@GSMD: Yeah the price difference between these chips and a mobile app processor is amazing!

The new Xeon supports 32x PCIe Gen3 lanes, pretty much the standard server interconnect...and of course Intel's proprietary QPI coherent interconnect.

Haven't heard anything about the new interconnect it was working on using all the acquired technology from Cray, Fulcrum and etc. Have you?

Yes, it seems as though Intel is going on the offense in order to not have to be caught in a reactive stance as ARM comes after its dominating market share in servers. This is a real threat to IBM's Power PC and Oracle's SPARC, but those companies could make some sort of move as well since Intel seems to be going after performance while ARM goes after power-saving.

In the log run, Intel is quite focussed

Sometime in the mid-90's, early Pentium Pro days, I went to a talk entitled something to the effect "X86 vs RISC" by Intel Fellow Fred Pollack. He made some interesting observations, one, that it was not totally a technology issue, it was primarily economics. On the technical side he pointed out that even then the RISC architecture was getting more complex. Also, x86 was shedding some of its ISA legacy.

He predicted most x86's architetural rivals would eventually fall, primarily because they would not be able to sufficiently invest in their architectures.

Sounds like Pollack was right. Where is he now?

Extraordinary memory
DrQuine   2/20/2014 7:34:41 AM

The multiple terabytes of memory on these new systems are an extraordinary leap from the largest amount of memory I'd ever heard of before (between 8 gigabytes and 64 gigabytes).  I'd thought that processor address space was limited. How much addressable memory can these new processors support? This certainly will enable big data operations that were not possible before.

I'm not sure how much memory these processors can support, but it is certainly enough for a major push in the big data space. It's an impressive accompllishment from Intel, and one that ups the ante significantly in this market.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
