GeForce 920M vs GeForce GTX 460 SE

Intro

Compare all of that to the GeForce GTX 460 SE, which makes use of a 40 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR5 RAM is set to run at a speed of 850 MHz on this model. It features 288 SPUs as well as 48 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 460 SE should theoretically be quite a bit faster than the GeForce 920M in general. (explain)

GeForce GTX 460 SE		108800 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 94400 (656%)

Texel Rate

The GeForce GTX 460 SE should be a small bit (approximately 2%) faster with regards to texture filtering than the GeForce 920M. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 672 (2%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 460 SE is the winner, and very much so. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 13168 (173%)

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 (in units of MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
