Compare any two graphics cards:
GeForce GT 450 (OEM) vs Radeon HD 7790
IntroThe GeForce GT 450 (OEM) uses a 40 nm design. nVidia has clocked the core frequency at 790 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this particular card. It features 144 SPUs as well as 24 TAUs and 24 Rasterization Operator Units.Compare those specifications to the Radeon HD 7790, which has a clock speed of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same memory bandwidth, so theoretically they should perform exactly the same. (explain)
Texel RateThe Radeon HD 7790 is a lot (more or less 195%) more effective at texture filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GT 450 (OEM) is a better choice, but not 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once 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 AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
