The Cost of Benchmarks

May 8, 2009

We’ve been challenged to backup our comparison of Nehalem-EP systems to Opteron Shanghai in price performance based on prevailing VMmark scores available on VMware’s site. In earlier posts, our analysis predicted “comparable” price-performance results between Shanghai and Nehalem-EP systems based on the economics of today’s memory and processors availability:

So what we’ve done here is taken the on-line configurations of some of the benchmark competitors. To make things very simple, we’ve just configured memory and CPU as tested – no HBA or 10GE cards to skew the results. The only exception – as pointed out by our challenger – is that we’ve taken the option of using “street price” memory where “street price” is better than the server manufacturer’s memory price.

Here’s our line-up:

System Processor Qty. Speed (GHz) Speed (GHz, Opt) Memory Configuration Street Price
Inspur NF5280 X5570 2 2.93 3.2 96GB (12x8GB) DDR3 1066 $18,668.58
Dell PowerEdge R710 X5570 2 2.93 3.2 96GB (12x8GB) DDR3 1066 $16,893.00
IBM System x 3650M2 X5570 2 2.93 3.2 96GB (12x8GB) DDR3 1066 $21,546.00
Dell PowerEdge M610 X5570 2 2.93 3.2 96GB (12x8GB) DDR3 1066 $21,561.00
HP ProLiant DL370 G6 W5580 2 3.2 3.2 96GB (12x8GB) DDR3 1066 $18,636.00
Dell PowerEdge R710 X5570 2 2.93 3.2 96GB (12x8GB) DDR3 1066 $16,893.00
Dell PowerEdge R805 2384 2 2.7 2.7 64GB (8x8GB) DDR2 533 $6,955.00
Dell PowerEdge R905 8384 4 2.7 2.7 128GB (16x8GB) DDR2 667 $11,385.00

Here we see Dell offering very aggressive DDR3/1066 pricing [for the R710] allowing us to go with on-line configurations, and HP offering overly expensive DDR2/667 memory prices (factor of 2) forcing us to go with 3rd party memory. In fact, IBM did not allow us to configure their memory configuration – as tested [with the 3650M2] – with their on-line configuration tool [neither did Dell with the M610] so we had to apply street memory prices. [Note: the So here’s how they rank with respect to VMmark:

System VMware Version Vmmark Score Vmmark Tiles Score/Tile Cost/Tile
Inspur NF5280 ESX Server 4.0 build 148592 23.45 17 1.38 $1,098.15
Dell PowerEdge R710 ESX Server 4.0 build 150817 23.55 16 1.47 $1,055.81
IBM System x 3650M2 ESX Server 4.0 build 148592 23.89 17 1.41 $1,267.41
Dell PowerEdge M610 ESX Server 4.0 23.9 17 1.41 $1,273.59
HP ProLiant DL370 G6 ESX Server 4.0 build 148783 23.96 16 1.50 $1,164.75
Dell PowerEdge R710 ESX Server 4.0 24 17 1.41 $993.71
Dell PowerEdge R805 ESX Server 3.5 U4 build 120079 11.22 8 1.40 $869.38
Dell PowerEdge R905 ESX Server 3.5 U3 build 120079 20.35 14 1.45 $813.21

As you can easily see, the cost-per-tile (analogous to $/VM) favors the Shanghai systems. In fact, the one system that we’ve taken criticism for including in our previous comparisons – the Supermicro 6026T-NTR+ with 72GB of DDR3/1066 (running at DDR3/800) – actually leads the pack in Nehalem-EP $/tile, but we’ve excluded it from our tables since it has been argued to be a “sub-optimal” configuration and out-lier. Again, the sweet spot for price-performance for Nehalem, Shanghai and Istanbul is in the 48GB to 80GB range with inexpensive memory: simple economics.

Please note, that not one of the 2P VMmark scores listed on VMware’s official VMmark results tally carry the Opteron 2393SE version of the processor (3.1GHz) or HT3-enabled motherboards. It is likely that we’ll not see HT3-enabled scores nor 2P ESX 4.0 scores until Istanbul’s release in the coming month. Again, if Shanghai’s $/tile is competitive with Nehalem’s today (again, in the 48GB to 80GB configurations), Istanbul – with the same memory and system costs – will be even more so.

Update: AMD’s Margaret Lewis has a similar take with comparison prices for AMD using DDR2/533 configurations. Her numbers – like our previous posts – resolve to $/VM, however she provides some good “street prices” for more “mainstream” configurations of Intel Nehalem-EP and AMD Shanghai systems.
