General Application Performance
SYSMark 2007 is an application benchmark suite that plays back real world usage scenarios in four categories (E-Learning, Video Creation, Productivity and 3D), using the following applications:
Adobe After Effects 7
Adobe Illustrator CS2
Adobe Photoshop CS2
AutoDesk 3ds Max 8
Macromedia Flash 8
Microsoft Excel 2003
Microsoft Outlook 2003
Microsoft PowerPoint 2003
Microsoft Word 2003
Microsoft Project 2003
Microsoft Windows Media Encoder 9 series
Sony Vegas 7
SketchUp 5
WinZip 10.0
Performance is measured in each individual category and then an overall score is reported.
We don't see a huge performance increase thanks to Nehalem, we're looking at an average boost of 7 - 12% at the same clock speed as Penryn. The Core i7-965 managed a 7% performance advantage over the QX9770, while the i7-920 pulled 12% on the identically clocked Q9450.
The biggest performance boost is naturally in the 3D suite, the rest of the applications are showing 5 - 10% performance boosts at the same clock.

"Where Nehalem really succeeds however is in anything involving video encoding or 3D rendering"We have new CPU that does Video encoding and 3D Rendering really well while at the same time the GPU manufacturers are offloading these applications to the GPU.
The CPU Vs GPU debate heats up more.

Wheres the product that offloads encoding to GPUs - all of them, from both makers - as a publicly available product? I havent seen that yet. Of course, we havent seen Core i7 in the wild yet either, but I bet it will be many moons before there is that single encoding suite that is ready for primetime regardless of the card that is sitting in your machine. On the other hand, I can encode my stuff right now with my current Intel or AMD products and will just move them over to the upcoming products without having to think about it.Huge difference. The debate isnt really a debate yet, if you're doing more than just talking about it.

Well if both CPU and GPU are better for video encoding, the better! Even now the rendering takes forever.So there is not any problem if GPU helps allready good 3d render CPU. Everything that gives more speed is just bonus!
