GeForce GTX 580 3GB vs Radeon RX 5500

Intro

Compare that to the Radeon RX 5500, which makes use of a 7 nm design. AMD has clocked the core speed at 1670 MHz. The GDDR6 memory is set to run at a speed of 1750 MHz on this model. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500		150 Watts
GeForce GTX 580 3GB		244 Watts
	Difference: 94 Watts (63%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5500 will be 19% quicker than the GeForce GTX 580 3GB in general, because of its higher data rate. (explain)

Radeon RX 5500		229376 MB/sec
GeForce GTX 580 3GB		192384 MB/sec
	Difference: 36992 (19%)

Texel Rate

The Radeon RX 5500 is quite a bit (about 197%) more effective at texture filtering than the GeForce GTX 580 3GB. (explain)

Radeon RX 5500		146960 Mtexels/sec
GeForce GTX 580 3GB		49408 Mtexels/sec
	Difference: 97552 (197%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 5500 is a better choice, by far. (explain)

Radeon RX 5500		53440 Mpixels/sec
GeForce GTX 580 3GB		37056 Mpixels/sec
	Difference: 16384 (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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
