GeForce GTX 1630		75 Watts
GeForce GTX 970		145 Watts
	Difference: 70 Watts (93%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 970 should be 128% quicker than the GeForce GTX 1630 overall, because of its higher data rate. (explain)

GeForce GTX 970		224000 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 125696 (128%)

Texel Rate

The GeForce GTX 970 will be quite a bit (approximately 96%) faster with regards to AF than the GeForce GTX 1630. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 970 is the winner, 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: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

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