Winbench: CPUMark, FPUMark
This content was originally featured on Amdmb.com and has been converted to PC Perspective’s website. Some color changes and flaws may appear.
The WinBench suite of tests is also provided by ZDNet. The only two tests that you will see here are the CPUMark and FPUMark results. The CPUMark test is heavily dependant on the L2 cache, and will show you exactly how much difference there is between the 256K of the Thunderbird and the 64K of the Duron. The FPUMark is a test of the floating point capability of each of the processors.
The lack of a higher amount of L2 cache on the Duron processor is what is causing the lower scores here in the CPUMark test. While some people might tell you that this test and results are immaterial, I ask you take a good look at ALL of the benchmarks. If the processes and projects that you will using your PC for are heavily L2 cache dependant, then this test may prove to show you that that increased 256K L2 cache on the Thunderbird processor is worth the added cost.
Since the CPU core of these two processors are identical, it is no surprise that these test results are as close as they are: nearly identical. Since L2 cache does not come into play here, and simply the floating-point core and clock speed are tested, these two processors and physically identical in this respect. The Duron being the cheaper CPU, gets the hands down from this test.
