GeForce GTX 1650 vs Geforce GTX 780

Intro

Compare all of that to the Geforce GTX 780, which features a clock speed of 863 MHz and a GDDR5 memory speed of 1502 MHz. It also makes use of a 384-bit memory bus, and uses a 28 nm design. It is comprised of 2304 SPUs, 192 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
Geforce GTX 780		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

The Geforce GTX 780, in theory, should perform much faster than the GeForce GTX 1650 in general. (explain)

Geforce GTX 780		288384 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 157312 (120%)

Texel Rate

The Geforce GTX 780 should be a lot (more or less 99%) more effective at AF than the GeForce GTX 1650. (explain)

Geforce GTX 780		165696 Mtexels/sec
GeForce GTX 1650		83160 Mtexels/sec
	Difference: 82536 (99%)

Pixel Rate

The GeForce GTX 1650 is just a bit (more or less 15%) better at AA than the Geforce GTX 780, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Geforce GTX 780		41424 Mpixels/sec
	Difference: 6096 (15%)

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 transferred across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics 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 most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
