GeForce GTX 550 Ti vs Radeon RX 550

Intro

The GeForce GTX 550 Ti features a GPU core clock speed of 900 MHz, and the 1024 MB of GDDR5 memory runs at 1026 MHz through a 192-bit bus. It also is comprised of 192 Stream Processors, 32 Texture Address Units, and 24 ROPs.

Compare those specifications to the Radeon RX 550, which makes use of a 14 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this particular card. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

GeForce GTX 550 Ti 98496 MB/sec
Difference: 16192 (16%)

Texel Rate

The Radeon RX 550 should be a lot (approximately 22%) more effective at AF than the GeForce GTX 550 Ti. (explain)

Radeon RX 550 35200 Mtexels/sec
GeForce GTX 550 Ti 28800 Mtexels/sec
Difference: 6400 (22%)

Pixel Rate

The GeForce GTX 550 Ti will be a lot (about 23%) more effective at full screen anti-aliasing than the Radeon RX 550, and will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 550 Ti 21600 Mpixels/sec
Radeon RX 550 17600 Mpixels/sec
Difference: 4000 (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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling 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 card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
