Geforce GTX 770 vs Radeon R7 240

Intro

The Geforce GTX 770 has a GPU core speed of 1046 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1753 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.

Compare that to the Radeon R7 240, which comes with GPU clock speed of 730 MHz, and 2048 MB of DDR3 memory running at 900 MHz through a 128-bit bus. It also features 320 SPUs, 20 TAUs, and 8 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
