Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
Radeon R9 270X		180 Watts
	Difference: 105 Watts (140%)

Memory Bandwidth

In theory, the Radeon R9 270X should be 82% faster than the GeForce GTX 1630 in general, due to its greater data rate. (explain)

Radeon R9 270X		179200 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 80896 (82%)

Texel Rate

The Radeon R9 270X is a lot (about 44%) better at AF than the GeForce GTX 1630. (explain)

Radeon R9 270X		80000 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 24320 (44%)

Pixel Rate

The Radeon R9 270X should be a bit (more or less 15%) more effective at anti-aliasing than the GeForce GTX 1630, and also will be able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 270X		32000 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 4160 (15%)

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 (measured in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 can be processed in one second. This is worked out by multiplying the total number of texture units by the core clock 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
