GeForce GTX 465 vs Radeon RX 550

Intro

The GeForce GTX 465 comes with a GPU clock speed of 607 MHz, and the 1024 MB of GDDR5 memory is set to run at 802 MHz through a 256-bit bus. It also features 352 SPUs, 44 TAUs, and 32 Raster Operation Units.

Compare all of that to the Radeon RX 550, which comes with a core clock frequency of 1100 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit bus, and uses a 14 nm design. It features 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

GeForce GTX 465 102592 MB/sec
Difference: 12096 (12%)

Texel Rate

The Radeon RX 550 will be quite a bit (about 32%) more effective at texture filtering than the GeForce GTX 465. (explain)

Radeon RX 550 35200 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 8492 (32%)

Pixel Rate

The GeForce GTX 465 is just a bit (about 10%) faster with regards to anti-aliasing than the Radeon RX 550, and also will be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 465 19424 Mpixels/sec
Radeon RX 550 17600 Mpixels/sec
Difference: 1824 (10%)

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 largest amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). 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 ability to reach the maximum fill rate.
