Compare any two graphics cards:
GeForce GTX 460 1GB vs GeForce GTX 660 Ti
IntroThe GeForce GTX 460 1GB makes use of a 40 nm design. nVidia has clocked the core frequency at 675 MHz. The GDDR5 RAM runs at a speed of 900 MHz on this particular model. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.
Compare those specs to the GeForce GTX 660 Ti, which comes with core clock speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 memory. It features 1344 SPUs along with 112 TAUs and 24 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 660 Ti should in theory be a lot better than the GeForce GTX 460 1GB in general. (explain)
Texel RateThe GeForce GTX 660 Ti will be a lot (about 171%) better at texture filtering than the GeForce GTX 460 1GB. (explain)
Pixel RateThe GeForce GTX 660 Ti should be just a bit (about 2%) more effective at AA than the GeForce GTX 460 1GB, and capable of handling higher 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling 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 chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
