Compare any two graphics cards:
GeForce GTX 960 vs Radeon HD 4890 2GB
IntroThe GeForce GTX 960 features a core clock frequency of 1127 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is made up of 1024 SPUs, 64 TAUs, and 32 ROPs.Compare those specifications to the Radeon HD 4890 2GB, which has a clock frequency of 1000 MHz and a GDDR5 memory speed of 975 MHz. It also uses a 256-bit memory bus, and uses a 55 nm design. It is made up of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 4890 2GB should in theory be a little bit superior to the GeForce GTX 960 in general. (explain)
Texel RateThe GeForce GTX 960 should be quite a bit (more or less 80%) faster with regards to anisotropic filtering than the Radeon HD 4890 2GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 960 is superior to the Radeon HD 4890 2GB, 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
