Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 6450 (OEM)
IntroThe GeForce GTS 450 1GB comes with clock speeds of 783 MHz on the GPU, and 902 MHz on the 1024 MB of GDDR5 RAM. It features 192 SPUs along with 32 Texture Address Units and 16 ROPs.Compare those specifications to the Radeon HD 6450 (OEM), which uses a 40 nm design. AMD has clocked the core frequency at 625 MHz. The GDDR3 memory runs at a speed of 800 MHz on this particular card. It features 160 SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTS 450 1GB should be a lot faster than the Radeon HD 6450 (OEM) overall. (explain)
Texel RateThe GeForce GTS 450 1GB will be quite a bit (approximately 401%) more effective at texture filtering than the Radeon HD 6450 (OEM). (explain)
Pixel RateThe GeForce GTS 450 1GB is much (more or less 401%) more effective at full screen anti-aliasing than the Radeon HD 6450 (OEM), and also should be capable of handling higher screen resolutions better. (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 largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
