GeForce GTX 1650 vs GeForce GTX 970

Intro

Compare those specifications to the GeForce GTX 970, which has GPU core speed of 1050 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 256-bit bus. It also is comprised of 1664 Stream Processors, 104 TAUs, and 64 ROPs.

	Difference: 70 Watts (93%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 970 is 71% faster than the GeForce GTX 1650 overall, due to its higher data rate. (explain)

GeForce GTX 970		224000 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 92928 (71%)

Texel Rate

The GeForce GTX 970 is quite a bit (about 31%) better at texture filtering than the GeForce GTX 1650. (explain)

GeForce GTX 970		109200 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 26040 (31%)

Pixel Rate

The GeForce GTX 970 is quite a bit (about 41%) better at full screen anti-aliasing than the GeForce GTX 1650, and should be able to handle higher resolutions more effectively. (explain)

GeForce GTX 970		67200 Mpixels/sec
GeForce GTX 1650		47520 Mpixels/sec
	Difference: 19680 (41%)

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 max amount of data (counted in MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units of the card by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
