Radeon HD 3650 256MB vs Radeon HD 5830

Intro

The Radeon HD 3650 256MB uses a 55 nm design. AMD has clocked the core frequency at 725 MHz. The DDR2 memory runs at a frequency of 800 MHz on this particular card. It features 120(24x5) SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Compare all that to the Radeon HD 5830, which comes with a core clock speed of 800 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It features 1120(224x5) SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Radeon HD 5830 128000 MB/sec
Radeon HD 3650 256MB 25600 MB/sec
Difference: 102400 (400%)

Texel Rate

The Radeon HD 5830 is quite a bit (about 672%) more effective at anisotropic filtering than the Radeon HD 3650 256MB. (explain)

Radeon HD 5830 44800 Mtexels/sec
Radeon HD 3650 256MB 5800 Mtexels/sec
Difference: 39000 (672%)

Pixel Rate

The Radeon HD 5830 should be quite a bit (about 341%) better at AA than the Radeon HD 3650 256MB, and should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon HD 5830 12800 Mpixels/sec
Radeon HD 3650 256MB 2900 Mpixels/sec
Difference: 9900 (341%)

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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the 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 maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
