AMD Zen Architecture Supports Up to 32 Cores per Socket: Leaked Linux Patch

[alucasa]

Personally, I can use up to only 8 threads. So, if Zen's 8 core CPU beats Skylake by a good margin, I'd switch. Of course, the TDP needs to stay below 95w. I don't want 220w TDP CPU.

I mean, an Intel 8 core is 140w right? I don't know how you expect to get 95w with any sort of speed on 8 cores.

Just remember these are server chips that are 32 cores. They will likely be the same setup as the current AMD server chips where 2 full CPU's share a socket across the HT link. Likely the best you will see in a non-server class is a 16 core chip for HEDT. It will also probably cost a metric shit ton.

HT works okay for me, so 4 core + 4 HT is good and affordable enough for me. At the moment AMD can't beat them with 8 true cores, so that's that.

I did say 8 "threads".

Give it time. Remember single core 2.4ghz athlon 64 was 89w.

Right, but Zen is releasing soon. We can't expect a miracle.

I am hoping the 16c stuff to be 140w chips, but at release it wouldn't surprise me if they were closer to 220w. The 8c stuff had better be around 95w and scale to 140w for quite high clocked units.

Now the other side to this is AMD sucks at first gen parts as of late. Phenom I horribly low clocks, not to mention the TLB bug, then the first gen FX chips performed horribly, I really hope zen doesn't follow this.

Fine. They should be using Linux, anyway.

Yeah like linux is entirely multicore/multithread friendly for enterprises. There are some 3rd party tools which are licensed per core and it doesn't matter if it is real or HT core. Due to this it happens in many cases to run the system with HT disabled as it is cheaper that way.

95watts for 32 cores ,even at14nm that's optimistic check the Tdp on Intel's largest new Xeon would you.

Huh? I said I can use only up to 8 threads. That means either 8 cores or 4 cores with HT. I never said I wanted 32 core cpu for 95w TDP.

No.... These are in 4c modules connected by their internal fabric.
They will include up to 8 of those modules on a chip.

The 32c count is based on combination of knowledge.

We will see which it ends up being. I am still betting its two MCM's

Lol ok... It is not like AMD published the info on the quad core units months ago.

We have some additional details on the 32 core Opteron processor as well. The processor has 4 dies and each die has 8 zen cores.

So if you read what I wrote its multiple MCM's.

 

[xfia]

so its kinda like this?

"Leaked Linux Patch"


Every Linux kernel patch gets leaked and every Linux kernel version gets leaks.
It is called Open-source Software... ohhh and nothing gets leaked, everything is published on public repositories or in public mailing lists.

I'm expecting an mcm but with different asics types

"Leaked" makes people click on news articles.

Lisa Lu announced that we'll see Zen in high perf desktops this year (Q4).
And that there will be many cores.
Which, HOPEFULLY, doesn't hint at single thread performance being too bad, again... =/

Fine. They should be using Linux, anyway.

Enterprise don't run just some random Linux, they run, say, Red Hat or Suse which costs money (although prices are rather modest).

But then there comes stuff such as VMWare, Oracle DB, or WebLogic/WebSphere and those guys charge per core.
Slower cores => money wasted on licenses.
Sadly.

Although it still has its uses.

I'm more that eager to pick Zen up if it is worth on performance grounds. In particular that 32 core monster is drooling object of mine. With Windows limit on accessible cores (72 IIRC) you don't even need dual CPU motherboards anymore.

I only hope that name Zeppelin won't turn into Hindenburg disaster...

Go AMD, at this moment in time I 'm pretty sick and tired of Intel monopoly and doing things how they please.

 

[hat]

I could use a core count like that, but if I could afford it, I wouldn't need it.
