RV790 rumors?

Apparenty there are some rumblings about a refresh to AMD's RV770 to combat the upcoming 55nm GT206/200b parts that are "now shipping" from NVIDIA. The supposed chip will be redesigned to allow much higher clocks to allow the 10 SIMD clusters to come into "full swing" and will allow a single GPU RV790 board to be competitive with or outperform the Green Goblin's GTX 280.

This is news to me, and it would be great for this to actually come to fruition, but personally I think we won't see anything but price drops on the RV770 boards until RV870 rears its ugly head(s).

GTX 280 won't outperform the HD 4870 X2 with just a die shrink and a clock speed bump alone. Unless it got any other tweaks, HD 4870 X2 will still be the fastest single card.

While I think you're right about the 4870X2 being the fastest card overall post GT206/200b, there are games out there where crossfire simply doesn't work or scales poorly, which is where the 55nm GT200 will shine. However I was referring to a single RV790 board supposedly being equal to or better than a GT200/206, and have edited my post accordingly.

Vanilla Crysis and ... and ... and ... and ...Help me out here. Not scaling in what games but still beating its counterpart.

I doubt it will be anything special, die shrinks from TSMC aren't going to be ready till next year and AMD needs to milk R700 with R&D concentrated on R800 to get back to profit.
 
Considering AMD's financial status I think this "RV790" chip is just a rumor.

Course not, its taking a page out of Nvidia's book of 'milking the stupid' with refreshes. They just need enough to sustain the slight lead (at least their plan is to), then its all they need to carry them to the real battle next year: RV870 vs GT216/GT300. I will buy whatever comes out on top again.
 
I don't really see it muself, the high end is not what matters, as long as the x2 can claim top spot then that is what matters. The main place for selling cards is the 4850 and below so why do they need to beat their own high end?

It is kinda like the 8800gtx and the 8800ultra, not really any point.

Maybe the respin would be a just in case scenario. Also it wouldn't hurt if they could replace the 4850 with a 750mhz core, and the 4870 with 850mhz core. That would make the argument for a 9800gtx+ and gtx260 a lot harder.
 
Rumors come and go and serve to make people not go rushing into buying in the competition. Maybe it's just one of those

The refresh is said to only be to increase the frequiency by slight tweaks. Instead of 750 on the core, it is going to be 950 on the core.

I heard more along the lines of 850-900MHz....

These cards at stock are toasty enough as it is. They probably would need a board redesign for the extra power draw and added cooling in addition to a "slight" tweak.
 
I've seen only 950+ MHz. They will be using a new cooler most likely with that vapor chamber tech. My understanding is that they're redesigning the core (however slight) to handle higher clocks. It is obvious they would need more power to do that. It could also be a new revision that allows for less power draw, resulting in higher clocks. Similar to how we heard about that new RV670 coming out with higher clocks and smaller power draw.

If AMD is spinning this like they did with the SPs. I bet we're actually looking at a SP clock multi and that is where they're getting the boost from. Probably something they designed with the R800 to allow for a SP multi.
 
950 would be good. A stock 4870 barely requires the second 6-pin (under furmark load it should still be within the limits of a single connector) so current connectors should be able to provide the power for much higher clocks. I suspect it would need re-worked power circuitry and better VR for this, and certainly a bump in core voltage. I don't think anyone has taken a 4870 to 1GHz yet because the current cards don't respond well to volt-mods. I'm still looking for a card/driver combination that works properly - the 4870 would not run games under Vista and my 260 has more than a few issues (no 2D throttling, crashes for no reason every so often and no single driver set works with every program I use - even their own demos FFS).

It sounds like you need to reformat really bad.
 
if there is anything to these rumors then I am guessing that this is the ATI version of the ultra

I'm the first to admit that a format/re-install is the best way to cure a hosed system, but I've done it so many times while trying to get this rig sorted that I'm entirely fed up of doing so :(
I will probably post a thread on it when I've done some more investigations - don't want to de-rail someone elses.

Ahhh... A return to the XTX days? A 950MHz "RV770" would definately be a threat on price/performance, if nothing else, to the 55nm GT200 refresh.
 
Why can't nvidia just jam 2 280 cores into one card and call it the king?

Oh, I don't know, maybe it has something to do with a combined 470W TDP with two full blown GT200 cores, RAM, VRM circuitry? Not to mention the cost. It would easily be a $1K+ part (not that it would stop NV though).

I seriously we will see a dual GPU card until NVIDIA gets out 55nm parts and the thermals and power characteristics are radically better than the current 65nm silicon.

Oh, and +1 for thermonuclear meltdown. LOL
