Radeon HD 4830 512MB vs Radeon HD 5670

Intro

The Radeon HD 4830 512MB comes with clock speeds of 575 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 640(128x5) SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Compare those specs to the Radeon HD 5670, which makes use of a 40 nm design. AMD has clocked the core speed at 775 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this model. It features 400(80x5) SPUs as well as 20 Texture Address Units and 8 ROPs.

Radeon HD 5670 64000 MB/sec
Radeon HD 4830 512MB 57600 MB/sec
Difference: 6400 (11%)

Texel Rate

The Radeon HD 4830 512MB should be a little bit (approximately 19%) more effective at anisotropic filtering than the Radeon HD 5670. (explain)

Radeon HD 4830 512MB 18400 Mtexels/sec
Radeon HD 5670 15500 Mtexels/sec
Difference: 2900 (19%)

Pixel Rate

The Radeon HD 4830 512MB should be much (more or less 48%) more effective at AA than the Radeon HD 5670, and also will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon HD 4830 512MB 9200 Mpixels/sec
Radeon HD 5670 6200 Mpixels/sec
Difference: 3000 (48%)

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 information (in units of MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
