Compare any two graphics cards:
GeForce GTX 780 Ti vs Radeon HD 7990
IntroThe GeForce GTX 780 Ti makes use of a 28 nm design. nVidia has clocked the core frequency at 875 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this specific card. It features 2880 SPUs as well as 240 Texture Address Units and 48 ROPs.Compare those specifications to the Radeon HD 7990, which features a GPU core clock speed of 950 MHz, and 3072 MB of GDDR5 RAM set to run at 1500 MHz through a 384-bit bus. It also features 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7990, in theory, should be quite a bit faster than the GeForce GTX 780 Ti overall. (explain)
Texel RateThe Radeon HD 7990 is a bit (approximately 16%) better at AF than the GeForce GTX 780 Ti. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 7990 is a better choice, by a large margin. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.

Yeah but its a dual chip card soooo...
So, the 7990 still remaining the king of the video cards, even with dual chip
The Radion HD 7990 card makes a lot of noice compared to the Nvidia GTX 780 Ti
actully sold my HD 7990 to a friend because the noice was too much for me.
The 7990 at full load runs at 39 dba which is actually quieter that the 780ti reference card (by 2 dba). So I have no idea what Jan is talking about. The 780ti is a great card but it still won't beat the 7990 and the 7990 has recently dropped in price (in the UK at least) so it's really a compelling option.
I have water cooling in my tower and not the best air flow, so think that was the reason since there are no noise problem on my friend's pc.
It's okay to laugh at my stupidity/ignorance and i am not the best to such things, so just said what i self felt
its still a dual chip card to really make it fair you would have to sli two 780ti's to make it equal, although it would still be under performing than being a dual chip it would still crush the 7990
Nigga nigga nigga, you're 100% nigga
Nigga nigga nigga, im 200% nigga
the best card in the world is a HD 7990
i have a hd 7990 no regret
Nigga nigga nigga, im 300% nigga
Nigga nigga nigaa, im 400% nigga
Nigga nigga nigga, im 500% nigga
I don't care what these previous niggas had to say BUT THE 7990 IS THE BEST GPU OF ALL TIME!!!!1
The dual GPU argument is very overblown, I don't have any problems with my 7990 since 13.10 drivers. Frame pacing issues are sorted and most games have CF profiles available before launch. It destroys any game I throw at it and liquid cooling solves the heat and noise issue (not that it was that bad anyway).
You guys are nuts. How possible 7990 can be the best card if it really suck on power consumption, heat and price. 780Ti in SLI outperform it easily and the price will not be higher. AMD will never be able to get even close to NVIDA on graphics and Intel on processors they sucked!
@Volja
780ti in SLI max power consumption would be around 500W
and thats alot more than 7990 Power C.
It would outperform 7990 but only by 15% MAX at the cost of more power drain and 2x780ti cost around 400$ more than 7990.
When it comes to dualchip GPUs AMD is a fucking beast.

No it wouldnt be fair to comere it with 2x 780ti.
becouse an 7990 are tow full 7970.
And you cant compare an gtx 7970 with and gtx 780ti
Dem nvidia fanboys be mad!
All Radeon Graphics Cards are mainly known for their poor reliability to maintain steady and fixed greatly-presented graphics. In other words, if you were to install the Radeon 7990 in your in pc and launch a very powerful game like GTA V, compared to the GTX 780Ti or any other Nvidia card in general, the difference will be oblivious. Sound levels from the Radeon's fan(s), the heat conduction that it produces is twice as much than a GTX which would require you to spend even more moeny on possibly another case fan or a coolant fan or just setting the whole damn thing in front of an ac. Nvidia cards do make some noise when overclocked and ran during beefy games, but are certainly much more quiet than any Radeon card, and most definitely more reliable and lesa likely to fry when overclocked, leaving me to claim that financially and theorectically, the GTX 780Ti is a more compelling option than the Radeon 7990.
