GeForce 920M vs GeForce 9500 GT DDR2

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 9500 GT DDR2 should perform a small bit faster than the GeForce 920M in general. (explain)

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

Texel Rate

The GeForce 920M will be quite a bit (approximately 247%) better at AF than the GeForce 9500 GT DDR2. (explain)

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

Pixel Rate

The GeForce 920M should be much (about 73%) better at full screen anti-aliasing than the GeForce 9500 GT DDR2, and also capable of handling higher resolutions without slowing down too much. (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 data (measured in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's bus 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 higher the card's memory bandwidth, 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 number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
