yields

to make a 16 core EPYC you'd need four half dead dies, which are easy to get

to make a 16 core Threadripper you'd need two fully functional dies which are comparably harder to get

 

but then again... there's less silicon for Threadripper so going out of purely material cost it should be more than double the price in material to make EPYC and to trace the interposer

AMD 8 core yields are 80+%. I'm pretty sure that a lot of R5 chips could've easily been 8 cores, their demand must be much higher.

So  even some/most 10/12 core threadrippers will be equipped with fully capable 8 core dies.

AMD is coming back from the dead, and it's beautiful!

And will EPYC be cheap? Nope, both are expensive, because they are server grade parts. And those who buy server CPUs don't really care about price/performance

Cheapest Epyc is between the 400-600 range. Same as the current Intel X99 5930K and 6900K.  I bet you won't find a Skylake-E in that price point.

Now if you do manage to, it will be some slow ass 1.2GHz with no HT and 2MB of shared potato cache. You'll be lucky if that thing even comes in a retail box and gives you a Intel case badge sticker!

 

And just to make it clear, for those who aren't following on CPUs. Price is one thing, cpu tier level is another. Epyc main competitor is not Intel X299, it's Skylake-E. AMD Threadripper is the main competitor to Intel X299.

He kind of already answer that, he sticks to being about 1 gen behind to maintain stability so all the kinks are ironed out before he uses it. (for his editors) he said he would use it on his (possible also luke's) machines at work.

 

I do think their is a market for AMD but it will take time to gain trust and to roll out very stable setups.

Epyc, like any server product, isn't about selling "right now".  It's about client services over the years.  It's going to take AMD a long while to break too far in, but the Zen/Infinity Fabric logic will only keep rolling out.

Yeah, I was mostly talking about the high end stuff. The lower end ones just don't make a lot of sense IMO, I mean, for the same price you will probably be able to get a better Threadripper CPU, so unless you really need 128PCIe lanes or 8 channel memory, they just make no sense....

true, but in a sales perspective you don't want to under cut Epyc with Threadripper.

 

but my point is that it in lines with the rumors of 16c TR starting at $850

I maybe missing something here. 

the lowest tiered EPYC cpu will be >$400. But for roughly about that price, one could buy a ryzen 1800x with better overclocking and lower TDP. 

So I understand that these are server grade chips, what I don't understand is the purpose behind the 8C/16T Epyc cpu. I suppose the 16C/32T threadripper cpu could also fall into the same boat

Why would they build a product that competes with another one of their own products? 

I think I'm missing something here

you are missing the:

and that 8 core EPYC is still EPYC 7000 Processor which will have 8 Channels DDR4 and 128 PCIe Lanes

its simple you wont find servers with the threadripper platform, thats why, if all you need is a gpu farm, they are perfect for that

It's kind of funny if you remember that even the highest end Xeon Golds and Platinums have "only" 6 memory channels and "only" 48 PCIe lanes

(Rumors, but still )

I'm starting to think Threadripper is Epyc

Nah, EPYC has 4 dies and Threadripper has 2

Okay they are the exact same thing just more dies on the Epyc and support for dual sockets vs just single socket on Threadripper.

In that case, 1 Epyc for me please cause Epyc sound more appropriate than threadripper.

back to Phenom days, unlocking the extra cores, imagine... daym....

It was X299. I don't think it's possible to make a mini ITX Threadripper board, I mean, just look at the size of that socket!

NOTE I HAVEN"T MEASURED but it kinda looks like x399 is only a little bit bigger then x299 (if you include mounting hole space.)

maybe up to 10mm wider and a good bit taller. it might be possible. I wanted to overlap them and get some size measurements, but lazy.

 

Spoiler

I would buy an EPYC CPU if they weren't locked

Let's hope that core unlocking becomes possible on Ryzen 5, it would be awesome!

if you ditch the DIMM.2, ditch four DIMM slots, also make them SODIMM, ease up on the VRMs, lose the heatsinks, do some layout optimizations, how big is that chipset underneath you think? I think it's possible to squeeze it in - wouldn't have to trace as many PCIe or memory lanes too.

I mean the X99 and X299 mini ITX boards also consist almost entirely out of the CPU socket

also I bet ASRock can go with some funky custom mounting of the socket like they did with X99 already

 

but what a beaute that board is - with the lights turned off of course...

Do we know wether they are unlocked or not? Because Intel's current Xeons are locked as far as. Of course overclocking doesn't matter for datacenters but it would be nice to see unlocked 32C/64T CPUs.

We know Threadripper will due to it being under the Ryzen name but no news on Epyc. (it is not a "Ryzen" CPU)

They are server CPUs so they are not

If they are unlocked (and reasonably priced) I will probably buy the cheapest one

think about trying to cool 32c at 4Ghz.
