GeForce GT 220 GDDR3 vs Radeon HD 5570

Intro

Compare that to the Radeon HD 5570, which comes with core speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of DDR3 RAM. It features 400(80x5) SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5570		43 Watts
GeForce GT 220 GDDR3		58 Watts
	Difference: 15 Watts (35%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 220 GDDR3 should perform a small bit faster than the Radeon HD 5570 overall. (explain)

GeForce GT 220 GDDR3		32384 MB/sec
Radeon HD 5570		28800 MB/sec
	Difference: 3584 (12%)

Texel Rate

The Radeon HD 5570 is quite a bit (more or less 30%) faster with regards to texture filtering than the GeForce GT 220 GDDR3. (explain)

Radeon HD 5570		13000 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 3000 (30%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 5570 is a better choice, though only just barely. (explain)

Radeon HD 5570		5200 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 200 (4%)

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 largest amount of data (measured in MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
