GeForce GTX 1650 vs Radeon RX Vega 64

Intro

Compare those specs to the Radeon RX Vega 64, which uses a 14 nm design. AMD has clocked the core speed at 1247 MHz. The HBM2 RAM works at a frequency of 1890 MHz on this specific model. It features 4096 SPUs as well as 256 TAUs and 64 ROPs.

GeForce GTX 1650		83160 Mtexels/sec
	Difference: 236072 (284%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX Vega 64 is the winner, by a large margin. (explain)

Radeon RX Vega 64		79808 Mpixels/sec
GeForce GTX 1650		47520 Mpixels/sec
	Difference: 32288 (68%)

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 (counted in MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
