Compare any two graphics cards:
GeForce GT 130 vs Radeon HD 6450 (OEM)
IntroThe GeForce GT 130 has clock speeds of 500 MHz on the GPU, and 250 MHz on the 768 MB of DDR2 memory. It features 48 SPUs as well as 24 Texture Address Units and 16 Rasterization Operator Units.Compare all of that to the Radeon HD 6450 (OEM), which makes use of a 40 nm design. AMD has set the core frequency at 625 MHz. The GDDR3 RAM works at a speed of 800 MHz on this particular model. It features 160 SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6450 (OEM) should be a bit faster than the GeForce GT 130 in general. (explain)
Texel RateThe GeForce GT 130 will be much (about 140%) more effective at AF than the Radeon HD 6450 (OEM). (explain)
Pixel RateThe GeForce GT 130 should be much (approximately 220%) more effective at anti-aliasing than the Radeon HD 6450 (OEM), and able to handle 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 data (measured in MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 are processed per second. This number is worked out by multiplying the total texture units of the card 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 maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs 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 output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
