GeForce GTX 1650 vs GeForce GTX 590

Intro

Compare that to the GeForce GTX 590, which comes with GPU core speed of 607 MHz, and 1536 MB of GDDR5 memory set to run at 855 MHz through a 384-bit bus. It also is made up of 512 Stream Processors, 64 Texture Address Units, and 48 Raster Operation Units.

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

Texel Rate

The GeForce GTX 1650 should be a small bit (about 7%) faster with regards to texture 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 is much (approximately 23%) faster with regards to AA than the GeForce GTX 1650, and will 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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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