AMD Shanghai Launch - Database Testing

Scalable Reads Performance
In this benchmark Harpertown is able to lead for three of the five loads points, and Shanghai leads for the other two. At the lower load points, Harpertown is able to lead by as much as 26%, but at the two top load points the Shanghai lead drops to just 2%. Again, the performance of Shanghai @ 2.7 GHz at the lower load points is not significantly better than Barcelona @ 2.3 GHz. At load points four and five the faster Shanghai core is able to easily outpace Barcelona.
The results are similar to previous CPU utilization graphs.
Again, Intel is getting closer to AMD efficiency but not quite. Shanghai uses around 20% less power than the lowest power consuming Harpertown configuration.
Shanghai is able to lead on the majority of the load points here, but the four DIMM Harpertown configuration is able to match it for the first two load points. Shanghai is able to lead Barcelona by as much as 37%.
Note: The line for Harpertown four DIMMs is dotted in the above graphs because we did not actually run this configuration but speculate this is the power consumption based on idle power consumption analysis.

I mean really, how many times AT? You didn't seem to have a problem with i7 results, what's the hold up? Or is this going to be another dfi790, 790fx, 790gx, 780g etc, etc, etc, type of review. You know, the kind where you pay lip service to it, and then go back to cuddling up with Intel.... FraudsLTG - Friday, November 14, 2008 - link
Another power variable I didn't see in the review - The harpertown that matches AMD's price listed is the lower TDP model.The E5450 is 80w TDP
The X5450 is 120w TDP

Sorry just found it on the benchmark graphs - looks to be the "E" version.LTG - Friday, November 14, 2008 - link
It would be very helpful to know this because almost all new Intel systems support the lower voltage FB-DIMMs.segerstein - Friday, November 14, 2008 - link
Yes, the future will be Muslim. AMD is going to get bought by rich UAEs. The next architecture will be called Istanbul.Why not Byzantium or Constantinople?

Maybe because Istanbul is an actual place, and not just a historic name?alpha754293 - Thursday, November 13, 2008 - link
You mentioned in this brief review that the FB-DIMMS remove any power efficiency advantage that the Intels othewise might have had.Does the AMD systems also use the FB-DIMMS?
Also, how are you measuring the power consumption because a lot of the charts/graphs look nearly exactly identical, which would seem odd unless it was using the CPU (i.e. all of the application profiles) were EXACTLY identical.

AMD does *not* use FB-DIMMs, and very likely never will. The power penalty appears to be something like 7W per FB-DIMM, possibly even a bit more, and the performance advantage... well, it doesn't exist. FB-DIMM was an idea to add more memory on a single channel at the cost of increasing latency. I just don't think it really made enough of a difference to affect the vast majority of server users.Johnniewalker - Thursday, November 13, 2008 - link
Now that would be cool!acejj26 - Thursday, November 13, 2008 - link
Memory frequency is now 800 MHz. Bandwidth is a function of the frequency, but they are not the same.
