Popular Turkish website Donanimhaber has released an expected schedule for the release of ATI’s Radeon HD 6000 series. The first HD 6000 GPU to be released will be the Radeon HD 6700 series, codenamed Barts. The HD 6700 is scheduled for a release as early as October. As suggested by the nomenclature, the HD 6700 will directly replace the HD 5700 series.

The HD 6700 release will be followed up by Cayman in November, expected to be branded as the ATI Radeon HD 6800 series, replacing the current HD 5800 series.

Popular Turkish website Donanimhaber has released an expected schedule
for the release of ATI’s Radeon HD 6000 series. The first HD 6000 GPU to
be released will be the Radeon HD 6700 series, codenamed Barts. The HD
6700 is scheduled for a release as early as October. As suggested by the
nomenclature, the HD 6700 will directly replace the HD 5700 series.

The HD 6700 release will be followed up by Cayman in November, expected
to be branded as the ATI Radeon HD 6800 series, replacing the current HD
5800 series.

The flagship will be Antilles, and branded as the ATI Radeon HD 6970. Antilles, as expected, will be a dual-GPU Cayman. While the HD 5970 lowers clock speeds from the HD 5870, HD 6970 is expected to feature the same clock speeds as the HD 6870 – basically a HD 6870 in CF. This will be much like the HD 4870 X2. The Radeon HD 6970 is scheduled for December.

The Catalyst 10.8 Codename leaks supports much of Donanimhaber’s schedule. Cayman and Antilles come under the same sub-family, and it is likely that Cayman is HD 6800 and Antilles is dual-Cayman – HD 6900. Barts could very well be HD 6700 series as well. Interestingly, all three, Cayman, Antilles and Barts are West Indian Islands. The other two from the codenames list being Turks and Caicos. If the HD 6000 series follows the pattern of the HD 5000 series, we could very well have two further chips to replace Redwood and Cedar. These could very well be Turks and Caicos, releasing in Q1 2011. However, this leaves us with several unused codenames from the Catalyst
10.8 list. It could be that the list covers more than the HD 6000
series.

Traditionally, the x8xx product has always been the first to release. Releasing with the HD 6700 series can be a novelty. However, AMD have experimented with a x7xx card before. The first 40nm GPU was the HD 4770 – part of the otherwise 55nm HD 4000 generation.

An Antilles PRO is listed in the codenames – and we could have a Radeon HD 6950 GPU. However, this depends largely on the requirements. A Radeon HD 5950 – Hemlock Pro – was rumoured as well, but was never released due to a lack of competition. The suggestion that the HD 6970 will feature the same clock speeds as the HD 6870 has two implications. First, a larger performance gap between the HD 6870 and HD 6970 for the HD 6950 to fit in. More importantly, the HD 6800 series could have a lower TDP than the HD 5800 series, in which case Efficiency could be one of the key objectives of the HD 6000 family.

It has been a long, long time since AMD released a GPU (not counting minor upgrades such as the HD 5500 GDDR5 versions). It is fair to assume that they have been hard at work, and the lull is about to be broken by a storm of HD 6000 releases in Q4 2010 and Q1 2011.
