GeForce 930M vs GeForce GTX 280

Intro

Compare those specs to the GeForce GTX 280, which comes with GPU clock speed of 602 MHz, and 1024 MB of GDDR3 RAM set to run at 1107 MHz through a 512-bit bus. It also is made up of 240 SPUs, 80 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 280 should be a lot faster than the GeForce 930M overall. (explain)

GeForce GTX 280		141696 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 127296 (884%)

Texel Rate

The GeForce GTX 280 will be quite a bit (more or less 116%) faster with regards to anisotropic filtering than the GeForce 930M. (explain)

GeForce GTX 280		48160 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 25888 (116%)

Pixel Rate

The GeForce GTX 280 is much (about 159%) faster with regards to FSAA than the GeForce 930M, and also should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 280		19264 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 11840 (159%)

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 maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 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 anti-aliasing, 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 speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
