GeForce GTX Titan vs Radeon HD 7990
Intro
The GeForce GTX Titan comes with core clock speeds of 837 MHz on the GPU, and 1502 MHz on the 6144 MB of GDDR5 RAM. It features 2688 SPUs as well as 224 TAUs and 48 ROPs.Compare all that to the Radeon HD 7990, which features a clock speed 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 made up of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If 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 texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum 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
