GeForce GT 230 vs GeForce GTX 880M

Intro

Compare all that to the GeForce GTX 880M, which uses a 28 nm design. nVidia has set the core frequency at 954 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this specific card. It features 1536 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

GeForce GT 230		8800 Mtexels/sec
	Difference: 113312 (1288%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 880M is superior to the GeForce GT 230, by far. (explain)

GeForce GTX 880M		30528 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 26128 (594%)

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 (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video 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 the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
