Geforce GTX 680 vs Radeon R7 250

Intro

The Geforce GTX 680 comes with a clock frequency of 1006 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It is made up of 1536 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Compare those specs to the Radeon R7 250, which uses a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 memory works at a frequency of 1150 MHz on this specific model. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per 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 - aka 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
