Compare any two graphics cards:
GeForce GTS 450 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTS 450 makes use of a 40 nm design. nVidia has set the core frequency at 783 MHz. The GDDR5 RAM is set to run at a speed of 902 MHz on this particular card. It features 192 SPUs as well as 32 Texture Address Units and 16 ROPs.Compare those specifications to the Radeon HD 6450 (OEM) 1GB, which uses a 40 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 memory works at a speed of 900 MHz on this particular card. It features 160 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTS 450 should theoretically perform much faster than the Radeon HD 6450 (OEM) 1GB in general. (explain)
Texel RateThe GeForce GTS 450 should be a lot (approximately 318%) better at texture filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTS 450 is a better choice, and very much so. (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 maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, the result should 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, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core 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 in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to 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 get to the max fill rate.
