Compare any two graphics cards:
GeForce GT 315 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GT 315 makes use of a 40 nm design. nVidia has set the core speed at 625 MHz. The DDR3 RAM works at a speed of 790 MHz on this specific card. It features 48 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.Compare those specs to the Radeon HD 6450 (OEM) 1GB, which comes with core clock speeds of 750 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 memory. It features 160 SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6450 (OEM) 1GB should perform just a bit faster than the GeForce GT 315 overall. (explain)
Texel RateThe GeForce GT 315 is quite a bit (about 67%) faster with regards to texture filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateThe GeForce GT 315 will be much (approximately 67%) more effective at anti-aliasing than the Radeon HD 6450 (OEM) 1GB, and also should be capable of handling higher resolutions while still performing well. (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 largest amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
