i3-8100 vs i3-8350k, does the 8350k max out on load?

[swaggycreeper11]

I am going to build a new pc and i am thinking of bying an i3-8350k. I first thought of bying an i3-8100, but I prefer 8350k, because it has base 0.4ghz more, can be overclocked up to 5ghz and has +2mb cache memory. My friend told me that i should not buy i3 8350k because it is unlocked, which results in the cpu's cores maxing out on load. So, my questions are:
1) Do unlocked cores max out on load much easier than the locked ones?
2) Can the pc motherboard or/and its ram affect cpu's load?
3) Does the i3-8340k actually max out on load easier than the i3-8100?
4) Is Cryorig H7 (cooler) good enough for the i3-8350k

PC specs:
gpu : Gigabyte GeForce GTX 1060 6GB
Motherboard: Z370 aorus gaming 5 (rev 1.0)
PSU : Corsair CX series CX650
HDD : Western Digital Blue 3.5" (7200 rpm)
Ram : HyperX Fury Black 8GB 2666 Ghz
Case : CoolerMaster MasterBox 5 (Window)

Also, the reason why my friend thinks that unlocked cores max out on load easier than the locked ones is because the unlocked ones have a little percentage of them already used in order to be able to overclock them (a part of the cores are basically useless when not overclocked).

That's not how it works at all. The non-K CPUs are literally throttled down. So, they are artificially slowed down by the manufacturer. The unlocked K-series processors have greater potential because they aren't artificially slowed down. They are typically built on better silicon too. Which is what allows them to have the overclocking head room. Plus, they are faster without even being overclocked. The CPU with more "wasted" potential would be the non-K CPU.

FYI, not to be rude, but your friend really doesn't sound like he knows what he's talking about.

I dont to use turbo because i dont think it is that safe. I will just buy the i3 8350k.

You realize turbo is a stock feature and perfect safe, right? You'd rather buy an unlocked chip (and presumably overclock).
While overclocking isn't exactly dangerous... there are some (minor) risks involved. Whereas turbo is a stock feature and perfectly safe.

Also, the reason why my friend thinks that unlocked cores max out on load easier than the locked ones is because the unlocked ones have a little percentage of them already used in order to be able to overclock them (a part of the cores are basically useless when not overclocked).

No. Just no. That's not how anything works, remotely. In a very simplistic sense, at stock that added 'speed' doesn't 'exist' until/unless you overclock.

Ultimately, you've been given viable options and rationale as to why.
If you're bound and determined to buy an 8350K &/or wish to follow your friends misleading advice, by all means do so.

I guess i am just going to buy an i3 8350k... I wont be using stuff that uses more than 4 cores that much, so I dont think that I should go for the i5 8400.

 

[Barty1884]

I guess i am just going to buy an i3 8350k... I wont be using stuff that uses more than 6 cores that much, so I dont think that I shouls go for the i5 8400.

.....and I think you should, based on the information provided.
I think we're at an impasse :lol:

Of course, you're free to buy whatever you want - I'm only trying to provide a recommendation.

 

[swaggycreeper11]

TBH I am really confused... I don't know which one I should buy. On the first hand the i5 has 6 cores and 6 threads, less power consumption and 1mb cache more. On the other hand the i3 has more base clock speed and can be overclocked without reaching high temperatures compared to others. I guess that I dont care that much about power consumption and the 1 bonus mb cache , but having 6 cores and 6 threads sounds like sth that is important. The i3 is definetely better at things that don't need more than 4 cores and I dont actually play games and use software that needs those 2 more cores. I dont know if this will be true in the near future, but all games etc. don't actually neccessarily need more than 4 cores, although 4 CPUs with 4 cores exist for many years. I AM REALLY CONFUSED RIGHT NOW....

On the first hand the i5 has 6 cores and 6 threads, less power consumption and 1mb cache more. On the other hand the i3 has more base clock speed and can be overclocked without reaching high temperatures compared to others.

As I posted earlier, it's 100MHz difference (before overclocking) vs the stock turbo boost of 4 cores on the i5-8400 that won't make any noticeable difference in performance in tasks that require 4 cores or less.

The i3 is definetely better at things that don't need more than 4 cores.

No, it's not. At least, not conclusively. Might have a very marginal edge in some tasks, but for all intents & purposes, they'd perform identically.

I dont actually play games and use software that needs those 2 more cores. I dont know if this will be true in the near future, but all games etc. don't actually neccessarily need more than 4 cores, although 4 CPUs with 4 cores exist for many years.

i3-8350K = $169
You'll need a cooler. Say $20 minimum
To overclock, you'd need a Z370 board. Minimum of $80

Not a great cooler, just serving the example:

Same or better performance, for ever so slightly less money.

