GeForce GTX 660 Ti vs Radeon HD 7850
Intro
The GeForce GTX 660 Ti makes use of a 28 nm design. nVidia has set the core frequency at 915 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this particular model. It features 1344 SPUs as well as 112 TAUs and 24 Rasterization Operator Units.Compare those specs to the Radeon HD 7850, which features a core clock frequency of 860 MHz and a GDDR5 memory speed of 1200 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It is made up of 1024 SPUs, 64 TAUs, and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core 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 fill rate is also dependant 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.

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
