GeForce GT 430 1GB vs GeForce GTX 460 SE

Intro

Compare those specs to the GeForce GTX 460 SE, which makes use of a 40 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR5 memory is set to run at a frequency of 850 MHz on this specific card. It features 288 SPUs along with 48 TAUs and 32 ROPs.

	Difference: 90 Watts (150%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 SE should be 278% quicker than the GeForce GT 430 1GB in general, because of its greater data rate. (explain)

GeForce GTX 460 SE		108800 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 80000 (278%)

Texel Rate

The GeForce GTX 460 SE will be a lot (about 179%) more effective at AF than the GeForce GT 430 1GB. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 20000 (179%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 SE is superior to the GeForce GT 430 1GB, by a large margin. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GT 430 1GB		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 data (in units of MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied 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 higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core 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 rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
