GeForce GTX 1630 vs Radeon RX 470

Intro

Compare that to the Radeon RX 470, which makes use of a 14 nm design. AMD has clocked the core speed at 926 MHz. The GDDR5 memory runs at a speed of 1650 MHz on this particular model. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

	Difference: 45 Watts (60%)

Memory Bandwidth

The Radeon RX 470 should in theory be a lot faster than the GeForce GTX 1630 in general. (explain)

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

Texel Rate

The Radeon RX 470 is much (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 should be a bit (about 6%) better at AA than the GeForce GTX 1630, and also able to handle higher screen resolutions without losing too much performance. (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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at 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 its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
