Compare any two graphics cards:
GeForce GT 430 1GB vs GeForce GTX 650
IntroThe GeForce GT 430 1GB features a GPU core clock speed of 700 MHz, and the 1024 MB of GDDR3 memory runs at 900 MHz through a 128-bit bus. It also is made up of 96 Stream Processors, 16 TAUs, and 4 Raster Operation Units.
Compare that to the GeForce GTX 650, which comes with a core clock speed of 1058 MHz and a GDDR5 memory speed of 1250 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is made up of 384 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 650, in theory, should be a lot faster than the GeForce GT 430 1GB in general. (explain)
Texel RateThe GeForce GTX 650 should be a lot (approximately 202%) better at texture filtering than the GeForce GT 430 1GB. (explain)
Pixel RateThe GeForce GTX 650 should be a lot (approximately 505%) faster with regards to AA than the GeForce GT 430 1GB, 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.
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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported over 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 type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
