GeForce GTX 1650 vs GeForce GTX 660

Intro

Compare that to the GeForce GTX 660, which uses a 28 nm design. nVidia has set the core frequency at 980 MHz. The GDDR5 memory works at a frequency of 1502 MHz on this particular card. It features 960 SPUs along with 80 Texture Address Units and 24 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
GeForce GTX 660		140 Watts
	Difference: 65 Watts (87%)

Memory Bandwidth

Theoretically, the GeForce GTX 660 should be a bit faster than the GeForce GTX 1650 overall. (explain)

GeForce GTX 660		144192 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 13120 (10%)

Texel Rate

The GeForce GTX 1650 will be just a bit (more or less 6%) better at texture filtering than the GeForce GTX 660. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 1650 is a better choice, by far. (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: Bandwidth is the max amount of information (in units of megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record 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 core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
