GeForce GT 230 vs GeForce GT 430 1GB

Intro

Compare those specifications to the GeForce GT 430 1GB, which features core speeds of 700 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 RAM. It features 96 SPUs as well as 16 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430 1GB		60 Watts
GeForce GT 230		65 Watts
	Difference: 5 Watts (8%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 230 should be a lot faster than the GeForce GT 430 1GB in general. (explain)

GeForce GT 230		38400 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 9600 (33%)

Texel Rate

The GeForce GT 430 1GB should be quite a bit (more or less 27%) faster with regards to anisotropic filtering than the GeForce GT 230. (explain)

GeForce GT 430 1GB		11200 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 2400 (27%)

Pixel Rate

The GeForce GT 230 will be much (about 57%) more effective at anti-aliasing than the GeForce GT 430 1GB, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GT 230		4400 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 1600 (57%)

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 largest amount of data (counted in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
