i9-9900K on z370?

[SebastianEier]

I noticed Hardware unboxed showed siginificant worse performance on z370 compared to z390, due to power limits, he did turn them off, but there was still a performance gap.

 

I have pre-ordered the i9-9900K and waiting to install it on my z370 board (sold my i7-8700k) but looks like im going to wait a little while as Intel have stocking issues in Norways retailers.

Hence should i go ahead and try and sell my z370 board to buy the z390?
 

He did say in the video "cheaper"/"lower end" z370 boards, and i have a MSI Z370 Gaming M5, not exactly low end, but not very high end either (180$ now on amazon, 200$ msrp).

 

Is my board good enough to sufficiently power the i9 wtihout bottlenecking it?

 

Thanks in advance

Put a high airflow fan on the VRM heatsinks and remove the rear I/O cover to give VRM maximum cooling, see how that works.

 

Have you updated the BIOS yet?

I've heard the same. I've got a Asus z370 gaming e, and I'm worried that it wont handle a 9900k. I was really wanting to oc to 5 ghz, but if I cant do that on my board I'm going to have to get a z 390. Just sucks because I have a custom hard loop.

You'll probably have to remove all of your power limits and power safe features on the BIOS and try improving the VRM cooling and hope it won't die eventually.

Low end Z370 motherboards won't be ideal for the i9, you can retain most of the performance but the motherboard won't last too long, overclocking also is probably not a good idea.

Well I guess I'll take the power limits off of mine and wait till it fries itself. As long as none of my other components are damaged when that happens.

@Jurrunio @Princess Cadence That is an i9-9900K on Z370 Motherboard..

 

How about i7-9700K on Z370 Motherboard?

I'm wondering how i7-9700K will perform on Z370 board. Also is it worth to upgrade from i7-8700K to i7-9700K on the same Z370 motherboard?

so what, I'm sure you can still find Z390 boards that are more disappointing than the Z370 M5

 

9700k and 8700k should be identical in power draw and performance, I see no reason why Z370 mobo that does overclock the 8700k well won't do it on the 9700k, nor an incentive to buy the 9700k aside from reaching a slightly higher clock.

No & no. There is no point to upgrade a i7 8700k with a i7 9700k.

If you are building a new system you have more choices.

Intel has turned the i7 8700k into a good value. Who would have thought?

I see.. That wont be worth the upgrade is that because 9700k is not a hyperthreading CPU, and worse value than 8700k?

It's just not for those looking performance. Thanks to the larger die, 9700k has lower thermal density, as well as the advantage of being soldered should help it go faster than 8700k in overclocking. The cooling won't as good as the thin silicon 8700k (after using liquid metal under the lid) though due to the need to handle the heat of the solder, so it would be interesting to see how the 9700k overclocks with thee different variables.

[jones177]

Yes.

 

If it had hyperthreading it would be able to compete with the 2700x for productivity. As it is, it only competes with the slightly faster i7 8086k and the slightly slower i7 8700k.

 

Jurrunio mentioned the down side to the i7 8700k. Heat. I did not win the silicon lottery with my i7 8700k so I run it at 4.7ghz on all cores. My i7 8086k is basically a bind 8700k and it runs at 5ghz on all cores with the same temps as the 8700k at 4.7.

In games the 8700k and the 8086k at 5ghz can equal or outperform a i9 9900k. It will be interesting to see what they will do against the i7 9700k at 5ghz.  

 

Check out the temps.

SO, this is my take on it if you should upgrade.

A,  can you sell your i7-8700K for a good price? This is necessary if you don't want the upgrade to cost a lot!
B, do you game or productivity? Gaming i will assume is better at the 97, as it has 2 more real cores, however it has 4 less threads, so productivity will go down.

If you are considering upgrading from the 8700K, i would go to the 9900K as it really is the only one where you gain performance in both aspects, thts why i chose the 9900K, as 8700->9700 would be an upgrade and a downgrade, simply not worth putting money into if you ask me

[Princess Luna]

There is absolutely no reason to replace an i7 8700K for a i7 9700K having gaming as priority, the processor is nearly identical in every way.

 

The hyper-threading evens out the extra 2 cores, it's the same 14nm++ architecture, same cache, the soldered only makes up for the extra cores, overclocking is much the same, most people can only go as high as 5.1ghz on the i7 9700K any ways.

 

The i7 9700K being more expensive it kinda makes no sense, even if you had none I'd still consider the i7 8700K a better purchase for a gaming exclusive rig since it has been shown lower end Z370 motherboards will throttle the new i7 9700K more easily as it stresses the VRM and power delivery further.

I'd be careful making such assumptions. I'm sure it will in general if you take lots of games, 2 threads in general will give 1 core performance. The only issue with this, is that games rarely support more than 8 cores, let alone HT.

I play lots of Prepar3d a flight simulator that plays at times better when HT is turned off, it simply doesn't want to use HyperThreading. Thus I'd take 8 real cores over 6 real cores wtih 6 extra threads for gaming, as you make the assumption that a) it uses HT, which not all games do, lots just use on thread on each core. and b) that the game uses more than 8 threads, as if a game is limited to using 8 threads or less, 8 cores beat 6 cores+2threads any day of the week given no siginificant background applications running.

Hence, i think this limits down the "evens" out scenario is pretty weak.

Having said that, i still, as stated earlier, would discourage the upgrade from 87-97, as it is an upgrade and a downgrade. And i believe the "happier" option is that when you upgrade, you upgrade all aspects of it, which the 99 does.

This I am not aware of, i know about the i9 limitations. Where did you find this concern being raised?

 

In addition to that, I doubt the performance upgrade in games is going to be any significant at all from 87-97, perhaps the gain is even within margin of error, as we are speaking of games that run 6 cores or more, which are quite few and far apart that would benefit from 8 real cores.
