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.

Didn't AMD originally supply an info-graphic (about a year ago, just prior to the release of their 7000 series cards) that the 7790 card was to have been their lowest-priced 7000 series card that still provided a 256-bit memory interface? Any explanation for the downgrade now, to a 128-bit interface?campcreekdude - Friday, March 22, 2013 - link
I thought the 7890 is supposed to be 256-bit.Oxford Guy - Tuesday, March 26, 2013 - link
The big problem is that it doesn't have enough VRAM. 1 GB is too little for 2013 cards. Pretty ridiculous for one priced at $150.vailr - Friday, March 22, 2013 - link
Info-graphic from a year ago that shows the 7790 with a 256-bit memory bus:http://wccftech.com/amd-radeon-hd7000-28nm-souther...

Nice catch!CeriseCogburn - Saturday, March 23, 2013 - link
Amd lies all the time then fails to deliver, so the fanboys give them a thousand breaks, another chance, some more time - " in the future what AMD I bought today will be great, it's "futureproof" " (even though it doesn't work correctly right now)...LOL - goodbye amd
So the beta driver, uhh perma beta driver must have crashed out in civ5 a lot.

im sorry but if you must insist on invalid staments you shouldnt be on this website because smarter people will correct you on YOUR fanboyness. First of all amd beats nvidia at every price point(check linus tech tips on his youtube video card chanell) and they have perfect drivers. working for 6 months on the same amd driver and no crashes. infact i tried a new crysis 3 driver and it didnt crash then either and that was a beta driver. and my radeon 7770 destroyed the nvidia gtx 650, which is at the same price point.medi01 - Sunday, March 24, 2013 - link
I hope you work for nVidia.Because writing such crap for free is hard to imagine.

How do you keep a straight face when accusing others of being fanboys? You're the biggest fanboy I've ever seen.Deo Domuique - Sunday, March 24, 2013 - link
AMD Peasants, that's what we are... First time in my over 15-years "career" on PC gaming I went with AMD and a 7950, and you can't even imagine how much I regret it.
