GeForce GTX 460 2GB vs GeForce GTX Titan X

Intro

Compare all that to the GeForce GTX Titan X, which features a clock speed of 1000 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 384-bit memory bus, and makes use of a 28 nm design. It is made up of 3072 SPUs, 192 TAUs, and 96 ROPs.

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX Titan X is superior to the GeForce GTX 460 2GB, and very much so. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
GeForce GTX 460 2GB		21600 Mpixels/sec
	Difference: 74400 (344%)

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 (in units of megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number 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 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.
