AMD’s Radeon HD 3850 and HD 3870 will be two of the hottest graphics adaptors for the 2007 holiday season.Â The Radeon HD 3800 series, previously codenamed RV670, is a 55nm optical shrink of the 80nm R600 architecture.
One of the only features added to RV670 is the inclusion of DirectX 10.1 support, an API layer that will be rolled out with Microsoft’s upcoming Windows Vista Service Pack 1.
When asked about the advantages of picking up a DirectX 10 graphics adaptor today, versus waiting for NVIDIA or AMD DirectX 10.1 products, Microsoft’s senior global director of Microsoft games on Windows, Kevin Unangst, replied, “DX10.1 is an incremental update that wonâ€™t affect any games or gamers in the near future.”
Microsoft isn’t the only developer downplaying DirectX 10.1. Cevat Yerli, CEO of Crytek, states,“We pride ourselves on being the first to adopt any important newtechnology that can improve our games so you would expect us to getwith DX10.1 right away but we’ve looked at it and there’s just nothingin it important enough to make it needed.Â So we have no plans to useit at all, not even in the future.”
NVIDIA also has a response for AMD’s DirectX 10.1 support, a feature of AMD’s new HD 3800 series that the company has been rather vocal about.
NVIDIA’s corporate roadmap details plans to include DirectX 10.1 in its ninth-generation GPU architecture, codenamed D9. However, the first D9 processors will not debut until next year, likely after the release of Microsoft’s Vista Service Pack 1.
NVIDIA’s latest guidance describes DirectX 10.1 as “a minor extension of DirectX 10 that makes a few optional features in DirectX 10 mandatory.”
