Compare any two graphics cards:
GeForce GTX 1060 3GB vs Radeon HD 6970
IntroThe GeForce GTX 1060 3GB makes use of a 16 nm design. nVidia has clocked the core speed at 1506 MHz. The GDDR5 memory is set to run at a frequency of 2000 MHz on this specific card. It features 1152 SPUs along with 72 Texture Address Units and 48 ROPs.
Compare all of that to the Radeon HD 6970, which makes use of a 40 nm design. AMD has clocked the core speed at 880 MHz. The GDDR5 RAM runs at a speed of 1375 MHz on this specific card. It features 1536 SPUs along with 96 Texture Address Units and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 1060 3GB should be 12% faster than the Radeon HD 6970 in general, due to its greater data rate. (explain)
Texel RateThe GeForce GTX 1060 3GB is much (approximately 28%) better at AF than the Radeon HD 6970. (explain)
Pixel RateThe GeForce GTX 1060 3GB is a lot (more or less 157%) better at full screen anti-aliasing than the Radeon HD 6970, 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: Bandwidth is the largest amount of information (measured in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core clock 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 applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
