GeForce GTX 650 Ti vs Radeon HD 3470 512MB

Intro

Compare all that to the Radeon HD 3470 512MB, which comes with a core clock speed of 800 MHz and a GDDR3 memory speed of 950 MHz. It also uses a 128-bit bus, and uses a 55 nm design. It is comprised of 40(8x5) SPUs, 4 Texture Address Units, and 4 Raster Operation Units.

Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 56192 (1756%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 650 Ti is a better choice, by a large margin. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 11648 (364%)

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 information (measured in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out 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 drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
