GeForce GTX 1650 vs Radeon RX Vega 56

Intro

Compare all of that to the Radeon RX Vega 56, which comes with a core clock frequency of 1156 MHz and a HBM2 memory speed of 1600 MHz. It also makes use of a 2048-bit memory bus, and makes use of a 14 nm design. It is made up of 3584 SPUs, 224 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
Radeon RX Vega 56		210 Watts
	Difference: 135 Watts (180%)

Memory Bandwidth

In theory, the Radeon RX Vega 56 should be 220% faster than the GeForce GTX 1650 in general, due to its higher data rate. (explain)

Radeon RX Vega 56		419430 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 288358 (220%)

Texel Rate

The Radeon RX Vega 56 should be a lot (approximately 211%) more effective at anisotropic filtering than the GeForce GTX 1650. (explain)

Radeon RX Vega 56		258944 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 175784 (211%)

Pixel Rate

The Radeon RX Vega 56 should be much (about 56%) faster with regards to anti-aliasing than the GeForce GTX 1650, and also should be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX Vega 56		73984 Mpixels/sec
GeForce GTX 1650		47520 Mpixels/sec
	Difference: 26464 (56%)

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 largest amount of information (measured in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 can be processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video 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 most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
