GeForce GTX 1650 vs Radeon R9 M290X

Intro

Compare all of that to the Radeon R9 M290X, which has GPU core speed of 850 MHz, and 4096 MB of GDDR5 RAM set to run at 1200 MHz through a 256-bit bus. It also is comprised of 1280 Stream Processors, 80 Texture Address Units, and 32 ROPs.

GeForce GTX 1650		75 Watts
Radeon R9 M290X		100 Watts
	Difference: 25 Watts (33%)

Memory Bandwidth

In theory, the Radeon R9 M290X should be 17% faster than the GeForce GTX 1650 overall, because of its greater bandwidth. (explain)

Radeon R9 M290X		153600 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 22528 (17%)

Texel Rate

The GeForce GTX 1650 should be a lot (about 22%) more effective at anisotropic filtering than the Radeon R9 M290X. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon R9 M290X		68000 Mtexels/sec
	Difference: 15160 (22%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1650 is superior to the Radeon R9 M290X, by a large margin. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon R9 M290X		27200 Mpixels/sec
	Difference: 20320 (75%)

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 max amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video 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 amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
