GeForce GTX 1660 Ti vs GeForce GTX 750

Intro

Compare all of that to the GeForce GTX 750, which has a clock frequency of 1020 MHz and a GDDR5 memory frequency of 1250 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It features 512 SPUs, 32 TAUs, and 16 ROPs.

GeForce GTX 750		32640 Mtexels/sec
	Difference: 111360 (341%)

Pixel Rate

The GeForce GTX 1660 Ti should be quite a bit (approximately 341%) faster with regards to AA than the GeForce GTX 750, and capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
GeForce GTX 750		16320 Mpixels/sec
	Difference: 55680 (341%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at 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 that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate 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 filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
