Compare any two graphics cards:
GeForce GT 430 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GT 430 uses a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR3 RAM is set to run at a speed of 900 MHz on this model. It features 96 SPUs along with 16 Texture Address Units and 4 ROPs.
Compare those specifications to the Radeon HD 6450 (OEM) 1GB, which features a core clock frequency of 750 MHz and a GDDR5 memory speed of 900 MHz. It also makes use of a 64-bit memory bus, and makes use of a 40 nm design. It is made up of 160 SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Both cards have the exact same bandwidth, so theoretically they should perform the same. (explain)
Texel RateThe GeForce GT 430 is quite a bit (more or less 87%) faster with regards to anisotropic filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateThe Radeon HD 6450 (OEM) 1GB should be a little bit (approximately 7%) better at full screen anti-aliasing than the GeForce GT 430, and will be capable of handling higher screen 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
