Radeon HD 4830 1GB vs Radeon HD 5830

Intro

The Radeon HD 4830 1GB has a clock speed of 575 MHz and a GDDR4 memory speed of 900 MHz. It also makes use of a 256-bit bus, and uses a 55 nm design. It is made up of 640(128x5) SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Compare those specifications to the Radeon HD 5830, which features GPU clock speed of 800 MHz, and 1024 MB of GDDR5 memory set to run at 1000 MHz through a 256-bit bus. It also is comprised of 1120(224x5) Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Radeon HD 5830 128000 MB/sec
Radeon HD 4830 1GB 57600 MB/sec
Difference: 70400 (122%)

Texel Rate

The Radeon HD 5830 should be a lot (more or less 143%) better at anisotropic filtering than the Radeon HD 4830 1GB. (explain)

Radeon HD 5830 44800 Mtexels/sec
Radeon HD 4830 1GB 18400 Mtexels/sec
Difference: 26400 (143%)

Pixel Rate

The Radeon HD 5830 will be a lot (more or less 39%) better at FSAA than the Radeon HD 4830 1GB, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon HD 5830 12800 Mpixels/sec
Radeon HD 4830 1GB 9200 Mpixels/sec
Difference: 3600 (39%)

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 max amount of information (counted in MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
