HDXPRT 4 is here!

We’re excited to announce that HDXPRT 4 is now available to the public! Just like previous versions of HDXPRT, HDXPRT 4 uses trial versions of commercial applications to complete real-world media tasks. The HDXPRT 4 installation package includes installers for some of those programs, such as Audacity and HandBrake. For other programs, such as Adobe Photoshop [...]

An update on HDXPRT development

It’s been a while since we updated the community on HDXPRT development, and we’ve made a lot of progress since then. Here’s a quick summary of where we are and what to expect in the coming months. The benchmark’s official name will be HDXPRT 4, and we’re sticking with the basic plan we outlined in [...]

Keep them coming!

Questions and comments have continued to come in since the Webinar last week. Here are a few of them: How long are results valid? For a reviewer like us, we need to know that we can reuse results for a reasonable length of time. There is a tension between keeping results stable and keeping the [...]

HDXPRT 2012 characterization study

For HDXPRT 2011, we did quite a bit of testing to characterize the benchmark. Those results appeared in an initial white paper and a follow up one. In the first, we ran tests on different processors, various amounts of RAM, internal vs. external graphics, hard disk vs. SSD, and the effects of Intel Turbo Boost [...]

What to do with all the times

HDXPRT, like most other application-based benchmarks, works by timing lots of individual operations. Some other benchmarks just time the entire script. The downside of that approach is that the time includes things that are constant regardless of the speed of the underlying hardware. Some things, like how fast a menu drops down or text scrolls, [...]

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 [...]
