GeForce GTX 285 1GB vs Radeon RX 550

Intro

Compare those specifications to the Radeon RX 550, which has GPU clock speed of 1100 MHz, and 2048 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also is made up of 512 Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

Radeon RX 550		114688 MB/sec
	Difference: 44288 (39%)

Texel Rate

The GeForce GTX 285 1GB is a lot (more or less 47%) faster with regards to AF than the Radeon RX 550. (explain)

GeForce GTX 285 1GB		51840 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 16640 (47%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 285 1GB is superior to the Radeon RX 550, though only just barely. (explain)

Radeon RX 550		17600 Mpixels/sec
	Difference: 3136 (18%)

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 data (measured in MB per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 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 texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, 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 most pixels that the graphics chip could 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 Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
