RIP Dunnington: HP’s 4P/24-core Istanbul Takes VMmark Summit

July 15, 2009
HP has simultaneously achieved two near identical VMmark scores with their ProLiant DL585 G6 rack server and ProLiant BL685c G6 blade, claiming the summit from the reigning 24-core champion. Since first establishing the 24-core tier VMmark in September 2009, the Intel “Dunnington” 6-core processor (FSB architecture) has gone unchallenged. Now, with the release of the Opteron 8439SE raising the performance bar and the Opteron 8435 making a clear price-performance case, Dunnington’s vacation is over.

Today’s Istanbul-based achievements – established in the same memory footprint as the top Dunnington – renders the venerable processor all but obsolete, besting the champ by 4 tiles (24 more virtual machines) with a score-tile ratio of 1.5 for the rack system and 1.46 (same as the Dunnington at 14 tiles) for the blade. Using the HP and IBM on-line configuration tools, we established the retail (on-line) price for each system – down to the Fiber Channel HBA’s – and compared them for $/VM value. Here are the results:

Cost/VM 3rd Party $239.27 $227.97 $276.73

The results indicate a 21-38% savings per-VM for Istanbul over Dunnington in the 4P/24-core virtualization space. This is bread-and-butter territory for VDI implementations and SQL virtualizations, and Intel’s last remaining market place for the Dunnington processor. With the top-bin Istanbul weighing-in with 3% better performance, 18% less power consumption and 30% more capacity against Dunnington at the same price point, Intel’s 4P gambit is played-out and Nehalem-EX cannot arrive too soon for Intel.

It is worth asking the question: does the HP ProLiant 4P/24-core offer the best value? The answer depends on the value proposition. From a straight $/VM vantage point, the HP DL385 G6 comparison demonstrated a more economical $182/VM – a difference of $40/VM lower than the BL685c G6 – so the 2P rack system still comes out on top for the absolute bottom-line concious. However, for applications like SQL consolidations, the additional savings in licensing on 4P platforms versus 2P platforms dwarfs this differential.

What is clear: AMD’s Istanbul solution will remain unchallenged in the 4P space both in raw performance and in price-performance until Nehalem-EX is delivered. That means if Nehalem-EX does not arrive in Q3/2009, the market will likely wait for Q1/2010 to make any long-term purchasing decisions in anticipation of the new platforms slated to break-in the new year.
