GeForce 8600 GS (OEM) vs GeForce 9500 GT DDR2

Intro

The GeForce 8600 GS (OEM) makes use of a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The DDR2 memory is set to run at a frequency of 400 MHz on this model. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Compare that to the GeForce 9500 GT DDR2, which has GPU core speed of 550 MHz, and 256 MB of DDR2 memory set to run at 500 MHz through a 128-bit bus. It also is comprised of 32 SPUs, 16 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GS (OEM) 47 Watts
GeForce 9500 GT DDR2 50 Watts
Difference: 3 Watts (6%)

Memory Bandwidth

Theoretically speaking, the GeForce 9500 GT DDR2 should be 25% quicker than the GeForce 8600 GS (OEM) overall, because of its higher bandwidth. (explain)

GeForce 9500 GT DDR2 16000 MB/sec
GeForce 8600 GS (OEM) 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The GeForce 9500 GT DDR2 should be a bit (more or less 2%) faster with regards to texture filtering than the GeForce 8600 GS (OEM). (explain)

GeForce 9500 GT DDR2 8800 Mtexels/sec
GeForce 8600 GS (OEM) 8640 Mtexels/sec
Difference: 160 (2%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 9500 GT DDR2 is the winner, though not by far. (explain)

GeForce 9500 GT DDR2 4400 Mpixels/sec
GeForce 8600 GS (OEM) 4320 Mpixels/sec
Difference: 80 (2%)

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 (measured in megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units by the core 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 applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
