GeForce GT 220 GDDR3 vs Radeon HD 5830

Intro

The GeForce GT 220 GDDR3 comes with a core clock frequency of 625 MHz and a GDDR3 memory frequency of 1012 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is comprised of 48 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare those specs to the Radeon HD 5830, which comes with a GPU core clock speed of 800 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also features 1120(224x5) SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 220 GDDR3 58 Watts
Radeon HD 5830 175 Watts
Difference: 117 Watts (202%)

Memory Bandwidth

Performance-wise, the Radeon HD 5830 should theoretically be much superior to the GeForce GT 220 GDDR3 in general. (explain)

Radeon HD 5830 128000 MB/sec
GeForce GT 220 GDDR3 32384 MB/sec
Difference: 95616 (295%)

Texel Rate

The Radeon HD 5830 should be quite a bit (more or less 348%) more effective at AF than the GeForce GT 220 GDDR3. (explain)

Radeon HD 5830 44800 Mtexels/sec
GeForce GT 220 GDDR3 10000 Mtexels/sec
Difference: 34800 (348%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 5830 is the winner, and very much so. (explain)

Radeon HD 5830 12800 Mpixels/sec
GeForce GT 220 GDDR3 5000 Mpixels/sec
Difference: 7800 (156%)

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.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core 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 processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
