Sharing results

A few weeks back, I wrote about different types of results from benchmarks. HDXPRT 2011′s primary metric is an overall score. One of the challenges of a score, unlike a metric such as minutes of battery life, is that it is hard to interpret without context. Is 157 a good score? The use of a [...]

Looking deeper into results

A few weeks ago, I mentioned some questions we had about graphics performance using HDXPRT 2011 after releasing our results white paper. The issue was that HDXPRT 2011 gave results I had not expected—the integrated graphics outperformed discrete graphics cards. I suspected that this was both because HDXPRT 2011′s lack of 3D work lessens the [...]

Scoring with HDXPRT

Two weeks ago, I began explaining how benchmarks keep score (http://www.hdxprt.com/blog/2011/08/17/keeping-score/). HDXPRT 2011 fundamentally measures the time a PC required to complete a series of tasks, such as editing photos and converting videos from one format to another. It uses the times of three sets of tasks to come up with three use case times [...]

Always wanting to know more

I’m an engineer (computer science) by training, and as a consequence I’m always after more data.  More data means better understanding, which leads to better decision making.  We acquired a lot of data in the course of finishing our white paper on the characteristics of HDXPRT 2011.  Now, of course, I want even more. The [...]

Sneak peak at the HDXPRT 2011 results white paper

After spending weeks testing different configurations with HDXPRT 2011, we are putting the final touches on a white paper detailing the results. I thought I’d give you a sneak peak at some of the things the tests revealed about the characteristics of HDXPRT 2011. As I explained last week, trying to understand the characteristics of [...]

Benchmarking a benchmark

One of the challenges of any benchmark is understanding its characteristics. The goal of a benchmark is to measure performance under a defined set of circumstances. For system-level, application-oriented benchmarks, it isn’t always obvious how individual components in the system influence the overall score. For instance, how does doubling the amount of memory affect the [...]
