GeForce GTX 1630 vs GeForce GTX 460

Intro

Compare those specifications to the GeForce GTX 460, which makes use of a 40 nm design. nVidia has clocked the core frequency at 675 MHz. The GDDR5 RAM is set to run at a frequency of 900 MHz on this specific model. It features 336 SPUs along with 56 Texture Address Units and 24 ROPs.

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

Texel Rate

The GeForce GTX 1630 should be quite a bit (approximately 47%) more effective 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

The GeForce GTX 1630 should be quite a bit (approximately 72%) better at full screen anti-aliasing than the GeForce GTX 460, and able to handle higher screen resolutions without losing too much performance. (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 MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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.
