Compare any two graphics cards:
GeForce GT 130 vs Radeon HD 6450 (OEM)
IntroThe GeForce GT 130 has core clock speeds of 500 MHz on the GPU, and 250 MHz on the 768 MB of DDR2 RAM. It features 48 SPUs along with 24 Texture Address Units and 16 Rasterization Operator Units.Compare all of that to the Radeon HD 6450 (OEM), which has GPU core speed of 625 MHz, and 512 MB of GDDR3 memory set to run at 800 MHz through a 64-bit bus. It also is made up of 160 Stream Processors, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6450 (OEM) should theoretically be a bit better than the GeForce GT 130 overall. (explain)
Texel RateThe GeForce GT 130 will be quite a bit (approximately 140%) faster with regards to anisotropic filtering than the Radeon HD 6450 (OEM). (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GT 130 is a better choice, by a large margin. (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 max amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated 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 graphics 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 the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
