GTX280+ 55nm Shortly

I realise all of the above Greebo, but 10% isn't that much more, but it does begin increase the gap. I don't think it will 10% performance increase for the basic version though, which is what counts.

In your opinion.. do you reckon the card will be more like 5%-8%increase in speed for the base version? (as I think it will be unless they up the shaders by A LOT of MHz).

As for GDDR5> The bus bandwidth on the 280gtx is already very wide so I doubt that adding GDDR5 onto an already sufficient bandwidth pcb will actually help that much. (I could be wrong).

Not sure it will happen, but the best approach for AMD IMHO but be to keep the heatsink, change the fan to a quieter one, and sort the fan profiles out. They could then easily increase the base version of the card 4870 by 10% overclock to compete with the newly released GT200b (Is it 200b or 280b?). That would cost a hell of a lot less than sorting any die shrink or process change :)

I agree the gtx280 doesn't need more memory bandwidth, it needs faster core and shader speeds.

If same price as current gtx280's then 5-8% performance gain might be enough.

And as for ATI and the 4870 cards, they are bringing out their "super" ones which run at 800 core and have "potential" to go to 950Mhz but I can only see this happening with a voltage increase on the board. Most peoples standard 4870 max out at 800 core which is only a 50mhz increase from stock which is not a lot really.

However, if you can buy a 950/1200 4870 for cheap money it would give even the new gtx280 a run for the money performance wise.
 
There are some 4870's reaching 1100 (4400 effective) memory clocks now, but yeh the 800 core clocks aren't amazing but am sure that'll change with next rivatuner in mid august

Not so sure. I am under water but although I can do a run of vantage at 875, GRID won't stay stable above 800.

It certainly isn;t heat as card never goes over 40C.

Plus I can't get more then 1MHz higher than 1100 from the memory otherwise it artifacts.

Therefore the new super cards are either cherry picked or they have more voltage applied to the core and the memory.
 
Greebo, yeh sounds like the good clocks are prob down to cherry pickings and/or volt mods, if your "only" 840/4400 on water then perhaps 800/4200 maybe max on stock fan/heatsink for the masses

Interesting to see your results as my assumption that 900/4500 was attainable are maybe a tad optimistic ? I was using this in my decision to maybe get another card by early september
 
With very little voltage increase Gurusan (and others) are able to overclock the memory a fair bit. I have seen on here a 4870 with 4800effective on the ram.. and that was with just a water block on the cpu.. NOT the memory!!!! I think the core went upto about 890Mhzish.. I think it may have been 'The Asgard'

Bottom line is, current price is a MUCH better than crazy £500 ish at launch, but it could be a bit better, whilst I think your right Greebo... if it's the same price as current, then the GT280+ will justify it's price.

Looks like GTX280+ going to 2.5 ratio for core/shaders, unsure on memory

This implies 648 core and 1620 shaders up from GTX280's 602/1296, the max overclock I've seen on a GTX280 for shaders is 1460 so thats a 10% shader o/c over a pre-clocked GTX280 and 25% over a stock GTX280, with a 7% o/c on core, interesting to see how it clocks all round, imagine 55 process wont change memory clocks but if the + can o/c to 680/1700/2400 it should be good

Am reading through that thread now. ZOMG ITS NOT FAIR COMPARISON :mad:

Am interested in the card though, not a fan of the dual GPU model yet, nor the 4870X2's price tag (before someone says, well its cheaper than a 280 at launch, thats like saying punching an old man is better than punching an old woman!).

Any idea on a release?
 
I think Nvidia need to roll out the 280GX2 1st to get there speed crown back, then give it another few months and work on shrinking and dropping down prices sharply off its range.
 
I can't see a 280gx2 for a long time. I think nvidia are already selling the gtx280s near to a loss because of the 4870's. Looking at some benches of gtx280 sli and it does not seem to be much faster than the 4870x2 and sometimes loses they just would not be able to compete price wise. I think a 260gx2 might be a decent option but still they are selling really cheap also and don't think theres to much profit in them either.

I wouldn't count on Nvidia having made too much of a loss on the initial GTX series - they didn't sell that many and probably didn't produce too many either, knowing the 55nm shrink was only a short while away.

Well it was quoted as one of the reasons along with the 4870 sales for the very bad results they delivered today. Really seems like AMD will be able to pull a nice profit next time if they keep selling these lovely chips and can get Phenom more out there, lots of manufacturers already using Phenom chips.
