GF100 512sp benchmarks vs 480sp

As I thought, they've probably been speed binning GF100 chips that work with 512sp since they started production ¬_¬
Only hope here is that they not only have 512sp, but they've great clockers too! Then we might see something interesting :)
Either way, I kinda expect a huge premium on these things somehow... even if there isn't, I'm betting limited quantities, so a premium will end up on them anyway...

Same clocks, same pretty much everything, 6% more shaders, average 6% more performance, truly shocking that really couldn't have been predicted in any way at all :p

6% more performance for a TDP of around 360 watt going off my dirty calculations. That should give an average in game power consumption of around double a HD5870 :o and 70~ more than a HD5970 :o:eek::o

I get the feeling this card is not going to happen, although this is Nvidia and they still have one foot to go.

Is this actually an official nVidia card? For some reason I've been under the impression that it was a custom design from a board partner.
 
I just can't believe Nvidia would release this card, it's pointless. The 285 was worth it as it moved to a smaller die with numerous benefits even though it wasnt a lot faster.

The only thing I can think of is ATI SI will be slightly faster than a 480 so Nvidia release this to reclaim the single GPU crown but SI is still so far off.

Its August remember, SI is likely to hit around mid/late October so its only two months away, and this card seems like it would, well, lets be honest, they'll launch it a few days before to have minimal stock on shelves and try to make a little noise about lack of 6870 stock on shelves, for a week, or they'll launch it the day after to ruin the press coverage.

But frankly 480gtx + 6% performance, maybe 10% if they bump clocks up a bit more vs a tweaked and probably bigger SI chip, AMD should take the performance crown even so, maybe by a comftable margin.

But no one really knows where AMD are going with it, decrease yields and have a bigger chip, increase shaders by maybe 25%, bump clocks and add some efficiency improvements with the new non shader parts? Or same size, increased efficiency, maybe higher yields, only a little more performance but maybe at a decreased cost, who knows, we really don't at this point.
 
6% extra shaders, 6% extra performance 25% extra cost =Priceless :eek:

Didnt ATI say that the shaders on SI would be the same as the 5xxx series so it can only be performance and efficiency tweaks with maybe a clock speed bump but as drunkenmaster said we really dont know.

On 40nm? I don't think that's remotely likely unless they use GTX 460 cores, and then arguably, it wouldn't really warrant the name "GTX495".

hehe, Nvidia + naming inappropriately, I don't think they mind, don't they have at the mo 310-330 as 280 derivitive mobile parts, a 340gts as a 9800 derivitive, and a 350/360gts back on as the 280 derivitive mobile parts.

Frankly if 2x 460gtx is faster than a 480gtx, and it is, then calling it a 495gtx for a change, would actually be appropriate.

SI will be 2400 cores, 950Mhz core clock, 5ghz ram clock 384 bit :D

That is almost a certainty to not be the case, 2400 shaders alone, with the same current architecture with the same ratios as everything would be 1.5x bigger, so you'd be looking at a 3.2billion transistor core thats about GF100 size, IE unprofitable, low yields, and very high power, up the bus from 256 to 384bit would add another several hundred million transistors, power usage and lower yields a lot, you'd be looking at something 3.5million transistors + and the sole reason the GF100 sucked was it was too big to have high enough yields to be priced competitively. AMD's entire success over the last 3 years has been avoiding that one simple problem, too big = failure.

HIgher speed mem is almost a given, the rest is a balancing act, with very little space doubling everything is out of the question, giving a much bigger boost in one area is possible, will be very interesting to see the spec as it will pretty much tell us where they think/were most bottlenecked on the 5870.
