Getting the hang of it

Halo,
I am looking to upgrade my i7-6700 and I have been looking into a couple of options.
i7-10700
i5-12400

I know the i5 does much better in benchmarks compared to the i7-10700, but the reason I am unsure which one to get is because I read that Blue Iris benefits with more threads.
The i7-10700 has 16 threads, while the i5-12400 has 12.

In this case, which one should I get? This will only be used for Blue Iris and nothing more.
Thank you in advance.

Thanks for the responses. I was just confused because according the intel site...

the i7-10700 is
Recommended Customer Price$355.00-$365.00
  • Total Cores 8
  • Total Threads16
  • Max Turbo Frequency 4.80 GHz
  • Intel® Turbo Boost Max Technology 3.0 Frequency ‡4.80 GHz
  • Intel® Turbo Boost Technology 2.0 Frequency ‡4.70 GHz
  • Processor Base Frequency 2.90 GHz

while the i5-12400 is -
Recommended Customer Price$211.00-$221.00
  • Total Cores 6
  • # of Performance-cores 6
  • # of Efficient-cores 0
  • Total Threads 12
  • Max Turbo Frequency 4.40 GHz
  • Performance-core Max Turbo Frequency 4.40 GHz
  • Performance-core Base Frequency 2.50 GHz

According to those numbers, the i7-10700 seems to have a faster core/threads. But, the site also says the older CPU is more expensive?
This is just confusing.

^^^This^^^.
Generation improvements count more than the two extra cores. Power use keeps trending down for same or better performance as well.

I'm not really worried about power consumption. I just want to get the one that will be the best for Blue Iris out of the two. The one that can handle more cameras with less CPU utilization.

That's the recommended price at the time of release....

But the core/threads are faster too on the older cpu. Are you saying that even though the i5 has slower clocks and less threads, it would still perform better than the i7?

Of course it performs better The benchmarks prove it.... If the only measure was clock speed then every generation would need to have a faster clock speed which is obviously not the case...
Even the single core benchmark is about 25% faster this tells you everything you need..
 
So I ended up getting the i5-12400. Set it up with same config file, same cameras. I see no difference at all in CPU utilization. With my old i7-6700 It would hover between 12-15%. Almost exactly the same with the new one. I'm so disappointed, I thought I was going to see a big difference, but I see none whatsoever.

Lol... Cry me a River...
Where are you getting the CPU utilization numbers? Your assessment is incorrect it is impossible for a CPU that has more than two and a half times the power to result in the same CPU usage...
Regardless sell it and buy the older 10th gen i7... That's the answer you were looking for initially and it will be magical when you get it you will see a dramatic decrease in CPU usage lmao

What was the purpose of upgrading?

The 6th gen was the go to recommendation here and the only reason it isn't the recommended PC anymore is because it can't run Win11, so the i5-8500 is the new recommendation.

10-15% CPU on the 6th gen doesn't seem like a reason to upgrade?

How many cameras are you running and have you done the optimizations in the wiki?

Post the BI camera status screenshot. It would look something like this example:

I was actually comparing the CPU utilization at the bottom of Blue Iris itself and that was the same on both computers. I have them running side by side to compare.
But when I look in Task Manager, the i7-6700 shows Blue Iris at 32-34% and the i5-12400 shows 23-24%. I guess that's an improvement. But should I be getting a getter performance than 9-10%.

I feel like spending all this money for only 9-10% performance doesn't justify the expense.

Did you perform a clean windows install? There is base cpu usage for certain background tasks that may be different on the systems...
Its not a 9 percent difference its a 30 percent improvement...
 
Yes, It's a fresh installation of Windows 11. I would have thought If a CPU in Blue Iris was in the 30s with the old CPU, I would be in the teens with this new one. I guess I am asking for too much. The good thing is I have 30 days to return it.
I just can't justify this for what I am getting in return. I think I may just save a bit more and try a one of the AMD Ryzen 7s or 9s. We'll see.

Processors power vary...the issue is not the brand, its the specific model you chose...also depending on the task you might see a bigger difference at a larger load, for example if you used codeproject AI your i76700 may choke vs the 12400
 
Showing a screenshot of you BI Camera status will tell us a lot.

Many people run 4th gens at lower CPU% than you have.

Personally at the CPU% you have, I wouldn't bother with an upgrade.
