千万别买双核电脑
 

两年前我买了一个P4 2.66的电脑；最近买了一个所谓的双核1.66，发现速度比我两年前的p4慢多了，真TMD的上当

千万不要买所谓的双核而牺牲主频，宁可买p4的高频或者p5（有没有奔5？）

cpu生产商搞不出更高的速度，就玩双核低频的概念，上当了，所以告诫向我一样不懂电脑的朋友：

宁可奔4，不要赶所谓时髦买双核:rolleyes1:

没觉得, 你的是Core dual 还是Core 2 dual?

有区别吗？不都是双核？

现在好点的大多都是双核了把. 除非自己攒机.

AMD Athlon 64 X2 4200 （刚买的） 对比 Intel P4 3.0 （三年前买的） 来用 Super PI 计算比较结果，P4 3.0 的速度明显快。

不管说得多好听，使用的感觉总是最真的：看来hardywang这样的专家也证明了我的看法

二级缓存容量分别一个为4MB, 一个为2MB。

双核针对多任务会快一些，单任务没有优势。

that's right

Hey guys you can't evaluate a system's performance just by it's speed or pure data by some evaluating software. Dual Core system has better throughtput. So is depends on what you need. From my point of view, throughput is even more important than absolute speed in this age. Even though Dual Core or multi-cpu system is slower than some high-end single core system but it can handle much more tasks in certain time and less chance to hang when you doing lots of things at the same time, say, enjoying smooth DVD while copying files.

I have been using a dual xeon 2.4G system for many years and I am using a P4 3.4 in my company now. I can tell the differences. Dual is much better.

bullshit

dual is much better

我用两台机器启动同样的游戏，结果老的Intel的那台调完半天了新的Athlon那台才启动出来。家用的话我觉得根本用不了多少多线程，办公室用的话内存大小区别最明显。服务器的话用若干个Xeon这样的CPU了。

LZ,晚了,去年这个时候,双核一出,我就买了个,当时觉的比我的PII的快多了,没比较,

从南京到北京，买得没有卖的精。。。

家用办公室环境, 主频就是硬道理.

as i said, it all depends on what you need. Even though for home using, there are game lovers like you, there are also lots of multimedia designers, creaters(or people doing graphics-oriented jobs at home like 3DS Max, ProE, AutoCAD, etc) , right?

Most games do not support dual head, that is why it's slow when you loading such games. Their single cpu oriented algorithm will even further slow it down on a multi-core system.

I don't intend to judge anybody. I made these comments just because I feel it's unfair to say that dual core is not good brutally. Everything has virtually it's own reason to exist.

我的AMD 双核4200，WIN2000操作系统，下载文件（迅雷，FLASHGET，FLASHFXP）几乎都是CORRUPTED，只能用其他机器下载大文件，各位大侠有知道什么原因吗？如何在下载文件的时候指定只使用单核？谢谢

你的英语说的真好,都不象搞IT的,

不知什么对新的技术已经不感冒了。计算机是一个整体，cpu快一点儿，慢一点儿影响其实不大。
