Re: Big Skylake X Die Shot & Size Estimate

Another remote possibility has struck me. There has been a rumor of Intel adopting AMD graphics. . As crazy as it would be, POP packaging would be a cheap and easy way to include both a CPU and GPU in a highend socket. The CPU side wouldn't need to be modified as there are 16 PCIe lanes not exposed ...

Re: Panicked Response to AMD Epyc... from Oracle

Oh wait, so that's like 256 thread SMT, and not a 256 thread limit? Nope, Oracle has previously shipped systems with 4096 concurrent threads running. I know that when they reached that figure, they increase the number of concurrent threads to 65,536. That sounds like a lot but they have fabric that...

Re: No Dummy Dies on Threadripper?

Long term I see AMD going the interposer route for their entire line up once real mass production has started. The difference between TR and Epyc is of course the IO which AMD will through in an extra IO die for Epyc. The number of CPU cores is basically limited by the size of the interposer they ca...

Re: Interesting Threadripper story... and nugget!!!

It is entirely plausible that enthusiasts within the company convinced them to come up with a middle ground between the single-die Ryzen and the 4-die Epyc. Whether or not it was a smart business move remains to be seen, but it has certainly stirred things up in the HEDT CPU market. Really wish I h...

Re: Big Skylake X Die Shot & Size Estimate

Pop makes since as the CPU package is used in three different socket packages so far: LGA 2066 with some PCIe and memory channels disabled, LGA 3467 for vanilla Xeons and LGA 3467 for Xeons with Omnipath. The last option is the real driver for pop packing since the bottom package will host the Omnip...

The uncore may not be the same. The HCC and XCC dies have Omnipath options available. The Omnipath controller gets its own PCIe 16x link which remain on package. The number of UPI links on-die may also be different too as the LCC silicon is expected to be used only in dual socket boards where as gol...

Overall, I think they are correct that there isn't a supply side shortage.

Re: Looking for thunderbolt 3 PCIe chassis

The Sonnet Echo Express III looks to be using the effective link speed converted to bytes with overhead removed. It is a very odd way of doing this as that figure is far from guaranteed due to other devices on the chain and if DP is encapsulated alongside PCIe.

With Four dies present and being based on pretty near the same socket as EPYC, the question then remains... could they enable 4-cores on each and have 2-dimms per core for 8 channels of memory? Perhaps in the future and enable more cores? Maybe an upgrade next year with Ryzen 2 or 7nm late in 2018?...
