GeForce 9500 GT DDR2 vs GeForce 9800 GT 1GB

Intro

Compare all of that to the GeForce 9800 GT 1GB, which comes with a core clock speed of 600 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 256-bit bus, and uses a 65/55 nm design. It features 112 SPUs, 56 TAUs, and 16 ROPs.

Texel Rate

The GeForce 9800 GT 1GB is a lot (approximately 282%) better at AF than the GeForce 9500 GT DDR2. (explain)

GeForce 9800 GT 1GB		33600 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 24800 (282%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 9800 GT 1GB is a better choice, by far. (explain)

GeForce 9800 GT 1GB		9600 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 5200 (118%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 can be processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
