At the Microprocessor Forum, Intel demoed its V8 workstation running the POV-Ray benchmark. The machine is equipped with Intel's Workstation Board S5000XVN, 2 quad-core Xeons 5365, clocked at 3GHz and 16GB RAM. And the results are simply impressive: Intel scored over 4,900 pixels per seconds versus a little bit over 4,000 for AMD's 4 sockets quad-core (Barcelona) system. Again, this is an AMD 16 cores system versus Intel's 8 cores V8 machine.
If you take 16 cores at 1.8Ghz, divided by 2 and add 60% to get to 3.0Ghz, it gives POV-Ray score of 3600 for 8 cores. Meaning that at 3.0GHz, Barcelona still lose by quite some compare to an 8 cores Clowertown system.
在微处理器论坛,intel展示了它的v8工作站运行pov-ray测试的情况。
测试机器采用了intel的工作站主板S5000XVN,两个3G的四核心至强5365和16GB的内存。并且结果也是让人影响深刻:intel以约4900像素/秒的扥风超过了AMD的4插槽16核心(巴塞罗那)系统的4000像素/秒。再一次,AMD16核心和intel 8核心对比。
如果 6个核心运行在1.8G,去掉两个核心并增加60%的频率来达到3G,8个核心的巴塞罗那POV-Ray 成绩应该在3600像素/秒左右。那么在3g,巴塞罗那仍然以相当多的幅度输给了8核心clovertown系统作者: qiumd 时间: 2007-5-27 17:59

"Why do you need 16 cores, when you can do better with 8. Our 8 core system is 30% faster than the 16 core machine AMD showed to the press yesterday. I just don't understand how they can claim to be 40% faster", said Francois Piednoel, an Intel engineer present at the show.
Well, now AMD has some explanation to do and sooner rather than later. Because if they can't figure out what happened with those POV-Ray results they showed us, that's the end of it. At the show, Intel also demoed a system with a 45nm Penryn quad-core processor (shipping by year end, about the same time than Barcelona!) that is 40% faster than the top of the line quad-core generation, the Core 2 Extreme processor QX6800. Wow!
