Poll: Ryzen 7950X3D, 7900X3D, 7800X3D

With CES just around the corner the Ryzen 7000 X3D chips are expected to be announced with availability by the end of Jan.

Leaks are suggesting the following options:

• Ryzen 9 7950X3D: 16 MB L2, 192 MB L3, 170W
• Ryzen 9 7900X3D: 12 MB L2, 192 MB L3, 170W
• Ryzen 7 7800X3D: 8 MB L2. 96 MB L3, 170W

The 7900 looks like an absolute stormer here, and likely the chip I will pick up.

192MB L3 cache, absolutely disgusting.

How soon after the announcement do we expect to see them on sale? Would love to be putting an order in for one at the end of Jan.

It was CES > April availability last time iirc, but theres rumors they will have them out end of Jan to buy.

 

[kindai]

Doesn't look like they're going to be mentioned/launched at CES sadly Any new ETA?

Heh? Everything ive seen still suggests CES, has there been something new?

 

[kindai]

AMD keynote in ~3 hours so we will find out for sure shortly after.

The 7900X3D looks like the sweet spot at first glance, cant wait to grab one!

 

[kindai]

The 7950x3d is probably what I would go for, I was impressed by the lower tdp but it seems like they had to reduce it to run the cache?

The higher TDP numbers on the previous chips were pointless, these TDPs are what the chips *should* have been out the gate.

GN did a video on it a while back.

this ? MSI PRO H610M-B DDR4 not sure I would wanna pair anything with this

That is the saddest looking motherboard ive ever seen

 

[kindai]

7800x3d is going to be a monster. No wonder they pushed it back, nobody would buy the 7900x3d or 7950x3d if they all got released together.

 

[kindai]

No reviews for the 7900X3D is pretty odd with a release date of tomorrow?

Its going to be a joke/meme CPU I recon. Basically no point buying it over a 7800x3d and if you can afford a 7900x3d you may as well take the 7950x3d

"The conclusion for this one is no"

Reviews rolling in seem to confirm this is the state of it

Anyone here using a thermal grizzly direct die waterblock and LM on a 7800x3d?

If so, what sort of temps are you idling at and under full load (eg cinebench).

I have PBO at -25 and on cinebnech hitting 75-77 degrees C. So not sure if I should bother with a remount or not.

 

[kindai]

I wouldn’t bother.

This. Most people get temps of 80+ on cinebench.

Even on direct die cooling?

 

[kindai]

What will you gain from it being cooler? What’s your aim?

The main aim is just to ensure its as efficiently set up as possible, and hitting ~80 on cinebench seems a little high when doing direct die cooling.

However looking at @Audioboxer on a 7950x3d a few pages back with the same cooling setup, it does appear that I should probably remount.

 

[kindai]

It appears that was the right call. After removing, cleaning and remounting, dropped 10 degrees off all the temps.

 

[kindai]

So just messing around with some settings.

Enabled Expo: Left everything else on auto.
PBO CO: Set all cores -30. No issues at all stability wise. Not going to mess around with per-core settings.
SOC Voltage: Seemed set at 1.3v default. Should I drop this down?
Disabled integrated graphcis

Cinebench pulling results of ~18300-18400 ish which seems where it should be.

Anything else I should look at in particular?
