GeForce 830M vs GeForce GTX Titan X

Intro

Compare that to the GeForce GTX Titan X, which makes use of a 28 nm design. nVidia has set the core frequency at 1000 MHz. The GDDR5 memory works at a speed of 1750 MHz on this particular card. It features 3072 SPUs along with 192 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 830M		25 Watts
GeForce GTX Titan X		250 Watts
	Difference: 225 Watts (900%)

Memory Bandwidth

Theoretically, the GeForce GTX Titan X should perform quite a bit faster than the GeForce 830M overall. (explain)

GeForce GTX Titan X		336000 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 321600 (2233%)

Texel Rate

The GeForce GTX Titan X will be a lot (approximately 1066%) faster with regards to AF than the GeForce 830M. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 175536 (1066%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX Titan X is superior to the GeForce 830M, by far. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 87768 (1066%)

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 (measured in MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, 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, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
