AMD Radeon HD 8770 (OEM)

The AMD Radeon HD 8770 (OEM) is an end-of-life desktop graphics card that released in Q3 2013. It is built on the GCN 2.0 GPU microarchitecture (codename Bonaire) and is manufactured on a 28 nm process.

Memory

The HD 8770 has 1,024 MB of GDDR5 memory, with a 1,500 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 96 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 HD 8770 includes 896 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 56 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The HD 8770 occupies 2 PCIe expansion slots. It supports DVI, HDMI 1.4a, mini-DisplayPort 1.2 display connections. AMD recommends a power supply of at least 250 W to handle the GPU's thermal design power (TDP) of 85 W.
