Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
Radeon HD 6870		151 Watts
	Difference: 76 Watts (101%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6870 should be 3% quicker than the GeForce GTX 1650 overall, because of its greater bandwidth. (explain)

Radeon HD 6870		134400 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 3328 (3%)

Texel Rate

The GeForce GTX 1650 will be much (about 65%) better 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

The GeForce GTX 1650 is quite a bit (more or less 65%) faster with regards to anti-aliasing than the Radeon HD 6870, and should be capable of handling higher screen resolutions more effectively. (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: Memory bandwidth is the max amount of data (measured in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
