Radeon HD 4850 2GB vs Radeon HD 5750 1GB

Intro

The Radeon HD 4850 2GB features a GPU core clock speed of 625 MHz, and the 2048 MB of GDDR4 RAM is set to run at 993 MHz through a 256-bit bus. It also is comprised of 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

Compare those specifications to the Radeon HD 5750 1GB, which has GPU clock speed of 700 MHz, and 1024 MB of GDDR5 RAM set to run at 1150 MHz through a 128-bit bus. It also is made up of 720(144x5) SPUs, 36 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5750 1GB 86 Watts
Radeon HD 4850 2GB 110 Watts
Difference: 24 Watts (28%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5750 1GB will be 16% faster than the Radeon HD 4850 2GB overall, due to its higher bandwidth. (explain)

Radeon HD 5750 1GB 73600 MB/sec
Radeon HD 4850 2GB 63552 MB/sec
Difference: 10048 (16%)

Texel Rate

The Radeon HD 5750 1GB should be a bit (more or less 1%) better at AF than the Radeon HD 4850 2GB. (explain)

Radeon HD 5750 1GB 25200 Mtexels/sec
Radeon HD 4850 2GB 25000 Mtexels/sec
Difference: 200 (1%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 5750 1GB is superior to the Radeon HD 4850 2GB, not by a very large margin though. (explain)

Radeon HD 5750 1GB 11200 Mpixels/sec
Radeon HD 4850 2GB 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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
