GeForce GTX 1650 vs GeForce GTX 660 Ti

Intro

Compare all that to the GeForce GTX 660 Ti, which uses a 28 nm design. nVidia has set the core frequency at 915 MHz. The GDDR5 memory runs at a speed of 1500 MHz on this particular model. It features 1344 SPUs as well as 112 TAUs and 24 ROPs.

The GeForce GTX 660 Ti is much (about 23%) more effective at texture filtering than the GeForce GTX 1650. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 19320 (23%)

Pixel Rate

The GeForce GTX 1650 will be a lot (more or less 116%) faster with regards to full screen anti-aliasing than the GeForce GTX 660 Ti, and also will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 25560 (116%)

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 max amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
