GeForce GTX 275 vs Radeon R7 260X

Intro

The GeForce GTX 275 uses a 55 nm design. nVidia has clocked the core speed at 633 MHz. The GDDR3 memory works at a frequency of 1134 MHz on this specific card. It features 240 SPUs as well as 80 Texture Address Units and 28 Rasterization Operator Units.

Compare those specifications to the Radeon R7 260X, which comes with GPU clock speed of 1100 MHz, and 2048 MB of GDDR5 memory set to run at 1625 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 TAUs, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
