Servers are where thread-friendly new architecture shines the brightest

Today, Advanced Micro Devices, Inc. (AMD) announced the Opteron 6300 Series, code-named Abu Dhabi.  Equipped with a Piledriver core, the new chips serve as an enhanced replacement to the Bulldozer-equipped Opteron 6200 Series (which was code-named Interlagos).

As we mentioned in our piece on the consumer Piledriver launch, the new core is impressive, featuring a number of performance enhancements.  However, consumer workloads tend to be lightly threaded, so the consumer workloads tend to fall short on the price-v-performance scale.

In the server market it's a very different tail.  Workloads here tend to be heavily threaded in many cases, such as virtualized infrastructures, web hosting, mobile device data serving, etc.

AMD's numbers may be a bit biased, but it's claiming to essentially match rival Intel Corp.'s (INTC) performance in HPC (high-performance computing) applications, such as chemical simulations, with a chip that's only half the cost.

Intel will likely respond with some aggressive price cuts to stay competitive, but for now it's faced with the puzzle of how to compete with a foe that offers twice as many cores at half the cost.

Unlike the consumer market, Intel and AMD are largely competing on the same node -- 32 nm -- for server chips.  This is because Intel has yet to announce E5 series chips based on Ivy Bridge, having only announced E3 series dual- and quad-core offerings.

We spoke with Michael Detwiler, AMD’s Server Product Marketing Manager, who says that AMD's focus it to be "real targeted, instead of trying to be everything to everybody."

He argues that AMD's new Opterons provide "more computations per dollar" than Intel's mixed 32 nm and 22 nm Xeon line.

The chips feature a number of subtle improvements, including better branch prediction, new instruction set support, and a more efficient cache.  In other words, everything is looking good, although third-party benchmarks weren't available at launch.

Amd chips have always been great for multi threaded. If you care more about multi threads than gaming then Amd is great for the server world and consumer. But they've lost the crown to the very high performance pc. For gaming intel is the best and most enthusiasts and consumers.
But if your in the rendering and content creation Amd offers a very serious second look. I'm totally happy with my amd quad because I don't do much gaming but for rendering and converting movies and everything else, there's been no problem. Especially as things go with virtual machines, Amd is very formidable. It doesn't make sense to compare it as a gaming home pc when your talking about a server article, the requirements and needs are very different. Amd is still just barely hanging on they definitely need to get their act together and produce a better consumer gaming cpu. Their dual cores sell almost as much as their hex cores since they're so good for gaming.
