Texel Rate

The GeForce GTX 1650 will be just a bit (approximately 4%) faster with regards to anisotropic filtering than the Radeon HD 7870. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon HD 7870		80000 Mtexels/sec
	Difference: 3160 (4%)

Pixel Rate

The GeForce GTX 1650 should be a lot (more or less 49%) better at full screen anti-aliasing than the Radeon HD 7870, and also should be capable of handling higher screen resolutions better. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 7870		32000 Mpixels/sec
	Difference: 15520 (49%)

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 information (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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