GeForce 920M vs GeForce GTX 260 216SP 55 nm

Intro

Compare all of that to the GeForce GTX 260 216SP 55 nm, which uses a 55 nm design. nVidia has set the core frequency at 576 MHz. The GDDR3 RAM works at a frequency of 999 MHz on this card. It features 216 SPUs along with 72 Texture Address Units and 28 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 260 216SP 55 nm should be 677% faster than the GeForce 920M overall, due to its higher bandwidth. (explain)

GeForce GTX 260 216SP 55 nm		111888 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 97488 (677%)

Texel Rate

The GeForce GTX 260 216SP 55 nm is a lot (approximately 36%) more effective at anisotropic filtering than the GeForce 920M. (explain)

GeForce GTX 260 216SP 55 nm		41472 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 10944 (36%)

Pixel Rate

The GeForce GTX 260 216SP 55 nm will be much (approximately 111%) faster with regards to anti-aliasing than the GeForce 920M, and also should be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 260 216SP 55 nm		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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number 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 Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
