Our test results make it clear, however, that Intel probably won't be able to catch up with AMD using processors based on the Netburst microarchitecture; it will have to wait for its new microarchitecture for that. Despite being produced at 90nm and having a much lower clock speed, the Athlon 64 FX-60 nearly ran the tables in our array of benchmarks, and it did so while consuming less power—both at idle and under load—than the Pentium Extreme Edition 955. The FX-60's performance dominance wasn't always deep, but it was very wide, with the top spot in only a few tests going to an Intel processor.I had kind of expected our use, this time out, of newly compiled 64-bit binaries, multithreaded applications that can take advantage of Hyper-Threading, exceptionally fast Crucial 800MHz DDR2 memory, and multithreaded graphics drivers to give the Netburst architecture something of a boost in relative performance. Turns out that wasn't the case.
By launching their new dual-core Athlon 64 FX-60 processor, AMD responded worthily to Intel’s Pentium Extreme Edition 955. There were quite a few cases when the new Intel CPU could probably shaken AMD’s leadership, however, the just launched AMD Athlon 64 FX-60 doesn’t leave the competitor even a single chance in almost all of them. Among the indisputable advantages of the newcomer from AMD targeted for the high-end pricing segment of the market I should list lower power consumption and heat dissipation than that of the competitor’s solutions. In other words, despite the recently announced 65nm Presler core from Intel, the overall situation in the market remains unchanged. CPUs with NetBurst architecture cannot be regarded as a successful alternative to contemporary AMD solutions. So, at least until H2 2006, when Intel is going to release a principally new Conroe processor, AMD will remain the leader by providing the fastest and most economical CPUs for the top-end market segment.However, we shouldn’t say that Presler got completely and hopelessly defeated by the new Athlon 64 FX-60. Due to the new finer production technology, the new dual-core processors from Intel can boast excellent overclocking potential. As for the frequency potential of the AMD processors, it has been almost completely exhausted by now. As a result, when we compare the results demonstrated by the overclocked AMD Athlon 64 FX-60 and Intel Pentium Extreme Edition 955, the former is not always the winner. So, if you do not mind your system being a little bit noisy and generating quite a bit of heat, then Pentium Extreme Edition 955 might be a way to go.
