GeForce GT 1030 vs Radeon RX 580

Intro

Compare those specifications to the Radeon RX 580, which uses a 14 nm design. AMD has clocked the core frequency at 1257 MHz. The GDDR5 RAM is set to run at a speed of 2000 MHz on this particular model. It features 2304 SPUs along with 144 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
Radeon RX 580		185 Watts
	Difference: 155 Watts (517%)

Memory Bandwidth

The Radeon RX 580, in theory, should be much faster than the GeForce GT 1030 overall. (explain)

Radeon RX 580		262144 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 212992 (433%)

Texel Rate

The Radeon RX 580 is quite a bit (more or less 347%) more effective at AF than the GeForce GT 1030. (explain)

Radeon RX 580		181008 Mtexels/sec
GeForce GT 1030		40480 Mtexels/sec
	Difference: 140528 (347%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 580 is superior to the GeForce GT 1030, and very much so. (explain)

Radeon RX 580		40224 Mpixels/sec
GeForce GT 1030		20240 Mpixels/sec
	Difference: 19984 (99%)

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 max amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to 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 potential to reach the max fill rate.
