GeForce GT 230 vs GeForce GTX 570

Intro

Compare that to the GeForce GTX 570, which has a clock speed of 732 MHz and a GDDR5 memory frequency of 950 MHz. It also features a 320-bit bus, and uses a 40 nm design. It features 480 SPUs, 60 Texture Address Units, and 40 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 230		65 Watts
GeForce GTX 570		219 Watts
	Difference: 154 Watts (237%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 570 should be 296% faster than the GeForce GT 230 in general, due to its higher data rate. (explain)

GeForce GTX 570		152000 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 113600 (296%)

Texel Rate

The GeForce GTX 570 will be quite a bit (more or less 399%) more effective at anisotropic filtering than the GeForce GT 230. (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 35120 (399%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 570 is the winner, by far. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 24880 (565%)

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 maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. 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 also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
