GeForce GTX 1630 vs Radeon RX 460 2GB

Intro

Compare all of that to the Radeon RX 460 2GB, which has core speeds of 1090 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 memory. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon RX 460 2GB should perform a small bit faster than the GeForce GTX 1630 in general. (explain)

Radeon RX 460 2GB		112000 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 13696 (14%)

Texel Rate

The Radeon RX 460 2GB will be a small bit (more or less 10%) more effective at anisotropic filtering than the GeForce GTX 1630. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 5360 (10%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1630 is the winner, by far. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 10400 (60%)

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 (in units of MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many 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.
