Our Test Systems and SANDRA

 

How We Configured Our Test Systems: When configuring our test systems for this article, we first entered their respective system BIOSes and set each board to its "Optimized" or "High performance Defaults". We then saved the settings, re-entered the BIOS and set memory timings for either DDR2-1066 (AMD) with 5,5,5,15 timings or DDR3-1333 with 7,7,7,20 timings (Intel). The hard drives were then formatted, and Windows Vista Ultimate was installed. When the Windows installation was complete, we updated the OS, and installed the drivers necessary for our components. Auto-Updating and Windows Defender were then disabled and we installed all of our benchmarking software, defragged the hard drives, and ran all of the tests.

 Preliminary Testing with SiSoft SANDRA XII
 Synthetic Benchmarks


We began our testing with SiSoftware's SANDRA XII, the System ANalyzer, Diagnostic and Reporting Assistant. We ran three of the built-in subsystem tests that partially comprise the SANDRA XII suite with AMD's new Phenom X4 9850 processor (CPU Arithmetic, Memory Bandwidth, and Memory Latency) and with a B2 revision Phenom clocked at the exact same frequency for reference.  All of the scores reported below were taken with the processors running a clock speed of 2.5GHz, with 2GB of DDR2-1066 RAM running in 128-bit ganged mode.  Please note however, the Phenom X4 9850 has a faster memory controller frequency of 2.0GHz, the B2 revision chip had a 1.8GHz memory controller clock.

If you compare the perfomance of the B2 revision chip with the TLB patch enabled to the new B3 revision chip, you'll notice some dramatic differences.  SANDRA's CPU arithmetic benchmark reports similar scores for both chips.  The Memory Bandwidth test, however, shows the B3 chip with a huge advantage (8.4GB/s vs. 11.2GB/s).  And the latency test also shows the B3 chip with a huge edge in latency (232ns vs. 83ns).  These large deltas can be directly attributed to the TLB errats which has been resolved in the B3 revision Phenom X4 9850.
