I'm somewhat surprised so many people are surprised that 5800X is hot. It's a 105W TDP part (the max possible on stock on AM4), with a single chiplet. So unlike 5900X and 5950X the TDP is not split between two chiplets, unlike 5600X one chiplet is not limited to 65W TDP. With that added headroom 5800X is bound to be running at the border of the thermal envelope. If people expect/want it to run like the other three chips I'd suggest lowering PPT or use eco mode.
I want to add that the heat is inherent problem of the 7nm process, For example Zen3 in eco mode (65W TDP) will still boost to 5+ GHz and cause temperature spikes. Eco mode is targeting PPT, whereas per core temp could still spike due to a single core boosting to oblivion.
On the bright side, you dont lose ST performance in eco mode, and if the fan noise is bothering you, you can alter the fan speed profile because according to AMD Zen3 should be perfectly fine working around 90 degrees celsius daily.
5800X is particularly very boosty in ST, but since it is not as highly binned as 5950X it uses more voltage to reach the higher speeds and therefore cause higher temperature spikes.
During all core loads, surprise, the temperature actually does not spike. This is my observation so far.
But Zen3 has a much better temperature curve than Zen2 for sure.

Damn! Your RAM is clocking well! I guess you are running 2 sticks?
I made my set of Samsung B-Die stable at 3840MHz CL18-17-16 and the rest of subtimings tweaked, but my best latency was 56.8ns and 56GB/s Read.
Yep! and yes I'm only running 2 sticks. I'm thinking my kit was produced during the crazy high DDR4 pricing and wasn't really binned well, if at all....I wouldn't min

Can your kit do 3600 CL14? With tight timings you could shave off a couple ns's and not lose any bandwidth....Viewing my 3600 CL14 snip a couple posts above for reference.

What kit do you have? The dual rank 32GB one?

Assuming Zen 3 mostly lives up to the expected IPC increases I'll definitely pick up either a 5900X or 5950X and do some shifting around with my current builds. I'll likely pick up an AM4 mini-itx board and push the current 3900X over to it and replace the 6700K.

I doubt it, we'd have probably seen a lot more leaks if so. We can hope for preorders maybe though after the reveal.
If AMD managed to ship Zen 3 products today (or hell even just this week) with wide availability it would be the most impressive thing about this entire launch. Not even Apple is that good at clamping down on leaks, so it would be even more impressive than anything else they might have managed to accomplish.

Earlier this week I found out my main system cannot play 4k video smoothly, so I'm thinking about picking a new system with a non X version comes out.

I've been thinking of building a small form factor PC for a while now. The 5800X would be perfect for this.

I'll probably be looking at slotting a 5800X into my current X570 MB with a 3080-class GPU and a new RAM kit. My current 3600 and RAM will move over to the wife's computer to replace the aging 2500k.

I really wanted to wait for Zen 3 to build my latest computer, but my 4790K system died a third time this spring and I just got fed up and bought a 3900X instead. I still really want a 5900X, and I might just buy it even though it doesn't seem very cost efficient. I'll probably wait until the spring and get one anyway. It'll be the first time I've updated a processor without getting a new MB since I upgraded a Athlon 3500+ to an Athlon X2 4200+.

Yeah I will likely be getting the 5900X, but I will wait for reviews to see which one makes the most sense for games.

Yea idk... def need a new board for anything but also want that sweet RX 6000 series, prob can't swing both. Well, I could but

Didn't watch or read any coverage material but why the skip over 4000?

They skipped the 4000 series because Zen 2 APUs were already labeled as 4000 series parts. This way they get away from the confusion of APUs having last Gen cores on current Gen part numbers.

This needs to be in the board section or build section, but I would like to move to smaller cases, but with great airflow for all components for a great Zen3 build.

I'll post in other places, as my current am4 board is too old for this new goodness. A CPU without a board and bios is useless.

Has anyone said what will be the effective max power draw for any of the announced Vermeer SKUs? Matisse topped out at 142W.

I'm sure someone's said it... just not here. At least that I know of. I'm guessing 125 tho tops +/-

Are there any new motherboards coming out, or revisions? What's my option for an X570 Tomahawk equivalent with Intel LAN?
