GeForce GTX 580 vs Radeon RX 5500

Intro

The GeForce GTX 580 comes with core speeds of 772 MHz on the GPU, and 1002 MHz on the 1536 MB of GDDR5 memory. It features 512 SPUs along with 64 Texture Address Units and 48 ROPs.

Compare all that to the Radeon RX 5500, which features GPU core speed of 1670 MHz, and 4096 MB of GDDR6 memory set to run at 1750 MHz through a 128-bit bus. It also is comprised of 1408 Stream Processors, 88 TAUs, and 32 Raster Operation Units.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better 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 most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
