As you know by now, HDXPRT 2012 uses real commercial applications and realistic workloads to evaluate PC performance. We believe this approach, where we used the same software you do, and used it to do the same types of work you do, was the best way to relate a PC’s performance to the experience you’ll have.
The point of all this has been to help you answer some of the questions you’d confront when buying a PC. How much of a performance boost does adding memory really give you? Is the faster RAM worth it? How much faster is a new Intel Core i7 processor than a second-generation processor?
This Friday, we’re publishing the HDXPRT 2012 v 1.0 Scaling White Paper, which looks at exactly these issues. To prepare the paper, we took a single system and ran dozens of tests, changing one variable at a time. This let us isolate the effect each component had on performance. We show the effect of changing the following:
• The processor: We compared half a dozen second- and third-generation Intel Core i3, i5, and i7processors.
• The amount of memory: We compared the effect of having 2, 4, 8, and 16 GB of RAM.
• Memory speed and banking: We compared 1,333MHz and 1,600MHz DDR3 RAM. We also looked at the effect of using a single DIMM vs. using two smaller DIMMs for the same total memory amount.
• Drive type: We compared traditional hard disk drives and solid state drives.
Not all workloads reacted the same, so our paper presents the effect of each change on the component scores as well as on the Create HD score. This is the type of information everyone buying a PC needs.
We’re going to have a Webinar at 2 pm ET on Tuesday September 18. We’ll talk about HDXPRT 2012 and take your questions. Details to come.
In addition, we have a new video introducing HDXPRT to system vendors and testers. I hope you enjoy it.
