Compare any two graphics cards:
GeForce GTX 1060 3GB vs GeForce GTX 285 2GB
IntroThe GeForce GTX 1060 3GB features clock speeds of 1506 MHz on the GPU, and 2000 MHz on the 3072 MB of GDDR5 RAM. It features 1152 SPUs along with 72 TAUs and 48 Rasterization Operator Units.
Compare those specs to the GeForce GTX 285 2GB, which uses a 55 nm design. nVidia has clocked the core frequency at 648 MHz. The GDDR3 RAM is set to run at a speed of 1242 MHz on this model. It features 240 SPUs as well as 80 TAUs and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 1060 3GB should perform much faster than the GeForce GTX 285 2GB overall. (explain)
Texel RateThe GeForce GTX 1060 3GB will be quite a bit (more or less 109%) more effective at texture filtering than the GeForce GTX 285 2GB. (explain)
Pixel RateThe GeForce GTX 1060 3GB will be much (approximately 249%) better at anti-aliasing than the GeForce GTX 285 2GB, and also capable of handling higher resolutions without slowing down too much. (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 information (measured in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
