GeForce GTX 470 vs GeForce GTX 580 3GB


Intro

The GeForce GTX 470 features clock speeds of 607 MHz on the GPU, and 837 MHz on the 1280 MB of GDDR5 memory. It features 448 SPUs along with 56 Texture Address Units and 40 ROPs.

Compare that to the GeForce GTX 580 3GB, which comes with GPU core speed of 772 MHz, and 3072 MB of GDDR5 memory running at 1002 MHz through a 384-bit bus. It also is made up of 512 Stream Processors, 64 Texture Address Units, and 48 ROPs.

GeForce GTX 470 133920 MB/sec
Difference: 58464 (44%)

Texel Rate

The GeForce GTX 580 3GB is quite a bit (more or less 45%) more effective at texture filtering than the GeForce GTX 470. (explain)

GeForce GTX 580 3GB 49408 Mtexels/sec
GeForce GTX 470 33992 Mtexels/sec
Difference: 15416 (45%)

Pixel Rate

The GeForce GTX 580 3GB should be a lot (approximately 53%) more effective at FSAA than the GeForce GTX 470, and also able to handle higher resolutions more effectively. (explain)

GeForce GTX 580 3GB 37056 Mpixels/sec
GeForce GTX 470 24280 Mpixels/sec
Difference: 12776 (53%)

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 largest amount of information (in units of MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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.
