GTX 595 Power Consumption

I saw the GTX 590's power consumption (365w) and that is pretty high for a GPU. I know it is a dual GPU card, so a high TDP is to be expected. The hd6990 has a max TDP of 375w though, so a little higher, but normally outdoes the GTX 590 by a few FPS. The GTX 590 has dual eight-pin connector, as does the hd6990. I got to thinking, the GTX 595 will most likely have a higher TDP than the GTX 590 which I would think is around 410w. If you think about that, is it really worth the money you would dish out for it? (I would guess around $900) A hd6990 or GTX 590 would pay for themselves pretty quickly and cost less too without much a huge performance hit. Since the GTX 595 isn't out yet, I am not going to say it is not worth buying, but if my predictions are correct, I would get it.

about GTX595 there is still no official words about it. so it is hard to say....

let's hope it won't be a fail

What makes you think there will be a GTX 595?

I doubt they can make a 595. They're already limited by there being far too much power draw and far too little cooling. I mean our CPU coolers are 3 times bigger and draw 3 times less power lol.

only thing i know there were some rumor about it in EVGA forum. GTX590 from nvidia and GTX595 from EVGA. they speculate the card will be 2 GTX560 on a board but i think that 'GTX595' they were discussing are GTX460 2 win from EVGA. but even with that some people choose to believe EVGA will release 2 GTX560 on a board a.k.a. GTX595 on later date...

A pair of 560s would be slower than the 590 though, so calling it a "595" would be quite silly (and misleading).

Yeah, there were rumors of EVGA being the only brand to make the 595. I would think it would be two GTX 560s on a board because two GTX 460s would be blown away by AMDs card. By the way, does anyone know what two cards are on the GTX 590?

It's a pair of downclocked 580s.

A pair of 560s wouldn't be anywhere close.

Wow, the hd6990 is running off of two hd6950s, but can be switched to 6970s, and it beats the GTX 590 in most games. How is that possible? Maybe they scale better?

yeah I was referring to the minimums of crossfire vs sli not a single which like you said, is the same add a second card and the results are quite different imo, maybe not for the ultra high end crossfire and sli but just in general

People need to forget the GTX 595 moniker. That was the rumored name, almost a year ago, of the dual chip card we now know as GTX 590. EVGA further confused people by showing their dual chip card, which was then speculated to be the mythical 595, but as we now know is called the GTX 460 2 Win. There will not be a GTX 595, ever.

Ah. Well, I can't seem to find much data on that but I'll keep looking. I'd certainly like to see hard data on it - I know you've said previously that was your experience with it, but I like to keep things as empirical as possible.

Is the GTX 460 2 even real?

Hopefully, there will come a time when blanket statements about performance will no longer be made, because, as we all know, results vary depending on the game.

As far as the dual card scaling/minimum FPS goes, have fun with this page:
http://www.xbitlabs.com/articles/video/display/radeon-h...



And using the chart below, we get the following summary on dual card scaling:

1920x1600
79.3% for the 6970's in Crossfire
72% for the GTX 570's in SLI

2560x1600
81.9% for the 6970's in Crossfire
84% for the GTX 570's in SLI



And finally, anyone wondering about which games favor the 6970 vs. the GTX 570, here's one for you. Bars to the left of center favor the GTX 570. Bars to the right favor the 6970. In general, games either favor the GTX 570 by a lot, or the 6970 by a little:

First, the 6990 isn't a pair of 6950s. It's a pair of downclocked 6970s. It has all of the core turned on, unlike the 6950 which has some of it disabled. It's default clock is above a 6950 as well (but below a 6970).

As for how the 6990 keeps up? First, it isn't downclocked as much. The 6970 is slower than a 580, but the 6990 is running at 830MHz compared to 880 for the 6970, so it's down by 50 MHz. The GTX 590 on the other hand is all the way down at 607 MHz, compared to 772 for the 580 (so it's down a full 165 MHz, and from a lower baseline as well). The 6000 series scale a bit better than the 500s as well. This means that even though the 580 is pretty substantially faster than a 6970, the 6990 and 590 are pretty close.

Yeah, I know it is two hd6970s down-clocked, it is just kinda close to the hd6950. You can flip a switch on the side and turn it into a full hd6970 x2 card though.

Honestly, it's closer to the 6970, since it has the full core running (complete with all of the ROPs and shaders). It's the same reason why I'd say the 590 is closer to a pair of downclocked 580s than it is to a 570, even though the clocks of the 590 are well below even the 570's.

thanks great info here, it seems like the sli has higher minimums across the board, and in some places were it really counts (approaching that 30 fps mark) although this is the high end and I would think my 6870s in crossfire's minimum fps would fall a good deal below that of a 6970 crossfire, thus the problem that I encountered, (or at least one contributing factor)...

The bottom line is that if you are going for sli or crossfire, imo, it is best to go high end if you value your minimum fps...

at my res 1920X1080, scaling for sli and crossfire of the 6970 vs gtx 570 is not much difference what like 6% to the AMD cards? I'd take better minimums and drivers personally over the slightly better avg frames of 6970 crossfire

The other thing I hope you caught is that the 570's scale better at the higher resolution than they do at the lower resolution, therefore they are more prone to CPU bottlenecking than the 6970's.

Just a quick word, this is my last day on good ol' Tom's Forums for a while. I scored something like 50+ Best Answers this month, ~2-3 per day, but now it's time to take a break. The real world is demanding too much of my attention, and I find I'm talking about high-end gaming more than I am actually doing high-end gaming.

What?!?! Why would you leave?! Just kidding, I understand. I have spent a LOT of time on my computer too... :cry:  Well, I hope you have a good time in the 'real world'. (What you think is the real world is actually "Virtual World 2.1", the democrat party just wants us to think it is real) ;)

yes I did notice, thanks for spreading the good word and have fun taking a break from Toms, we probably all could use one :)
