笑死人了,只有毒龙之前的AMD是不用PR值的好不好,不懂就一边去
The PR rating system was developed by AMD in the mid-1990s as a method of comparing their x86 processors to those of rival Intel. The letters PR stood for "Performance Rating", but many people make the mistake of thinking that it stood for "Pentium Rating", as the PR rating was often used to measure performance against Intel's Pentium processor.
The first use of the PR rating was in 1996, when AMD used it to assert that their AMD 5x86 processor was as fast as a Pentium running at 75 MHz. The designation "PR75" was added to the chip to denote this.
With the demise of the Cyrix MII (a renamed 6x86MX) from the market in 1999, the PR system appeared to be dead, but AMD revived it in 2001 with the introduction of its Athlon XP line of processors.
有什么好吵的,自己找找资料就清楚了,如果看不懂我可以翻译下...:sweatingbullets:
不过据我所知Athlon Thunderbird是真的没有用到PR....:wacko: |
