GeForce GTX 1630 vs GeForce GTX 970

Intro

Compare those specifications to the GeForce GTX 970, which features a core clock frequency of 1050 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 256-bit memory bus, and makes use of a 28 nm design. It features 1664 SPUs, 104 Texture Address Units, and 64 ROPs.

GeForce GTX 1630		98304 MB/sec
	Difference: 125696 (128%)

Texel Rate

The GeForce GTX 970 should be a lot (more or less 96%) faster with regards to texture filtering than the GeForce GTX 1630. (explain)

GeForce GTX 970		109200 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 53520 (96%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 970 is a better choice, by far. (explain)

GeForce GTX 970		67200 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 39360 (141%)

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 largest amount of data (measured in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video 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 amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
