Synthetics
As always we’ll also take a quick look at synthetic performance to get a better look at our video cards' underpinnings. 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, a mix of a ROP test and a bandwidth test to see if you have enough bandwidth to feed those ROPs.
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.
Finally we’ll take a quick look at tessellation performance with TessMark. We have everything turned up to maximum here, which means we're looking at roughly 11 million polygons per frame.

"pulling 7W more than the 7770, a hair more than the 5W difference in AMD’s TBP"That 5W is not at the wall though. Factoring in rounding PSU efficiencies, it's very possible that the cards are only drawing 5W more. :)
"The Sapphire card, despite being overclocked, draws 6W less than our reference 7790."
Seeing how the Sapphire runs cooler in Furmark, that might explain a Watt or two in reduced power draw, coupled with the efficiency of the PSU, it might explain three or four even. :)

"NVIDIA has for a long time set the bar on efficiency, but with the 7790 it looks like AMD will finally edge out NVIDIA."What is your definition of a long time? As far as efficiency standards, I consider AMD to be better for the end result when looking at the full definition and application of the word. See the spreadsheet I created here about 16 months ago to understand what I mean: http://forums.anandtech.com/showthread.php?t=21507...

You just called Ryan a "dummy", did you, without even checking the statement further down which reads:"For anyone looking to pick up a 7790 today, this is being launched ahead of actual product availability (likely to coincide with GDC 2013 next week). Cards will start showing up in the market on April 2nd, which is about a week and a half from now."
If YOU had read the article, blah blah dumb idiot blah blah. As you've not replied to anybody in particular, your mistargeted rants could be construed as being directed toward the staff themselves, so keep it up and you won't HAVE to worry about what AT is reviewing in future.
Bottom line - it's faster than the 650 Ti, it's looking to be more efficient than the 650 Ti, and oh look, both have 1GB of GDDR5 on a 128-bit memory interface, which you seem to have forgotten when you leapt down AMD's throat about the 7790, and when you went on your childish tirade about the 5770's 128-bit memory interface earlier.
As far as I recall, Ryan didn't mention anything about when Titan was available to buy, only that it had launched. Pretty much blows your theory of Ryan hating NVIDIA out of the water, doesn't it?
I'm not sure if I've said this before, and apologies to everybody else if I have, but I'm done with you, full stop. I can only hope everybody else here decides that not feeding the ignorance you perpetuate on every single AMD article would save them time they could be devoting to something far less boring instead.
To the staff - is there anything you can do to introduce an Ignore List? Thanks in advance for your response.

A note about threading - doesn't look to be stepping in consistently, so sometimes it's a little difficult to see whom replied to whom.CeriseCogburn - Sunday, March 24, 2013 - link
You got eveything wrong again, and you failed to read the article not I, and you failed to read my reply addressing half your idiotic non points, so you're the non reader, fool.Now I have to correct you multiple times. And you're a waste.
650TI overclocks and it's only faster in a few amd favor games which are here, of course.
Strike one for tardboy.
650Ti runs fine OC'd too, which it does well: " We pushed Gigabyte's GeForce GTX 650 as far as it'd go and achieved a maximum core overclock of 1125 MHz, with the GDDR5 memory operating at 1600. All it took was a 1.15 V GPU voltage. "

The 128 bit bus - REPAYMENT for you FOOLS SQUEALING prior, what's so hard to understand ?
Did you forget all your WHINING ?
Did you forget your backing up the FAILED theorists with the nVidia dual speed memory ?
ROFL
You're up to strike 4 already.
" Ryan didn't mention anything about when Titan was available to buy, only that it had launched. Pretty much blows your theory of Ryan hating NVIDIA out of the water, doesn't it?"
NO, so why would it be mentioned if he didn't want anyone to buy it ? Why mention it, that would key in to save for release date, right ?
Instead we get this gem first off in BOLD to start the article: " Who’s Titan For, Anyhow? "
Guess that just crushed your idiot backwards bullhockey forever.
For all you know Ryan mentioned release date anyway.
You're not "done with me", you get everything WRONG, so you'll be opening your big fat piehole forever, that's how people like you do it. Idiot amd fanboys, all the same.
Also a beggar child for extra "control", since you "can't be an adult and control yourself" - please give me an ignore button ! I'm a crybaby who can't handle it !
ROFL

One question does your 650Ti pays for itself? this amd will pay for itself via bitcoin. even with the asics. especially if you heat your home with electrical heat.nuff said

To Ryan and staffAs a long-time admirer of AnandTech, I always enjoy reading pretty much every article you post, and have immense respect for all your writers.
However, I am now utterly fed up with the direction the comment discussions have taken. The general pattern is they start out as debates and end up as pretty nasty personal attacks that have nothing to do with the articles. You may say 'don't read the comments', to which I reply that they used to be an extension of the articles themselves, and were always a source of valuable information.
It pains me to say this, but if you don't start removing the trolls I will no longer come to this site at all, and I would guess I am not alone in having this opinion.

I agree 100% and actually sent off a few emails to the staff earlier in the day. I urge others to do so as well so we can put this problem behind us.KnightRAF - Monday, March 25, 2013 - link
I agree the trolls are out of control and need some pruning back. They have massively lessened my enjoyment of the site the last couple of times I've visited.
