Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
Radeon HD 6970		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

In theory, the Radeon HD 6970 should be 34% quicker than the GeForce GTX 1650 overall, because of its greater data rate. (explain)

Radeon HD 6970		176000 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 44928 (34%)

Texel Rate

The Radeon HD 6970 is a bit (about 2%) better at anisotropic filtering than the GeForce GTX 1650. (explain)

Radeon HD 6970		84480 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 1320 (2%)

Pixel Rate

If running with high levels of AA 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 6970		28160 Mpixels/sec
	Difference: 19360 (69%)

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 (in units of megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
