GeForce GTX 1080 vs GeForce GTX 550 Ti

Intro

The GeForce GTX 1080 has a clock frequency of 1607 MHz and a GDDR5X memory frequency of 1251 MHz. It also features a 256-bit memory bus, and uses a 16 nm design. It is comprised of 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Compare those specifications to the GeForce GTX 550 Ti, which makes use of a 40 nm design. nVidia has set the core frequency 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 TAUs and 24 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
