GeForce GT 230 vs GeForce GTX 460 1GB

Intro

Compare those specifications to the GeForce GTX 460 1GB, which comes with a GPU core clock speed of 675 MHz, and 1024 MB of GDDR5 memory set to run at 900 MHz through a 256-bit bus. It also is made up of 336 Stream Processors, 56 Texture Address Units, and 32 Raster Operation Units.

GeForce GT 230		8800 Mtexels/sec
	Difference: 29000 (330%)

Pixel Rate

The GeForce GTX 460 1GB is quite a bit (more or less 391%) better at AA than the GeForce GT 230, and also able to handle higher resolutions better. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 17200 (391%)

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 information (in units of MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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