GeForce GTX 1650 vs GeForce GTX 570

Intro

Compare all that to the GeForce GTX 570, which comes with a GPU core clock speed of 732 MHz, and 1280 MB of GDDR5 RAM set to run at 950 MHz through a 320-bit bus. It also is made up of 480 Stream Processors, 60 Texture Address Units, and 40 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
GeForce GTX 570		219 Watts
	Difference: 144 Watts (192%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 570 will be 16% faster than the GeForce GTX 1650 in general, due to its greater bandwidth. (explain)

GeForce GTX 570		152000 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 20928 (16%)

Texel Rate

The GeForce GTX 1650 is quite a bit (approximately 89%) more effective at AF than the GeForce GTX 570. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce GTX 570		43920 Mtexels/sec
	Difference: 39240 (89%)

Pixel Rate

The GeForce GTX 1650 will be a lot (more or less 62%) faster with regards to AA than the GeForce GTX 570, and will be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce GTX 570		29280 Mpixels/sec
	Difference: 18240 (62%)

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 largest amount of information (counted in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 potential to get to the max fill rate.
