GeForce GT 315 vs Nvidia Titan X

Intro

Compare those specs to the Nvidia Titan X, which features a clock frequency of 1417 MHz and a GDDR5X memory speed of 1251 MHz. It also makes use of a 384-bit memory bus, and makes use of a 16 nm design. It is comprised of 3584 SPUs, 224 TAUs, and 96 ROPs.

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

As far as performance goes, the Nvidia Titan X should in theory be a lot 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 will be quite a bit (more or less 3074%) faster with regards to 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 will be much (more or less 2621%) faster with regards to full screen anti-aliasing than the GeForce GT 315, and also able to handle higher screen resolutions without losing too much performance. (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 max amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed 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 figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
