@Hank and others: Good points. We need hard performance numbers. And with no first silicon back yet there could still be significant issues getting a product out.

Well, if you have no hardware to show you send your marketing guys with powerpoint to fight ;-)

Rick,

"There are four families of products under the Thunder brand. One is specifically targeted at servers. Others target storage and security appliances and networking."

 

This is what does not make sense. Volume servers in the datacenter run all those applications today. E.g the same server could run map/reduce (hadoop) and also run generic web-tier applications. It appears that cavium is proposing to fragment the datacenter and have the operators chose between their different offerings and convert volume severs into appliances that can only run specific appliances?? That is a tall order.

Re: 48 core power would be very high

@Servernut: Going back to my notes I see Cavium left itself some quibble room, saying its core "supports optimized OOO."

 


Btw, Rick, what other points in your article are inaccurate "quibbles-room" from Cavium that you are merely repeating? Been reading your articles for sometime and you are usually good about sniffing out marketing FUD.

@Hank, Agree. This is marketing FUD at its best. The silicon is nowhere in sight and will be in production in 2016. It is very easy to make claims with power-point 2 years out.

"Re power, as reported they said the products ranges from 20-95W including the Ethernet ports, so well below Xeon."

 


Really?? Xeon E3 power is in the 40W range, E5 is in the 60W range. Even if you factor in the additional components. How is it lower than Xeon?

 

On the OOO, yes that is a very wide quibble room :) Octeon has in-order multi-issue and to go to OOO is not that easy. I would imagine that is a convinent error on their part.

MIPS and Arm

It may be that MIPS and Arm are geared for different markets, but given that Cavium is making basically the same computer chip with MIPS cores and with Arm cores, it would be interesting to see benchmark results from the two processors.

It would be a real apples-to-apples comparison. Which core is faster?

Until we have throughput/$, throughput/W and similar metrics, we cannot make any useful comparison between product offerings. All we have right now is marketing and PowerPoint.

Reviving hopes for ARM servers
rick merritt   6/3/2014 12:54:22 PM

After the implosion of Calxeda and the rumors about Samsung going off an ARM server project, this initiative just got a badly needed shot of espresso.

But like Linley said, I suspect the real market here starts in 2016, about the time B'com rolls out its part.
