ATI Radeon HD 4700

The ATI Radeon HD 4700 is an end-of-life desktop graphics card that released in Q1 2010. It is built on the TeraScale GPU microarchitecture (codename RV730) and is manufactured on a 55 nm process.

Memory

The HD 4700 has 512 MB of DDR2 memory, with a 400 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 12.8 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 4700 includes 320 shading units, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 600 MHz. Complementing the processing units are 32 texture mapping units (TMUs) for efficient texture filtering and 8 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The HD 4700 is a compact, low-profile graphics card that fits into 1 PCIe expansion slot. It supports DVI, S-Video display connections. ATI recommends a power supply of at least 250 W to handle the GPU's thermal design power (TDP) of 50 W.
