GeForce GT 450 (OEM) vs Nvidia Titan X

Intro

Compare those specifications to the Nvidia Titan X, which comes with a clock frequency of 1417 MHz and a GDDR5X memory speed of 1251 MHz. It also uses a 384-bit bus, and uses a 16 nm design. It is made up of 3584 SPUs, 224 Texture Address Units, and 96 ROPs.

GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 395520 (412%)

Texel Rate

The Nvidia Titan X is quite a bit (approximately 1574%) more effective at texture filtering than the GeForce GT 450 (OEM). (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 298448 (1574%)

Pixel Rate

The Nvidia Titan X will be much (more or less 617%) better at AA than the GeForce GT 450 (OEM), and will be capable of handling higher resolutions better. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GT 450 (OEM)		18960 Mpixels/sec
	Difference: 117072 (617%)

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: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
