i7 vs. i5; 1366 vs 1156?
Posted: Tue Dec 22, 2009 4:54 pm
Just bought NeatVideo Pro plug-in over the weekend. Love love love it! Now I need a processor upgrade from my C2Q6600. Has anyone benchmarked the latest processors?
I'm currently doing most of my video work in 1440x1080 (HDV), and will be moving to 1920x1080 soon. Is rendering with NV processor limited or memory bandwidth limited? I was spending 3-4:1 rendering time before NV, after NV the ratio is 12-15:1 (and getting much much cleaner video, of course) with all setting at default (except the sampling box as user configuration). Is that indicative of the process being processor limited? On the other hand, the quad core processor is loaded at only 60-70% on each of the four cores according to the Windows Taskmanager.
My question is two fold:
(1) does hyperthreading in i7 help rendering a single project (wmv h.264 output) pulling from 2-3 m2t or avi (the latter is pre-rendered intermediates)? The 60-70% processor load in rendering real projects has me scratching my head. Should I render two projects simultaneously as a time saver overall?
(2) does triple channel memory in 1366pin i7's make a difference vs. the 1156pin dual-channel i7's?
Any advice is much appreciated. Thank you in advance.
