Just as with MI300A, I am expecting AMD to use fully separate function blocks on the CCD for the interconnect on Halo.
History repeating itself: Zen3 already had TSVs for 3D$ that we only found out about later on.
Zen4 already had the SoIC blocks for MI300A that we only found out about later on.
And Zen5 pretty surely also already has these new blocks as well. The GMI links will be inactive on Halo - at least, that is my educated guess.
You mean to say Zen5 CCD has more than 2 GMI links at the moment and at the same time that AMD won't use them on any product?

I am saying that, as was the case with Zen4 as well, Zen5 has two GMI links for EPYC and standard-Ryzen (only one used) SKUs and additionally has another way of interconnect for Halo. The latter one should be rather small and in some yet unidentified area.

Halo has a separate CCD with a separate TO accounted for.
That'd be a surprise for me - and not in a good way. Somewhere I can hear the benefits of scale scream.
As you seem to have much more insight than me, I am inclined to believe you for the time being - as stated before, I am just speculating.
But I really expected them to put to good use of what they learned with MI300A in that regard.

Any data for 2300 fclk, if it even works? I've heard of some CPUs doing 2233, but not 2300 (non-APU of course).
I tried 4600mts 2300fclk 2300uclk booted to windows but crashesh after 10sec.
Im new to ddr5/am5 ocing so idk what voltages to adjust and whats safe.
4400/2200/2200 1:1:1 also worked but i dont know how to setup the timings had like 70ns+ latency xD
ddr4 4400cl19 xmp settings but no go. aid64 results were interesting. Bandwidth was comparable to 6000mt/s 3:1
But it only worked on agesa 1.2.0.2 non-a. Agesa 1.2.0.2A is currently bugged i get +7-8ns latency on it with exact same settings. Max tuned 57ns settings on 1202a give me 66ns.

I just came from work il try 2233fclk or more.

anyone know true/fake?
This is the original quotation from the yahoo article. It reads like AI generated nonsense.

Advanced Micro Devices, Inc. (NASDAQ:AMD) operates as a semiconductor manufacturer. Latest reports from tech website Smartphone Magazine indicate that the company is planning to enter the smartphone market, and is in talks with phone makers to integrate the Ryzen processors, which are AI-capable, into smart handheld devices. AMD is well-known for powering PCs, but the recent foray of QUALCOMM, a phone-first semi firm, into the PC world, might be one of the reasons behind the AMD move, per the report.

I can't even find the original source "smartphone magazine". The idea that AMD is moving into the smartphone market because Qualcomm stepped into the PC market is ridiculous. This looks like a baseless rumor.

AMD making a smartphone chip is possible, but my question is what do they offer? Their Zen cores are less efficient and have worse software compatibility on Android. Their uncore has way worse efficiency. If they're using stock ARM IP then all they have is GPU and NPU, and neither one is particularly enticing. The one reason I can see for this is the smartphone market is growing and the PC market is shrinking. Moving into the smartphone market makes sense as a long term play if they can establish themselves there.

Kraken bin?
Possible. Previously 8 cores in total (4 + 4 or 3 + 5)

Yet another classic case of WCCFTech not giving a crap about what they scrape from the internet to regurgitate. The authors could read fan fiction from bilibili about their mother potentially buying out Intel and they'd report it without blinking an eye.
