GeForce GTX 580 3GB vs Geforce GTX 770

Intro

The GeForce GTX 580 3GB has a core clock speed of 772 MHz and a GDDR5 memory speed of 1002 MHz. It also makes use of a 384-bit memory bus, and uses a 40 nm design. It is comprised of 512 SPUs, 64 TAUs, and 48 ROPs.

Compare those specifications to the Geforce GTX 770, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1046 MHz. The GDDR5 memory works at a frequency of 1753 MHz on this specific model. It features 1536 SPUs as well as 128 Texture Address Units and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
