GeForce GTX 1660 Ti vs GeForce GTX 560 Ti 448

Intro

The GeForce GTX 1660 Ti comes with clock speeds of 1500 MHz on the GPU, and 1500 MHz on the 6144 MB of GDDR6 memory. It features 1536 SPUs along with 96 Texture Address Units and 48 ROPs.

Compare all that to the GeForce GTX 560 Ti 448, which has GPU clock speed of 732 MHz, and 1280 MB of GDDR5 RAM set to run at 900 MHz through a 320-bit bus. It also is made up of 448 Stream Processors, 56 TAUs, and 40 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
