Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon HD 6450 (OEM)
IntroThe GeForce GTS 250 1GB comes with a GPU core speed of 738 MHz, and the 1024 MB of GDDR3 memory runs at 1100 MHz through a 256-bit bus. It also is comprised of 128 Stream Processors, 64 TAUs, and 16 Raster Operation Units.Compare all that to the Radeon HD 6450 (OEM), which features GPU clock speed of 625 MHz, and 512 MB of GDDR3 RAM running at 800 MHz through a 64-bit bus. It also is comprised of 160 SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTS 250 1GB should in theory be much better than the Radeon HD 6450 (OEM) overall. (explain)
Texel RateThe GeForce GTS 250 1GB is quite a bit (about 845%) more effective at anisotropic filtering than the Radeon HD 6450 (OEM). (explain)
Pixel RateThe GeForce GTS 250 1GB will be a lot (approximately 372%) more effective at AA than the Radeon HD 6450 (OEM), and also capable of handling higher resolutions more effectively. (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 moved across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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.
