GeForce 9600 GT 1GB vs GeForce 9800 GTX

Intro

The GeForce 9600 GT 1GB comes with a core clock frequency of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 256-bit bus, and uses a 65/55 nm design. It is made up of 64 SPUs, 32 TAUs, and 16 Raster Operation Units.

Compare those specifications to the GeForce 9800 GTX, which makes use of a 65 nm design. nVidia has set the core speed at 675 MHz. The GDDR3 RAM runs at a frequency of 1100 MHz on this particular model. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GT 1GB 95 Watts
GeForce 9800 GTX 140 Watts
Difference: 45 Watts (47%)

Memory Bandwidth

Theoretically speaking, the GeForce 9800 GTX should be 22% faster than the GeForce 9600 GT 1GB in general, because of its greater data rate. (explain)

GeForce 9800 GTX 70400 MB/sec
GeForce 9600 GT 1GB 57600 MB/sec
Difference: 12800 (22%)

Texel Rate

The GeForce 9800 GTX should be quite a bit (approximately 108%) better at texture filtering than the GeForce 9600 GT 1GB. (explain)

GeForce 9800 GTX 43200 Mtexels/sec
GeForce 9600 GT 1GB 20800 Mtexels/sec
Difference: 22400 (108%)

Pixel Rate

The GeForce 9800 GTX will be just a bit (more or less 4%) better at anti-aliasing than the GeForce 9600 GT 1GB, and also will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce 9800 GTX 10800 Mpixels/sec
GeForce 9600 GT 1GB 10400 Mpixels/sec
Difference: 400 (4%)

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 moved across the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
