Compare any two graphics cards:
GeForce GT 430 vs Radeon HD 7750
IntroThe GeForce GT 430 features a GPU core speed of 700 MHz, and the 512 MB of GDDR3 RAM is set to run at 900 MHz through a 128-bit bus. It also features 96 Stream Processors, 16 Texture Address Units, and 4 ROPs.
Compare all of that to the Radeon HD 7750, which comes with a core clock frequency of 800 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is made up of 512 SPUs, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon HD 7750 is 150% faster than the GeForce GT 430 in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 7750 will be a lot (approximately 129%) faster with regards to AF than the GeForce GT 430. (explain)
Pixel RateThe Radeon HD 7750 should be quite a bit (more or less 357%) more effective at anti-aliasing than the GeForce GT 430, and should 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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
