GeForce GT 230 vs GeForce GTX 560

Intro

Compare all that to the GeForce GTX 560, which has GPU clock speed of 810 MHz, and 1024 MB of GDDR5 RAM running at 1001 MHz through a 256-bit bus. It also is made up of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce GTX 560 should be quite a bit faster than the GeForce GT 230 overall. (explain)

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

Texel Rate

The GeForce GTX 560 will be much (about 415%) faster with regards to anisotropic filtering than the GeForce GT 230. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 560 is the winner, and very much so. (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: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 are applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
