Discussion Zen 5 Speculation (EPYC Turin and Strix Point/Granite Ridge - Ryzen 9000)

[DisEnchantment]

Speculate at will

 

[Tuna-Fish]

Has it been confirmed to be single CCX?

That's a much more important detail than exact amount of c and non-c cores.

Well AMD doesn't have 5c ring configs so it should be uniccx.

 

[gdansk]

probably higher MT in TDP limited cases if anything

Nope. It is lower. Zen 5c and Zen 4c are less efficient at the same wattage as their counterparts on the same process. They are clocked much lower to make up for that.

Zen 5c and Zen 4c are less efficient at the same wattage as their counterparts on the same process.

Not really. They're a tad bit more efficient at 1w but it also depends on how much LLC they can access.

C cores are more efficient up to a given power, say 2.5-3W/core, this can be deducted easily from the 7545U power/perf curve vs the 7540U, you can draw the parralel with Strix Point wich has exactly 2 x the core count and same repartition than the 7545U and get why it was preferably used at 28-30W.

They're worse per AMD's own statements at ISSCC 2024.
But that doesn't stop them from being cheap. Throw away the PP for the A.
AMD just can't do 4+4 like everyone else. They gotta cheap out. Edit: even after they already cheaped out by using last year's process.

Pretty sure that wasn't iso $$.

It was the same total cache, less cache per core. But in a 1T test like that it is the same.

 

[Ackmed]

Finally pulled the trigger on a 9800X3D. Amazon has it on sale for $450 right now. Refused to pay price gouging.

Who was the seller? It's a suspiciously low price.

ships from and sold by (no, thats not a typo)

One may always pick different sellers so I am curious to see who Ackmed bought from. But I suspect it is something like that...

thats on the main page, not alternate sellers.

I am aware... but that does not in anyway tell me who Ackmed bought from for reasons I just outlined.

Geekbench says 2 clusters of 4 cores, very likely dual CCX.

**EDIT - nope, look at the seller. lol Sold by "wuhanshisaihejianshangm"

I wouldnt go near that one. Its like the $319 9900X I posted from Amazon the other day..

I was trying to get Ackmed to look at his order and realize it's not a real seller. But Mark kept answering for him. Oh well... maybe being straight to the point works just as well.

I guess I don't understand. The URL is amazon, how could it be a fraud ??

It needs to say shipped and sold by Amazon.com to be completely legit. Amazon is a drop shipper in the case of your deal post.

Is this a rare joke? It's a waste of time. You'll get your money back when they fail to deliver but why waste time when Amazon was in fact selling them earlier for not much more.

Was planning to preorder the HP Z2 Mini G1A, and when inspecting the CPU specs I can't seem to find any mention of any MALL at all in AMD website. Is it website issue or this is also another case of those +32% Z5 IPC bamboozle.

They never bother listing caches for iGPUs.

LNL has the battery life lead aka what matters.

I mostly agree, but if you're going to use the GPU at all not having to deal with Intel's graphics drivers matters quite a bit also.

Indeed. But, again, LNL is a good SOC. Just pricey.
