Compare any two graphics cards:
GeForce 9400 GT 256MB vs GeForce GT 130
IntroThe GeForce 9400 GT 256MB features a GPU core clock speed of 550 MHz, and the 256 MB of GDDR2 RAM runs at 400 MHz through a 128-bit bus. It also is made up of 16 SPUs, 8 TAUs, and 4 ROPs.Compare that to the GeForce GT 130, which comes with core speeds of 500 MHz on the GPU, and 250 MHz on the 768 MB of DDR2 RAM. It features 48 SPUs along with 24 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 9400 GT 256MB, in theory, should be a small bit faster than the GeForce GT 130 in general. (explain)
Texel RateThe GeForce GT 130 will be quite a bit (about 173%) better at texture filtering than the GeForce 9400 GT 256MB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GT 130 is superior to the GeForce 9400 GT 256MB, 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 maximum amount of information (counted in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core clock 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 in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
