GeForce GT 315 vs Nvidia Titan X

Intro

Compare all of that to the Nvidia Titan X, which has clock speeds of 1417 MHz on the GPU, and 1251 MHz on the 12288 MB of GDDR5X RAM. It features 3584 SPUs along with 224 TAUs and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 315		52 Watts
Nvidia Titan X		250 Watts
	Difference: 198 Watts (381%)

Memory Bandwidth

Performance-wise, the Nvidia Titan X should theoretically be quite a bit superior to the GeForce GT 315 in general. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GT 315		25280 MB/sec
	Difference: 466240 (1844%)

Texel Rate

The Nvidia Titan X should be quite a bit (more or less 3074%) more effective at AF than the GeForce GT 315. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GT 315		10000 Mtexels/sec
	Difference: 307408 (3074%)

Pixel Rate

The Nvidia Titan X should be a lot (about 2621%) better at anti-aliasing than the GeForce GT 315, and capable of handling higher screen resolutions while still performing well. (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 maximum amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the 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 maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 get to the max fill rate.
