Questions tagged [xeon]

The Xeon is a brand of multiprocessing- or multi-socket-capable x86 microprocessors from Intel Corporation targeted at the non-consumer server, workstation and embedded system markets.

The Xeon brand has been maintained over several generations of x86 and x86-64 processors. Older models added the Xeon moniker to the end of the name of their corresponding desktop processor, but more recent models used the name Xeon on its own. The Xeon CPUs generally have more cache than their desktop counterparts in addition to multiprocessing capabilities.

is it dangerous for the processor core to be *always* loaded at 100%?

In my HFT software I plan to use one core for stock index calculation. That would be simply while(true) loop without any delays which will calculate (sum and multiply) components as often as possible (so millions times per second) and I plan to do…

What is the difference between the C0 and E0 stepping in the Intel Xeon 5400 family of processors?

My primary question is in the title, and can be answered as simply as that. However, I think some background information may be relevant. I'm doing some research into upgrading one of our three year old Dell PE 1950's to be a heavyweight (for a 1U)…
