AMD bails out IT

There's a good deal that's special about AMD's new Shanghai server CPU. It's fabulous science, fun for those of us who get dewy-eyed over the prospect of a 25 percent faster world switch time and immersion lithography. It makes the x86 battle interesting again because it carries AMD into territory that it must fight hard to win--the two-socket (2P) server space--and where innovation is sorely needed. AMD beat Intel's next-generation server architecture to market while closing performance, price, and power efficiency gaps between Core 2 and Shanghai. Just as it did in the old days, AMD now claims that its best outruns Intel's best despite having a lower clock speed.

Your server is wasting your CPU

While using an AMD Barcelona (quad-core Opteron) server to create a portable benchmarking kit for InfoWorld's Test Center, I discovered something unexpected: I could incur variances in some benchmark tests ranging from 10 to 60 per cent through combined manipulation of the server's BIOS settings, BIOS version, compiler flags, and OS release.

AMD sets its sights on laptops

At the logic level, MacBook, the benchmark for success in mainstream notebooks, is unremarkable -- indistinguishable from every PC notebook built on Intel Core 2 and its chipset-integrated graphics. Why, then, can't anyone with the same parts list emulate Apple's growth in an otherwise stagnant notebook market? Because Apple painstakingly hand-optimized its OS for a tiny variety of hardware architectures, presently Intel Core 2, while Microsoft wrote Vista to run on absolutely everything. No PC notebook maker can take the proprietary route that Apple plays to such advantage.

AMD's ready to scale you up

Architectural traits reaching back to Pentium remain present in the Intel-powered servers of today. The limitations of those servers aren't likely to be noticed as long as the routine of IT and commercial server buyers is to add capacity by scaling out, purchasing new two-socket servers. But the time will come when adding a rack server, or a rack of servers, is no longer the wise person's path to increased capacity. Smart planning will lead you to handle bigger workloads without more servers.
