AMD CONFIRMED the benchmarks are Shangahi's but complained about our analysis of the numbers.
Here's it's statement:
The goal of these submissions was to enable comparisons of comparably configured servers , aka apples to apples in what you see in a mainstream, typical configuration.
· Each server uses 8 DIMMs of 2GB each. This is a typical server configuration which uses 2GB per core. There are plenty of users out there who put 8 DIMMs in a server probably would be interested in the score. In fact, it might be worth your time to see how many people use 8 DIMM servers vs. the San Clemente servers that the top Intel scores are based on. Or at least a good sidebar discussion to have.
The Intel score uses Low-Power FB-DIMM ("Memory Details: DDR2-667 CL5 LP
FB-DIMM;") If we were trying to create a "worst case scenario" as you call out
below, we would have used standard power FB-DIMM memory in the Intel server.
· Each server uses the same Ablecom PWS-702A-1R power supply
· Each server uses the same 500GB WD5000ABPS SATA II disk drive
· Each server uses the same Intel Pro/1000 PT Dual Port Server Adapter NIC
· Each server uses "Dynamic Power Profile Enabled"
Again, if we were trying to show worst case scenario we would have turned
off Power Management on the Intel server
· Each server uses the same JVM version
· Each server uses the same JVM command-line options
731 score using 2.5GHz AMD Opteron 2380 in Supermicro 2021M-UR+ with Ablecom PWS-702A-1R power supply.
561 score using 2.5GHz Intel Xeon L5420 in Supermicro 6025W-NTR+ with Ablecom PWS-702A-1R power supply.
