GeForce 9500 GT DDR2 vs GeForce GT 340 1GB
Intro
The GeForce 9500 GT DDR2 uses a 65 nm design. nVidia has clocked the core frequency at 550 MHz. The DDR2 RAM works at a frequency of 500 MHz on this specific card. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare those specifications to the GeForce GT 340 1GB, which comes with GPU clock speed of 550 MHz, and 1024 MB of GDDR5 memory running at 850 MHz through a 128-bit bus. It also features 96 SPUs, 32 Texture Address Units, and 8 ROPs.

Pixel Rate
Both cards have the exact same pixel fill rate, so theoretically they should be equally good at at anti-aliasing, and be able to handle the same screen resolutions. (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.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 are applied per second. This number is worked out by multiplying the total texture units of the card 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 per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
