GeForce GTX 580 3GB vs Radeon R7 240

Intro

The GeForce GTX 580 3GB comes with a GPU core clock speed of 772 MHz, and the 3072 MB of GDDR5 RAM is set to run at 1002 MHz through a 384-bit bus. It also is comprised of 512 Stream Processors, 64 TAUs, and 48 Raster Operation Units.

Compare all of that to the Radeon R7 240, which comes with core speeds of 730 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 320 SPUs as well as 20 Texture Address Units and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
