GeForce 930M vs GeForce 9500 GT DDR2

Intro

Compare those specifications to the GeForce 9500 GT DDR2, which comes with a GPU core clock speed of 550 MHz, and 256 MB of DDR2 memory set to run at 500 MHz through a 128-bit bus. It also is comprised of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 9500 GT DDR2 should theoretically be a small bit superior to the GeForce 930M overall. (explain)

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

Texel Rate

The GeForce 930M should be a lot (about 153%) more effective at AF 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 should be a lot (more or less 69%) better at full screen anti-aliasing than the GeForce 9500 GT DDR2, and also should be able to handle higher 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 data (counted in megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
