GeForce GTX 1630 vs Radeon R9 380 2G

Intro

Compare all that to the Radeon R9 380 2G, which makes use of a 28 nm design. AMD has set the core speed at 970 MHz. The GDDR5 RAM runs at a frequency of 1425 MHz on this card. It features 1792 SPUs along with 112 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
Radeon R9 380 2G		190 Watts
	Difference: 115 Watts (153%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 380 2G is 86% faster than the GeForce GTX 1630 overall, due to its greater data rate. (explain)

Radeon R9 380 2G		182400 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 84096 (86%)

Texel Rate

The Radeon R9 380 2G will be quite a bit (approximately 95%) better at anisotropic filtering than the GeForce GTX 1630. (explain)

Radeon R9 380 2G		108640 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 52960 (95%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 380 2G is superior to the GeForce GTX 1630, but only just. (explain)

Radeon R9 380 2G		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 largest amount of data (in units of MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the 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 texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better 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 amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number 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 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 - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
