GeForce 830M vs GeForce GTX 750 Ti

Intro

Compare all of that to the GeForce GTX 750 Ti, which has core speeds of 1020 MHz on the GPU, and 1350 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 830M		25 Watts
GeForce GTX 750 Ti		60 Watts
	Difference: 35 Watts (140%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 Ti should perform a lot faster than the GeForce 830M in general. (explain)

GeForce GTX 750 Ti		86400 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 72000 (500%)

Texel Rate

The GeForce GTX 750 Ti will be much (approximately 148%) faster with regards to AF than the GeForce 830M. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 24336 (148%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 750 Ti is a better choice, and very much so. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 8088 (98%)

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 maximum amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount 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 drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
