GeForce 830M vs GeForce GTX 590

Intro

Compare all of that to the GeForce GTX 590, which has a core clock speed of 607 MHz and a GDDR5 memory speed of 855 MHz. It also uses a 384-bit memory bus, and uses a 40 nm design. It features 512 SPUs, 64 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 830M		25 Watts
GeForce GTX 590		365 Watts
	Difference: 340 Watts (1360%)

Memory Bandwidth

The GeForce GTX 590 should in theory be a lot faster than the GeForce 830M overall. (explain)

GeForce GTX 590		328320 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 313920 (2180%)

Texel Rate

The GeForce GTX 590 should be quite a bit (more or less 372%) faster with regards to anisotropic filtering than the GeForce 830M. (explain)

GeForce GTX 590		77696 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 61232 (372%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 590 is superior to the GeForce 830M, by a large margin. (explain)

GeForce GTX 590		58272 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 50040 (608%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure 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 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 that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
