GeForce GTX 1630 vs GeForce GTX 460

Intro

Compare those specs to the GeForce GTX 460, which comes with clock speeds of 675 MHz on the GPU, and 900 MHz on the 768 MB of GDDR5 memory. It features 336 SPUs along with 56 Texture Address Units and 24 Rasterization Operator Units.

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

Texel Rate

The GeForce GTX 1630 should be quite a bit (about 47%) faster with regards to anisotropic 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 a high screen resolution is important to you, then the GeForce GTX 1630 is the winner, 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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
