Compare any two graphics cards:
GeForce GTX 1060 3GB vs Radeon HD 6950
IntroThe GeForce GTX 1060 3GB makes use of a 16 nm design. nVidia has set the core frequency at 1506 MHz. The GDDR5 memory runs at a frequency of 2000 MHz on this card. It features 1152 SPUs along with 72 Texture Address Units and 48 Rasterization Operator Units.
Compare all that to the Radeon HD 6950, which has a GPU core clock speed of 800 MHz, and 1024 MB of GDDR5 RAM set to run at 1250 MHz through a 256-bit bus. It also features 1408 SPUs, 88 TAUs, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 1060 3GB will be 23% quicker than the Radeon HD 6950 overall, due to its higher data rate. (explain)
Texel RateThe GeForce GTX 1060 3GB is quite a bit (approximately 54%) better at texture filtering than the Radeon HD 6950. (explain)
Pixel RateThe GeForce GTX 1060 3GB will be quite a bit (more or less 182%) better at full screen anti-aliasing than the Radeon HD 6950, and also 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 largest amount of data (counted in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
