GeForce GTX 1650 vs Radeon RX 6650 XT

Intro

Compare those specifications to the Radeon RX 6650 XT, which comes with a core clock frequency of 2055 MHz and a GDDR6 memory frequency of 2190 MHz. It also makes use of a 128-bit memory bus, and uses a 7 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
Radeon RX 6650 XT		176 Watts
	Difference: 101 Watts (135%)

Memory Bandwidth

In theory, the Radeon RX 6650 XT should be quite a bit faster than the GeForce GTX 1650 in general. (explain)

Radeon RX 6650 XT		287072 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 156000 (119%)

Texel Rate

The Radeon RX 6650 XT will be a lot (approximately 216%) better at texture filtering than the GeForce GTX 1650. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 179880 (216%)

Pixel Rate

The Radeon RX 6650 XT will be much (more or less 177%) better at anti-aliasing than the GeForce GTX 1650, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce GTX 1650		47520 Mpixels/sec
	Difference: 84000 (177%)

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 maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. 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 is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
