Z390 or Z490? Anyone have a 10th Gen Intel Proc yet?

[hockeyjx 22]

 Has anyone had hands on the Z490 and the 10th gen i7s?  The clock speed is a little lower on the new ones Micro Center has in stock (a 2.9GHz vs i9-9900k @ 3.6). I am on the fence, even with the newer genration.

I was hoping @Jim Roseberry or other folks may shed some light on it for me.

Yep.

Be aware that some Z490 motherboards are active cooled (meaning small high-RPM fan).  

ie: Gigabyte Z490 Vision D (quality board) looks passive-cooled... but there's a fan under the heatsink.

You can hear that tiny fan ramping up with CPU usage.  It's high-pitched and annoying.

 

TDP is 125w (about the edge of large/quality air-cooling).

 

Performance of the 10900k is exactly what you'd expect.

Take the 9900k, add two more cores (four more processing threads) and increase the clock-speed to 5.3GHz.

Fantastic performer.

It'll be extremely popular with many DAW users... (super high clock-speed and 20 processing threads).

Got my eye on the ASUS Z490-A Prime ...https://www.asus.com/us/Motherboards/PRIME-Z490-A/

Sorry of off-topic... I have high-pitch noise from my Z390. Not from fan (I have not found any), but still annoying (from googling that is common). And I wish my TDP 95W CPU consumed that 95W by default. My (middle size) air cooler was unable to keep CPU any cool when I was running my fist PRIME95 test... I was disappointed (by the cooler), till I have found that CPU power consumption is over 200W (with all BIOS "defaults").
I mean it seems like "TDP" has no meaning these days (my 9900K consumes from 10W to 250W at its own will, till limited explicitly).

Can you control RPM of that fan on the BIOS?

and just wondering... Which is better choice 9th i9-9900K or 10th i7-10700K?

That's what I am wondering ....whether to go to a gen 10 i7-10700K, or stick with Gen 9. The prices are really similar, and obviously, the newer gen is more forward-thinking.

The fan can be controlled in the BIOS from what I read on the Asus site.

Depends on the motherboard.

On the mentioned Gigabyte board, there's zero control over the chipset fan.

 

If the motherboard allows, you can set a "silent" profile.

But... when you put the machine under substantial load, that tiny fan is going to ramp-up.

It'll be quiet when idle... but loud when working.

As a test, I loaded a Premier Pro project with a video noise-reduction plugin.

CPU use was ~70%.

Tiny fan was busy/loud/annoying   😉

 

I'd opt for the 9900k vs the 10700k.

Performance wise, it's a toss-up.

9900k has TDP of 95w

10700k has TDP of 125w

When working with large low-RPM fans, it's much easier to mitigate noise.

With small high-RPM fans, it's nigh on impossible to eliminate the noise (while under any significant load).

Threadripper motherboards are a great example.  Sound like you're flying a small model airplane.  😁

I went with the Asus, we'll see how it goes. The one BIG advantage reading up on it was this: it will support both 10th gen and 11th gen processors.

Probably will start building tonight.

I put the machine together. Looking good so far and the benchmarks are solid. Asus dropped a BIOS update today as well, so all good ...not noisy at all (and I haven't put the lid on the Silent Case yet) @Jim Roseberry. Never have problems with Asus setups! Starting to migrate programs at the moment.

Yeah, not all boards are active cooled.  😉

In my example, I needed two Thunderbolt-3 ports.

Asus changed the Thunderbolt header on their Z470 motherboards that have them (including the Prime Z490-A).

IOW, The existing Thunderbolt EX3 won't work.  You need the Thunderbolt EX3-TR (which isn't yet available).

I used to use this app Speed Fan for fan speed noise. It's been many years, so do your homework.

Thoughts?

I will put it through the proper paces this weekend, but so far, it is really quiet. The Asus Fan Xpert seems pretty decent on first test, and I also have a big cooler & fan on it.

Be really careful with the app. If you don't configure it correctly, it could crash you computer.
