The CPU Mark and single thread performance are good indicators for relative ffmpeg encoding speeds. I do have i5 i7 and the named Celerons which I compared extensively with the same source files and encoding parameters. Disk I/O isn’t any problem, think of it, 5 times BluRay bitrates results in 90Kb/s < 12MB/s. Every modern disk has no problem with that and even old-fashioned nics, 100Mb/s can cope with that. >> >> Trying to determine if getting the latest dual CPU Xeon (such as E5-2690 >> v3) setup is going to be worth the significant additional cost over the >> best Haswell-E (Core i7-5960X). >> >> I've read lots of articles/posts and it is not clear to me.
