GeForce GTX 1630 vs Radeon RX 460 2GB

Intro

Compare all of that to the Radeon RX 460 2GB, which features a clock frequency of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 128-bit memory bus, and uses a 14 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon RX 460 2GB is 14% faster than the GeForce GTX 1630 overall, because of its greater data rate. (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 little bit (more or less 10%) more effective at AF than the GeForce GTX 1630. (explain)

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

Pixel Rate

The GeForce GTX 1630 should be much (approximately 60%) more effective at full screen anti-aliasing than the Radeon RX 460 2GB, and also should be able to handle higher resolutions more effectively. (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 data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
