GeForce 920M vs GeForce GTS 150

Intro

Compare all of that to the GeForce GTS 150, which uses a 55 nm design. nVidia has set the core frequency at 740 MHz. The GDDR3 RAM is set to run at a speed of 500 MHz on this particular card. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTS 150 should perform much faster than the GeForce 920M in general. (explain)

GeForce GTS 150		32000 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 17600 (122%)

Texel Rate

The GeForce GTS 150 is much (approximately 55%) faster with regards to texture filtering than the GeForce 920M. (explain)

GeForce GTS 150		47360 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 16832 (55%)

Pixel Rate

The GeForce GTS 150 should be quite a bit (more or less 55%) better at anti-aliasing than the GeForce 920M, and will be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTS 150		11840 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 4208 (55%)

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 moved over the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock 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 processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
