ATI's HD 6000 series was meant to be manufactured at 32nm
 

At AMD's Technical Forum and Exhibition 2010, we had a quick chat with Matt Skynner, Corporate VP and General Manager of AMD's GPU Division, about the decision to continue using TSMC's 40nm process for ATI's Radeon HD 6000 series. We asked if these new graphics cards launched too early, instead of late this year/next year when TSMC's 28nm process was ready.

Mr Skynner admitted that the HD 6000 series was originally set to use TSMC's 32nm process, but that AMD had to opt back to 40nm earlier this year after that process was unceremoniously dumped by TSMC in favour of concentrating on 28nm only. Excluding the yield issues with the more recent 40nm process, TSMC does have great experience in creating high performance, low power half-node processes suitable for GPUs at 110nm, 80nm and 55nm, and this is where 28nm looks to continue.
