Radeon HD 3470 512MB vs Radeon HD 3650 256MB

Intro

The Radeon HD 3470 512MB uses a 55 nm design. AMD has set the core frequency at 800 MHz. The GDDR3 RAM is set to run at a frequency of 950 MHz on this specific model. It features 40(8x5) SPUs as well as 4 Texture Address Units and 4 Rasterization Operator Units.

Compare all of that to the Radeon HD 3650 256MB, which has GPU clock speed of 725 MHz, and 256 MB of DDR2 memory set to run at 800 MHz through a 128-bit bus. It also features 120(24x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon HD 3470 512MB should perform a little bit faster than the Radeon HD 3650 256MB in general. (explain)

Radeon HD 3470 512MB 30400 MB/sec
Radeon HD 3650 256MB 25600 MB/sec
Difference: 4800 (19%)

Texel Rate

The Radeon HD 3650 256MB should be quite a bit (about 81%) faster with regards to AF than the Radeon HD 3470 512MB. (explain)

Radeon HD 3650 256MB 5800 Mtexels/sec
Radeon HD 3470 512MB 3200 Mtexels/sec
Difference: 2600 (81%)

Pixel Rate

If using a high resolution is important to you, then the Radeon HD 3470 512MB is superior to the Radeon HD 3650 256MB, though not by far. (explain)

Radeon HD 3470 512MB 3200 Mpixels/sec
Radeon HD 3650 256MB 2900 Mpixels/sec
Difference: 300 (10%)

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 data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card 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 colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
