GeForce 930M vs GeForce GTS 250 1GB

Intro

Compare those specs to the GeForce GTS 250 1GB, which comes with GPU clock speed of 738 MHz, and 1024 MB of GDDR3 RAM set to run at 1100 MHz through a 256-bit bus. It also features 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTS 250 1GB should in theory perform quite a bit faster than the GeForce 930M overall. (explain)

GeForce GTS 250 1GB		70400 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 56000 (389%)

Texel Rate

The GeForce GTS 250 1GB should be quite a bit (about 112%) more effective at texture filtering than the GeForce 930M. (explain)

GeForce GTS 250 1GB		47232 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 24960 (112%)

Pixel Rate

The GeForce GTS 250 1GB will be a lot (approximately 59%) better at FSAA than the GeForce 930M, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTS 250 1GB		11808 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 4384 (59%)

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 (measured in MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. 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 are applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. 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 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.
