My quad core i5-3550(a)3.3GHz converting a dvd-clip with
no extra filters clocks in at 3-3.5fps. LinuxMint 64-bit.
Adding my HTPC as an extra encoding server converts the same clip at 5-6fps. It runs
adual core i3-2100(a)3.1GHz with HT, so 4 threads. Win7 64-bit.
This seems to suggest that HT helps with DVD-o-matic. But I'm not certain. Is it
better to run your CPU with HT off and use only 2 threads, vs having HT on running 4
threads. My gcc-compiles at work do not care for HT.
On my 2310 dual core notebook (DVD-o-matic 64-bit) I can only get into full CPU load mode
when I dial in 4 threads in DVD-o-matic. When I choose 2 threads, I get all 4 logical CPUs
loaded, but only to 50% aggregated load at around 0.9frames/s.
When I choose 4 threads, all 4 logical CPUs are loaded fully, aggregated 100%, and it goes
up to 1.4frames/s peak.
3 is probably most economical at slightly below 80% and 1.2frames/s, and there is some
headroom to have other things running on the machine.
As I will be doing more and longer encodings in the future, I'm in the market for a
desktop machine with some more cores and cpu cycles/s. I might have some DualCore desktops
sitting around to aid.
Would love to hear what others are getting - someone with AMDs?
