Nehalem: Xeon Gets Core i7 Upgrade

SunGard Adaptiv Analytics v4.0
SunGard Adaptiv Credit Risk application is a component of SunGard's comprehensive suite of risk management products (www.sungard.com). This workload is a scaled down version of the full application. At its core, the application utilizes a proprietary Monte Carlo method financial engine to determine the future value of a fictitious portfolio.

This package consists of a Microsoft Windows based .NET application and two data files - a sample market data and a sample portfolio, which provide input to the financial engine.
I first included SunGard ACR in my Woodcrest preview, and since then I've become a fan of the benchmark. There is nothing quite like a widely used, real-world application that chews through processor cores like SunGard does.



Nehalem turns in yet another win, this time spanking Harpertown by more than 30%

x264 HD Benchmark v2.0
The x264 benchmark is a reproducible measure of how fast your machine can encode a short, HD-quality video clip into a high quality x264 video file. The video encoder (x264.exe) reports a fairly accurate internal benchmark (in frames per second) for each pass of the video encode (Four two-pass encodes) and it also uses multi-core processors very efficiently. All these factors make this an ideal benchmark to compare different processors and systems to each other.
I used to run video encoding benchmarks based on TMPGEnc, but the scaling of the application wasn't spectacular as the number of cores increased past four per system. Needless to say, I was pretty excited when I found a new video encoding workload that scales pretty well to large numbers of threads. While it isn't perfect, the x264 benchmark does a good job of filling up the processor graphs in Task Manager with a combination of encoder and frame server (AVISynth) threads.



Since the test outputs average encoding speeds in frames/second for each pass in the 2-pass encode, I figured that would be the best way to present them. In both passes, higher is better.

Power Useage



The power graph above present s a pretty good visual representation of how the benchmark runs. It does a 2-pass encode four times and averages those times. You can see that the first pass (video analysis) is not as threaded as the second pass (video encoding).
