Radeon HD 5750 1GB vs Radeon HD 5830

Intro

The Radeon HD 5750 1GB has core speeds of 700 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 memory. It features 720(144x5) SPUs as well as 36 TAUs and 16 ROPs.

Compare all of that to the Radeon HD 5830, which uses a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM 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.

Texel Rate

The Radeon HD 5830 is much (about 78%) faster with regards to anisotropic filtering than the Radeon HD 5750 1GB. (explain)

Radeon HD 5830 44800 Mtexels/sec
Radeon HD 5750 1GB 25200 Mtexels/sec
Difference: 19600 (78%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 5830 is the winner, but only just. (explain)

Radeon HD 5830 12800 Mpixels/sec
Radeon HD 5750 1GB 11200 Mpixels/sec
Difference: 1600 (14%)

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 (counted in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 high 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 texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record 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 clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
