GeForce GTX 1630 vs GeForce GTX 460

Intro

Compare those specs to the GeForce GTX 460, which has GPU clock speed of 675 MHz, and 768 MB of GDDR5 memory set to run at 900 MHz through a 192-bit bus. It also is made up of 336 SPUs, 56 TAUs, and 24 Raster Operation Units.

GeForce GTX 1630		75 Watts
GeForce GTX 460		150 Watts
	Difference: 75 Watts (100%)

Memory Bandwidth

Performance-wise, the GeForce GTX 1630 should theoretically be a little bit better than the GeForce GTX 460 in general. (explain)

GeForce GTX 1630		98304 MB/sec
GeForce GTX 460		86400 MB/sec
	Difference: 11904 (14%)

Texel Rate

The GeForce GTX 1630 is quite a bit (about 47%) better at AF than the GeForce GTX 460. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 17880 (47%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 1630 is superior to the GeForce GTX 460, and very much so. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTX 460		16200 Mpixels/sec
	Difference: 11640 (72%)

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 data (in units of megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its 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 the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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.
