GeForce GT 430 vs GeForce GTX 460 SE

Intro

Compare all of that to the GeForce GTX 460 SE, which features GPU clock speed of 650 MHz, and 1024 MB of GDDR5 memory running at 850 MHz through a 256-bit bus. It also is comprised of 288 SPUs, 48 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 SE will be 278% faster than the GeForce GT 430 overall, because of its greater data rate. (explain)

GeForce GTX 460 SE		108800 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 80000 (278%)

Texel Rate

The GeForce GTX 460 SE is a lot (approximately 179%) more effective at anisotropic filtering than the GeForce GT 430. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 20000 (179%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 460 SE is a better choice, by far. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 18000 (643%)

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 information (measured in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, 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 amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
