GeForce 9500 GT 1GB GDDR3 vs GeForce GTX 880M

Intro

Compare all that to the GeForce GTX 880M, which makes use of a 28 nm design. nVidia has clocked the core speed at 954 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this model. It features 1536 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTX 880M		128000 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 102400 (400%)

Texel Rate

The GeForce GTX 880M should be a lot (approximately 1288%) faster with regards to texture filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce GTX 880M		122112 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 113312 (1288%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 880M is a better choice, and very much so. (explain)

GeForce GTX 880M		30528 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		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 MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result 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, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
