Athlon 700MHz Comparison

Benchmarks and Conclusion

It is important to note that as with any performance comparison, the benchmarks themselves have particular built-in limitations. For example, if a particular test will fit its entire working set within the 128K L1 cache, you will see virtually no difference between the two processors. Similarly, if the working set will fit in 192K (the total cache size of the Duron), there will likely be no difference because of the exclusive cache implementation. This may or may not reflect your situation in actual practice.

Table 3: Sysmark 2000 Individual Scores

It seems apparent that the 128K of L1 cache, plus the exclusive organization, is very effective for normal business applications, regardless of the size of the L2 cache. In fact, adding more memory was more effective in improving performance than increasing the L2 cache size, in most cases.

Of course, this exercise was mostly academic, since the Duron and Athlon are targeted to different market segments, and therefore the processor speeds are very different, with the Duron maxing out at 700MHz, and the Athlon now starting at 800MHz and up. The only conclusion one can make here, is that the large L1 cache and fast memory bus speed make the Duron a remarkable value at the low end.
