GeForce GT 340 vs GeForce GTX 960

Intro

Compare those specifications to the GeForce GTX 960, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1127 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this particular card. It features 1024 SPUs as well as 64 Texture Address Units 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

In theory, the GeForce GTX 960 is 106% quicker than the GeForce GT 340 overall, because of its higher bandwidth. (explain)

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

Texel Rate

The GeForce GTX 960 is quite a bit (about 310%) faster with regards to 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 the winner, 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: Bandwidth is the max amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
