GeForce GTX 1630 vs GeForce GTX 560

Intro

Compare those specs to the GeForce GTX 560, which has a GPU core clock speed of 810 MHz, and 1024 MB of GDDR5 RAM running at 1001 MHz through a 256-bit bus. It also is comprised of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.

GeForce GTX 1630		98304 MB/sec
	Difference: 29824 (30%)

Texel Rate

The GeForce GTX 1630 is quite a bit (approximately 23%) faster with regards to texture filtering than the GeForce GTX 560. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTX 560		45360 Mtexels/sec
	Difference: 10320 (23%)

Pixel Rate

The GeForce GTX 1630 should be just a bit (approximately 7%) more effective at FSAA than the GeForce GTX 560, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTX 560		25920 Mpixels/sec
	Difference: 1920 (7%)

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 transported past the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
