GeForce GT 420 vs GeForce GTX 1650

Intro

Compare all of that to the GeForce GTX 1650, which uses a 12 nm design. nVidia has clocked the core frequency at 1485 MHz. The GDDR5 memory works at a speed of 2001 MHz on this specific card. It features 896 SPUs along with 56 TAUs and 32 Rasterization Operator Units.

GeForce GT 420		50 Watts
GeForce GTX 1650		75 Watts
	Difference: 25 Watts (50%)

Memory Bandwidth

In theory, the GeForce GTX 1650 should perform quite a bit faster than the GeForce GT 420 overall. (explain)

GeForce GTX 1650		131072 MB/sec
GeForce GT 420		28800 MB/sec
	Difference: 102272 (355%)

Texel Rate

The GeForce GTX 1650 will be much (about 1385%) faster with regards to anisotropic filtering than the GeForce GT 420. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce GT 420		5600 Mtexels/sec
	Difference: 77560 (1385%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 1650 is superior to the GeForce GT 420, and very much so. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce GT 420		2800 Mpixels/sec
	Difference: 44720 (1597%)

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 data (measured in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
