GeForce 9500 GT 1GB GDDR3 vs GeForce GTX 950M

Intro

Compare those specifications to the GeForce GTX 950M, which uses a 28 nm design. nVidia has clocked the core frequency at 914 MHz. The DDR3 RAM is set to run at a speed of 1000 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 1GB GDDR3		50 Watts
GeForce GTX 950M		55 Watts
	Difference: 5 Watts (10%)

Memory Bandwidth

In theory, the GeForce GTX 950M should perform quite a bit faster than the GeForce 9500 GT 1GB GDDR3 in general. (explain)

GeForce GTX 950M		32000 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 6400 (25%)

Texel Rate

The GeForce GTX 950M will be quite a bit (more or less 315%) more effective at texture filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce GTX 950M		36560 Mtexels/sec
GeForce 9500 GT 1GB 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 the winner, by far. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce 9500 GT 1GB 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 maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount 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 applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. 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 is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
