GeForce 9500 GT 1GB GDDR3 vs GeForce GTX 980M

Intro

Compare those specifications to the GeForce GTX 980M, which uses a 28 nm design. nVidia has set the core speed at 1038 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this card. It features 1536 SPUs as well as 96 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 1GB GDDR3		50 Watts
GeForce GTX 980M		100 Watts
	Difference: 50 Watts (100%)

Memory Bandwidth

Theoretically, the GeForce GTX 980M should perform a lot faster than the GeForce 9500 GT 1GB GDDR3 in general. (explain)

GeForce GTX 980M		128000 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 102400 (400%)

Texel Rate

The GeForce GTX 980M should be a lot (more or less 1032%) faster with regards to anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce GTX 980M		99648 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 90848 (1032%)

Pixel Rate

The GeForce GTX 980M is quite a bit (about 1410%) better at AA than the GeForce 9500 GT 1GB GDDR3, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 980M		66432 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
	Difference: 62032 (1410%)

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 max amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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