We have produced the following currently publicly available reports for Intel Corp. Reports are listed with the most recent first.
Desktop and notebook system processors: Time and energy savings from upgrading to current models We tested the performance and energy usage of current Intel Core 2 Duo processor-based desktop and notebook systems against that of an older Intel Pentium 4 processor-based desktop system and an older Intel Core Duo processor-based notebook system while running three custom application scenarios.
Intel commissioned PT to conduct a series of tests of servers with their Xeon processor X5570 vs. servers with other Intel and AMD processors shipping at the time of the tests.
Virtualized OLTP performance and power consumption test on multiprocessor Intel- and AMD-based servers We tested servers with the following three processors: AMD Opteron 2384, Intel Xeon X5570, and Intel Xeon E5450. We used Microsoft SQL Server with the DVD Store Version 2 test tool, an open-source simulation of an online e-commerce DVD store. For virtualization, we used Microsoft Windows Server 2008 Hyper-V.
Virtualized Exchange performance and power consumption on multiprocessor Intel- and AMD-based servers We tested servers with the following three processors: AMD Opteron 2384, Intel Xeon X5570, and Intel Xeon E5450. We used Microsoft Exchange Load Simulator (LoadSim), a Microsoft-provided tool for benchmarking an Exchange Mail Server. For virtualization, we used Microsoft Windows Server 2008 Hyper-V.
SPEC CPU2006 SPECfp_rate_base2006 performance and power consumption on multiprocessor Intel- and AMD-based servers We tested servers with the following four processors: AMD Opteron 2384, Intel Xeon X5570, Intel Xeon E5472, and Intel Xeon 5160.
SPEC CPU2006 SPECint_rate_base2006 performance and power consumption on multiprocessor Intel- and AMD-based servers We tested servers with the following four processors: AMD Opteron 2384, Intel Xeon X5570, Intel Xeon E5450, and Intel Xeon 5160.
We conducted a series of studies comparing two types of drives:
- Intel X25-E Extreme SATA solid-state drives (SSDs)
- standard 15K RPM SAS hard disk drives (HDDs)
OLTP performance comparison: Solid-state drives vs. hard disk drives To compare performance and power for online transaction processing (OLTP), we focused on a single scenario: a user needing additional server performance and wanting to know whether six SSDs installed in server drive slots would provide better performance and lower power consumption than a full external 24-disk enclosure of HDDs.
Windows Media Load Simulator performance comparison: Solid-state drives vs. hard disk drives To compare the performance and power when streaming Windows Media, we used the Windows Media Load Simulator, which tests a server’s ability to accommodate a large number of streaming connections from Microsoft’s Windows Media Server.
Photoshop CS4 performance comparison: Solid-state drives vs. hard disk drives To compare performance on visualization tasks, we used a custom test that included four tasks in Adobe Photoshop CS4: opening the Photoshop application, opening an image, rotating the image, and saving the modified image as a PSD file. We ran these tests in both single- and multi-tasking configurations.
Exchange performance comparison: Solid-state drives vs. hard disk drives To compare the performance and power for Microsoft Exchange 2007 storage, we used the Primary Storage performance tests from the Microsoft Exchange Solution Reviewed Program (ESRP) test framework. These tests employ the Microsoft Exchange Server Jetstress tool.
