GeForce GTX 480 vs GeForce GTX 580

Intro

The GeForce GTX 480 comes with core clock speeds of 700 MHz on the GPU, and 924 MHz on the 1536 MB of GDDR5 memory. It features 480 SPUs as well as 60 Texture Address Units and 48 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 580, which makes use of a 40 nm design. nVidia has clocked the core speed at 772 MHz. The GDDR5 memory runs at a frequency of 1002 MHz on this specific card. It features 512 SPUs as well as 64 TAUs and 48 ROPs.

GeForce GTX 480 177408 MB/sec
Difference: 14976 (8%)

Texel Rate

The GeForce GTX 580 is just a bit (more or less 18%) more effective at texture filtering than the GeForce GTX 480. (explain)

GeForce GTX 580 49408 Mtexels/sec
GeForce GTX 480 42000 Mtexels/sec
Difference: 7408 (18%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 580 is a better choice, but not by far. (explain)

GeForce GTX 580 37056 Mpixels/sec
GeForce GTX 480 33600 Mpixels/sec
Difference: 3456 (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: Bandwidth is the max amount of data (measured in MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 are processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.

Difereça quaze nula, é muito mais barata quaze a metade do preço mais barata, concerteza vou de GTX 480 !
