GeForce GTX 1650 vs Radeon R9 M390X

Intro

Compare all of that to the Radeon R9 M390X, which features a core clock speed of 723 MHz and a GDDR5 memory frequency of 1250 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

GeForce GTX 1650		131072 MB/sec
	Difference: 28928 (22%)

Texel Rate

The Radeon R9 M390X should be a small bit (more or less 11%) more effective at anisotropic filtering than the GeForce GTX 1650. (explain)

Radeon R9 M390X		92544 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 9384 (11%)

Pixel Rate

The GeForce GTX 1650 will be much (about 105%) better at FSAA than the Radeon R9 M390X, and should be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon R9 M390X		23136 Mpixels/sec
	Difference: 24384 (105%)

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 information (measured in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
