GeForce GT 220 GDDR3 vs Radeon HD 5570

Intro

The GeForce GT 220 GDDR3 has a clock speed of 625 MHz and a GDDR3 memory frequency of 1012 MHz. It also features a 128-bit memory bus, and uses a 40 nm design. It features 48 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare those specs to the Radeon HD 5570, which has core clock speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of DDR3 RAM. It features 400(80x5) SPUs along with 20 Texture Address Units and 8 ROPs.

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

In theory, the GeForce GT 220 GDDR3 should perform a bit faster than the Radeon HD 5570 in general. (explain)

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

Texel Rate

The Radeon HD 5570 should be a lot (about 30%) better at anisotropic 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 using a high screen resolution is important to you, then the Radeon HD 5570 is the winner, though not by far. (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.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

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