GeForce 9500 GT DDR2 vs GeForce GTX 880M

Intro

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

GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 112000 (700%)

Texel Rate

The GeForce GTX 880M will be much (more or less 1288%) better at texture filtering than the GeForce 9500 GT DDR2. (explain)

GeForce GTX 880M		122112 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 113312 (1288%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 880M is the winner, by a large margin. (explain)

GeForce GTX 880M		30528 Mpixels/sec
GeForce 9500 GT DDR2		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 largest amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the 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 number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
