Test Systems & SiSoft SANDRA 2004

How we configured our test systems:  When configuring our test systems for this review, the first thing we did was enter the system BIOS and set each board to its "Optimized" or "High-Performance Default."  The hard drives were then formatted, and Windows XP Professional (SP2) was installed. When the installation was complete, we hit the Windows Update site and downloaded all of the available updates.  Then we installed all of the necessary drivers and removed Windows Messenger from the system.  Auto-Updating and System Restore were also disabled, and we set up a 768MB permanent page file on the same partition as the Windows installation.  Lastly, we set Windows XP's Visual Effects to "best performance," installed all of our benchmarking software, defragged the hard drives, and ran all of the tests...

SiSoftware SANDRA 2004
Synthetic CPU & Memory Benchmarks

We began our testing with SiSoftware's SANDRA 2004, the System ANalyzer, Diagnostic and Reporting Assistant.  SANDRA consists of a set of information and diagnostic utilities that can provide a host of useful information about your hardware and operating system.  We ran four of the built-in subsystem tests that comprise the SANDRA 2004 suite (CPU, Multimedia, Cache, and Memory).  All of these tests were run with our Athlon 64 FX-55 and Athlon 64 4000+ processors set to their default clock speeds of 2.6GHz (13 x 200MHz) and 2.4GHz (12 x 200MHz).

When compared to the other high-end systems in SANDRA's database, our Athlon 64 FX-55 and Athlon 64 4000+ test systems outpaced the competition in the ALU portion of CPU Arithmetic benchmark, but the Pentium 4s dominated the FPU portion of the test, thanks to their inherent Hyper-Threading feature.  Neither Athlon fared as well in the synthetic Multimedia test, but again, the Pentium 4's Hyper-Threading feature gives it a huge edge in this particular test.  The Cache and Memory tests also show Intel's architecture with an advantage.  The Memory bandwidth test, however, is where the Athlons really looked good.  When used in conjunction with some fast low-latency RAM, the Athlon's on-die memory controller proves its usefulness.  Both the Athlon 64 FX-55 and the Athlon 64 4000+ were able to break the 6GBps barrier, which is excellent for a system running at stock DDR400 speeds.
