GeForce GT 440 1.5GB vs GeForce GTX 460 (OEM)

Intro

Compare those specifications to the GeForce GTX 460 (OEM), which features a core clock frequency of 650 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 256-bit memory bus, and uses a 40 nm design. It is made up of 336 SPUs, 56 Texture Address Units, and 32 ROPs.

	Difference: 65600 (152%)

Texel Rate

The GeForce GTX 460 (OEM) is much (about 155%) more effective at anisotropic filtering than the GeForce GT 440 1.5GB. (explain)

GeForce GTX 460 (OEM)		36400 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 22144 (155%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 (OEM) is superior to the GeForce GT 440 1.5GB, and very much so. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
GeForce GT 440 1.5GB		14256 Mpixels/sec
	Difference: 6544 (46%)

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 (counted in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
