To estimate the general processor performance we resorted to a popular PCMark Vantage benchmark that emulates several scenarios with workload typical of home desktop systems:
Overall we can say that AMD Athlon X2 7750 and 7750 processors do not set the Thames on fire. While the top model shows comparable speed to that of the top Brisbane processor, - Athlon X2 6000, the results of the Athlon X2 7550 get lost on the diagrams among the columns representing previous generation processors.
As fir the statement made by AMD marketing department saying that new Athlon X2 compete against Intel Pentium Dual Core, it is generally correct. Athlon X2 7750 and 7550 outperform Pentium DC E2220 built on 65nm core and the top model of the two also outpaces Pentium DC E5200 on the new Wolfdale-2M core. So, according to the results in PCMark Vantage, Athlon X2 7750 seems to be running approximately as fast as the recently announced Pentium DC E5300.
