GeForce GTX 580 vs Radeon HD 6770 1GB
Intro
The GeForce GTX 580 comes with core clock speeds of 772 MHz on the GPU, and 1002 MHz on the 1536 MB of GDDR5 memory. It features 512 SPUs along with 64 TAUs and 48 ROPs.Compare those specifications to the Radeon HD 6770 1GB, which features a clock speed of 900 MHz and a GDDR5 memory speed of 1050 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 800 SPUs, 40 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.

One Response to “GeForce GTX 580 vs Radeon HD 6770 1GB”I went from my old GTX 470 to GTX 580 cause of power for perfomance and temperature...
In games is much faster and renders about 120% Times faster and also about 40-50% faster than GTX 680!!!!
