Running Geekbench 3.3.2 in 32-bit mode for the following: 1) 2011 cMBP i7-2620M @ 2.70 GHz with 16384 MB 1600 MHz DDR3 I get memory performance scores: single-core 2943 and multi-core 3265. 2) 2015 rMPB i5-5287U @ 2.90 GHz with 16384 MB 1867 MHz DDR3 I get memory performance scores: single-core 2549 and multi-core 2448. So, the 4 year newer machine, with faster memory and faster CPU, is about 20% slower. Could someone please explain this? Both machines are on Yosemite 10.10.3, the older machine has a SATA SSD, and the Geekbench for the new machine is about 20% faster for integer and floating point performance calculations.
