GeForce GT 230 vs GeForce GTX 970

Intro

Compare those specifications to the GeForce GTX 970, which has a core clock frequency of 1050 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It is made up of 1664 SPUs, 104 TAUs, and 64 Raster Operation Units.

GeForce GT 230		65 Watts
GeForce GTX 970		145 Watts
	Difference: 80 Watts (123%)

Memory Bandwidth

The GeForce GTX 970, in theory, should be much faster than the GeForce GT 230 overall. (explain)

GeForce GTX 970		224000 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 185600 (483%)

Texel Rate

The GeForce GTX 970 will be a lot (more or less 1141%) better at anisotropic filtering than the GeForce GT 230. (explain)

GeForce GTX 970		109200 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 100400 (1141%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 970 is a better choice, by far. (explain)

GeForce GTX 970		67200 Mpixels/sec
GeForce GT 230		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 max amount of information (in units of MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
