GeForce GTX 1080 vs GeForce GTX 550 Ti

Intro

The GeForce GTX 1080 features clock speeds of 1607 MHz on the GPU, and 1251 MHz on the 8192 MB of GDDR5X RAM. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Compare all that to the GeForce GTX 550 Ti, which makes use of a 40 nm design. nVidia has clocked the core speed at 900 MHz. The GDDR5 memory runs at a speed of 1026 MHz on this particular card. It features 192 SPUs along with 32 Texture Address Units and 24 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 ability to reach the max fill rate.
