Radeon RX 460 vs Radeon RX 550

Intro

The Radeon RX 460 features a GPU core speed of 1090 MHz, and the 4096 MB of GDDR5 memory runs at 1750 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 TAUs, and 16 ROPs.

Compare all that to the Radeon RX 550, which uses a 14 nm design. AMD has set the core frequency at 1100 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this model. It features 512 SPUs as well as 32 Texture Address Units and 16 ROPs.

Memory Bandwidth

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

Radeon RX 550 114688 MB/sec
Radeon RX 460 112000 MB/sec
Difference: 2688 (2%)

Texel Rate

The Radeon RX 460 should be a lot (more or less 73%) better at anisotropic filtering than the Radeon RX 550. (explain)

Radeon RX 460 61040 Mtexels/sec
Radeon RX 550 35200 Mtexels/sec
Difference: 25840 (73%)

Pixel Rate

The Radeon RX 550 should be a small bit (more or less 1%) better at full screen anti-aliasing than the Radeon RX 460, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 550 17600 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 160 (1%)

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 maximum amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses 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 in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 potential to reach the max fill rate.

Hello, can you please tell me which graphics card from amd radeon series rx-460, rx-550 or 560 has the above : resolution at 3840x2160 pixels 60hz, hdr, HDMI v 2.0b HDCP 2.2. I am going to use it on 4k uhdtv hdr mainly for watching movies with mpc-hc
