GeForce 920M vs GeForce GTX 260

Intro

Compare those specs to the GeForce GTX 260, which uses a 65 nm design. nVidia has set the core frequency at 576 MHz. The GDDR3 RAM runs at a frequency of 999 MHz on this card. It features 192 SPUs as well as 64 Texture Address Units and 28 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 260 should perform quite a bit faster than the GeForce 920M in general. (explain)

GeForce GTX 260		111888 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 97488 (677%)

Texel Rate

The GeForce GTX 260 will be a lot (about 21%) better at texture filtering than the GeForce 920M. (explain)

GeForce GTX 260		36864 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 6336 (21%)

Pixel Rate

The GeForce GTX 260 should be much (approximately 111%) better at anti-aliasing than the GeForce 920M, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 260		16128 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 8496 (111%)

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 max amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs 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 quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
