Compare any two graphics cards:
GeForce GTX 1060 3GB vs GeForce GTX 970
IntroThe GeForce GTX 1060 3GB comes with 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 TAUs and 48 ROPs.
Compare those specs to the GeForce GTX 970, which features core clock speeds of 1050 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 1664 SPUs as well as 104 TAUs and 64 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 970, in theory, should perform a bit faster than the GeForce GTX 1060 3GB overall. (explain)
Texel RateThe GeForce GTX 970 is a little bit (approximately 1%) better at texture filtering than the GeForce GTX 1060 3GB. (explain)
Pixel RateThe GeForce GTX 1060 3GB is just a bit (about 8%) better at full screen anti-aliasing than the GeForce GTX 970, and also able to handle higher screen resolutions more effectively. (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 (counted in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
