GeForce 9500 GT DDR2 vs GeForce GTX 870M

Intro

Compare those specifications to the GeForce GTX 870M, which makes use of a 28 nm design. nVidia has clocked the core frequency at 941 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this specific card. It features 1344 SPUs as well as 112 TAUs and 24 ROPs.

GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 80000 (500%)

Texel Rate

The GeForce GTX 870M will be a lot (more or less 1098%) faster with regards to anisotropic filtering than the GeForce 9500 GT DDR2. (explain)

GeForce GTX 870M		105392 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 96592 (1098%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 870M is superior to the GeForce 9500 GT DDR2, by a large margin. (explain)

GeForce GTX 870M		22584 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 18184 (413%)

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 data (counted in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). 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 maximum fill rate.
