GeForce GT 340 vs GeForce GTX 960

Intro

Compare those specs to the GeForce GTX 960, which comes with core clock speeds of 1127 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 memory. It features 1024 SPUs as well as 64 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340		69 Watts
GeForce GTX 960		120 Watts
	Difference: 51 Watts (74%)

Memory Bandwidth

Theoretically, the GeForce GTX 960 should perform much faster than the GeForce GT 340 in general. (explain)

GeForce GTX 960		112000 MB/sec
GeForce GT 340		54400 MB/sec
	Difference: 57600 (106%)

Texel Rate

The GeForce GTX 960 should be much (approximately 310%) better at texture filtering than the GeForce GT 340. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 54528 (310%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 960 is superior to the GeForce GT 340, and very much so. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 31664 (720%)

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 max amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
