GeForce GTX 1660 Ti vs GeForce GTX 750 Ti

Intro

Compare those specs to the GeForce GTX 750 Ti, which has GPU clock speed of 1020 MHz, and 2048 MB of GDDR5 RAM set to run at 1350 MHz through a 128-bit bus. It also features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750 Ti		60 Watts
GeForce GTX 1660 Ti		120 Watts
	Difference: 60 Watts (100%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1660 Ti will be 241% faster than the GeForce GTX 750 Ti in general, because of its higher data rate. (explain)

GeForce GTX 1660 Ti		294912 MB/sec
GeForce GTX 750 Ti		86400 MB/sec
	Difference: 208512 (241%)

Texel Rate

The GeForce GTX 1660 Ti should be quite a bit (approximately 253%) better at anisotropic filtering than the GeForce GTX 750 Ti. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
GeForce GTX 750 Ti		40800 Mtexels/sec
	Difference: 103200 (253%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1660 Ti is a better choice, by far. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
GeForce GTX 750 Ti		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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
