CCL: AMD vs for computing



Great tip Alcides ! Thanks, I was not aware of that : do you know what is adjusted exactly ?

Re the AMD 8350 vs Intel 3770, it is expected to see similar passmark scores, since the 3770 has Hyper-threading (that doubles the number of threads a physical core can handle).

IMHO, AMD cpu can be great choices if the entry price is the issue and not the electric consumption.
That is to say, if you plan to buy a machine for the long term* and have it fully loaded 24/7, I guess the extra-price of an Intel cpu would be compensated by its reduced electric consumption within months/years.
Conversely, if you are not entitled directly to the electricity bill of your machine ;) , and/or plan to run only occasional jobs on it, AMD is the way to go.

* I am not talking about possible cpu upgrades, here AMD would be a good choice. They stayed pretty socket-conservative/compatible.

The majority of the tests ignore a little known feature in the AMD 8350 octo-core BIOS called HPC which tends to speed the AMD a bit more. I used two computers with this processor and I find it a winning combination of price and performance.

Folks,

The AMD 8 proc 8350  and the Intel 3770 4 proc have the about the same parallel PASSMARK values (Intel less than 10% faster). 

Thoughts about choosing the AMD over the Intel, ignoring the diifference in PASSMARK scores?
