GeForce GTX 1630 vs Radeon RX 580

Intro

Compare all that to the Radeon RX 580, which has a clock speed of 1257 MHz and a GDDR5 memory speed of 2000 MHz. It also features a 256-bit memory bus, and makes use of a 14 nm design. It features 2304 SPUs, 144 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
Radeon RX 580		185 Watts
	Difference: 110 Watts (147%)

Memory Bandwidth

Performance-wise, the Radeon RX 580 should in theory be quite a bit superior to the GeForce GTX 1630 overall. (explain)

Radeon RX 580		262144 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 163840 (167%)

Texel Rate

The Radeon RX 580 will be much (about 225%) more effective at anisotropic filtering than the GeForce GTX 1630. (explain)

Radeon RX 580		181008 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 125328 (225%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 580 is the winner, and very much so. (explain)

Radeon RX 580		40224 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 12384 (44%)

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 information (measured in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
