GeForce GT 230 vs GeForce GTX 560

Intro

Compare those specifications to the GeForce GTX 560, which comes with GPU core speed of 810 MHz, and 1024 MB of GDDR5 RAM running at 1001 MHz through a 256-bit bus. It also features 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.

GeForce GT 230		65 Watts
GeForce GTX 560		150 Watts
	Difference: 85 Watts (131%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 should perform a lot faster than the GeForce GT 230 in general. (explain)

GeForce GTX 560		128128 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 89728 (234%)

Texel Rate

The GeForce GTX 560 is quite a bit (approximately 415%) more effective at AF than the GeForce GT 230. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 36560 (415%)

Pixel Rate

The GeForce GTX 560 will be a lot (approximately 489%) faster with regards to AA than the GeForce GT 230, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 21520 (489%)

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 (measured in MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
