GeForce 920M vs GeForce 9500 GT DDR2

Intro

Compare all that to the GeForce 9500 GT DDR2, which has a clock speed of 550 MHz and a DDR2 memory frequency of 500 MHz. It also makes use of a 128-bit bus, and uses a 65 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 9500 GT DDR2 should theoretically perform a small bit faster than the GeForce 920M overall. (explain)

GeForce 9500 GT DDR2		16000 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The GeForce 920M will be a lot (more or less 247%) better at texture filtering than the GeForce 9500 GT DDR2. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 21728 (247%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 920M is the winner, by a large margin. (explain)

GeForce 920M		7632 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 3232 (73%)

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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to 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 max fill rate.
