GeForce GTX 460 1GB vs GeForce GTX 460 SE

Intro

Compare all of that to the GeForce GTX 460 SE, which comes with core clock speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 memory. It features 288 SPUs as well as 48 Texture Address Units and 32 ROPs.

GeForce GTX 460 SE		150 Watts
GeForce GTX 460 1GB		160 Watts
	Difference: 10 Watts (7%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 1GB should be 6% quicker than the GeForce GTX 460 SE in general, because of its greater bandwidth. (explain)

GeForce GTX 460 1GB		115200 MB/sec
GeForce GTX 460 SE		108800 MB/sec
	Difference: 6400 (6%)

Texel Rate

The GeForce GTX 460 1GB will be quite a bit (approximately 21%) faster with regards to AF than the GeForce GTX 460 SE. (explain)

GeForce GTX 460 1GB		37800 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 6600 (21%)

Pixel Rate

The GeForce GTX 460 1GB will be a small bit (approximately 4%) better at AA than the GeForce GTX 460 SE, and able to handle higher screen resolutions better. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
GeForce GTX 460 SE		20800 Mpixels/sec
	Difference: 800 (4%)

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 largest amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip 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 colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
