GeForce 9800 GTX+ vs GeForce GT 440 3GB

Intro

Compare all that to the GeForce GT 440 3GB, which features a clock speed of 594 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 192-bit memory bus, and makes use of a 40 nm design. It is made up of 144 SPUs, 24 TAUs, and 24 ROPs.

Texel Rate

The GeForce 9800 GTX+ is quite a bit (about 231%) more effective at texture filtering than the GeForce GT 440 3GB. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 32976 (231%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 440 3GB is a better choice, by far. (explain)

GeForce GT 440 3GB		14256 Mpixels/sec
GeForce 9800 GTX+		11808 Mpixels/sec

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
