VS

GeForce 9600 GT 512MB vs GeForce 9800 GT 512MB

Intro

The GeForce 9600 GT 512MB uses a 65/55 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR3 memory works at a frequency of 900 MHz on this particular card. It features 64 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Compare all of that to the GeForce 9800 GT 512MB, which has a clock frequency of 600 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 256-bit memory bus, and makes use of a 65/55 nm design. It features 112 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GT 512MB 95 Watts
GeForce 9800 GT 512MB 105 Watts
Difference: 10 Watts (11%)

Memory Bandwidth

Both cards have exactly the same bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The GeForce 9800 GT 512MB will be a lot (more or less 62%) more effective at AF than the GeForce 9600 GT 512MB. (explain)

GeForce 9800 GT 512MB 33600 Mtexels/sec
GeForce 9600 GT 512MB 20800 Mtexels/sec
Difference: 12800 (62%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 9600 GT 512MB is a better choice, though not by far. (explain)

GeForce 9600 GT 512MB 10400 Mpixels/sec
GeForce 9800 GT 512MB 9600 Mpixels/sec
Difference: 800 (8%)

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 maximum amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at 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 card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
