SiSoft Sandra Memory Test

Surprisingly enough, the memory bandwidth on the Venice running at 1.8 Ghz is quite a bit less than what is seen with the Winchester at the same clockspeed. The 3 Ghz P4 rounds up the rear and is a ways behind the Venice.

Rightmark Memory Analyzer

The P4 does pretty well on the read portion of the Rightmark Memory test. Like the Sandra test, we see that the memory bandwidth on the Venice is quite a bit lower than the Winchester, the average read is about 500 MB/s off of what is seen with the Winchester.

Similar story on writing to memory. The Venice is again, significantly behind the Winchester when both are clocked at 1.8 Ghz.

When we look at memory latency, the picture changes drastically. AMD has been able to significantly lower latency with the reworked memory controller. The average case which is remarkably close to the worst case latency has been reduced by about 16% at the same clockspeed. Notice that although the speed of the memory controller scales with the processor speed, the relationship is not 1:1.

With read/write and latency factored in, RightMark ranks the Venice slightly behind the similarly clocked Winchester.
