Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GT 220 GDDR3
IntroThe GeForce 9500 GT DDR2 features a GPU clock speed of 550 MHz, and the 256 MB of DDR2 RAM is set to run at 500 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 Texture Address Units, and 8 ROPs.
Compare those specs to the GeForce GT 220 GDDR3, which makes use of a 40 nm design. nVidia has set the core speed at 625 MHz. The GDDR3 memory is set to run at a speed of 1012 MHz on this specific card. It features 48 SPUs along with 16 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GT 220 GDDR3 should theoretically be a lot faster than the GeForce 9500 GT DDR2 overall. (explain)
Texel RateThe GeForce GT 220 GDDR3 should be a little bit (approximately 14%) better at texture filtering than the GeForce 9500 GT DDR2. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GT 220 GDDR3 is superior to the GeForce 9500 GT DDR2, but only just. (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 largest amount of data (in units of MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the 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 that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. 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 rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
