Compare any two graphics cards:
GeForce GTX 660 Ti vs Radeon HD 7870
IntroThe GeForce GTX 660 Ti comes with core clock speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 RAM. It features 1344 SPUs along with 112 TAUs and 24 Rasterization Operator Units.Compare all of that to the Radeon HD 7870, which makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM runs at a speed of 1200 MHz on this specific model. It features 1280 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 7870 should be a small bit faster than the GeForce GTX 660 Ti in general. (explain)
Texel RateThe GeForce GTX 660 Ti will be a lot (approximately 28%) more effective at texture filtering than the Radeon HD 7870. (explain)
Pixel RateThe Radeon HD 7870 will be a lot (about 46%) more effective at AA than the GeForce GTX 660 Ti, and able to handle higher 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the 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 the graphics card can possibly write to its 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 clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.

NICE ATI....for 3D,Fast perform,and Gamer.
mang saya mau beli kompor 1 kintal
Ati beats nVidia alot....
in performance and price
