GeForce GTX 1650		131072 MB/sec
	Difference: 3328 (3%)

Texel Rate

The GeForce GTX 1650 should be quite a bit (approximately 65%) more effective at texture filtering than the Radeon HD 6870. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 1650 is the winner, by a large margin. (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 max amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's 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 can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, 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 most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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.
