Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce 9500 GT 512MB GDDR3 comes with core speeds of 550 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 memory. It features 32 SPUs along with 16 TAUs and 8 ROPs.Compare those specifications to the Radeon HD 6450 (OEM) 1GB, which has a clock speed of 750 MHz and a GDDR5 memory frequency of 900 MHz. It also features a 64-bit bus, and uses a 40 nm design. It is made up of 160 SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6450 (OEM) 1GB should theoretically be a little bit better than the GeForce 9500 GT 512MB GDDR3 overall. (explain)
Texel RateThe GeForce 9500 GT 512MB GDDR3 will be a lot (approximately 47%) better at AF than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 9500 GT 512MB GDDR3 is a better choice, 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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that are applied per second. This number is worked out 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 in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
