If you have been looking wishfully at a AMD 3900x the prices are beginning to spend more time within $50 of the MSRP of $499.95(?).

I am also getting notices for ~$150 new 2700x (yes it has the cooler).

What a time to run out of AM4 motherboards :)

Tom


And notices of the 3950x are showing up with significantly lower price premiums.... Maybe by Easter....

But won't Madame Su be launching the 3990wx on Tuesday at CES. Preferably with an option of octo (or whatever) memory channel?

Gamers Nexus has a review of the new Ryzen 5 1600 AF: https://www.youtube.com/watch?v=wRO_AUdmfis, at $85.
Cool...looks like a good economical chip if you just want to just drive gpus!

Other than we know that there are the TRX80 and WRX80 chipsets out there, we haven't heard any rumors yet of actual products employing 8 channels. All speculation so far.

Amd's Eco Mode for the 3000 Series cpus.

https://www.pcgamesn.com/amd/ryzen-cpu-tdp-eco-mode

If the number are right, 50% power reduction giving 70% production that is not a bad trade off.

So can anyone see how to implement this at the Bio's level? Apparently if you can set the maximum TDP profile at the Bio's level you can emulate this "Eco Mode".

And can this be done on a ROG Crosshair VII?

Amazon has the 3900X in stock now at LESS than MSRP.

Yes, it can be done in the BIOS through the Extreme Tweaker menu and the AMD CBS menu. Just set the PPT number to some value less than the 142W that is stock for 105W processors like the 3900X.

Instead, you should adjust PPT (package power tracking). According to AnandTech, this is set by default to 88W for 65W TDP processors, and 142W for 105W TDP processors.

Ryzen 7 4800U benchmarks have surfaced: https://www.userbenchmark.com/UserRun/23316225, FP6, 1 CPU, 8 cores, 16 threads, Base clock 1.8 GHz, turbo 3.65 GHz (avg). Looks like Intel's going to be beat in the Laptop/Notebook market as well.

@ Keith Myers
Thanks for the reply and info.

As for cooling, I have the Noctua NH U14S TR4-SP3 air cooler with two fans,
but bump against the thermal limit during the daytime. Temps here (south
Vietnam) are just too high for it. I guess a 360mm AIO would be my best bet.
Then I can try boosting performance.

And the PPT is hiding under the PBO menu item. And you have to set PBO to manual to see it.

The ASUS search feature for the bios doesn't produce a "hit" for ppt.

This week it's going to happen.
I am going to build the desk on which I will build the new Ryzen system... ;-)

Naaah... I'll put that desk together so I can go build the new Ryzen system. It's time for me to replace my present computer. I think I can be shot down much faster by the irri drones in GRB with a new spiffy system than with the clunker I use now. :-P

When AMD said its 64-core Threadripper 3990X would be ready in 2020, it apparently didn't intend to make people wait very long. The brag-worthy processor is now slated to be available on February 7th for a staggering $3,990 (yes, that matches the model number).

If anyone is feeling generous, feel free to buy me one. Or two, and include a mobo and a few GPUs...

I hope that nobody was shocked by the price. After all, it is commensurate with an Epyc workstation/server processor.

i live in south fl.
the case i had it in with the dual card set up.... made a air pocket with a hs like yours.
even with the 200mm in front the cpu heatsink with the dual fan where so big...... that block a small area of air.
just fyi most aio for tr4 and the new version are made by sub company . from the main aio name. that why all those tr4 aio had issues

You don't have to purchase an AIO using basic Asetek AIO hardware. There are better choices that don't cost that much more than the generic Asetek coolers. You just have look for them at proper water cooling vendors and not the big box stores like Amazon or Newegg.com.
For example the Alphacool Eisbaer 280 AIO with the TR4 mount kit would be a step up from the typical Asetek AIO cooler. If you have to use a AIO, I would steer clear of the Enermax TR4 coolers because they have had multiple and frequent quality control problems with corrosion. But you still need the full coverage cold plate. The only other one I am aware of is the new Coolermaster ML360 TR4 RGB edition that has a full coverage cold plate. Because it is relatively new, it does not have many reviews yet.

Its got me to wondering. If a version 1 EPYC 1 socket cpu with a "workstation" motherboard might do just as good a job running an out-sized load of gpu's? It is clear it would process the cpu tasks slower...

Here is one mobo with Epyc 32 core processor for you. Six slots, three X16 and three X8. Wouldn't be much slower than the Threadrippers.

And its bigger brother at 64 cores.

The membership of the OFA is self-nominated. You can join at any age. But best practice is at least 55 and you can hold off joining until you are 64 where it become "mandatory".
