GeForce GT 340 vs GeForce GTX Titan X

Intro

Compare those specifications to the GeForce GTX Titan X, which features a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 384-bit bus, and uses a 28 nm design. It is comprised of 3072 SPUs, 192 Texture Address Units, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically, the GeForce GTX Titan X should be quite a bit faster than the GeForce GT 340 in general. (explain)

GeForce GTX Titan X		336000 MB/sec
GeForce GT 340		54400 MB/sec
	Difference: 281600 (518%)

Texel Rate

The GeForce GTX Titan X is quite a bit (approximately 991%) faster with regards to anisotropic filtering than the GeForce GT 340. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 174400 (991%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX Titan X is superior to the GeForce GT 340, and very much so. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 91600 (2082%)

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 megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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 memory bandwidth is, the lower the potential to reach the max fill rate.
