Radeon HD 5750 1GB vs Radeon HD 5830

Intro

The Radeon HD 5750 1GB makes use of a 40 nm design. AMD has set the core speed at 700 MHz. The GDDR5 RAM works at a speed of 1150 MHz on this particular card. It features 720(144x5) SPUs as well as 36 TAUs and 16 ROPs.

Compare that to the Radeon HD 5830, which has core speeds of 800 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 1120(224x5) SPUs along with 56 TAUs and 16 ROPs.

Radeon HD 5750 1GB 73600 MB/sec
Difference: 54400 (74%)

Texel Rate

The Radeon HD 5830 should be much (more or less 78%) more effective at texture 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

The Radeon HD 5830 will be just a bit (about 14%) more effective at AA than the Radeon HD 5750 1GB, and also capable of handling higher screen resolutions more effectively. (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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 are processed in one second. This is calculated by multiplying the total texture units of the card by the core 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 processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
