Radeon RX 460 vs Radeon RX 550
Intro
The Radeon RX 460 features clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.Compare all of that to the Radeon RX 550, which makes use of a 14 nm design. AMD has set the core frequency at 1100 MHz. The GDDR5 memory works at a speed of 1750 MHz on this specific card. It features 512 SPUs along with 32 TAUs and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number 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 processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.

3 Responses to “Radeon RX 460 vs Radeon RX 550”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
[…] The Radeon RX 550 will be a small bit (about 1%) faster with regards to anti-aliasing than the Radeon RX 460, and should be capable of handling higher resolutions better. (explain) […]
where is the rx560??
