Compare any two graphics cards:
GeForce GTX 660 Ti vs Radeon HD 7950 3GB
IntroThe GeForce GTX 660 Ti makes use of a 28 nm design. nVidia has set the core speed at 915 MHz. The GDDR5 RAM is set to run at a speed of 1500 MHz on this specific model. It features 1344 SPUs along with 112 Texture Address Units and 24 Rasterization Operator Units.Compare those specs to the Radeon HD 7950 3GB, which has GPU clock speed of 800 MHz, and 3072 MB of GDDR5 memory running at 1250 MHz through a 384-bit bus. It also features 1792 SPUs, 112 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7950 3GB should theoretically perform quite a bit faster than the GeForce GTX 660 Ti overall. (explain)
Texel RateThe GeForce GTX 660 Ti will be a bit (about 14%) better at AF than the Radeon HD 7950 3GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 7950 3GB is a better choice, though only just barely. (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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.

It will be worth 🙂
Well i hope so 😀

Anyone who reads this, I had zotac 660ti and just upgraded to sapphire 7950 3gb and not only does it get me a 10-15 fps boost in most games, it runs so much quieter and cooler. 660ti ran at 40-45 idle and 65-70 full load and very loud whiny noise from fan. 7950 idle 23-27 full load I've yet to see 60 and dead quiet
Oh ya. I also easily oced 7950 to 1050 while 660ti gave me artifacted with any oc
I have the Gigabyte version with the new bios. Gigabyte changed the core speed to 1000mhz, giving me: 32.00 GPixels, 112.00 GTexels and the bandwidth staying at 240.00 GB. Great card! even rivals the GTX 670 in some benches.
HD 7950 is way better only Nvidia games will run a li'll better on 660ti
Get an HD 7950 😀 🙂
Well..I AM ALSO WILLING TO GET HD 7950 BECAUSE IT GIVES MORE PERFORMANCE THAN 66O TI>>>
I am looking in to buying one of these 2 cards which will be better for gameing
Recently bought the Gigabyte 7950 and i got frequent crushes in the bundle games it came with and overall a very bad experience playing new appeared games. I understand is a driver problem that is fixed along the way BUT i didn't spend a lot of money to wait 1-2 months for AMD to get they stuff streight. So 660 ti for the win even if it's a small downgrade
check out neweggs deal with 4 games for the 7950, they are prety much the same price and according to this the 7950 is more powerful, is this realy a choice?
I Love my 7950. It is capable of running any game at 1080p high-maxed settings at high FPS. I will never regret my choice 😀
