Radeon HD 4850 1GB vs Radeon HD 5750 512MB

Intro

The Radeon HD 4850 1GB has a GPU core clock speed of 625 MHz, and the 1024 MB of GDDR4 RAM runs at 993 MHz through a 256-bit bus. It also is made up of 800(160x5) Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Compare all of that to the Radeon HD 5750 512MB, which features GPU core speed of 700 MHz, and 512 MB of GDDR5 RAM running at 1150 MHz through a 128-bit bus. It also is made up of 720(144x5) SPUs, 36 Texture Address Units, and 16 ROPs.

Radeon HD 4850 1GB 63552 MB/sec
Difference: 10048 (16%)

Texel Rate

The Radeon HD 5750 512MB should be a small bit (more or less 1%) better at texture filtering than the Radeon HD 4850 1GB. (explain)

Radeon HD 5750 512MB 25200 Mtexels/sec
Radeon HD 4850 1GB 25000 Mtexels/sec
Difference: 200 (1%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 5750 512MB is a better choice, though not by far. (explain)

Radeon HD 5750 512MB 11200 Mpixels/sec
Radeon HD 4850 1GB 10000 Mpixels/sec
Difference: 1200 (12%)

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 data (counted in MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
