5 CPU Performance CPU architecture CPU X2-2 X3-2 X4-2 CPU Type X5675 E E V2 CPU Launch date Q Q Q Intel Generation Westmere Sandy Bridge Ivy Bridge Clock rate [GHz] Max number of sockets #cores per socket Multithreading 2-fach 2-fach 2-fach Performance Numbers from other Benchmarks SPECint_base2006 (speed) Oracle CPU speed in sys.aux_stats$ Remark: Oracle has an internal estimation about CPU speed in sys.aux_stats$, but none estimation about CPU throughput. This value does not correlate with SPECint_base2006 copyright 2014 by benchware.ch slide 5

6 CPU Performance Server configuration Server X2-2 X3-2 X4-2 CPU Type X5675 E E V2 CPU Launch date Q Q Q #sockets #cores #threads Memory capacity [GByte] Performance Numbers from other Benchmarks SPECint_base_rate_2006 (throughput) Software Operating System Oracle Lx Oracle Lx Oracle Lx Oracle Database System Benchware Performance Suite copyright 2014 by benchware.ch slide 6

8 Speed in CPU Performance Oracle CPU speed: arithmetic ADD operation, single process In contrast to SPEC, Benchware measures very similar speed of these processors when using Oracle data types X4-2 X3-2 X SIMPLE_INTEGER SIMPLE_FLOAT PLS_INTEGER NUMBER Simple operation Uses hardware arithmetic for SIMPLE_INTEGER, SIMPLE_FLOAT and PLS_INTEGER Uses software library for NUMBER copyright 2014 by benchware.ch slide 8

9 Throughput in CPU Performance Oracle CPU throughput: arithmetic ADD operation, system saturation Mops per core Capacity planning: X2 -> X3: + 50% X3 -> X4: + 50% Mops per core 442 Mops per core X4-2 X3-2 X Mops per core 38 Mops per core 35 Mops per core SIMPLE_INTEGER SIMPLE_FLOAT PLS_INTEGER NUMBER More throughput... More cores per socket More throughput per core - more efficient multi threading copyright 2014 by benchware.ch slide 9
