Texel Rate

The GeForce GTX 1650 is much (more or less 65%) better at AF than the Radeon HD 6870. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon HD 6870		50400 Mtexels/sec
	Difference: 32760 (65%)

Pixel Rate

The GeForce GTX 1650 will be much (approximately 65%) faster with regards to anti-aliasing than the Radeon HD 6870, and also will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 6870		28800 Mpixels/sec
	Difference: 18720 (65%)

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 maximum amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, 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 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
