GeForce GTX 1630 vs Radeon RX 470

Intro

Compare all of that to the Radeon RX 470, which features a clock frequency of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also features a 256-bit memory bus, and uses a 14 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
Radeon RX 470		120 Watts
	Difference: 45 Watts (60%)

Memory Bandwidth

In theory, the Radeon RX 470 should be 115% faster than the GeForce GTX 1630 in general, because of its higher bandwidth. (explain)

Radeon RX 470		211200 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 112896 (115%)

Texel Rate

The Radeon RX 470 should be a lot (approximately 113%) faster with regards to anisotropic filtering than the GeForce GTX 1630. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 62848 (113%)

Pixel Rate

The Radeon RX 470 is a small bit (more or less 6%) more effective at full screen anti-aliasing than the GeForce GTX 1630, and capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 1792 (6%)

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 megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most 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 ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
