The Evergreen series is a family of GPUs

line under the ATI
brand name.
museum on September 10, 2009 and announced ATI Eyefinity multi-display technology and specifications of the Radeon HD 5800 series' variants. The first variants of the Radeon HD 5800 series were launched September 23, 2009, with the HD 5700 series launching October 12 and HD 5970 launching on November 18 The HD 5670, was launched on January 14, 2010, and the HD 5500 and 5400 series were launched in February 2010, completing what has appeared to be most of AMD's Evergreen GPU lineup.
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.
Recently, the 5xxx series has been popular to those generating Bitcoins, due to its large number of stream processors

11 capabilities with new instructions. Also similar to RV770, four texture units are tied to 16 stream cores (each have five processing elements, making a total of 80 processing elements). This combination of is referred to as a SIMD core.
Unlike the predecessor
, as DirectX 11 mandates full developer control over interpolation so dedicated interpolators were removed, relying instead on the SIMD cores. The stream cores can handle the higher rounding precision fused multiply–add (FMA) instruction in both single and double precision which increases precision over multiply–add (MAD) and is compliant to IEEE 754-2008 standard. The instruction sum of absolute differences
(SAD) has been natively added to the processors. This instruction can be used to greatly improve the performance of some processes, such as video encoding and transcoding. Each SIMD core is equipped with 32 kiB local data share and 8 kiB of L1 cache, while all SIMD cores share 64 kiB global data share.
The entire HD 5000 series products have Eyefinity capabilities supporting three outputs. The Radeon HD 5870 Eyefinity Edition, however, supports six mini DisplayPort
outputs, all of which can be simultaneously active.
The display unit on Evergreen family of GPUs was completely replaced with one that has two DACs
which are used to drive the DVI
ports in analog mode (for example, when a DVI to VGA converter attached to a DVI port), a maximum of six digital transmitters that can output either a DisplayPort
signal or a TMDS
signal which is used for either DVI or HDMI
, and two clock signal
generators needed to drive the digital outputs in TMDS mode. Dual-link DVI displays use two of the TMDS/DisplayPort transmitters and one clock signal each. Single-link DVI displays and HDMI displays use one TMDS/DisplayPort transmitter and one clock signal each. DisplayPort displays use one TMDS/DisplayPort transmitter and no clock signal.
A DisplayPort adapter or dongle can be used to convert a DisplayPort signal to another type of signal like VGA, single or dual link DVI, or HDMI if more than two non-DisplayPort displays need to be connected to a Radeon HD 5000 series graphics card. The table below shows the maximum possible configurations on a normal Radeon HD 5800/5700 series add-in card.
However, other configurations are possible while not being explicitly detailed or verified by AMD (e.g., DVI, HDMI, and VGA).

On Evergreen family GPUs, DisplayPort outputs on board are capable of 10-bit per component output, and HDMI
output is capable of 12-bit per component output.

. The 5770 series has a 128-bit bus width, as opposed to the 5800 series, which has a 256-bit bus width. Performance-wise, the 5770 is comparable to last-generation's Radeon 4870.
All reference board designs of the Radeon HD 5500 series are half-height, making them suitable for a low profile form factor chassis.

AMD also introduced AMD Eyefinity Technology (previously ATI Eyefinity) in this GPU family - the ability to connect three to six displays to one graphics card. It also supports grouping of multiple monitors into a single large surface (SLS), treated by the OS as a single monitor with very high resolutions. It is promoted as an inexpensive alternative for ultra-high resolution displays.The entire HD 5000 series products have Eyefinity capabilities supporting three outputs.

Radeon HD 5900
Codenamed Hemlock, the Radeon HD 5900 series was announced on October 12, 2009, starting with the HD 5970. The Radeon HD 5900 series utilizes two Cypress graphics processors and a third-party PCI-E bridge, similar to Radeon HD 4800 X2 series graphics cards; however, AMD has abandoned the use of X2 moniker for dual-GPU variants starting with Radeon HD 5900 series, making it the only series within the Evergreen GPU family to have two GPUs on one PCB.Radeon HD 5800
Codenamed Cypress, the Radeon HD 5800 series was announced on September 23, 2009. Products included Radeon HD 5850 and Radeon HD 5870. The launching model of Radeon HD 5870 can support three display outputs at most. In terms of overall performance, the 5870 comes in between the GTX 470 and GTX 480 from rival company Nvidia, being closer to the GTX 480 than the GTX 470. An Eyefinity 6 edition of Radeon HD 5870 was released, with 2 GB GDDR5 memory, supporting six simultaneous displays to be connected to the mini DisplayPort outputs. The Radeon HD 5870 has 1600 usable stream cores, while the Radeon HD 5850 has 1,440 usable stream cores, as 160 out of the 1,600 total cores are disabled during product binningProduct binning

Radeon HD 5600
Codenamed Redwood XT, the Radeon HD 5670 was released on January 14, 2010. The Radeon HD 5670 has 400 stream cores and a core clock of 775 MHz with 1,000 MHz (4.0 Gbit/s) GDDR5 memory.Radeon HD 5500
Codenamed Redwood PRO and Redwood LE, the Radeon HD 5570 was released on February 9, 2010. It uses the same GPU as the Radeon HD 5670 but has a lower core frequency, at first release was limited to DDR3 memory, but later, ATI added support for GDDR5 memory. One more variant, with only 320 stream cores, is available and Radeon HD 5550 was suggested as the product name. Some Radeon HD 5550 cards have GDDR5 memory too.All reference board designs of the Radeon HD 5500 series are half-height, making them suitable for a low profile form factor chassis.
Radeon HD 5400
Codenamed Cedar, the Radeon HD 5400 series was announced on February 4, 2010, starting with the HD 5450. The Radeon HD 5450 has 80 stream cores, a core clock of 650 MHz, and 800 MHz DDR2 or DDR3 memory. The 5400 series is designed to assume a low-profile card size.Chipset table
