GeForce GTX 1650 vs GeForce GTX 590

Intro

Compare those specs to the GeForce GTX 590, which uses a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 RAM works at a speed of 855 MHz on this card. It features 512 SPUs as well as 64 Texture Address Units and 48 ROPs.

GeForce GTX 1650		75 Watts
GeForce GTX 590		365 Watts
	Difference: 290 Watts (387%)

Memory Bandwidth

Performance-wise, the GeForce GTX 590 should theoretically be much superior to the GeForce GTX 1650 overall. (explain)

GeForce GTX 590		328320 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 197248 (150%)

Texel Rate

The GeForce GTX 1650 is just a bit (approximately 7%) faster with regards to anisotropic filtering than the GeForce GTX 590. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce GTX 590		77696 Mtexels/sec
	Difference: 5464 (7%)

Pixel Rate

The GeForce GTX 590 should be much (more or less 23%) better at FSAA than the GeForce GTX 1650, and also should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 590		58272 Mpixels/sec
GeForce GTX 1650		47520 Mpixels/sec
	Difference: 10752 (23%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 per second. This figure is worked out 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 applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
