GeForce GT 430 1GB vs GeForce GTX 460

Intro

Compare those specifications to the GeForce GTX 460, which comes with GPU core speed of 675 MHz, and 768 MB of GDDR5 memory set to run at 900 MHz through a 192-bit bus. It also features 336 Stream Processors, 56 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430 1GB		60 Watts
GeForce GTX 460		150 Watts
	Difference: 90 Watts (150%)

Memory Bandwidth

Performance-wise, the GeForce GTX 460 should theoretically be a lot superior to the GeForce GT 430 1GB in general. (explain)

GeForce GTX 460		86400 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 57600 (200%)

Texel Rate

The GeForce GTX 460 should be quite a bit (about 238%) more effective at texture filtering than the GeForce GT 430 1GB. (explain)

GeForce GTX 460		37800 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 26600 (238%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 460 is a better choice, and very much so. (explain)

GeForce GTX 460		16200 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 13400 (479%)

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 (measured in megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
