GeForce 930M vs GeForce GTS 250 1GB

Intro

Compare those specifications to the GeForce GTS 250 1GB, which has 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 is comprised of 128 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTS 250 1GB should be quite a bit faster than the GeForce 930M in general. (explain)

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

Texel Rate

The GeForce GTS 250 1GB will be a lot (more or less 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 (about 59%) more effective at AA than the GeForce 930M, and able to handle higher resolutions more effectively. (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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred over 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 must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
