GeForce GTX 1650 vs GeForce GTX 660

Intro

Compare all of that to the GeForce GTX 660, which has a core clock speed of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 192-bit bus, and uses a 28 nm design. It is comprised of 960 SPUs, 80 Texture Address Units, and 24 ROPs.

The GeForce GTX 1650 is a bit (approximately 6%) more effective at AF than the GeForce GTX 660. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce GTX 660		78400 Mtexels/sec
	Difference: 4760 (6%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 1650 is superior to the GeForce GTX 660, by a large margin. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce GTX 660		23520 Mpixels/sec
	Difference: 24000 (102%)

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 data (in units of MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
