I see this i5 bash repeatedly in these forums, anyone care to share any real PD14 specific characterization?

http://forum.cyberlink.com/forum/posts/list/44106.page “Your i5 will struggle a bit”, this OP user has a I5-3570k with a passmark CPU mark of 7132

Or, are these comments from contributors simply just an echo of CL website info with very little actual end use substantiation?
Full-HD quality H.264 and MPEG2 Profiles: Intel Corei5/7 or AMD Phenom II X4
AVCHD and BD burning Profiles: Pentium Core 2 Duo E6400, or AMD Phenom II X4
2K/4K/3D video editing profile: Intel Corei7 or AMD FX series with 64 bit OS 6 GB RAM

From what I've seen, PD14 overall editing and rendering experience simply scales fairly well as a function of CPU capability, which can be easily obtained from many sites. The chart attached (passmark.com data) shows the massive overlap in I5 vs I7 compute capability of CPU's currently on the market as of today. So, instantly down playing an I5 PD14 editing capability may come with little credence. Often many users have an I5 better than many I7’s as the above two sited posts. What further muddies the water is the AMD FX series capable of 2K/4K/3D per CL note above. This AMD CPU spec overlaps many I5 CPU's performance so why the constant I5 struggle comments? For these two quoted posts, the CPU performance is 7132, above the average of AMD FX CPUs (6600 passmark) which CL claims are acceptable for 2K/4K vs basic HD video struggle comments. The chart really goes to show the above specifications by CL are, well, irrational in part other than to point out the obvious that higher quality editing profiles requires better CPU’s. No CompSci degree required for that wisdom.

Obviously a few main differences also exist between the I5 and I7 chips which too have little impact on PD14 editing from my experience.

1) smaller total addressable RAM, usually caps at 32GB vs 64 and larger. For PD14, virtually no benefit for RAM larger than 32GB.
2) some differences in the data sets of chips, from what I've seen HT only a very moderate benefit to PD14. Usually less than 5-10% improvement in editing and rendering productivity.
3) DirectX 12’s API could offer the I7 a chance to prove itself with PD14, but then again, currently PD14 editing suite of tools only utilizes DX9 and some DX11 to my knowledge.

Yes, no doubt the I7 high end CPU's substantially outperform lower end CPU's but often for users it's a $/performance trade-off decision. So what is the issue that often echoes the, you've got a underpowered I5 good luck comment from so many contributors? For those posters, are any willing to share any real back to back comparison experience you've gained of similar capability I5 and I7 CPU's with PD14? From what I've tested, 3 similar capability I5/I7 CPU’s from a passmark.com CPU mark rating in the range of ~3000 to ~8000, perform the same as long as CPU rating is the same, nothings a differentiator, but those that continue to make this comment must have applicable experience so I’m sure many would enjoy the insight.
