Texel Rate

The GeForce GTX 1650 will be quite a bit (more or less 120%) faster with regards to AF than the GeForce GTX 460. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 45360 (120%)

Pixel Rate

The GeForce GTX 1650 is much (more or less 193%) faster with regards to anti-aliasing than the GeForce GTX 460, and will be capable of handling higher screen resolutions better. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce GTX 460		16200 Mpixels/sec
	Difference: 31320 (193%)

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 (measured in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant 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.
