GeForce GTX 1630 vs Radeon RX 460

Intro

Compare all of that to the Radeon RX 460, which has a core clock speed of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 128-bit bus, and uses a 14 nm design. It is made up of 896 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Radeon RX 460 will be 14% faster than the GeForce GTX 1630 overall, because of its greater data rate. (explain)

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

Texel Rate

The Radeon RX 460 is a small bit (about 10%) better at AF than the GeForce GTX 1630. (explain)

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

Pixel Rate

The GeForce GTX 1630 is a lot (more or less 60%) better at full screen anti-aliasing than the Radeon RX 460, and also will be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 1630		27840 Mpixels/sec
Radeon RX 460		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 maximum amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are 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 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 amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
