Compare any two graphics cards:
GeForce GTX 660 Ti vs Radeon HD 7850
IntroThe GeForce GTX 660 Ti features a core clock speed of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 192-bit bus, and makes use of a 28 nm design. It is made up of 1344 SPUs, 112 Texture Address Units, and 24 ROPs.Compare that to the Radeon HD 7850, which makes use of a 28 nm design. AMD has clocked the core speed at 860 MHz. The GDDR5 memory is set to run at a frequency of 1200 MHz on this particular card. It features 1024 SPUs along with 64 TAUs and 32 ROPs.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 7850 should be 7% quicker than the GeForce GTX 660 Ti overall, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 660 Ti will be much (approximately 86%) better at AF than the Radeon HD 7850. (explain)
Pixel RateThe Radeon HD 7850 will be a lot (more or less 25%) better at full screen anti-aliasing than the GeForce GTX 660 Ti, and should be able to handle higher screen resolutions without losing too much performance. (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 max amount of information (in units of MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range 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 worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at 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 per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.

6 Responses to “GeForce GTX 660 Ti vs Radeon HD 7850”[...] Hey just wondering about the 660 Ti and whether or not it has been released it appears that it has but not exactly sure and in terms of price etc is it worth it instead of the 7850. I've had to post pone my build until after Christmas Uni has made me a bit poorer than I anticipated so by then hopefully the 7850 may have dropped in price as a counter towards the 660 Ti. I've also been using this website as a comparison for graphics cards would you say it's fairly accurate: GeForce GTX 660 Ti vs Radeon HD 7850 – Performance Comparison Benchmarks @ Hardware Compare [...]
Chupa ati! porra! vão tomar no cú , eu sei fazer uma picarreta!
Será que uma das duas roda meu tíbia?
teu cu fdp a hd 7850 só perdeu taxel rate e vai comparar os preços das 2 seu otário fanboióla da nvidia
the 7850 is better for me.. ....thus the memory bandwidth is 256bit..ive seen the 660ti and its not worth the money the 7850 can run as fast as the 660ti but and also worth every penny ...
a7850 e supeiror seu urro alha de novo o principal o o ultimo i ela ta na frente
