About the AMD Radeon RX 455 (OEM) GPU

The AMD Radeon RX 455 (OEM) is an end-of-life desktop graphics card that released in Q2 2016. It is built on the GCN 2.0 GPU microarchitecture (codename Tobago) and is manufactured on a 28 nm process.

Memory

The RX 455 has 2 GB of GDDR5 memory, with a 1,625 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 104 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 RX 455 includes 768 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,050 MHz. Complementing the processing units are 48 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The RX 455 is a compact, low-profile graphics card that fits into 1 PCIe expansion slot. It supports DVI, HDMI 1.4a, DisplayPort 1.2 display connections. AMD recommends a power supply of at least 300 W to handle the GPU's thermal design power (TDP) of 100 W.
