根据Fudzilla网站的亲身体验,至少在多媒体方面,已经可以确定,同频率的情况下,Barcelona K10处理器的性能高于 Core 2 Duo,K10的主要问题是如何运行在更高的频率上。 在所有的评测中,K10在95%的情况下都可以打败同频率的扣肉,但是K10目前最高只能是2.5GHz,对比的Penryn却可以达到3.4GHz,另外Penryn还有更多的指令集,包括完整的SSE4等,而K10的SSE4A指令集只是SSE4的一个子集。
根据AMD官方表态,用于服务器的Barcelona Opteron将在8月中旬投产,随后相关系统开始出货,而桌面版Phenom在11月份登场,首先是四款型号,Phenom FX-80、X4 GP-7100/7000和Phenom X2 GS-6550,明年年初还会有另外五款四核心和六款双核心跟进。

Barcelona faster than Core 2 Duo

Clock to clock
We had a privilege to see Barcelona K10 multimedia scores and we can confirm that clock to clock, it runs faster than Core 2 Duo. The big problem is how Barcelona K10 goes against Core 2 Duo at much higher speeds.
Instructionwise when you compare all known instructions K10 beats Conroe, there is absolutely no question about it. In 95 percent of cases K10 is faster clock to clock but the real issue is what happens to compare 2.5 GHz K10 versus Penryn at 3.4 GHz.
The other issue is that Penryn has more instructions including SSE4 while K10 has just subset of it.
