The Evergreen series is a family of GPUs developed by Advanced Micro Devices for its Radeon line under the ATI brand name.

AMD held a press event in the USS Hornet Museum on September 10, 2009[4] and announced ATI Eyefinity multi-display technology and specifications of the Radeon HD 5800 series' variants.

Demand so greatly outweighed supply that more than two months after launch, many online retailers were still having trouble keeping the 5800 and 5900 series in stock.

The on-die display controllers with the new brand name ATI Eyefinity were introduced with the Radeon HD 5000 series.

The Radeon HD 5870 Eyefinity Edition, however, supports six mini DisplayPort outputs, all of which can be simultaneously active.

Unified Video Decoder (UVD2.2)[8] is present on the dies of all products and supported by AMD Catalyst 9.11 and later through DXVA 2.0 on Microsoft Windows and VDPAU on Linux and FreeBSD.

OpenCL accelerates many scientific software packages up to a factor 10 or 100 and more, compared to contemporary CPUs.

[27] The Radeon HD 5900 series utilizes two Cypress graphics processors and a third-party PCI-E bridge.

All reference board designs of the Radeon HD 5500 series are half-height, making them suitable for a low profile form factor chassis.

This may be different for the AMD FirePro brand, which is based on identical hardware but features OpenGL-certified graphics device drivers.
