GeForce GTX 560 Ti vs Radeon HD 3470 256MB

Intro

Compare all of that to the Radeon HD 3470 256MB, which makes use of a 55 nm design. AMD has clocked the core frequency at 800 MHz. The DDR2 memory is set to run at a frequency of 950 MHz on this specific card. It features 40(8x5) SPUs as well as 4 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 Ti should be 322% faster than the Radeon HD 3470 256MB overall, due to its higher data rate. (explain)

GeForce GTX 560 Ti		128256 MB/sec
Radeon HD 3470 256MB		30400 MB/sec
	Difference: 97856 (322%)

Texel Rate

The GeForce GTX 560 Ti will be a lot (more or less 1544%) better at AF than the Radeon HD 3470 256MB. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
Radeon HD 3470 256MB		3200 Mtexels/sec
	Difference: 49408 (1544%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 560 Ti is the winner, by far. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
Radeon HD 3470 256MB		3200 Mpixels/sec
	Difference: 23104 (722%)

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 (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
