does it really matter?

In real world gaming I mean?

I have owned both brands. Currently got a 5870, though am considering crossfiring when the need arises. Gaming wise, would it make a difference if I had gone the other way when I purchased?

The real answer, is no.
 
Fermi failed on performance 1st.

I'm reckoning £275 for the 6950 £350 for the 6970 £430+ for the gtx580.

performance wise i reckon the 6850 will be just about on par, maybe a little behind the gtx480 and the 6970 will be 10-15% faster than the gtx480 with the gtx 580 being 20-25% faster than the GTX480. so the 6870 i think will be somewhere around 5-10% slower than the gtx 580.

of course what would be really funny would be if the new cayman chips turn out to be huge, hot and in short supply (not that i can see that happening) so they are larger hotter and more power hungry and of course louder than the Nvidia cards.
now its not going to happen like that..... but it would be lovely to hear the way this forum on the whole would twist itself inside out to justify these things.

I think some people have missed the main issue on the power/performance problems nvidia have, and just focused on the 330 TDP and breaking of the 300 watt rules.

For me the problem is fermi has very disappointing raw performance. If the card was twice as fast you could forgive nvidia for huge power requirements, but sadly it turned only a little faster, and much more expensive than what ATI had six months earlier.

Looking at the 330watt~ TDP of the GTX480 it should be wiping the floor with the HD5970 just to be considered even, but it turned out pair HD5770's could beat it for a fraction of the overhead.

well there may be a bit of ATI bias talking here but:

I heard a rumour the full cayman will have 2400 shaders. Ignoring clock speeds/die improvements thats a 50% increase in performance over a 5870. The 580 has 512 shaders, or 15% more than the 480 (which in itself imo was about 10-15% faster than the 5870, so for the sake of my rubbish maths we'll call it 30-35% over the 5870). SO that leaves ~15% performance to make up with clockspeeds and die improvements. I suspect the 580 will be more improved per shader over the 480 than the 6970/5870, but i cant see it being 20%+ more efficient (once caymans shader improvements are factored in).

Power consumption/Heat im expecting to be roughly the same...

So if i haven't made myself clear, my moneys on ATI for this round (sorry if my reasoning sounds like a load of BS. It purely speculation from me atm)

I'm inclined to agree. Dispite Gibbo's comment regarding the 580 may suprise I think the 6970 will have 2400 shaders too, something like:

1050Hz Engine Clock
2GB GDDR5 Memory
6,000 MHz Memory Clock (GDDR5)
2,400 Stream Processors
160 Texture Units
256 Z/Stencil ROP Units
64 Color ROP Units

with the 6950 at about 775-800hz. So I say Red wins!
 
Until the greens can start producing smaller chips the reds will have them beat on price/performance every single time. One has to wonder how much longer Nvidia will continue in this way of producing video chips with little to no margin.
 
^^^
Profit at the low volume high end is irrelevant, as it's extremely unlikely you can turn a profit here unless your competition is nowhere to be seen, apparently GPU makers are happy just to break even here.
The real problem is their much smaller chips don't have competitive margins either, like GF104, GF106 & GF108.

These are small chips in terms of manufacturability yet simply they just don't perform as well as similar sized AMD chips, hence it's actually just an architecture/manufacturing issue, and the issue isn't to do with die size.

6970 has 860 mhz core

Seeing as the AMD strategy is multicore for the high end id assume that the 580 will be slightly faster than the 6970, but obviously the 580 will get obliterated by the 6990.

This got me thinking actually....

They did seem very much for multicore on the higher end for the X2 releases 3870/4870, but they dropped the names for the current Mutlicore card, and it seems to be postioned at a much higher price point

I expect they will always have a multicore card, but i can't help but think the focus may have quietly shifted towards better single core card performance for the high end, with the Multicore cards being repostioned in the very, very highend segment.

Prev X2 cards if my memory is not playing tricks seemed a fair bit cheaper than the current one, Once you got the crazy launch £££ out the way and prices settled, the 4870X2 was around £50 to £60 or so more than the 280GTX if i recall, and the single core AMD cards were not as fast as the single core Nvidia GPU's, hence why they got bundled into a Mutlicore setup to take on the 9800/8800/280GTX's etc

Now it seems the gap, between single card AMD/Nvidia GPU's is a lot smaller/comming down to nothing, and the multicore AMD card seems to be getting more expensive and moving further up the price range, along with more expensive faster single core cards
 
That's what happens when there's no competition in the top end :( main reason why I wenati last couple f generations is they were cheaper for the same performance at a price point, if cayman turns out to be a monster I have no doubt it will be priced accordingly :/ if it's nt reasonably affordable il have to go 6850's as no sli on this board. Wouldn't mind a pair of 470's at the price they're at now.
