Radeon HD 5750 512MB vs Radeon HD 5830

Intro

The Radeon HD 5750 512MB features a GPU clock speed of 700 MHz, and the 512 MB of GDDR5 RAM is set to run at 1150 MHz through a 128-bit bus. It also features 720(144x5) Stream Processors, 36 Texture Address Units, and 16 ROPs.

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

Radeon HD 5750 512MB 86 Watts
Radeon HD 5830 175 Watts
Difference: 89 Watts (103%)

Memory Bandwidth

Performance-wise, the Radeon HD 5830 should in theory be a lot superior to the Radeon HD 5750 512MB in general. (explain)

Radeon HD 5830 128000 MB/sec
Radeon HD 5750 512MB 73600 MB/sec
Difference: 54400 (74%)

Texel Rate

The Radeon HD 5830 should be quite a bit (about 78%) better at texture filtering than the Radeon HD 5750 512MB. (explain)

Radeon HD 5830 44800 Mtexels/sec
Radeon HD 5750 512MB 25200 Mtexels/sec
Difference: 19600 (78%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 5830 is superior to the Radeon HD 5750 512MB, though not by far. (explain)

Radeon HD 5830 12800 Mpixels/sec
Radeon HD 5750 512MB 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 max amount of information (in units of MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.

I am currently running the XFX Radeon HD 4770 with the AMD Phenom 8400 triple core processor in an MSI 7309 mobo with 4 gigs-(2x2gb) of Corsair PC2-6400 RAM and am playing Call of Duty4 Modern Warfare on max settings and it runs excellent. So my vote goes to the Radeon HD 4770.
