127 gamers, 1 CPU

I think we'd be hitting up against a LOT of limitations. 64 gamers 1 cpu is probably pushing the max realms of feasibility.

 

Plus I'm sure the other companies don't wanna go through that hell again.

[BigDamn]

Fingers crossed this will be fast enough, might have to dual socket and overclock it

 

 

 

 

 

You're asking if I need it? Hell no. But Cinebench records ain't gonna set themselves!

the dell relationship from what i saw seemed pretty flimsy 

zen 3's design is complete, zen 4 on track yesterday was a good day for amd 

Dell and HPE will be slow with AMD. They're so tied to Intel they can't really rock the boat.

 

However, former AMD CEO Rory Reed just happens to be really high up in Dell right now. So the relationship has improved.

didnt intel just announce copper lake with 56 cores? 2 days ago?

they did, but its still to be seen if it will be used, it has a really high tdp for what it is, though it should be more flexible than the older soldered 56 core cpu as that one was sold to oems as a complete cpu+motherboard kit so there was less choice in where and how to use it.

also did they said when you could actually buy it?

64 gamers one cpu would actually be a single cpu which is much better than using 2 socket system

i dont know just seen it in some news thing and seen it wasnt soldered too

 

i'm sure around same time these epyc cpus but prolly for 20times the price but price really isnt the concern in that area of the market

Epyc.

The Cascade Lake-AP being soldered is about them not being a socketed CPU and BGA-5903, CPU is soldered to the motherboard. You can't just buy those CPUs or select them as an option for a typical server, you have to purchase a specific server made for those limiting your options.

Will this chart from Phoronix emphasizes it even more xP

 

 

And dang if I was the guy buying AMD stock today 4 years ago, every dollar I invested would have multiplied 17 times (i.e. $20 worth of stock then is now $170)! 

 

Intel, Nvidia, and Microsoft for comparison (to be updated later today)

LOL as I expected AMD's marketing is going to take advantage of the continuous stream of security vulnerabilities that Intel Xeons have been found to be vulnerable to. Without directly calling Intel out they are harping on security more than the performance wins.

 

 

lots of stuff such as below on their website.

The CTOs of both Dell and HP were at the presentation pushing Epyc they aren't stupid and you'd have to be stupid to get a high end xeon right now.

Depends, there are a lot of cases where'd you have to while you wait/plan for a more major upgrade. If we wanted to add 2-4 servers to our ESXi cluster EPYC isn't an option. If we are going to replace 20+ then EPYC is an option.

Not to mention that while Zen2 Epyc is definitely a fantastic release, no product is ever a one-size-fits-all solution.

 

On that note, while I'm not surprised to see AMD release a great CPU, I am a little surprised to see Intel giving up ground so readily.  Hopefully we don't see them fall back on their old practices, of trying to trip up AMD through nefarious means.

I don't think they are doing it intentionally.  Just like with Ryzen's initial launch, if they had something to counter up their sleeve they would.

i did some thinking... (uh oh)

 

there're 8c16T parts like the EPYC 7232P. there's also a single 12c24T part that's the EPYC 7272

i kinda want to see the 7232P delidded o_o there has to be only one CCD die in there

(also the possibilities of core counts on TR3K are not limited to CCD groups of 4 now.)

they are probably at least 2 ccds on there, what is the cache of the cpu as that would be the best indicator

doesn't say on wikipedia o_o let me check AMD...

 

EDIT: even AMD's site doesn't specify L2 cache total ._.

EDITx2: wikichip says 512 kb per core, which doesn't say much either. if there're two CCDs would the cache be fused off along with the disabled cores? o_o

Use the L3 cache to get the number of CCDs, each CCD has 32MB cache so that is your boundary point for another CCD. Even if some L3 cache is disabled a SKU with more than 32MB but less than 65MB will have 2 CCDs etc.

 

EPYC 7232P: 8 cores 32MB L3 Cache - 1 CCD

EPYC 7252: 8 cores 64MB L3 Cache - 2 CCD

EPYC 7262: 8 cores 128MB L3 Cache - 4 CCD

EPYC 7552: 48 cores 192MB L3 Cache - 6 CCD

 

From what I can see there are SKUs with 1, 2, 4, 6 and 8 CCDs

 

Edit:

Also yes the L2 cache is exclusive per core so if you disable a core the L2 cache for it is also disabled.

oh so that's what's going on? o_o Was wondering why a few of them had differing L3 cache withing the same core count o_o

 

EDIT: also wow they have CCDs with only 2 cores active o_o kinda wonder if they did this on purpose on the lower end of the chips that had yields better than 2 cores, or there are 2 core yields in the first place

I guess it depends how "cheap" things get. You could still have a seperate wafer design, but just mask/miss out the extra cores, then put them all in the/on the same substrates/backing chips (we only see the stuff the chips are glued to, the die is under that black stuff, what's it again?).

 

But I've no idea if that's what AMD are doing or not. If they are running 1 fab with 1 design and just cutting it up, or running with 2 or 3 skus?

 

PS, also no idea if they do it, but it crossed my mind on if you could recover the outer edge chips too from a wafer this way, turning them into 1 and 2 core chips.

It should be intentional to increase the L3 cache amount on SKUs they want a higher performance or target a workload that benefits from it. The large L3 caches in EPYC2 really helps cut down on certain latencies from not having to go to system memory.
