GeForce GT 340 vs Nvidia Titan X

Intro

Compare those specifications to the Nvidia Titan X, which comes with clock speeds of 1417 MHz on the GPU, and 1251 MHz on the 12288 MB of GDDR5X RAM. It features 3584 SPUs as well as 224 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340		69 Watts
Nvidia Titan X		250 Watts
	Difference: 181 Watts (262%)

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X is 804% faster than the GeForce GT 340 overall, because of its greater bandwidth. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GT 340		54400 MB/sec
	Difference: 437120 (804%)

Texel Rate

The Nvidia Titan X should be quite a bit (more or less 1703%) better at anisotropic filtering than the GeForce GT 340. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 299808 (1703%)

Pixel Rate

If using high levels of AA is important to you, then the Nvidia Titan X is a better choice, by far. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 131632 (2992%)

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 largest amount of data (in units of MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
