GeForce 9500 GT 512MB GDDR3 vs GeForce GTX 950M

Intro

Compare that to the GeForce GTX 950M, which makes use of a 28 nm design. nVidia has set the core speed at 914 MHz. The DDR3 RAM runs at a frequency of 1000 MHz on this particular model. It features 640 SPUs along with 40 TAUs and 16 ROPs.

GeForce GTX 950M		55 Watts
	Difference: 5 Watts (10%)

Memory Bandwidth

Theoretically, the GeForce GTX 950M should perform much faster than the GeForce 9500 GT 512MB GDDR3 in general. (explain)

GeForce GTX 950M		32000 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 6400 (25%)

Texel Rate

The GeForce GTX 950M will be much (more or less 315%) faster with regards to anisotropic filtering than the GeForce 9500 GT 512MB GDDR3. (explain)

GeForce GTX 950M		36560 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 27760 (315%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 950M is a better choice, by far. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce 9500 GT 512MB GDDR3		4400 Mpixels/sec
	Difference: 10224 (232%)

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 max amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
