GeForce GTX 1650 vs GeForce GTX 650

Intro

Compare those specifications to the GeForce GTX 650, which has GPU clock speed of 1058 MHz, and 1024 MB of GDDR5 memory set to run at 1250 MHz through a 128-bit bus. It also is comprised of 384 Stream Processors, 32 TAUs, and 16 Raster Operation Units.

GeForce GTX 650		80000 MB/sec
	Difference: 51072 (64%)

Texel Rate

The GeForce GTX 1650 should be much (about 146%) faster with regards to AF than the GeForce GTX 650. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 49304 (146%)

Pixel Rate

The GeForce GTX 1650 is quite a bit (more or less 181%) faster with regards to anti-aliasing than the GeForce GTX 650, and also will be capable of handling higher screen resolutions better. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 30592 (181%)

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 megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 can be applied per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
