Compare any two graphics cards:
GeForce GTX 480 vs GeForce GTX 660
IntroThe GeForce GTX 480 makes use of a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR5 memory runs at a frequency of 924 MHz on this specific model. It features 480 SPUs as well as 60 TAUs and 48 ROPs.Compare those specifications to the GeForce GTX 660, which features GPU core speed of 980 MHz, and 2048 MB of GDDR5 RAM running at 1502 MHz through a 192-bit bus. It also is comprised of 960 Stream Processors, 80 Texture Address Units, and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 480 will be 23% quicker than the GeForce GTX 660 overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 660 should be a lot (approximately 87%) faster with regards to texture filtering than the GeForce GTX 480. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 480 is a better choice, by far. (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 information (counted in megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.

2 Responses to “GeForce GTX 480 vs GeForce GTX 660”[...] £178.39. Looks like a nice graphics card at not an unreasonable price. Comparing the two, using: HWCompare I am not sure my motherboard can cope & would support the GTX 660's Bus requirement: [...]
I have money for either one and I need help on deciding on which one I should buy. Other question is: what use is texel rate and how important it is?
