Compare any two graphics cards:
GeForce GTX Titan vs Radeon HD 7990
IntroThe GeForce GTX Titan has a core clock frequency of 837 MHz and a GDDR5 memory speed of 1502 MHz. It also features a 384-bit bus, and uses a 28 nm design. It is made up of 2688 SPUs, 224 TAUs, and 48 Raster Operation Units.Compare that to the Radeon HD 7990, which features a core clock frequency of 950 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 384-bit memory bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7990 should in theory be a lot faster than the GeForce GTX Titan in general. (explain)
Texel RateThe Radeon HD 7990 will be a lot (approximately 30%) more effective at anisotropic filtering than the GeForce GTX Titan. (explain)
Pixel RateThe Radeon HD 7990 will be a lot (more or less 51%) more effective at full screen anti-aliasing than the GeForce GTX Titan, and should be able to handle higher screen resolutions while still performing well. (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 (counted in MB per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.

13 Responses to “GeForce GTX Titan vs Radeon HD 7990”The Titan is a strong card on paper but with only one GPU core that is so strong it’s not as strong as a 7990. 7990 features 6GB GDDR5 memory the same as the Titan so I ask why and how can it be faster than the Titan? It’s very simple. The Titan has only one GPU running at 384 bit and its amazing how fast It can process information, but the 7990 has a Dual Core GPU each running at 384 bit’s of bandwidth splitting the work and easing the tension on the cores. If they brought out the Titan x2 I.E the Titan with Dual Core GPU each at 384bit’s it would be a mach for the 7990, but for now the 7990 is the superior card. Also a card to look at is the GTX 690!!!
so compara 7990 with 690 gtx that is a dual gpu too and close your mouth
Or compare a gtx Titan sli to the 7990. That's 2 gpus.
Compare price of 2x titan to 7990 😉
If you compare the Titan in sli you also have to compare the costs of both. 2 Titans will run you around 2 grand without tax and for that cost you can also get 2 7990s with a few hundred bucks left over, So make your pick.
Just wait for GTX 790 will be double titan, and you are comparing SINGLE graphic card to a dual - which is retarded ...
LOL 7990 is a way STRONGER then titan.
....and the price of 7990 is like half of titan.
So, why I have to pick titan? LOL. I'll pick 7990 of course XDD
I Wipe My Ass With Titans
yeah idiots wait for titan x2 and compare the price xD at least they will sell that card for 1.800 USD
In all logical terms the 7970 may have more power but it still comes down to drivers, nvidia drivers have always been more stable and draw out more and more performance with each consecutive update where as the drivers for AMD cards always play up and throw 40% of the cards performance out the window before its even doing anything. So when it comes right down practical application instead of theoretical performance, nvidia cards will always come out on top until good solid drivers come out for AMD
gtx titan is suck!!
7990 is essentially 2 7970s on one card ,so instead of looking at this compare the titan to two 7970s in crossfire and, honestly both "suck" as two 7970s cost less than the 7990 and the 780ti costs less than a titan and is equally, if not more, powerfull.
anyway thats real benchmarks
