IBM, Moore's Law and the POWER 5 chip

"IBM's recent pSeries benchmark ought to raise a good number of eyebrows. Unix server benchmarks had previously been a game of leapfrog between IBM and HP, with IBM looking increasingly strong in the last round (in 2003) when its p690 server with 32 processors demonstrated a slightly higher transaction rate than HP's 64 processor Itanium 2 server. The latest benchmark from IBM leaves both previous benchmarks in dust. In the TPC-C benchmark, IBM demonstrated over 3m transactions per minute (tpmC) almost three times more than the previous highest result of 1.2tpmC, posting a 37 per cent price performance advantage in the process."
