GeForce GTX 1650		131072 MB/sec
Radeon HD 4650 1GB		22400 MB/sec
	Difference: 108672 (485%)

Texel Rate

The GeForce GTX 1650 should be quite a bit (more or less 333%) faster with regards to AF than the Radeon HD 4650 1GB. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon HD 4650 1GB		19200 Mtexels/sec
	Difference: 63960 (333%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1650 is superior to the Radeon HD 4650 1GB, by a large margin. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 4650 1GB		4800 Mpixels/sec
	Difference: 42720 (890%)

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 largest amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. It's 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 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 are applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write 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 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 quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
