Is dual GPU the future? - Page 3

post #21 of 37
Whilst I love my crossfired cards I'd say that they probably aren't the future.
They consume too much power for the average PC user, require too much work on the user end to operate at optimum capacity and above all they have micro-stuttering.
First thing they need to sort out with dual gpu cards though is the cooling, one fan just doesn't cut it for reference designs. They need to have a twin-frozr type design for reference cooling.
If they sort out the above then perhaps they might be the future.

My opinion is that dual-GPU configurations will never be more than a niche solution.

I'm actually completely ignorant on this point--do GPU's have multiple cores, similar to a CPU?
Or are they all single cores?

I'm talking about a single GPU.

I think GPU's are now where CPU's where 10-15 years ago and like for CPU's with dual sockets, crossfire and SLI will remain the "ultimate" performance option. What I think will happen is that at some point in the next 10 years we will start seeing dual gpu's on a single chip in a similar fashion that we got dual core CPU's.

they are more of a niche then anything. I prefer sli or crossfire over comparable dual gpu setups. They will stay around but don't expect to see mainstream dual gpu cards, like a gtx 650tix2.

The point at which more chips > more cores is when no one can afford your bazillion core chip, and so you sell them as many of what they can afford.

I agree with what you are saying, but to further the point, there is a finite number of cores that can physically be added in a given space. While part of the equation is if anyone can afford such elaborate chips, the other part of it is if it is even possible to make at this point in time. wink.gif

I picked up a second GTX 670 2GB a few months back for my first ever SLI setup.

I am loving mine. The performance from 2 GTX 670's is incredible and i have never witnessed the micro stutter people keep going on about.

The only issue is heat but i solved that with a custom made side panel with side intake.

I couldn't be without mine now. I only have 2 games that don't take advantage of SLI and they arn't heavy graphics card useage games anyway.

I'd say for future proofing and high FPS SLI / Crossfire is a must, especially with a 120hz monitor.

Sure if there was a single chip, single card with the same performance and price point i'd chose that then SLI that but there doesn't seem to be one apart from titan but thats £400 more than my GTX 670 SLI cost me.

You actually can't really compare CPU's to graphics cards because the latter has the luxury of being designed for a much more specific set of tasks, where as CPU's need to remain fairly flexible and dependent on all your other hardware.

This article clarified things a bit for me: http://blogs.arm.com/multimedia/442-multicore-or-multi-pipe-gpus-easy-steps-to-becoming-multi-frag-gasmic/

Right now dual GPU graphics cards (the concept of building SLI / crossfire capability into a single card) is something of a very high priced and almost unpractical solution for high-performance rigs. But is dual GPU going to become an affordable and typical setup for graphics cards in the future? If we continue to use SLI / crossfire into the future for our more demanding computing needs then can we rely architecture and efficiency advancements to keep the individuals cards (relatively) low power and cool?

What do you think?

Why sell one card, when you can sell 2 cards!

There will always be single gpu cards, I think we will see 3 or 4 gpu cards next.

I have been messing with sli/cf for yrs now, 7950gt's was my first. And they sit have not figure out all the bugs yet and that goes for both sides!
