GeForce GTX 1630 vs Geforce GTX 780

Intro

Compare those specifications to the Geforce GTX 780, which features a core clock speed of 863 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 384-bit memory bus, and makes use of a 28 nm design. It is made up of 2304 SPUs, 192 TAUs, and 48 Raster Operation Units.

GeForce GTX 1630		75 Watts
Geforce GTX 780		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

Theoretically, the Geforce GTX 780 should be quite a bit faster than the GeForce GTX 1630 overall. (explain)

Geforce GTX 780		288384 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 190080 (193%)

Texel Rate

The Geforce GTX 780 is much (more or less 198%) faster with regards to AF than the GeForce GTX 1630. (explain)

Geforce GTX 780		165696 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 110016 (198%)

Pixel Rate

If running with a high screen resolution is important to you, then the Geforce GTX 780 is a better choice, by far. (explain)

Geforce GTX 780		41424 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 13584 (49%)

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 max amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount 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 fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
