Radeon HD 5670 vs Radeon HD 5750 1GB

Intro

The Radeon HD 5670 uses a 40 nm design. AMD has set the core frequency at 775 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this particular model. It features 400(80x5) SPUs along with 20 TAUs and 8 ROPs.

Compare those specifications to the Radeon HD 5750 1GB, which comes with GPU core speed of 700 MHz, and 1024 MB of GDDR5 memory running at 1150 MHz through a 128-bit bus. It also features 720(144x5) SPUs, 36 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5670 61 Watts
Radeon HD 5750 1GB 86 Watts
Difference: 25 Watts (41%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5750 1GB will be 15% quicker than the Radeon HD 5670 overall, because of its higher data rate. (explain)

Radeon HD 5750 1GB 73600 MB/sec
Radeon HD 5670 64000 MB/sec
Difference: 9600 (15%)

Texel Rate

The Radeon HD 5750 1GB should be quite a bit (more or less 63%) faster with regards to texture filtering than the Radeon HD 5670. (explain)

Radeon HD 5750 1GB 25200 Mtexels/sec
Radeon HD 5670 15500 Mtexels/sec
Difference: 9700 (63%)

Pixel Rate

The Radeon HD 5750 1GB should be much (approximately 81%) better at AA than the Radeon HD 5670, and able to handle higher resolutions more effectively. (explain)

Radeon HD 5750 1GB 11200 Mpixels/sec
Radeon HD 5670 6200 Mpixels/sec
Difference: 5000 (81%)

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 data (measured in megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
