GeForce GTX 580 vs Radeon HD 7970
Intro
The GeForce GTX 580 features a core clock frequency of 772 MHz and a GDDR5 memory speed of 1002 MHz. It also uses a 384-bit memory bus, and makes use of a 40 nm design. It features 512 SPUs, 64 Texture Address Units, and 48 ROPs.Compare those specifications to the Radeon HD 7970, which comes with clock speeds of 925 MHz on the GPU, and 1375 MHz on the 3072 MB of GDDR5 memory. It features 2048 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units 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 processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.

3 Responses to “GeForce GTX 580 vs Radeon HD 7970”hmmm it seems hd770 won in memory bus and texel rate but the 580 won the pixel rate, but who is the best among them?
yes the 7970 is the winner, because of its 140% win over the 580 in the texel rate
AMD 7970 absolutely more fast than 580, but they still can't handle physx engine in some way they been kicked by Nvidia 2010 card technology.
it depend on your gaming needs and specification.
in this case (hi-end gaming) i am still in the "GREEN" side. they are fast as well.
but for my brothers PC i chose AMD beast gaming machine for the mid-end gaming.
