GeForce GT 220 GDDR3 vs Radeon HD 3470 256MB

Intro

Compare all of that to the Radeon HD 3470 256MB, which uses a 55 nm design. AMD has set the core speed at 800 MHz. The DDR2 memory runs at a speed of 950 MHz on this model. It features 40(8x5) SPUs along with 4 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GT 220 GDDR3 should theoretically be just a bit better than the Radeon HD 3470 256MB in general. (explain)

GeForce GT 220 GDDR3		32384 MB/sec
Radeon HD 3470 256MB		30400 MB/sec
	Difference: 1984 (7%)

Texel Rate

The GeForce GT 220 GDDR3 should be much (more or less 213%) better at AF than the Radeon HD 3470 256MB. (explain)

GeForce GT 220 GDDR3		10000 Mtexels/sec
Radeon HD 3470 256MB		3200 Mtexels/sec
	Difference: 6800 (213%)

Pixel Rate

The GeForce GT 220 GDDR3 is quite a bit (more or less 56%) faster with regards to FSAA than the Radeon HD 3470 256MB, and capable of handling higher resolutions without slowing down too much. (explain)

GeForce GT 220 GDDR3		5000 Mpixels/sec
Radeon HD 3470 256MB		3200 Mpixels/sec
	Difference: 1800 (56%)

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 maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many 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.
