Compare any two graphics cards:
GeForce GTX 1060 3GB vs Radeon R9 285
IntroThe GeForce GTX 1060 3GB features core clock speeds of 1506 MHz on the GPU, and 2000 MHz on the 3072 MB of GDDR5 memory. It features 1152 SPUs as well as 72 Texture Address Units and 48 Rasterization Operator Units.
Compare those specs to the Radeon R9 285, which has GPU clock speed of 918 MHz, and 2048 MB of GDDR5 memory running at 1375 MHz through a 256-bit bus. It also is comprised of 1792 Stream Processors, 112 Texture Address Units, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 1060 3GB should perform a little bit faster than the Radeon R9 285 in general. (explain)
Texel RateThe GeForce GTX 1060 3GB should be a little bit (approximately 5%) better at anisotropic filtering than the Radeon R9 285. (explain)
Pixel RateThe GeForce GTX 1060 3GB will be quite a bit (about 146%) faster with regards to full screen anti-aliasing than the Radeon R9 285, and will be capable of handling higher resolutions better. (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 data (measured in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated 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 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 number of pixels the video card can possibly write to the local memory per 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 - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 ability to get to the maximum fill rate.
