GeForce 930M vs GeForce GTX 460 1GB

Intro

Compare all that to the GeForce GTX 460 1GB, which features GPU clock speed of 675 MHz, and 1024 MB of GDDR5 memory set to run at 900 MHz through a 256-bit bus. It also is comprised of 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.

GeForce 930M		22272 Mtexels/sec
	Difference: 15528 (70%)

Pixel Rate

The GeForce GTX 460 1GB is a lot (about 191%) better at AA than the GeForce 930M, and capable of handling higher resolutions better. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 14176 (191%)

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 max amount of data (measured in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
