Compare any two graphics cards:
GeForce GTX 1060 3GB vs Radeon HD 6950
IntroThe GeForce GTX 1060 3GB features a core clock frequency of 1506 MHz and a GDDR5 memory frequency of 2000 MHz. It also features a 192-bit bus, and uses a 16 nm design. It is comprised of 1152 SPUs, 72 TAUs, and 48 Raster Operation Units.
Compare that to the Radeon HD 6950, which features a GPU core clock speed of 800 MHz, and 1024 MB of GDDR5 RAM running at 1250 MHz through a 256-bit bus. It also features 1408 Stream Processors, 88 TAUs, and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 1060 3GB should perform a lot faster than the Radeon HD 6950 overall. (explain)
Texel RateThe GeForce GTX 1060 3GB is quite a bit (approximately 54%) more effective at texture filtering than the Radeon HD 6950. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 1060 3GB is a better choice, and very much so. (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 maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video 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 number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
