Interested in the differnces with these 2 when it comes to BI

I have 2 X 8mp and 4 X 2mp that i am looking to upgrade to 6mp, currently running on a i5 3450

There are almost no price differences in the 2, but different thread

https://www.pcgamesn.com/intels-weird-eight-core-9700k-is-somehow-20-quicker-than-the-8700k-but-with-66-fewer-threads

i7 9700k: 8 Cores, 8 Threads @3.6GHz, Coffee Lake
i7 8700k: 6 Cores, 12 Threads @3.7GHz, Coffee Lake

The 9700k scores higher in benchmarks, because apparently 2 real cores beats 6 virtual ones. It isn't a huge difference but I'd still go for the 9700K (or 9900K) if buying a new CPU today.

I am excited for the launch of AMD's 3rd-gen Ryzen CPUs in 3 days. In theory, these may be able to outperform Intel at similar power consumption. Where Intel has the advantage of Quick Sync providing H.264 decoding hardware acceleration, AMD should have the advantage of more cores and significantly better energy-efficiency (finally), so I am thinking the 12 and 16 core models will probably be a step above the 9900K in Blue Iris. However, to take full advantage of better efficiency, it will be necessary to use a very efficient graphics card and maybe also an older AMD motherboard. The new X570 motherboards are said to draw 15 watts all on their own.

Finally some competition to put some fire under intel.

The 9900k is more expensive, unsure if the price will come down anytime soon!
I am not concerned about power usage, i have solar and on a good feed in tarrif - i dont get power bills

Would 1 CPU have an advantage over another if i have several 6mp cameras (as well as a few 8mp)
Threads vs's cores? - looking at the bench marks the 9700 is better - but not by a whole lot
I am also interested in the 3rd gen Ryzens, however prefer to see some results with BI first

1 other question... RAM speed count for much?
Reading a few posts i get the imnpression 4 X 4gig sticks would be better than 1 X 16gig or 2 X 8gig
Is there much in it?

Ref data point - for those in the USA following this:

Microcenter currently has reduced prices on CPUs ( certainly AMD is influencing this! )
Intel Core i7-9700K - $329.99 ( list $499.99 )
Intel Core i7-8700K - $299.99 ( list $399.99 )

When I was checking for a single threaded application, it looked like the i7-8700K had a slight edge vs the i7-9700K.

Hoping the newer AMD chips coming out will provide good competition to intel on the i5/i7 front.

That is interesting. Is anyone saying why this is better with BI?

Side note rethink the 6mp cams. Most perform poorly in low light.

The 2 X 8mp i have are great at night (better than my 2mp foscams), I cant see the 6mp being much different? (although i dont have anything to compare against other than reviews on this forum)
I have street lighting and a few cameras out the front - the IR on other cameras light up my yard well - that may change if i replace the 2mp with 6mp

All I am reading in regards to Cores vs Threads - Cores wins out on a simular cpu
When it comes to BI, can we rely on benchmarks to compare?

Would this be the segment with most relevance?

RAM speed and using dual or quad-channel memory mode shouldn't matter for any real-life use case, only really shows up in benchmark or very memory intensive situations. It's a clever way to sell 2x or 4x as many memory sticks for those few people that will really investigate it beyond benchmarks.

Technically is it faster, yes, will a normal human likely see it running an NVR, not likely.

I have i5-8500 running 2 new 8mp dahua 11000 bitrate each - stays at a nice low 30-45% - playback is 70% CPU usage.
i will be adding a lot more that I have not moved over to this BI machine yet and see how it goes.

i have 2 8gb balliastix 2400 - running 1 in each alternative slot so dual-channel mode. It seems fine.

that is a very high load for 2x8mp cameras unless you are running really high frame rates.

15fps. And I think iframe is half of that if I recall correctly.
I am using CBR encoding.

It is this model:
Dahua HFW-1831E in-depth review

I am not sure why it is just high but maybe I messed up a setting. If you want to remote connect in to check it all out let me know maybe I can share my mess up to avoid others having the same problem.

This is interesting to me,

I like all things computer related,
I have a ryzen gen2 cpu desktop as a daily user for work and play circa £800 build approx 2 years ago, but nothing fancy.

My BI machine is a HP elite desk with 6th gen i5 in there.

The ryzen pc has 16gb ram and the HP has 8.

Whst I found really interesting is that as a bit of fun I loaded BI on to both machines the ryzen only has the demo mode as I wasnt going to pay for a second license to just have a bit of fun.

The interesting part is the HP with all 9 cams loaded 2x3mp 6x2mp and 1x720p camera runs at about 40-50% cpu load this is using direct to disk and also quick sync.

On the rysem system same BI setup with all cams at same frame rates etc. Obviously no direct to disc and no quik sync,
Has all my other stuff on it and emails etc syncing in the background.
This runs at 30-35%

Haven't done any specific test for energy or anything as I was basically doing a fun test on CPU load.

I found that interesting because of the general conceous on here with regards Intel CPU's

Be interesting to hear @fenderman thoughts on this as I appreciate his knowledge around these areas.

I'm not saying this is conclusive or trying to persuade anyone to actually use a ryzen system over an Intel as theres no proof other than my fun little load test to back anything up.

Just found it interesting

Look at the bottom item here about power options. Optimizing Blue Iris's CPU Usage | IP Cam Talk It could be that your CPU is throttling down to save power, and therefore causing CPU usage to only appear higher than normal.

@reeves1985 Without knowing specific CPU models, that is not really meaningful information.
I was just actually looking at the cpu details
The HP elite desk using i5-6500 @3.2GHz
8GB Ram
The system system is
AMD Ryzen 5 1600 6 core @3.79GHz
16GB Ram

Yes I have all those settings in BI5. I will monitor my situation and see if it changes and keep everyone updated. I am not sure what is going on. I have a few i5-8500 comps so I might switch systems to see if it fixes anything.

Thanks

So I went and got the i7 9700k - now debating the RAM, has 1 stick of 8gig (2600) - debating another 8gig or 2 X 8gig of 3600

How much would RAM speed assist in this application?
