Compare any two graphics cards:
Geforce GTX 780 vs Radeon HD 7990
IntroThe Geforce GTX 780 features a clock speed of 863 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 384-bit memory bus, and makes use of a 28 nm design. It is made up of 2304 SPUs, 192 TAUs, and 48 Raster Operation Units.Compare all that to the Radeon HD 7990, which features core clock speeds of 950 MHz on the GPU, and 1500 MHz on the 3072 MB of GDDR5 memory. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 7990 will be 100% faster than the Geforce GTX 780 in general, due to its higher bandwidth. (explain)
Texel RateThe Radeon HD 7990 should be much (approximately 47%) faster with regards to texture filtering than the Geforce GTX 780. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 7990 is a better choice, and very much so. (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 max amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, 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 the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.

The 7990 over in Australia is $120 cheaper than the GTX 780. I am getting the 7990 for only $678, What a great price considering it used to be $1199. I know that the 7990 is dual GPU and the GTX 780 is a single GPU, but man it is a great card for the price.
Seriously I just picked up this card for like 300bucks! What a steal! And my god the raw horsepower of this thing is unbeatable!
Immediately bought two cards GV-7970 Ghz Ed. totaling $ 250. In the Crossfire is even more powerful than the same monstrous brother 7990
