GeForce GT 340 1GB vs GeForce GTX 970

Intro

Compare those specifications to the GeForce GTX 970, which has GPU core speed of 1050 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 256-bit bus. It also features 1664 SPUs, 104 TAUs, and 64 Raster Operation Units.

GeForce GT 340 1GB		54400 MB/sec
	Difference: 169600 (312%)

Texel Rate

The GeForce GTX 970 is a lot (more or less 520%) faster with regards to anisotropic filtering than the GeForce GT 340 1GB. (explain)

GeForce GTX 970		109200 Mtexels/sec
GeForce GT 340 1GB		17600 Mtexels/sec
	Difference: 91600 (520%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 970 is a better choice, and very much so. (explain)

GeForce GTX 970		67200 Mpixels/sec
GeForce GT 340 1GB		4400 Mpixels/sec
	Difference: 62800 (1427%)

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 largest amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that can be processed per 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 higher the texel rate, the better the graphics 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 number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
