Compare any two graphics cards:
GeForce GTX 1060 3GB vs Radeon HD 6950 2GB
IntroThe GeForce GTX 1060 3GB has a core clock frequency of 1506 MHz and a GDDR5 memory speed of 2000 MHz. It also uses a 192-bit memory bus, and makes use of a 16 nm design. It features 1152 SPUs, 72 TAUs, and 48 Raster Operation Units.
Compare that to the Radeon HD 6950 2GB, which uses a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory runs at a frequency of 1250 MHz on this specific card. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 1060 3GB, in theory, should perform quite a bit faster than the Radeon HD 6950 2GB overall. (explain)
Texel RateThe GeForce GTX 1060 3GB will be quite a bit (more or less 54%) better at anisotropic filtering than the Radeon HD 6950 2GB. (explain)
Pixel RateThe GeForce GTX 1060 3GB should be quite a bit (approximately 182%) faster with regards to AA than the Radeon HD 6950 2GB, and capable of handling 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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can 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 Raster Operations Pipelines by the the core 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 - the lower the bandwidth is, the lower the potential to get to the max fill rate.
