GTX 780 TI SLI vs GTX 790

[Hardware Fanatic]

So I am thinking of purchasing two 780 Ti cards, however reading up it seems the 790 is expected this month. Now the 780 Ti cards I have in mind are the Zotac AMP editions and they will set me back £1068.30. The 790 is expected to retail for at least £850+, £850 probably being optimistic.

How much of a performance, overclocking and power consumption difference exists between AMPed SLI 780 Ti cards and the reported specs of the 790? And is this difference worth the price gap?

The 790 is two 780s put together rather then two 780Ti's. A little less power on one PBC.

I'd go for the Ti's

Thanks for your opinion Mciahel, anyone else want to share?

Generally, you would go for the dual GPU on a single card option because you are tight on space or you have some other configuration issues. Otherwise the two card option is better for the improved cooling spread out over a larger area. Heat management is key with Turbo Boost 2.0, so ultimately the dual card option will be faster if all else is equal.

In this case, however, the GTX 790 is rumored to be not quite a full dual GTX 780 Ti chip. It'll be slower regardless of the thermals.

Better wait because two GPUs on one card uses hardware SLI which is much better than software SLI

Actually they both use hardware SLi but the dual GPU card card would be slower due to the heat constraints.

the GTX690 use an on board SLI chip which is not found on and motherboard so the card is treated by the system as one GPU not dual GPUs

No, it is still seen as two GPU's.

the PLX chip is ude to manage SLI

Yes, it takes the place of the SLi bridge that is used to connect two cards together.

the SLI bridge connects but doesn't manage SLI

A dual GPU card still requires software to operate as a dual GPU card and it is the software that manages SLI and that software is the graphic card driver.

As said, SLI, whether on a single card or on two cards share all the same issues. The only meaningful difference is the bridge. You still have SLI enabled in the drivers, and games that have issues with SLI, still have issues with SLI on a single card.

Thanks guys, I reckon I'll be going for the 780Ti SLI then!

I hope you have a killer PC with a higher resolution monitor. My single GTX 780 Ti is nailing everything I throw at it. Funny, but I was playing Fallout: New Vegas and it wouldn't even go into full 3D clock mode while putting out 110+ FPS with every AA setting turned up to maximum.

Is the GTX 790 even due out anytime soon, or is it just rumors?

Good choice :^)

I have a 3D Monitor so would like to run all games at 120fps in 2D and 60fps in 3D. A single GTX 780 Ti doesn't cut it.

Reading online apparently it's been leaked that the 790 is due end of this month or next month.

the SLI bridge connects but doesn't manage SLI

geez talk about arguing misinformation to the death

 

[Shaureh Khan]

i know its off topic but if u take gtx 780 ti hof sli it would be the best way possible

I suggest you wait until the 790 has been released with all the specs since most specs are rumored however if it's anything like the 680 and 690 then definitely go with 2x GTX 780TI because with the 680...if you had 2 680's you could beat a 690.
