AMD Radeon 550X (Mobile)

The AMD Radeon 550X (Mobile) is an end-of-life mobile graphics card that released in Q2 2018. It is built on the GCN 4.0 GPU microarchitecture (codename Polaris 23) and is manufactured on a 14 nm process.

Memory

The 550X has 2 GB of GDDR5 memory, with a 1,000 MHz memory clock and a 64 bit interface. This gives it a memory bandwidth of 32 Gb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.

Cores and Clock Speeds

The 550X includes 640 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,082 MHz. Complementing the processing units are 40 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 50 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
