Hi Simon,
I found some threads in which you discussed the Nehalem processors
vis-a-vis speedups in R (on Mac). I have to decide between getting a
Core 2 Duo 3.33 ghz and the Core i7 2.8 ghz iMac. The critical part
of my code
I've been doing consistent time benchmarks across a range of computers
(no Nehalems yet). A few of these are OS X related and might be of
interest.
The test systems:
A. MacPro: Dual Quad core 2.8 GHz, 32 GB RAM. Running either OS X
10.5.6, 10.6 or Slackware 12.2
B. MacBook Pro: Intel Core 2 Duo
It's been a while since this thread, but I could finally lay hands on
a Nehalem to test, so I thought I'll share some tidbits.
My worries turned out to be true and Nehalems are not as fast with R
as the synthetic benchmarks would make you think. The results are a
mixed bag, but in overall

Clearly, benchmarks never tell the full story and there may be uses
that take advantage of the one or another
