It's kind of difficult to compare the two processors I am going to pit against each other. AMD has always had more processing power, but less cache. Intel has always had less processing power, a little bit more cache and hyperthreading. This should be an interesting comparison.
|System||Maker||Proc Model||Clock Speed||Num Cores (Physical/Virtual)||Memory|
|Custom Desktop||AMD||Phenom II x4 955 BE||3.2 GHz||4/4||8 Gb|
|Lenovo T420||Intel||Core i5 2520M||2.5 (3.2) GHz||2/4||8 Gb|
Operating System Specs
|Custom Desktop||Ubuntu 12.04 Standard install|
|Lenovo T420||ArchLinux with DWM|
Let's see how they compare! For my test I compiled the linux kernel version 3.6.0 using the default config that came with my Ubuntu 12.04 install on my desktop.
Interestingly, after the first test the kernel compile times were relatively similar. I thought that the desktop would waste my laptop, but the times were very close.
