GeForce GTX 1650 vs Geforce GTX 680

Intro

The GeForce GTX 1650 has a GPU clock speed of 1485 MHz, and the 4096 MB of GDDR5 memory runs at 2001 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 Texture Address Units, and 32 Raster Operation Units.

Compare those specifications to the Geforce GTX 680, which makes use of a 28 nm design. nVidia has set the core frequency at 1006 MHz. The GDDR5 memory is set to run at a speed of 1502 MHz on this card. It features 1536 SPUs along with 128 TAUs and 32 ROPs.

GeForce GTX 1650 131072 MB/sec
Difference: 61184 (47%)

Texel Rate

The Geforce GTX 680 will be a lot (more or less 55%) more effective at anisotropic filtering than the GeForce GTX 1650. (explain)

Geforce GTX 680 128768 Mtexels/sec
GeForce GTX 1650 83160 Mtexels/sec
Difference: 45608 (55%)

Pixel Rate

The GeForce GTX 1650 is quite a bit (approximately 48%) better at full screen anti-aliasing than the Geforce GTX 680, and also should be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 1650 47520 Mpixels/sec
Geforce GTX 680 32192 Mpixels/sec
Difference: 15328 (48%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at 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 the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
