Benchmark Results: Media/Encoding

Intel Xeon E5-2600: Doing Damage With Two Eight-Core CPUs
By

Although we typically consider media encoding workloads to be ideal for showing off the benefits of multi-core processors, there’s a limit to these more desktop-oriented applications’ parallelism. MainConcept takes advantage of the physical cores on our Xeon 5500 and 5600 platforms, but still doesn’t fully tax each one. As a result, scaling isn’t particularly aggressive. Moreover, the Core i7-3960X’s improved architecture helps it out-maneuver two Xeon W5580s.

A similar situation transpires in HandBrake, though now the Core i7-3960X also overtakes two Xeon X5680s as well. At least for this type of task, a dual-processor workstation is pretty clearly overkill.

So why the heck would you run Lame, then? We already know this is a single-threaded test (at least when you run one instance of it). For our purposes, we’re really just demonstrating single-core per-clock performance and the impact of Turbo Boost on these flagship processors.

Core i7-3960X spins up to 3.9 GHz with a single core active. Combining the benefits of high frequency with the Sandy Bridge architecture, a first-place finish is no surprise. Xeon E5-2687W, an eight-core beast dissipating up to 150 W, runs at up to 3.8 GHz with one active core. As expected, it falls in just behind the desktop CPU. A max Turbo Boost frequency of 3.6 GHz earns the Xeon X5680 third place.

    Why is it that they never test out games on these CPUs... oh wait.

    When I saw the VS 2010:Google Chrome compilation showing on the graph as 10 seconds to compile I was getting ready to be really impressed ... until the text said 10 minutes. ;o)

    Yea, but how about the Quake frame rate?

    Great review - it covered almost everything related to real workstation workload. These CPUs offer a big performance increase over the previous XEON line, but I'd also wait to see the retail prices before starting building new architecture solutions using this platform.
