AMD's Radeon HD family finally here after seven months of empty release dates.

Well for those of you eagerly awaiting AMD's release of their ATI Radeon HD family of graphics cards, the wait is finally over.

The new ATI Radeon HD 2000 family consists of the HD 2400, HD 2600 and HD 2900 graphics processors, formerly known as RV610, RV630 and R600, respectively. Although AMD will announce its ATI Radeon HD 2000 series, only the ATI Radeon HD 2900 XT will have immediate availability. The accompanying ATI Radeon HD 2400 and HD 2600-based products are paper launches.

Further, according to the source, Radeon HD2900 XT (formerly known as R600) will also be available to purchase from today onwards. However the XTX version of the card has been delayed further and as such will not be available to retail channels for the moment... Possibly due to it's lack-lustre performance of which we brought to your attention a short while ago.

Taking on NVIDIA’s recently launched GeForce 8600 family is the new ATI Radeon HD 2600 series. AMD plans to paper launch the ATI Radeon HD 2600 in PRO and XT guises. The ATI Radeon HD 2600 series features 120 stream processors. The GPU is clocked anywhere between 600 to 800 MHz depending on flavor. AMD backs the 120 stream processors with eight texture units and four render backends.

The amount of processing power brings the ATI Radeon HD 2600 GPU transistor count to 390 million. Nevertheless, the ATI Radeon HD 2600 is manufactured on a 65nm process. AMD rates power consumption at approximately 45 watts.

At the bottom of the new ATI Radeon 2000-series lineup is the ATI Radeon HD 2400 series with PRO and XT models. The new ATI Radeon HD 2400 features 40 stream processors with four texture units and render backends. GPU clocks vary between 525 MHz to 700 MHz.

The ATI Radeon HD 2400 series features less than half the transistors as the HD 2600 – 180 million. AMD has the ATI Radeon HD 2400 series manufactured on the same 65nm process as the HD 2600. Power consumption of the ATI Radeon HD 2400 hovers around 25 watts.

Add-in board manufacturers are free to equip ATI Radeon HD 2400 series graphics cards with GDDR3 or DDR2 memory. The GPU supports 128MB or 256MB memory configurations on a 64-bit memory interface. Memory clock can vary from 800 MHz to 1.6 GHz depending on model. Expect ATI Radeon HD 2400 series graphics cards to support HDMI audio and video output via a DVI to HDMI adapter.

Even though the cards have officially launched, the HD 2900 XT will be the only card that is actually available. Both the Radeon HD 2600 and 2400 versions of the card should be available for retail in late June 2007.

Expect to pay $399 for an ATI Radeon HD 2900 XT tomorrow from the usual add-in board partners including Diamond Multimedia, HIS, PowerColor and Sapphire Technology. AMD expects to target the ATI Radeon HD 2600 series towards the $99 to $199 market segment and ATI Radeon HD 2400 series towards the less than $99 segment.
