AMD Said to be Releasing no Less Than Four New Ryzen 5000-Series Chips in March

[AVATARAT]

This rumor about 5800x3d is not good...

AMD Ryzen 7 5800X3D reportedly does not support overclocking (yet?)​

Decided i am replacing cpu in my local proxmox box with a 5600G over the 2600X, I can run it with XFR off 3.9 ghz base clock, and iGPU gives me the second cpu lanes pcie slot for a AHCI card for iommu.

Also looks like I can keep the 2600X cooler, just new compound, so no need to reinstall brackets as better cooler than what comes with 5600G.

Yeah, kinda dumb... No offense to you of course..

They'd need two sets of the 3D cache for the multi CCX chips, which seems unlikely for a first gen of it

Well went ahead and did it, has been a bumpy adventure, not for the faint hearted, with it been a new gen.

A note on the bios for the Asrock B450 Pro 4. I was using 1.50 for my 2600X, I upgraded to 1.80 as instructed on Asrock's site (this the best version for zen+, could see much more options to play with). Then to the latest 3.xx (best version for Zen2), then to 4.80 (earliest version that supports 5xxxG chips). On 4.80 I observed nearly all advanced options on my 2600X vanished, the bios was gutted out, the IOMMU grouping was trashed as ACS was removed, I then installed 5.00 the latest public version and Asrock had added back ACS.

So the first issue was when I removed the cooler, the bracket fell back, as the AMD cooler doesnt secure in place without the heatsink attached. I took the back of the case off (old case) and there is no cut out, so had to drag the board out, put something underneath to hold the bracket up and then was able to reinstall cooler on the 5600G. After that reassembled everything.

After powering up, it was a very long post but successful, I checked the bios and observed a fair chunk of advanced options were back, but still many missing, probably half intact, most of the important ones, however no ACS. I think the G chips dont support ACS, its not official anyway but I found someone on reddit who had contacted Asrock who then told him the G chips dont support ACS. AMD need to publicly disclose this.

I contacted Asrock and pretended to have the USB bug, within a day they sent me a new bios with new AGESA version, it was considerably newer, the public 5.00 has 1.2.0.2, this one is 1.2.0.6 and bios version 5.22.

Still no ACS option however inside was two interesting options called PCIE Alternative Routing. the second one was enumeration. With only the first enabled there was no affect, but after enabling both I now have slightly better IOMMU groups then I had on my 2600X, both cpu routed PCIE slots isolated again. The bios is buggy my second hypervisor boot device isnt visible, on 5.00 it was visible but not selectable as a boot device so buggy on that as well, however luckily all storage devices appear in any booted OS.

The next problem was my NAS VM was crashing on bootup, it worked fine using a generic emulated CPU, after diagnosing each individual new CPU instruction on Zen3, I determined that the PKU instruction is the culprit, seems on BSD guests its not compatible. So I am now emulating an Epyc CPU on BSD guests, and added the missing Zen3 instructions excluding PKU.

I also booted bare metal windows did a cinebench, chip is about 36% higher score vs my 2600X.

The last problem is my monitor a 2209WA has no compatible display type with the onboard outputs, so temporarily I had to keep using the GT 1030, but have ordered a HDMI to DVI-D cable which arrived 5 minutes ago, I will put that in tomorrow.

Hope this helps anyone else who had similar ideas to me for upgrade and use case.

Would they have an Epyc CPU with a 3D cache?

Already announced.

 

[AVATARAT]

So if they can make Epyc with 3D cache, then why wouldn't 5950x3D ?

Because the massive cache will be worth tons of money to HPC and server vendors, while very few people will be willing to pay the astronomical price for a 5950X3D, especially with the likely clock speed deficit compared to the 5950X. Outside of gaming - which doesn't need 12 or 16 cores - the effects of the extra cache on consumer workloads will be very variable, and in some situations not noticeable at all. Milan-X, on the other hand, will pad AMD's margins massively, as there are plenty of cache-sensitive server and HPC applications out there.

Yeah, but last year they showed 3D Cache off with a prototype 5900X. Now they're not releasing what they showed off. Bloody mean tease and frustrating at that.

Interesting. I didn't think a 5600g would be that much more than a 2600x in score?!?!

 

[Mussels]

So if they can make Epyc with 3D cache, then why wouldn't 5950x3D ?

As i said, they wont do it with the FIRST generation of this tech


release a single CCX variant, get all the feedback and make tweaks before going balls to the wall. 5800x3d could run cold, could run hot, could degrade fast... AMD wont know how they work in the wild until the reviews come in, and if the reviews (and then the tech masses) demand a x3D version it will happen, post tweaking

Interesting. I didn't think a 5600g would be that much more than a 2600x in score?!?!

Oh yeah, all the current 5000 series chips are powerhouses

The 5000g are slower than the X, but they're still right up there with the best 3000 series CPU's

Dont suggest that micro center is a viable alternative when the majority of the country isnt even remotely close to a store or doesnt even HAVE a store in their state. You said:

And you got rebuted. for it. Dont get mad when someone counters your argument.

Get mad, over a random stranger on the net? Please, maybe a teenage me would... but this version of myself nah. Don't get bothered because you aren't the vast majority. So unless you've got microcenter money to open more stores, don't get mad at the ones who have access to them.

Hi,
Insane being a key word

Funnier and more typical is Intel releasing 12900ks in front of amd's release lol
