Compare any two graphics cards:
GeForce GTX 1060 3GB vs Radeon HD 6950
IntroThe GeForce GTX 1060 3GB has a GPU core clock speed of 1506 MHz, and the 3072 MB of GDDR5 memory is set to run at 2000 MHz through a 192-bit bus. It also is made up of 1152 SPUs, 72 Texture Address Units, and 48 Raster Operation Units.
Compare those specs to the Radeon HD 6950, which has GPU clock speed of 800 MHz, and 1024 MB of GDDR5 memory set to run at 1250 MHz through a 256-bit bus. It also features 1408 SPUs, 88 TAUs, and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 1060 3GB should in theory be a lot faster than the Radeon HD 6950 overall. (explain)
Texel RateThe GeForce GTX 1060 3GB should be a lot (approximately 54%) faster with regards to anisotropic filtering than the Radeon HD 6950. (explain)
Pixel RateThe GeForce GTX 1060 3GB is quite a bit (more or less 182%) faster with regards to anti-aliasing than the Radeon HD 6950, and will be able to handle higher screen 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 transferred across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be 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 the texel rate, the better the 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 amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of 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.
