Compare any two graphics cards:
GeForce GT 430 1GB vs GeForce GTX 650
IntroThe GeForce GT 430 1GB features a clock speed of 700 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It features 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.
Compare those specs to the GeForce GTX 650, which uses a 28 nm design. nVidia has clocked the core speed at 1058 MHz. The GDDR5 RAM works at a frequency of 1250 MHz on this card. It features 384 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 650 should in theory be a lot superior to the GeForce GT 430 1GB in general. (explain)
Texel RateThe GeForce GTX 650 is quite a bit (approximately 202%) faster with regards to texture filtering than the GeForce GT 430 1GB. (explain)
Pixel RateThe GeForce GTX 650 is much (approximately 505%) better at AA than the GeForce GT 430 1GB, and also 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 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 maximum amount of data (counted in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock 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 per second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
