GeForce GTX 1650 vs Radeon R9 Nano

Intro

Compare all that to the Radeon R9 Nano, which has a core clock speed of 1000 MHz and a HBM memory speed of 500 MHz. It also uses a 4096-bit bus, and uses a 28 nm design. It is comprised of 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
Radeon R9 Nano		175 Watts
	Difference: 100 Watts (133%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 Nano should be 291% quicker than the GeForce GTX 1650 in general, due to its greater bandwidth. (explain)

Radeon R9 Nano		512000 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 380928 (291%)

Texel Rate

The Radeon R9 Nano should be much (about 208%) more effective at texture filtering than the GeForce GTX 1650. (explain)

Radeon R9 Nano		256000 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 172840 (208%)

Pixel Rate

The Radeon R9 Nano is a lot (about 35%) faster with regards to FSAA than the GeForce GTX 1650, and also will be able to handle higher screen resolutions more effectively. (explain)

Radeon R9 Nano		64000 Mpixels/sec
GeForce GTX 1650		47520 Mpixels/sec
	Difference: 16480 (35%)

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 max amount of data (in units of megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen 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 number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
