GeForce 930M vs GeForce GTX 260

Intro

Compare that to the GeForce GTX 260, which comes with a clock frequency of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also makes use of a 448-bit bus, and uses a 65 nm design. It features 192 SPUs, 64 TAUs, and 28 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 260 should perform a lot faster than the GeForce 930M in general. (explain)

GeForce GTX 260		111888 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 97488 (677%)

Texel Rate

The GeForce GTX 260 is a lot (about 66%) faster with regards to texture filtering than the GeForce 930M. (explain)

GeForce GTX 260		36864 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 14592 (66%)

Pixel Rate

The GeForce GTX 260 should be much (approximately 117%) better at full screen anti-aliasing than the GeForce 930M, and also should be capable of handling higher resolutions better. (explain)

GeForce GTX 260		16128 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 8704 (117%)

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 data (in units of MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
