GeForce 9500 GT DDR2 vs GeForce GT 340 1GB

Intro

The GeForce 9500 GT DDR2 has a GPU core speed of 550 MHz, and the 256 MB of DDR2 memory is set to run at 500 MHz through a 128-bit bus. It also is comprised of 32 Stream Processors, 16 TAUs, and 8 Raster Operation Units.

Compare all that to the GeForce GT 340 1GB, which has core speeds of 550 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 96 SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT DDR2 50 Watts
GeForce GT 340 1GB 69 Watts
Difference: 19 Watts (38%)

Memory Bandwidth

In theory, the GeForce GT 340 1GB will be 240% faster than the GeForce 9500 GT DDR2 overall, due to its higher bandwidth. (explain)

GeForce GT 340 1GB 54400 MB/sec
GeForce 9500 GT DDR2 16000 MB/sec
Difference: 38400 (240%)

Texel Rate

The GeForce GT 340 1GB is a lot (more or less 100%) better at anisotropic filtering than the GeForce 9500 GT DDR2. (explain)

GeForce GT 340 1GB 17600 Mtexels/sec
GeForce 9500 GT DDR2 8800 Mtexels/sec
Difference: 8800 (100%)

Pixel Rate

Both cards have the exact same pixel rate, so in theory they should perform equally good at at full screen 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 information (measured in MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure 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 drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
