Compare any two graphics cards:
GeForce GT 220 GDDR3 vs GeForce GT 430
IntroThe GeForce GT 220 GDDR3 has a GPU core speed of 625 MHz, and the 512 MB of GDDR3 RAM is set to run at 1012 MHz through a 128-bit bus. It also features 48 SPUs, 16 TAUs, and 8 ROPs.
Compare those specs to the GeForce GT 430, which comes with a clock frequency of 700 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It features 96 SPUs, 16 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GT 220 GDDR3 should theoretically be just a bit superior to the GeForce GT 430 overall. (explain)
Texel RateThe GeForce GT 430 will be a bit (more or less 12%) faster with regards to texture filtering than the GeForce GT 220 GDDR3. (explain)
Pixel RateThe GeForce GT 220 GDDR3 should be a lot (more or less 79%) faster with regards to anti-aliasing than the GeForce GT 430, and also 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 max amount of data (in units of 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 the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
