GeForce GTX 1630 vs Radeon R9 380X

Intro

Compare those specifications to the Radeon R9 380X, which makes use of a 28 nm design. AMD has set the core speed at 970 MHz. The GDDR5 RAM works at a speed of 1425 MHz on this particular card. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

GeForce GTX 1630		75 Watts
Radeon R9 380X		190 Watts
	Difference: 115 Watts (153%)

Memory Bandwidth

In theory, the Radeon R9 380X will be 86% faster than the GeForce GTX 1630 overall, due to its higher bandwidth. (explain)

Radeon R9 380X		182400 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 84096 (86%)

Texel Rate

The Radeon R9 380X will be a lot (approximately 123%) better at AF than the GeForce GTX 1630. (explain)

Radeon R9 380X		124160 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 68480 (123%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 380X is a better choice, though only just barely. (explain)

Radeon R9 380X		31040 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 3200 (11%)

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 maximum amount of data (counted in MB per second) that can be transported across the external memory interface in a second. It's calculated 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 ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
