AMD unimpressed with Intel six shooter As you might expect, Advanced Micro Devices is keeping its chin up amid the ticktocking it's taking from rival Intel in the server space. This week's launch of the six-core "Dunnington" Xeon MP processors - which plug into four-socket and larger machines - made a lot of noise for Intel and its partners, but AMD wants you to be …
If you want to run the most powerful Windows based server then you really need compatible CPU cores like these. However if you base your server on Linux then your choice really opens up. Linux is compiled for pretty much every CPU available. PowerPC for example. CPU's that can be arranged in vastly multi CPU configurations. It always seems to me that the CPU makers have to work a lot harder to make their chips Windows compatible compared to how hard the Linux compilers have to work to support a new CPU.
Effectively with Linux (or Unix) you can simply design the most powerful CPU or cluster forgetting backward compatibility then put Linux on it. With Windows you have to design to the machine code already in existance.
So true. I have read several reports that the typical IT department needs three times as many servers running that other OS as GNU/Linux. One thing these big chips with huge caches will do for GNU/Linux is to allow more users to run on a single GNU/Linux terminal server. With dual-socket-quad-core a fairly large school can run most of the desktops from a single server. That is performance. Hex/octal core chips will be able to do that with a single socket and we can use a second machine for backup for very little cost compared to a bigger cluster of servers.
