VS

Radeon HD 3470 512MB vs Radeon HD 6750 1GB

Intro

The Radeon HD 3470 512MB has a GPU clock speed of 800 MHz, and the 512 MB of GDDR3 memory is set to run at 950 MHz through a 128-bit bus. It also is comprised of 40(8x5) SPUs, 4 Texture Address Units, and 4 ROPs.

Compare that to the Radeon HD 6750 1GB, which features a clock frequency of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is comprised of 720 SPUs, 36 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 6750 1GB should perform much faster than the Radeon HD 3470 512MB overall. (explain)

Radeon HD 6750 1GB 64000 MB/sec
Radeon HD 3470 512MB 30400 MB/sec
Difference: 33600 (111%)

Texel Rate

The Radeon HD 6750 1GB is quite a bit (more or less 716%) better at AF than the Radeon HD 3470 512MB. (explain)

Radeon HD 6750 1GB 26100 Mtexels/sec
Radeon HD 3470 512MB 3200 Mtexels/sec
Difference: 22900 (716%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 6750 1GB is the winner, and very much so. (explain)

Radeon HD 6750 1GB 11600 Mpixels/sec
Radeon HD 3470 512MB 3200 Mpixels/sec
Difference: 8400 (263%)

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 maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units of the card 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 processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
