這篇評比可以幫忙在 754, 939 舉棋不定的網友.

針對 AMD 自家 socket A, 754, 939 CPU 做了一些測試. 在大部分的測試中
754 Athon 3000 @ 2.0G > 939 Athon 3000 @ 1.8G > 754 Athon 2800 @ 1.8G
看來 dual channel 在大部分的環境下, 並無法追上 200 Mhz CPU internal
clock 所造成的效能差距. 畢竟 AMD 架構下, pipeline 深度也只有十幾個 stage,
不像 Intel Prescott 有三十幾個 stage, 對 memory bandwidth 的要求, AMD
architecture 會比 Intel 小很多.
"The Athlon 64 3000+ and 3200+ Socket 939 are problematic in that they are often less efficient than their Socket 754 counterparts. To compensate for the 200 MHz reduction in frequency, they are equipped with a double channel, which isn’t...
