GeForce GTX 280 vs Radeon RX 550

Intro

The GeForce GTX 280 features a GPU core clock speed of 602 MHz, and the 1024 MB of GDDR3 RAM runs at 1107 MHz through a 512-bit bus. It also features 240 SPUs, 80 TAUs, and 32 ROPs.

Compare those specifications to the Radeon RX 550, which uses a 14 nm design. AMD has set the core frequency at 1100 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this specific card. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Radeon RX 550 114688 MB/sec
Difference: 27008 (24%)

Texel Rate

The GeForce GTX 280 should be a lot (more or less 37%) faster with regards to texture filtering than the Radeon RX 550. (explain)

GeForce GTX 280 48160 Mtexels/sec
Radeon RX 550 35200 Mtexels/sec
Difference: 12960 (37%)

Pixel Rate

The GeForce GTX 280 is a small bit (more or less 9%) faster with regards to FSAA than the Radeon RX 550, and also should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 280 19264 Mpixels/sec
Radeon RX 550 17600 Mpixels/sec
Difference: 1664 (9%)

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: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It's calculated 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 ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
