GeForce GTX 460 2GB vs Radeon RX 550

Intro

The GeForce GTX 460 2GB uses a 40 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR5 RAM is set to run at a speed of 900 MHz on this particular card. It features 336 SPUs along with 56 TAUs and 32 Rasterization Operator Units.

Compare all of that to the Radeon RX 550, which has a clock speed of 1100 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit memory bus, and uses a 14 nm design. It is made up of 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550 50 Watts
GeForce GTX 460 2GB 160 Watts
Difference: 110 Watts (220%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 2GB should be a little bit faster than the Radeon RX 550 in general. (explain)

GeForce GTX 460 2GB 115200 MB/sec
Radeon RX 550 114688 MB/sec
Difference: 512 (0%)

Texel Rate

The GeForce GTX 460 2GB should be just a bit (about 7%) faster with regards to texture filtering than the Radeon RX 550. (explain)

GeForce GTX 460 2GB 37800 Mtexels/sec
Radeon RX 550 35200 Mtexels/sec
Difference: 2600 (7%)

Pixel Rate

The GeForce GTX 460 2GB should be much (more or less 23%) more effective at anti-aliasing than the Radeon RX 550, and also will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 460 2GB 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: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 are processed per second. This figure is calculated by multiplying the total texture units of the card 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock 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 rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
