谢谢澄清。我看过有人贴的链接，说 AMD 在 2007 年左右做了那个改动，但不知道 Intel 这边是什么情况。

那 Core/Core2 没指望了。它们只有一半的 SSE2 硬件。

奇怪的是 Intel 有 3 个 128 位单元，反而是只有 2 个 128 位单元的 AMD 更快。

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.

There's no hope for Core/Core2 then. They only have half the SSE2 hardware.

Strange that Intel has 3 128bit units, but AMD with 2 128bit units is the faster one.
