The paper itself, however, has already been published, and I was able to get a copy of it. (Unfortunately, as you'll see at that link, the paper is normally available only to members of the Association for Computing Machinery.)
Peter Glaskowsky是在8月4号去Association for Computing Machinery下载了larrabee的paper后,用了一天的时间来好好分析, 在8月5号得出结论:
而Peter Glaskowsky原意是7-25核心@1G主频的larrabee--相当于2006年的产品vintage Nvidia or Advanced Micro Devices/ATI .
唯一的依据是因为paper里F.E.A.R跑到60帧以上larrabee需要7-25核心@1G主频.
Peter Glaskowsky:But given that limitation of the test procedure, the results don't look very good. To render F.E.A.R. at 60 frames per second--a common definition of good-enough gaming performance--required from 7 to 25 cores, assuming each was running at 1GHz. Although there's a range here depending on the complexity of each frame, good gameplay requires maintaining a high frame rate--so it's possible that F.E.A.R. would, in practice, require at least a 16-core Larrabee processor.And that's about the performance of a 2006-vintage Nvidia or Advanced Micro Devices/ATI graphics chip. This year's chips are three to four times as fast.
----- Peter Glaskowsky为了说明其分析是专业合理的,特地强调一天内看了paper好几次,还有机会与nv/ati的设计师有很多讨论.
I'll be at Siggraph again this year, and I'll have more to say after I've read this paper through a few more times and had a chance to speak with some of the folks I know at AMD, Nvidia, and other companies in the graphics market.
