GeForce GTX 1650 vs Radeon R9 380 2G

Intro

Compare all of that to the Radeon R9 380 2G, which comes with GPU core speed of 970 MHz, and 2048 MB of GDDR5 RAM running at 1425 MHz through a 256-bit bus. It also is made up of 1792 SPUs, 112 TAUs, and 32 ROPs.

GeForce GTX 1650		75 Watts
Radeon R9 380 2G		190 Watts
	Difference: 115 Watts (153%)

Memory Bandwidth

In theory, the Radeon R9 380 2G will be 39% faster than the GeForce GTX 1650 in general, because of its higher data rate. (explain)

Radeon R9 380 2G		182400 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 51328 (39%)

Texel Rate

The Radeon R9 380 2G is quite a bit (about 31%) better at texture filtering than the GeForce GTX 1650. (explain)

Radeon R9 380 2G		108640 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 25480 (31%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 1650 is a better choice, and very much so. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon R9 380 2G		31040 Mpixels/sec
	Difference: 16480 (53%)

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 information (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the 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 texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
