Compare any two graphics cards:
GeForce GTX 285 2GB vs GeForce GTX 660 Ti
IntroThe GeForce GTX 285 2GB comes with a GPU core clock speed of 648 MHz, and the 2048 MB of GDDR3 RAM runs at 1242 MHz through a 512-bit bus. It also is comprised of 240 Stream Processors, 80 TAUs, and 32 ROPs.
Compare all of that to the GeForce GTX 660 Ti, which features clock speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 RAM. It features 1344 SPUs as well as 112 Texture Address Units and 24 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 285 2GB should be 10% quicker than the GeForce GTX 660 Ti overall, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 660 Ti should be a lot (more or less 98%) more effective at AF than the GeForce GTX 285 2GB. (explain)
Pixel RateThe GeForce GTX 660 Ti should be just a bit (about 6%) better at AA than the GeForce GTX 285 2GB, and should be capable of handling 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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, 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 higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. 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 is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
