Curious: 2X7990 or 2xTitan

Which would you prefer?

  • 2 X 7990 AMD

  • 2 X Titan SLI

  • Don't care, I am happy with my single card solution.

The AMD essentially would be Quad 7970's and of course power draw would favour the Titan. But in terms of user experience and eye candy to the max which would you prefer?

If I wanted to run two 7990's in my desktop, I would need to pull an additional 20A circuit into my office!

On a serious note, until AMD can get there multi-GPU drivers in order the Titans are the way to go.
 
2 x Titan is a much better option as SLI is more robust. also its better to have the least number of GPUs as scaling beyond two GPUs falls rapidly.

Stole my thoughts as I was typing them.
Also CUDA > OpenCL in compatibility/adoption.
 
With the current unofficial 7990 and drivers I'd go Titan. Once it's officially released I'd like to retake the poll with the real 7990 data.

Yea the idea was to compare againsts the official 7990s. Having come from a 4870 X2 I am looking forward to this.

The 4870x2 was a very competent card and performed admirably. The 6990 however had massive thermal issues, something that is very common with AMD cards, hence my current cards are underwater.
 
Well, there's probably no way to know what the driver rewrite and crossfire tuning will do at 7990 release. As of today I'd go Titanx2.
 
There are no 7990 cards, so how should I be able to compare? I just ordered a Titan, because all dual tahiti cards are custom cards and have problems with CF support in some titles even when regular CF works.
ps. when official 7990 launches? is msrp known? maybe I should put that titan order on hold.
 
1x7990 + 1x7970 would probably be better than 2x7990 anyway from a value/power perspective, not that you get much value from either.
4 card scaling is generally pretty bad I believe.

My thought currently.

I would tend to believe the official 7990 wont be released without proper driver support. Pointless otherwise.
 
Scaling with 2 7990s isn't likely to be that good. More often that not Titan SLI would be faster. Also, Titan SLI will be smoother and with fewer hassles. Anything more than Titan SLI is anyway not needed unless you want to go Eyefinity or UHD Eyefinity.
 
More than likely I may end up getting one 7990 and x fire it with one of my cards.

I think Tri does work nicely compare to Quad fire.
 
GTX Titan SLI for sure.

There is like 10% difference between a GTX Titan and GTX 690. Meaning it will most likely be the same between Titan and 7990 too.

4 GPUs scale much worse than 2 GPUs which you can see from THIS link. 2xGTX Titan beat 2x690 and the same can be applied to 2x7990.

Then you have the latency issues with more than 1 AMD GPU setup.

All in all, better performance, more smooth gameplay, less power consumption, very little stuttering = GTX Titan SLI

AMD driver team is working very hard to fix CF issues for official 7990 launch. Gotta keep that in mind.

Very true, they can't launch a card that is going to get chewed up and spit our by so many tech review sites (Now that a lot of them are killing them on their runt frames and frame times). They want to be on top again for the fastest graphic card.

Not really. Although in this case I support Titan sli but your logic is wrong
690 is a bit faster than 670 sli.
7970ghz stock is about 20-30% faster than 670 stock.
7990 is at least as fast as 7970ghz cf.
So 7990 is probably going to be 20-35% faster than a 690.
And a 690 is usually about 20-30% faster than a Titan.

In addition 690 is slower than 2 X 680.
 
All I know is, I just ran my 7970 Asus Top 3GB.. on Half Life 2, and I am getting between 250 and 300 FPS.. consistently~! Now that's gaming. HAHAHA, before I got a GTX295 I had 2xGTX260s in SLI.. it was cool but not realy.. the 295 still smoked em.. but this was a long time ago kiddies..

Did you even read my link? It clearly shows that Titan SLI is 5% faster on 1200p, 3% slower on 1600p and 8% faster on multi screen, than 2X690.

Second, what planet do you live on? TechPowerUp have already tested the 7990 Devil. Its 7% SLOWER than GTX 690. Clock speed is 1000Mhz and GDDR5 is running at 1375MHz.
LOL @ you thinking the AMD 7990 will run at 1400MHz to beat the 690 with your dream figure. Its not remotely possible.

Third, the reason why AMD even want to make the 7990 is because they aim to fight against the Titan with lower price.

Seriously dude. Better start reading some reviews and have your facts straight before telling people that their logic is flawed

Titan SLI for sure. As others have mentioned, two cards scale much better than four and the power consumption would be much better too.

Going from a strictly price/performance ratio, 3x7950 would be comparable performance wise and much cheaper ($2000 vs $900). Or even 7990 + 7970 like Lonyo mentioned ($2000 vs $1200).
