GeForce GT 430 vs GeForce GTX 460 SE

Intro

Compare that to the GeForce GTX 460 SE, which makes use of a 40 nm design. nVidia has set the core frequency at 650 MHz. The GDDR5 RAM is set to run at a frequency of 850 MHz on this specific model. It features 288 SPUs along with 48 Texture Address Units and 32 Rasterization Operator Units.

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

Memory Bandwidth

In theory, the GeForce GTX 460 SE will be 278% quicker than the GeForce GT 430 in general, due to 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 (about 179%) faster with regards to 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 using a high screen resolution is important to you, then the GeForce GTX 460 SE is a better choice, and very much so. (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 maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
