GeForce RTX 3050 vs Radeon RX 580

Intro

Compare that to the Radeon RX 580, which features GPU clock speed of 1257 MHz, and 8192 MB of GDDR5 RAM running at 2000 MHz through a 256-bit bus. It also is made up of 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3050		130 Watts
Radeon RX 580		185 Watts
	Difference: 55 Watts (42%)

Memory Bandwidth

In theory, the Radeon RX 580 is 14% faster than the GeForce RTX 3050 in general, due to its higher data rate. (explain)

Radeon RX 580		262144 MB/sec
GeForce RTX 3050		229376 MB/sec
	Difference: 32768 (14%)

Texel Rate

The Radeon RX 580 is a lot (more or less 46%) more effective at AF than the GeForce RTX 3050. (explain)

Radeon RX 580		181008 Mtexels/sec
GeForce RTX 3050		124160 Mtexels/sec
	Difference: 56848 (46%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 3050 is a better choice, by a large margin. (explain)

GeForce RTX 3050		49664 Mpixels/sec
Radeon RX 580		40224 Mpixels/sec
	Difference: 9440 (23%)

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 megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it must 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
