Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GT 220 GDDR3
IntroThe GeForce 9500 GT DDR2 features a clock frequency of 550 MHz and a DDR2 memory speed of 500 MHz. It also makes use of a 128-bit bus, and uses a 65 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 ROPs.
Compare those specs to the GeForce GT 220 GDDR3, which makes use of a 40 nm design. nVidia has clocked the core frequency at 625 MHz. The GDDR3 RAM is set to run at a frequency of 1012 MHz on this specific card. It features 48 SPUs along with 16 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GT 220 GDDR3, in theory, should perform much faster than the GeForce 9500 GT DDR2 overall. (explain)
Texel RateThe GeForce GT 220 GDDR3 should be just a bit (approximately 14%) faster with regards to AF than the GeForce 9500 GT DDR2. (explain)
Pixel RateThe GeForce GT 220 GDDR3 should be a little bit (approximately 14%) more effective at anti-aliasing than the GeForce 9500 GT DDR2, and will be able to handle higher resolutions without losing too much performance. (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 information (counted in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
