Synthetics
As always we’ll also take a quick look at synthetic performance, though as a multi-GPU card using a known GPU, there shouldn't be any surprises here. These tests are mostly for comparing cards from within a manufacturer, as opposed to directly comparing AMD and NVIDIA cards. We’ll start with 3DMark Vantage’s Pixel Fill test.
There’s not much to say here. So long as the 7990 isn’t throttling, its ROP/memory performance is almost twice that of the 7970GE, reflecting the fact that the two cards’ clockspeeds are so close.
Moving on, we have our 3DMark Vantage texture fillrate test, which does for texels and texture mapping units what the previous test does for ROPs.
Texture fillrates are the same story as pixel fillrates: the 7990 is an extremely capable card.
Finally we’ll take a quick look at tessellation performance with TessMark.
And again, we're seeing almost perfect scaling from the 7970GE to the 7990 in our synthetic tests.

The card I don't understand the price/performance/name of is the Titan. Looking at these charts shouldn't Nvidia have called it the GTX780? Maybe I'm reading it wrong, but it doesn't look like much more than the standard generational change we normally get once a year from Nvidia/AMD, and follows on from 2012's 6xx series. Charging a grand for it seems a little offensive, in my opinion.prime2515103 - Wednesday, April 24, 2013 - link
"The GTX 690 is a 300W card and the 7990 is a 375W card. The GTX 690 consumes around 75W less power and puts off 75W less heat, full stop."If the 690 was consuming 75W less power and dissipating 75W less heat, it would be drawing 150W less in total. How did you calculate this?

Consumed power = dissipated heat. He's just pointing out that the increased power draw also equates to an increase of 75W of heat output.sulu1977 - Wednesday, April 24, 2013 - link
3 fans? Oh please, you can do better than that. For that price I want at least 9 whizzing fans because I simply love my quiet workroom to sound like a busy airport.tk11 - Wednesday, April 24, 2013 - link
More fans != more noise because more fans running at lower speeds make less noise than fewer fans running at higher speeds.chadwilson - Wednesday, April 24, 2013 - link
I know the whole mindset of put it out on release, but I really don't see a reason to read this article without FCAT information. Anyone who would be considering a purchase will be waiting until this data comes available with the latest drivers, so the entire article IMO is moot without it.JarredWalton - Wednesday, April 24, 2013 - link
Personally, if you're concerned about FCAT I think you'll want to wait about three months before buying any dual-GPU AMD setup. Maybe they'll surprise me and fix their drivers before then, but I'm betting on partial and flaky fixes for a little while longer.Beavermatic - Wednesday, April 24, 2013 - link
looks like Nvidia already responded with a Titan Ultra model today...http://www.cinemablend.com/games/Nvidia-Teases-GTX...
seeing how the 7990 is a dual-gpu card, and the Titan is a single GPU, I would hope the 7990 would beat it. You'd have been a lot wiser to compare it to Nvidia's dual GPU card, the 690 (which is already faster than the Titan to begin with).
The fact remains, the titan is like 15 to 20% slower than the 690 or 7990, and its single GPU. That's pretty damn impressive that the single-gpu titan can compete with the dual-gpu cards. Toss in another titan for SLI, and it slaughters both of those cards, lolololol. And not by a small amount, but by leaps and bounds.
Also, check the 7990 benchmarks, look at the microstutter and framerate averages. They are god awfully terrible as well as power consumption. What good is a card when it's rollercoastering framerates like mad? I know Nvidia's SLI has some issues as well, but they've really fined tuned it, but AMD's crossfire and multigpu cards are just horrendous, and shouldn't even be considered.

You can bet $2k in price would not equal double performance what $1k could buy.

I've got (2) Titan's in SLI and I didn't use a credit card, just sayn'
