Compare any two graphics cards:
GeForce GTX 295 vs Radeon RX 460
IntroThe GeForce GTX 295 uses a 55 nm design. nVidia has set the core frequency at 576 MHz. The GDDR3 memory works at a frequency of 999 MHz on this model. It features 240 SPUs as well as 80 TAUs and 28 Rasterization Operator Units.
Compare those specs to the Radeon RX 460, which comes with a clock speed of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit bus, and uses a 14 nm design. It is made up of 896 SPUs, 56 Texture Address Units, and 16 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 295 should in theory be quite a bit better than the Radeon RX 460 overall. (explain)
Texel RateThe GeForce GTX 295 will be much (more or less 51%) faster with regards to anisotropic filtering than the Radeon RX 460. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 295 is superior to the Radeon RX 460, 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.
One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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 bandwidth is, the lower the ability to get to the max fill rate.
