GeForce GTX 550 Ti vs Radeon R9 M280X

Intro

The GeForce GTX 550 Ti uses a 40 nm design. nVidia has clocked the core speed at 900 MHz. The GDDR5 memory is set to run at a frequency of 1026 MHz on this particular model. It features 192 SPUs along with 32 Texture Address Units and 24 Rasterization Operator Units.

Compare all of that to the Radeon R9 M280X, which uses a 28 nm design. AMD has set the core frequency at 900 MHz. The GDDR5 RAM runs at a frequency of 1375 MHz on this card. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
