GeForce GT 430 (OEM) vs GeForce GTX 460 SE

Intro

Compare those specifications to the GeForce GTX 460 SE, which features GPU core speed of 650 MHz, and 1024 MB of GDDR5 RAM set to run at 850 MHz through a 256-bit bus. It also features 288 SPUs, 48 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Performance-wise, the GeForce GTX 460 SE should in theory be quite a bit better than the GeForce GT 430 (OEM) in general. (explain)

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

Texel Rate

The GeForce GTX 460 SE will be quite a bit (approximately 179%) more effective at texture filtering than the GeForce GT 430 (OEM). (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is superior to the GeForce GT 430 (OEM), and very much so. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GT 430 (OEM)		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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the 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 chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. 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 memory bandwidth is, the lower the potential to get to the max fill rate.
