Compare any two graphics cards:
GeForce 8500 GT vs GeForce GTX 1060 3GB
IntroThe GeForce 8500 GT makes use of a 80 nm design. nVidia has set the core speed at 450 MHz. The DDR2 memory runs at a frequency of 400 MHz on this particular model. It features 16 SPUs as well as 8 TAUs and 4 ROPs.
Compare that to the GeForce GTX 1060 3GB, which makes use of a 16 nm design. nVidia has clocked the core frequency at 1506 MHz. The GDDR5 memory works at a frequency of 2000 MHz on this specific card. It features 1152 SPUs along with 72 TAUs and 48 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 1060 3GB should be 1436% quicker than the GeForce 8500 GT overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 1060 3GB will be quite a bit (more or less 2912%) more effective at AF than the GeForce 8500 GT. (explain)
Pixel RateThe GeForce GTX 1060 3GB should be much (approximately 3916%) faster with regards to AA than the GeForce 8500 GT, and will be capable of handling 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: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of 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 worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
