Compare any two graphics cards:
GeForce GTX 1060 3GB vs Radeon HD 6950 2GB
IntroThe GeForce GTX 1060 3GB has clock speeds of 1506 MHz on the GPU, and 2000 MHz on the 3072 MB of GDDR5 memory. It features 1152 SPUs along with 72 Texture Address Units and 48 Rasterization Operator Units.
Compare those specifications to the Radeon HD 6950 2GB, which features core speeds of 800 MHz on the GPU, and 1250 MHz on the 2048 MB of GDDR5 memory. It features 1408 SPUs as well as 88 TAUs and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 1060 3GB, in theory, should be quite a bit faster than the Radeon HD 6950 2GB overall. (explain)
Texel RateThe GeForce GTX 1060 3GB is quite a bit (approximately 54%) better at texture filtering than the Radeon HD 6950 2GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 1060 3GB is the winner, by far. (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 information (in units of MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
