Intel i5-8400 with turbo boost technology?

[Virus-]

Hello I wish to upgrade my computer and I am studying the prices and features of processors.. The good deal seems to be the i5-8400 on Amazon, to be used with a B360m-A Asus motherboard.

https://www.amazon.ca/dp/B0759FGJ3Q/ref ... UTF8&psc=1

So this processor base frequency is 2.8ghz but it will boost it's speed on demand as the turbo boost technology.

My question is the following: is this turbo boost technology going to be fully supported by Linux Mint 19.3? the OS and the VirtualBox also? Is it a good processor to get with Mint 19.3 ?

I have a i3-4130 actually and it's not quite strong enough to sustain the base in a virtual machine.

Thanks

It's built-in to the CPU or chipset so the operating environment has nothing to do with it.

Is it a good processor to get with Mint 19.3 ?

All you're going to get are opinions. Only you can ultimately answer that question. That said, it should work fine.

That's not entirely true - out of the box Linux will use the p-state driver for Intel CPUs which do defer much of the decision making to the CPU itself, but the end user can disable turbo-boost or chose to disable the p-state driver and manually set and configure another governor entirely.

Yes, with kernel parameters, I'm aware of that but the person wouldn't be expected to know or understand that.

Ok thanks, well most processors are turbo boosted nowadays so.. it's just that most threads on Start Page are about problems with turbo boost either not working with Linux (Monitor won't show the boosts and the CPU will remain at the same base clock) or cpu over heat because of TB while doing heavy cpu tasks.. So it's either people trying to make it work or people trying to deactivate it but no comments about how good it is for the rest of the people.

As always, when something works fine we don't see much threads talking about it.. of course.

I had the suggestion of using a i5 9600k which is 100$ more then the i5 8600, it's base clock is 3.6ghz and it's 95w so it looks like a much stronger processor then the 8600. I never had a 95w processor before so I don't know how much heat they produce.

Without overclocking and assuming it's going to use the turbo boost, should I expect these to run with a standard heat sink without problems?

I know it's beginner questions..

Overall what I want to say is.. I am upgrading my computer from I3-4130 to I5-8400 or I5-9600k. So if it's not 100% sure that the turbo boost is going to work with Mint, if I pick the I5-8400, i am stucked with a processor running at base clock speed of 2.8ghz for all the cores. And I am not sure that without the turbo boost, that processor would be a worthwhile upgrade against my current i3.

But if I pick the I5-9600 and the turboost is not working, the base clock frequency for that one is 3.7ghz. And perhaps that would be a worthwhile upgrade in any case.

What do you think?

[smurphos]

The turbo boost should work fine on both. Beware it literally is just a boost, literally a few seconds of top clock speed on a couple of cores when launching apps etc. You don't get sustained boost level clock speeds, the CPUs wouldn't be able to handle the temps.

Ok thanks for the info smurphos.

Do you think i5-8400 should be a significant upgrade over the i3-4130? Considering it's 4 generations newer too and I was using the HD graphics from the i3 and planing on using the UHD graphics from the i5.

Thanks

There are quite a few comparison sites where you can compare CPU's side by side.

Thanks for the additional info smurphos

I've looked at the benchmark yesterday this is my first result. +57% for the i5 8400, whatever that means.
https://cpu.userbenchmark.com/Compare/I ... 3939vs1621

And I tried your website just 5 minutes ago
https://www.cpubenchmark.net/compare/In ... 3097vs2015
https://www.cpubenchmark.net/cpu.php?cp ... Hz&id=3097

A score of 9419 for the i5 8400 against 3432 for the i3 4130. The number is more then the double for the i5 and it's in the "high end" part list.

The numbers certainly look pretty good but that's a wild guess, does it mean that the i5 is capable of more then twice the processing capabilities?.. it's probably more complicated then that.

Looks like you had a significant upgrade too between the i5-8265U and the i5-2430M.

If you can afford the i5 9600K, I would take that in preference to the lesser model. As for your other comments, I've never had issues with turbo boost.

Cheers.

I decided to go with the i5-8400 considering the turbo boost will most likely work on Mint 19.3, Also the 9600k it's not coming with a heat sink and fan.. I was a bit uncomfortable with the total expenditure, I had to cut. Plus the 8400 should heat a bit less, fan might run at lower speed..

But thanks for the suggestion.

But thanks for the suggestion.

No worries, and happy building

Thanks all for your help here, I'll come back here to post a conclusion about the Turbo Boost with Mint 19.3. I saw some packages to download in order to test everything, I am going to do that and publish the results here.

CONCLUSION:
I am running my new computer right now with the new i5 8400 CPU and it's very fine so far, I am very glad with the results.

So to test the Turbo Boost, I ran a benchmark from VeraCrypt. The result is clear, the processor at idle 800mhz and during the benchmark calculations, it will crack it's speed to 3800mhz.

Great! ((; It's working fine.
