GeForce 930M vs GeForce 9500 GT DDR2

Intro

Compare that to the GeForce 9500 GT DDR2, which makes use of a 65 nm design. nVidia has clocked the core frequency at 550 MHz. The DDR2 RAM is set to run at a speed of 500 MHz on this model. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 9500 GT DDR2 should perform a bit faster than the GeForce 930M in general. (explain)

GeForce 9500 GT DDR2		16000 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The GeForce 930M is much (about 153%) better at anisotropic filtering than the GeForce 9500 GT DDR2. (explain)

GeForce 930M		22272 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 13472 (153%)

Pixel Rate

The GeForce 930M is a lot (more or less 69%) better at AA than the GeForce 9500 GT DDR2, and capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce 930M		7424 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 3024 (69%)

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 largest amount of information (measured in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
