Radeon HD 4350 vs Radeon HD 5830

Intro

The Radeon HD 4350 has core clock speeds of 575 MHz on the GPU, and 500 MHz on the 512 MB of DDR2 RAM. It features 80(16x5) SPUs along with 8 Texture Address Units and 4 ROPs.

Compare all of that to the Radeon HD 5830, which makes use of a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory works at a speed of 1000 MHz on this particular card. It features 1120(224x5) SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

Radeon HD 4350 22 Watts
Radeon HD 5830 175 Watts
Difference: 153 Watts (695%)

Memory Bandwidth

The Radeon HD 5830 should in theory perform much faster than the Radeon HD 4350 overall. (explain)

Radeon HD 5830 128000 MB/sec
Radeon HD 4350 8000 MB/sec
Difference: 120000 (1500%)

Texel Rate

The Radeon HD 5830 will be quite a bit (about 874%) better at AF than the Radeon HD 4350. (explain)

Radeon HD 5830 44800 Mtexels/sec
Radeon HD 4350 4600 Mtexels/sec
Difference: 40200 (874%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 5830 is a better choice, by far. (explain)

Radeon HD 5830 12800 Mpixels/sec
Radeon HD 4350 2300 Mpixels/sec
Difference: 10500 (457%)

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 (counted in megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
