主题：【IT动态】在64位 Linux 平台上，Intel和AMD那个更出色 -- Highway
刚刚看到一篇很有意思的评测，就是在64位Linux平台上，让AMD和Intel的最新64 位CPU直接“过招”，看看那个系统更为优秀。同时，为了参照，两种平台还都安装了32位的Linux。这样通过测试大家不仅仅可以对AMD和Intel这两种系统的性能有个横向的比较，同时还可以看出从32位移植到64位，系统是不是有什么大的性能上的提高。
测试的过程请参看 外链出处， 这里简单公布一下结果
[SIZE=3]Conclusions[/SIZE]
In conclusion to all I've presented here, I want to talk about the value of these processors. When speaking about value, we can get bogged down in a lot of speculation about what's it worth to you versus how much money you have to spend on such things, etc. We're going to keep this on the level of, “what are you getting for your money with these processors?” First, when you look at my benchmarking results above, you'll see that the Pentium 4 only had two strong suits, it can encode video and it can run certain workstation graphics applications. Whether Intel processors for your Linux box makes sense, will depend on what percentage of the time you do either of these tasks. For the majority of people that say they do more of the other tasks presented here, Athlon 64 processors are really your only options. The Pentium 4 in most applications just does not have enough performance versus the competition. If you look at value, AMD gives you more performance, at the same price point, in more applications. It will also be easier to cool it using less expensive cooling methods and save you on energy costs. Looking at the two AMD options presented here, we see that you'll pay a premium for the top processor. This is normal, as you always pay a premium for the best. The Athlon 64 FX line does offer a large benefit though if you're an enthusiast interested in overclocking. The processor is multiplier unlocked which will give you greater flexibility when pushing the system to its max. I'll finish up with giving Intel a little credit. (I'm a positive guy by nature.) They do continue to add to their processors and try to improve them. This is being done not only through clock speed increases but also other features such as cache sizes and energy saving features such as Speedstep. This keeps their processors interesting and makes them valuable as a competitor to AMD.
[B]Right now, it just seems that AMD has a superior architecture and that Intel is going to have to make a pretty significant change to pass AMD in performance. The only thing that's on radar to heat things up a bit is dual-core processors. First to market with available chips and a solid platform will have a solid lead until the other company's chips surface. I'll keep on it and once I see it, you'll hear about it.[/B]
现在multi-core也要再次现窘了。根据今天arstechnica.com的一篇文章，AMD的Opteron从一开始就为multi-core做了准备，对AMD来说，什么时候推出multi-core只是一句话，“等市场”。Intel则麻烦大了，不仅要从头开始，还得解决Prescott的散热问题。为了保住老大的颜面，Intel只好匆匆忙忙地作弊，把两个处理器打包在一起，也号称是multi-core（VIA就曾经这么干过一回，被人嘲笑了一把）。
当然，Intel还是有杀手锏的。Pentium M的效率至今无人能企及。
老兄讲的：Pentium M的效率至今无人能企及
是不说速度呢？都到这时候了，单机内存都有1G、2G的了，心脏的速度差一点又有什么关系呢？
但是好像I对WIN的支持好点。以前在用166/MMX200时候是这感觉。现在没有感觉了。
BTW：谁能帮我写个英文的或是日文的认罪书？承认我用了D版XP，我叫二狗子。剩下咋写都中。
Prescott的末日早就订下，现在只是维持局面而以。今后多内核的CPU，也都是现在PM的展开....
昨天，在Intel的Forum上，它已经展示了65nm制程的下一代multi-core CPU。可见在芯片制造技术上Intel比AMD还是领先不少的。AMD现在90nm的制程还没有完全掌握，Wafer还是200mm的，和Intel差距至少一年以上。
现在Intel的CPU虽然结构上有些问题，但通过加大Cache，提升Memory bus speed，还是和AMD不相上下的。
现在AMD还处在盈利/亏损边缘，有多少后劲还不好说！
双重障碍让竞争者很难取得短期以外的优势.
如果Intel的P4可以在32bit保持领先，A64就不会有那么大的市场，Itanium就是还有希望的。毕竟大家用的大部分软件还是32bit的。但是A64在32bit运行中领先，又可以轻松过渡到64bit，这才是问题的关键。
Intel改变自己一贯的backward compatibility策略，其成功的一个必要条件就是在32bit保持领先。毕竟Intel过于轻视AMD了。
不是计算，而是寻址空间。
三十年的领头羊，现在居然要跟在了AMD的后面。
同意Highway的说法，相比于Intel，AMD还只能算是大象脚边的一只狐狸（比老鼠还是要大一些）。
不仅Intel三十年来积攒的家底还仍然非常厚实，老格鲁夫给Intel留下的教条更是使整个公司上下都时刻保持着危机感。
大象不过是在路上打了个趔趄。
重要了。
是继承了P3的衣钵。如果这是真的，那Intel那帮负责P4的工程师们可丢脸丢大发了。