You're really comparing overclocking potential vs 2 added cores.

To me, it's a no brainer.

 

[swaggycreeper11]

If I buy the i3 8400, will I be ok if I always have it on 4ghz?

 

[Barty1884]

The system will auto turbo to 3.8 or 3.9, as I mentioned.

Depending on the board there may be "MCE" options (Multi-Core Enhancement) to allow it to run at 4GHz..... but not all boards will.

At worst, you'll see 3.8GHz across all cores.

Also, the reason why my friend thinks that unlocked cores max out on load easier than the locked ones is because the unlocked ones have a little percentage of them already used in order to be able to overclock them (a part of the cores are basically useless when not overclocked).

Your friend watches too much crappy utube.

 

[swaggycreeper11]

1) Does it turbo automatically?
2) Doesn't it reach high temperatures when on turbo?
3) Won't it start having worse performance if on turbo (after like a year)

 

[Barty1884]

1. Yes.
2. HighER temps, yes... but still within safe, operating spec with the stock cooler.
3. No.

 

[swaggycreeper11]

If I buy Cryorig H7 (cooler), will it stay on low temperatures even when on turbo?Also, it is able to turbo, whithout changing any settings on its BIOS or anything like that?

 

[volkgren]

Intel Turbo Boost is the default setting on most all motherboards, so nothing to change in bios.

The Cryorig H7 is a good cooler and will keep the i5-8400 cool enough without worry.

 

[logainofhades]

For an i5 8400, the H7 would work fine, or better yet, the H5 universal, if you have the clearance in your case. Turbo is automatic. You can either enable or disable turbo, via the bios. Default is turbo on.

Also, I would stop taking PC advice from your friend. His knowledge of how things work is not something I would consider reliable.

 

[swaggycreeper11]

I was going to buy everything for my pc in the middle of October, but I found out that the i5-8400 was not available in any shop in my city (because Intel has a problem with 8th gen CPUs), and that it would be available much later( I could buy one at some certain shops, but they sell this CPU 100€ more). As a result, I had to quickly choose if I want to buy the i5 8400. And I think i made the right decision which was to buy the i5. I would normally buy the i3 8350k but I guess that would be a mistake. The i5 is cheaper, has 2 cores and 2 threads more (which makes it more future proof and better at multi tasking), has better temperatures and 1 mb cache more. The i3 has 0.2 ghz base clock speed more (if the i5 is on turbo, which is the whole point of this cpu), and can be overclocked up to 5 ghz. TBH I wouldn't ever overclock the i3, and if i wanted to overclock it in order to notice any difference, i would have to buy a liquid cooler. Also, the i3 reaches 100% usage pretty easily, which results into screen stuttering and the cpu not being able to handle anything more. The i3 and i5 are actually the same at gaming, but the i5 is way better at multi tasking and editing. The i3 is only worth it if going to be overclocked and slightly better at single core and quad core stuff. Whatever, I tried to find the i5 in my city (with a good prize) , and it actually is being sold in only one shop, which has only 1 copy of it. I have booked it and will buy it on Monday.

 

[volkgren]

Good choice.

 

[swaggycreeper11]

Should I connect my monitor with my motherboard or with my GPU?

Your GPU.

 

[swaggycreeper11]

I am planning to play on 1080p 75hz. Will buing an 1070 be an overkill?

 

[Barty1884]

Similarly, it depends on the title...... but probably not. 1080p, High/Ultra settings, 75Hz is probably going to need a 1070, minimum (most of the time)

 

[swaggycreeper11]

60 hz?

 

[Barty1884]

Generally speaking 60Hz High settings is 6GB 1060 or 8GB RX580 territory.
Beyond that, 1070, 1070TI or Vega56.

Titles vary in requirements though, so that's just a solid general guideline.

With some tweaks (say "High" opposed to "Ultra") a 6GB 1060 is more than capable, generally speaking, of 1080p 60-75Hz

 

[swaggycreeper11]

Will i5 8400 gtx 1060 6gb have more than 75fps minimum on fortnite?

 

[Barty1884]

Fortnite, absolutely. Fortnite is relatively easy to run.

It can do >60FPS at 1440p!

https://www.techspot.com/article/1557-fortnite-benchmarks/
Should be in the 90-120FPS range.

 

[swaggycreeper11]

The only thing I have bought for my pc is the i5 8400. So, should I buy the gtx 1060 6gb? Does this sound future proof? I do not generally play games that require a good system.
