GeForce GT 440 3GB vs Radeon HD 3470 512MB

Intro

Compare all of that to the Radeon HD 3470 512MB, which uses a 55 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR3 memory is set to run at a speed of 950 MHz on this particular card. It features 40(8x5) SPUs along with 4 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 440 3GB should be 42% quicker than the Radeon HD 3470 512MB overall, due to its greater bandwidth. (explain)

GeForce GT 440 3GB		43200 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 12800 (42%)

Texel Rate

The GeForce GT 440 3GB will be quite a bit (more or less 346%) better at texture filtering than the Radeon HD 3470 512MB. (explain)

GeForce GT 440 3GB		14256 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 11056 (346%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GT 440 3GB is the winner, by far. (explain)

GeForce GT 440 3GB		14256 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 11056 (346%)

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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, 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 calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 potential to reach the max fill rate.
