Looks like a study in contrasts - the Power7 designers continuing to go after the highest speed - 5+ GHz, 80MB caches, the AppliedMicro designers going after integration, efficiency and right sizing and Intel doing what it does best - leading edge fabs that give it the advantage. It appears that all three are targeting different segments of the server market. Oh and Pat comes across as a petty partisan. Maybe he should run for political office.

Good to see that Oracle is continuing the Sparc line though there were fears of it's imminent demise. Sparc lost the battle for supremacy a decade back which made it easy for X86 to proliferate but these new chips could bring about some refreshing change in server market. How low can they make a server to own while still providing the reliability and throughput is the question.

The Core is a tiny portion of any Server, so "which core ?" is asking the wrong question. More important are GB/s/watt numbers, and longevity and process. Servers is a simple numbers game, there is no marketing sizzle, or packaging design froth. That means the big players, with strong FAB backup, will continue to be the main forces here. It is also why highly focused solutions, like IBMs, can find a place.

Rick, can you share more details on IBM POWER 7+ please. I know that you attended HC24.

Feeling guilty I added a page with two foils on Xeon and its new power saving technology.

OK, so I did not say anything about the long, detailed Intel Xeon presentation, but I figured it's been shipping awhile and people know about it already.

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.
