GeForce GTX 1660 Ti vs Radeon HD 7750

Intro

Compare those specifications to the Radeon HD 7750, which comes with GPU core speed of 800 MHz, and 1024 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is comprised of 512 Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

Radeon HD 7750		55 Watts
GeForce GTX 1660 Ti		120 Watts
	Difference: 65 Watts (118%)

Memory Bandwidth

In theory, the GeForce GTX 1660 Ti will be 310% quicker than the Radeon HD 7750 overall, due to its greater bandwidth. (explain)

GeForce GTX 1660 Ti		294912 MB/sec
Radeon HD 7750		72000 MB/sec
	Difference: 222912 (310%)

Texel Rate

The GeForce GTX 1660 Ti is a lot (more or less 463%) more effective at texture filtering than the Radeon HD 7750. (explain)

GeForce GTX 1660 Ti		144000 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 118400 (463%)

Pixel Rate

The GeForce GTX 1660 Ti should be much (more or less 463%) better at anti-aliasing than the Radeon HD 7750, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1660 Ti		72000 Mpixels/sec
Radeon HD 7750		12800 Mpixels/sec
	Difference: 59200 (463%)

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 largest amount of information (counted in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 are applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, 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 most pixels the video card could possibly record to the local memory in a 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 - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
