GeForce GTX 1630 vs GeForce GTX 460

Intro

Compare that to the GeForce GTX 460, which features a clock speed of 675 MHz and a GDDR5 memory frequency of 900 MHz. It also makes use of a 192-bit memory bus, and uses a 40 nm design. It features 336 SPUs, 56 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The GeForce GTX 1630 should in theory perform just a bit faster 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 (approximately 47%) better at texture filtering than the GeForce GTX 460. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1630 is a better choice, 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 max amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the 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 speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
