Performance

General Performance

As usual, we use Bapco SYSmark 2012 suite to estimate the processor performance in general-purpose tasks. It emulates the usage models in popular office and digital content creation and processing applications. The idea behind this test is fairly simple: it produces a single score characterizing the average computer performance.

The Ivy Bridge is a step forwards in terms of performance, even though a small one. The Core i7-3770K is 4-5% faster than the quad-core Core i7 Sandy Bridge CPUs. The Core i7-3750K is 7-9% ahead of the Core i5-2500K. Besides microarchitecture improvements, this advantage is due to the higher clock rate. The new CPUs feature a more aggressive implementation of the Turbo Boost technology which increases their frequency by 200 rather than 100 MHz at full load.

Let’s take a closer look at the performance scores SYSmark 2012 generates in different usage scenarios. Office Productivity scenario emulates typical office tasks, such as text editing, electronic tables processing, email and Internet surfing. This scenario uses the following applications: ABBYY FineReader Pro 10.0, Adobe Acrobat Pro 9, Adobe Flash Player 10.1, Microsoft Excel 2010, Microsoft Internet Explorer 9, Microsoft Outlook 2010, Microsoft PowerPoint 2010, Microsoft Word 2010 and WinZip Pro 14.5.

Media Creation scenario emulates the creation of a video clip using previously taken digital images and videos. Here they use popular Adobe suites: Photoshop CS5 Extended, Premiere Pro CS5 and After Effects CS5.

Web Development is a scenario emulating web-site designing. It uses the following applications: Adobe Photoshop CS5 Extended, Adobe Premiere Pro CS5, Adobe Dreamweaver CS5, Mozilla Firefox 3.6.8 and Microsoft Internet Explorer 9.

Data/Financial Analysis scenario is devoted to statistical analysis and prediction of market trends performed in Microsoft Excel 2010.

3D Modeling scenario is fully dedicated to 3D objects and rendering of static and dynamic scenes using Adobe Photoshop CS5 Extended, Autodesk 3ds Max 2011, Autodesk AutoCAD 2011 and Google SketchUp Pro 8.

The last scenario called System Management creates backups and installs software and updates. It involves several different versions of Mozilla Firefox Installer and WinZip Pro 14.5.

Take note that the Ivy Bridge CPUs look good at any load and seem to have no weak spots in comparison with the Sandy Bridge series. Well, where could such weak spots spring from? Their execution cores, memory controller and cache memory duplicate the Sandy Bridge microarchitecture with but minor optimizations which are reflected in the performance charts.
