GeForce GTX 1650 vs GeForce GTX 580

Intro

Compare all that to the GeForce GTX 580, which features a GPU core clock speed of 772 MHz, and 1536 MB of GDDR5 RAM set to run at 1002 MHz through a 384-bit bus. It also is comprised of 512 Stream Processors, 64 TAUs, and 48 ROPs.

GeForce GTX 1650		75 Watts
GeForce GTX 580		244 Watts
	Difference: 169 Watts (225%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 580 is 47% faster than the GeForce GTX 1650 in general, due to its higher data rate. (explain)

GeForce GTX 580		192384 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 61312 (47%)

Texel Rate

The GeForce GTX 1650 is much (approximately 68%) better at AF than the GeForce GTX 580. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce GTX 580		49408 Mtexels/sec
	Difference: 33752 (68%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1650 is superior to the GeForce GTX 580, and very much so. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce GTX 580		37056 Mpixels/sec
	Difference: 10464 (28%)

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: Bandwidth is the maximum amount of information (in units of MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number 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 applied in a second.

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