on the i7 familiy intel did a great job on their memory controller be it dual or triple channel, both over 20gb/s even on my laptop which have a first gen i7 cpu in it, on the new amd cpu-s fx 8xxx series you can get around 16gb/s read and around 12gb/s write with a little tweaking copy is 18gb/s, when you incrase the fsb or cpu speed it can get up to 18gb read/write but thats the limit of the chip with a serious overclock best stats i could find, the geil modules i have 4x8gb 1866mhz reaches 22gb/s read 20gb/s write on an intel i7 2600 cpu, i get 15gb/s read and 11-12gb/s write on my fx8350,
Are u saying your laptop has more memory bandwith then my i7-920 triple channel as well? If so what model laptop and i7 chip? Or u talking memory read speeds instead of write, my i7-3770k came up as 27809 read speed.. None tha less these i7 cpu are nice, this memory controller tech all started with tha Athlon64, next to tha i7 cpu and of course back when things moved slower, tha Athlon64 would of been tha cpu I used tha longest, it was a great cpu for its time..
its an intel ibex peak-m hm55 chipset+i7 740qm cpu+8gigs of 1333mhz hynix rams, but its fulctuates between 15gb/s and 20 depending on the state of the os and the overall temp of the laptop, best what i measured when it was new the above stated numbers
http://www.notebookcheck.net/Mobile-Processors-Benchmarklist.2436.0.htmlSo, Number 74 on tha list hey, thats not too bad for a laptop..
My Desktop, 3770k overclocked, comes in at 2.5 on that list, I guess around a 3930k not overclocked for multithread, I get Cinebench R11.5 64Bit of 9.33.. My laptop is a acer I got for cheap, I come in at 224 on that list, I dont use it much, so I havent bothered to upgrade it, prefer tha desktop..
A dual Intel Xeon E5-2680 overclocked would sure be a nice system, quite a few bucks thou

Intel Xeon E5-2620 Sandy Bridge-EP 2.0GHz (2.5GHz Turbo Boost) 15MB L3 Cache LGA 2011 95W Six-Core Server Processor BX80621E52620
Wonder how high one could overclock this bad boy, there only around $400 a cpu.. I will have to look into it to see if its worth it, its only a 15mb cache instead of tha 20mb, those start around $1200.00..
Well quick search revealed what I thought, just a bclk overlcock only, not much..
