[edit] RELEASE DATE

The article mentions R700 is meant to be released for 45nm, in 2009. But right in the begining states that will be out in 2008. Which one is true? Daniel de França (talk) 14:33, 28 January 2008 (UTC)

--may, 2008. The link i provided is to Nordic hardware but its all over the place. Fuds got it, expreviews got it, everyones got it.


[edit] IT IS RELASED !!!!=

Anyone is changing sites ?? this isn't actual state of article.... chipset has been relased (HD RADEON 3870, 3850)... —Preceding unsigned comment added by 83.25.74.8 (talk) 19:32, 6 February 2008 (UTC)

--No, the HD3XX0 series is the R600 family. The R700 chipset is unreleased. —Preceding unsigned comment added by 75.157.29.18 (talk) 07:37, 16 March 2008 (UTC)

[edit] regarding the use of ATI alias

Please note that ATI is no longer a company after the acquision by AMD Inc., instead it's now only a brand name instead of an individual entity.

The people who are doing the Radeon line is now belonged to a group in AMD, the AMD Graphics Product Group.

While it is a subsidiary in nature, the use of ATI alias is now only limited to product branding only. For example, the ATI Radeon Graphics Processors, the ATI CrossFire Xpress 3200 chipset for Intel processors, the ATI XGP Technology, the ATI CrossFire X technology and so on. --203.218.208.248 (talk) 16:04, 8 June 2008 (UTC)
