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 makes use of a 192-bit bus, and uses a 16 nm design. It is made up of 1152 SPUs, 72 TAUs, and 48 Raster Operation Units.
Compare those specs to the GeForce GTX 285 1GB, which comes with clock speeds of 648 MHz on the GPU, and 1242 MHz on the 1024 MB of GDDR3 RAM. It features 240 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 1060 3GB should theoretically perform a lot faster than the GeForce GTX 285 1GB in general. (explain)
Texel RateThe GeForce GTX 1060 3GB will be much (about 109%) faster with regards to AF than the GeForce GTX 285 1GB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 1060 3GB is superior to the GeForce GTX 285 1GB, by a large margin. (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 MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. 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 rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
