Radeon HD 3470 256MB vs Radeon HD 6950

Intro

The Radeon HD 3470 256MB comes with a core clock speed of 800 MHz and a DDR2 memory speed of 950 MHz. It also features a 128-bit memory bus, and makes use of a 55 nm design. It features 40(8x5) SPUs, 4 TAUs, and 4 ROPs.

Compare all that to the Radeon HD 6950, which has GPU clock speed of 800 MHz, and 1024 MB of GDDR5 RAM running at 1250 MHz through a 256-bit bus. It also is made up of 1408 Stream Processors, 88 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 6950 should be 426% quicker than the Radeon HD 3470 256MB in general, because of its greater data rate. (explain)

Radeon HD 6950 160000 MB/sec
Radeon HD 3470 256MB 30400 MB/sec
Difference: 129600 (426%)

Texel Rate

The Radeon HD 6950 should be quite a bit (approximately 2100%) more effective at AF than the Radeon HD 3470 256MB. (explain)

Radeon HD 6950 70400 Mtexels/sec
Radeon HD 3470 256MB 3200 Mtexels/sec
Difference: 67200 (2100%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 6950 is the winner, by a large margin. (explain)

Radeon HD 6950 25600 Mpixels/sec
Radeon HD 3470 256MB 3200 Mpixels/sec
Difference: 22400 (700%)

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 past the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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