Compare any two graphics cards:
GeForce GTX 650 Ti 2GB vs Radeon HD 4890 2GB
IntroThe GeForce GTX 650 Ti 2GB comes with a core clock speed of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is comprised of 768 SPUs, 64 TAUs, and 16 ROPs.Compare all of that to the Radeon HD 4890 2GB, which comes with a core 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 features 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 4890 2GB should in theory be a lot superior to the GeForce GTX 650 Ti 2GB in general. (explain)
Texel RateThe GeForce GTX 650 Ti 2GB will be quite a bit (more or less 48%) faster with regards to texture filtering than the Radeon HD 4890 2GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 4890 2GB is a better choice, not by a very large margin though. (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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high 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 number 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 processed per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
