Servers are where thread-friendly new architecture shines the brightest

Today, Advanced Micro Devices, Inc. (AMDannounced 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.

AMD performance Opterons

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.

The Opteron 6300's should sell well

AMD's pricing makes the Opteron 6300's (as well as Vishera chippies) a very wise decision that consumers have already responded to with the FX models. It only took Newegg four days to sell out of FX-8350 CPUs and they had a good quantity of them.

Contrary to Jason's comment that AMD's CPUs don't deliver on cost vs. performance, which is total B.S., as Trinity laptop, Trinity desktop and Vishers FX CPUs actually deliver better performance for the same price as Intel's CPUs.

It's time Jason run some real applications instead of tainted benches, so he can get a grasp on reality. Virtually every reputable PC hardware site has noted that Vishera was definitely the better choice on performance vs. price compared to Intel CPUs.

I agree that AMD CPUs are still good for the money, but all intel has to do is lower their prices, which no doubt they are able to do.

"a company = money always matters"
True but AMD CPU also use more power and the more power a CPU "wastes" the more you will spend in cooling, maintenance and what not, on the long run Intel may even be cheaper!

That makes for discussion fodder for internet forum geeks, but quite frankly most businesses don't give two craps about power consumption and cooling.

Where do you get "maintenance" from? You are really asserting that AMD cpu's require more "maintenance" than intel? Do you understand how computers work?

He posts the same crap in every article about CPUs. Ironically trinity/piledriver tend to do much better in synthetics thanks to their ability to saturate all cores constantly. Overall, though, trinity is only dominant in laptops, and piledriver in certain scenarios like cryptography and compiling.

The price vs performance for FX-8350 is controversial. It does well when applications are multi-threaded. Then it does not do well when applications are single threaded. Also it does not show well for power consumption vs its performance. It is hard to tell if this processor has performance vs price compared to Intel. Intel has excellent performance vs price across the board while FX-8350 hits the target sparingly and is scatter-brain for other programs.

The latest Opteron may seem cheaper than Xeon, but only if data centers are still using Opteron systems. If not, switching will be costly, so that $1000 difference will even out to be as costly as Xeon systems. Then there is evil power consumption that data centers have to figure in if going with Opteron is a better buy.

BTW, I see you camping over at dailytech instead of...xbitlabs...or...anandtech.
