Compare any two graphics cards:
GeForce GTX 1060 3GB vs GeForce GTX 285 1GB
IntroThe GeForce GTX 1060 3GB has a clock speed of 1506 MHz and a GDDR5 memory frequency of 2000 MHz. It also features a 192-bit bus, and makes use of a 16 nm design. It features 1152 SPUs, 72 Texture Address Units, and 48 Raster Operation Units.
Compare those specs to the GeForce GTX 285 1GB, which has clock speeds of 648 MHz on the GPU, and 1242 MHz on the 1024 MB of GDDR3 RAM. It features 240 SPUs as well as 80 Texture Address Units and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 1060 3GB should theoretically be much better than the GeForce GTX 285 1GB overall. (explain)
Texel RateThe GeForce GTX 1060 3GB should be a lot (approximately 109%) more effective at anisotropic filtering than the GeForce GTX 285 1GB. (explain)
Pixel RateThe GeForce GTX 1060 3GB will be a lot (approximately 249%) more effective at anti-aliasing than the GeForce GTX 285 1GB, 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.
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 max amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 can be applied in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
