谢谢澄清。我看过有人贴的链接，说 AMD 约莫在 2007 年前后做了这个改动，但我不知道 Intel 那边的情况。
Thanks for clearing that up. I read the link someone posted about AMD making that change around 2007, but I didn't know what the story was for Intel.
那 Core/Core2 就没戏了。它们只有一半的 SSE2 硬件。
There's no hope for Core/Core2 then. They only have half the SSE2 hardware.
奇怪的是 Intel 有 3 个 128 位单元，但只有 2 个 128 位单元的 AMD 反而更快。
Strange that Intel has 3 128bit units, but AMD with 2 128bit units is the faster one.
