GeForce GTX 570 vs Radeon HD 3470 256MB

Intro

The GeForce GTX 570 has core speeds of 732 MHz on the GPU, and 950 MHz on the 1280 MB of GDDR5 memory. It features 480 SPUs along with 60 TAUs and 40 ROPs.

Compare that to the Radeon HD 3470 256MB, which comes with a GPU core clock speed of 800 MHz, and 256 MB of DDR2 RAM running at 950 MHz through a 128-bit bus. It also features 40(8x5) SPUs, 4 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 570 should theoretically perform quite a bit faster than the Radeon HD 3470 256MB overall. (explain)

GeForce GTX 570 152000 MB/sec
Radeon HD 3470 256MB 30400 MB/sec
Difference: 121600 (400%)

Texel Rate

The GeForce GTX 570 should be a lot (about 1273%) better at texture filtering than the Radeon HD 3470 256MB. (explain)

GeForce GTX 570 43920 Mtexels/sec
Radeon HD 3470 256MB 3200 Mtexels/sec
Difference: 40720 (1273%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 570 is the winner, and very much so. (explain)

GeForce GTX 570 29280 Mpixels/sec
Radeon HD 3470 256MB 3200 Mpixels/sec
Difference: 26080 (815%)

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 MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This 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 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 card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
