GeForce GTX 280 vs Radeon RX 550

Intro

The GeForce GTX 280 makes use of a 65 nm design. nVidia has clocked the core speed at 602 MHz. The GDDR3 RAM works at a speed of 1107 MHz on this specific card. It features 240 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.

Compare all of that to the Radeon RX 550, which features core speeds of 1100 MHz on the GPU, and 1750 MHz on the 2048 MB of GDDR5 memory. It features 512 SPUs along with 32 TAUs and 16 ROPs.

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

Pixel Rate

The GeForce GTX 280 will be just a bit (more or less 9%) better at anti-aliasing than the Radeon RX 550, and also will be capable of handling higher screen resolutions without slowing down too much. (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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the 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 the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
