GeForce GT 315 vs Nvidia Titan X

Intro

Compare those specs to the Nvidia Titan X, which has a core 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 TAUs, and 96 ROPs.

GeForce GT 315		10000 Mtexels/sec
	Difference: 307408 (3074%)

Pixel Rate

The Nvidia Titan X will be much (approximately 2621%) more effective at full screen anti-aliasing than the GeForce GT 315, and able to handle higher screen resolutions better. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GT 315		5000 Mpixels/sec
	Difference: 131032 (2621%)

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 largest amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 are processed in one 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can 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 Raster Operations Pipelines 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 lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
