家园 【评论】64位对64位,Opteron -- Xeon Nocona

[SIZE=4]AMD Opteron 150 vs. Intel Xeon 3.6 Nocona[/SIZE]

对于Unix高端用户来说,64位那已经是十多年前的遥远的事了。但是对于广大的PC用户而言,这一高不可攀的东西今天才似乎变得伸手可及。虽然Intel的Itanium问世已有多年了,但那玩意要求全新的软件来支持,所以一直没有被主流市场认可。

PC界的64位革命是从AMD的Athlon 64和Opteron才真正开始的。AMD的64位平台不仅可以运行现有的所有32位PC软件,更可以运行下一代的64位X86软件。Intel起初藐视这一行动,但后来感到这可能是大势所趋,所以也着急忙慌的挤了进来,推出了自己的32/64位处理器。

虽然微软的64位操作系统到明年才能Ready(XP 64 bit Edition/Windows 2003 Server 64 bit Edition),但是64位的Linux早已等候多时了。今天的擂台赛就是在64位Linux平台上,由AMD的Opteron 150 对阵Intel的Xeon 3.6 Nocona。

总评:

First of all, AMD's Opteron 150 is the highest performing AMD workstation CPU money can buy. Thus, it is priced around $600 at time of publication. (The nearly identical FX-53 is priced slightly higher). Intel's Xeon 3.6GHz / Pentium 4 3.6F processor is the highest performing Intel workstation CPU money can't buy; although it has shown up in various OEM channels, it really has not hit the market in full force yet. When it does, we are expected to see it retail for $850. This automatically raises the question as to whether or not these two are directly competing processors. Since prices in the market fluctuate daily depending on vendor stock with such high end CPUs, we leave that decision up to the reader.

Secondly, GCC 3.3.3 optimizations became a larger than expected variable in these tests. As shown in the TSCP benchmark, changing the optimization flags wildly changed performance of the Opteron CPU, while the Nocona only received mild benefits. We also hear that GCC 3.4 tends to increase performance on the Opteron CPUs even further, although we ran out of time to complete that test.

After all is said and done it became difficult (nearly impossible?) to justify the Xeon processor in a UP configuration over the Opteron 150, but perhaps we will see significant changes in dual and four way configurations. We have Linux benchmark shootout between the two processors coming up, as well as a Windows analysis too.

一。只要Windows没有正式进入64位市场,个人用户就不会真正进入这个市场段,而任何不能够玩主流游戏的平台都不可能成为个人用户的主流平台。

二。Linux可能有这样那样的优点,但是在64位服务器领域,目前它所需要对付是自己的前辈Unix及其硬件,而不是Windows。因此AMD/Intel的芯片需要和Risc芯片争夺高端性能。

三。我很怀疑用MySQL这类业余数据库做评测有何意义,至少应该用Sybase,如果不是Oracle的话。专业软件是建立在专利和投入上的,而不仅仅是工作热情,MySQL如果能够在功能上击败Oracle,Oracle和IBM都应该倒闭了。
