Compare any two graphics cards:
GeForce GT 450 (OEM) vs GeForce GTX 280
IntroThe GeForce GT 450 (OEM) has a clock frequency of 790 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 192-bit bus, and uses a 40 nm design. It is made up of 144 SPUs, 24 Texture Address Units, and 24 ROPs.Compare those specs to the GeForce GTX 280, which features GPU core speed of 602 MHz, and 1024 MB of GDDR3 memory running at 1107 MHz through a 512-bit bus. It also features 240 SPUs, 80 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 280 should in theory be much superior to the GeForce GT 450 (OEM) in general. (explain)
Texel RateThe GeForce GTX 280 should be quite a bit (about 154%) faster with regards to texture filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 280 is the winner, 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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video 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 the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
