Intel® Atom™ Processor Z670/Z650 and Intel® SM35 Express Chipset-Based Platform Video Decoding Results and Recommendations

June 2012

White Paper Chris Wojslaw Sr. Technical Marketing Engineer Intel Corporation


2

Executive Summary Video decoding performance is essential for an increasing number of

embedded appliances. From digital signage and gaming devices to kiosks,

PDAs, consumer/medical tablets, and point-of-sale devices, the ability to

render smooth high-definition (HD) video playback while preserving low

CPU Utilization is an important factor in component selection.

Intel realizes this and has recently delivered an enhanced media and

graphics embedded platform suitable for decoding any single high-

definition stream comprised of the single-core Intel® Atom™ Processor

Z670 (or Z650) and Intel® SM35 Express Chipset platform (formerly code

named “Oak Trail”). Low CPU Utilization and smooth video playback are

both achieved by using this Intel device combination in conjunction with

Intel’s GMA600 graphics, SM35 chipset, and Atom Z6xx series processor

drivers. Intel has also collaborated with Microsoft – maker of the

Windows* 7 operating system and Windows Media Player* and ecosystem

partners CyberLink* and ArcSoft* – media player creators to ensure the

hardware-accelerated HD video decoding engine inside the Intel Atom

Z6xx series processor is enabled when processing MPEG-2, H.264, WMV9

and VC-1 high-definition content.

This paper presents specific single and dual stream video decoding results

generated from Intel’s Alpine Bay CRB-based Development Kit that

contains the Intel Atom Processor Z670 and Intel SM35 Express Chipset

running Windows 7. Recommendations on what factors influence video

decode performance in this IA-based platform are also included so system

designers can choose the best software applications and third-party

hardware devices to pair with this Intel embedded platform.

Hardware Accelerated Codecs and Recommended Media Players

Four video standards are predominantly used today for HD compression— H.264-AVC (Main and High Profile), MPEG-2, VC-1, and WMV9/WMVHD (VC-1 is very similar to WMV9). Intel’s Atom™ Processor Z670 (or Z650) and Intel® SM35 Express Chipset platform hardware accelerates video content encoded with each of these codecs so long as the production system uses one of the officially supported and tested media players and the Intel GMA600 graphics driver. Three supported and tested players are presently available for this platform – CyberLink’s PowerDVD*10 (PDVD10) and ArcSoft, Inc.’s TotalMedia Theatre 3 (TMT3), and Microsoft’s Windows Media Player 12 (WMP12). Interested customers must contact CyberLink and ArcSoft directly to obtain and license the specific versions of these players cited within this document.

As of Q2 2012, PowerDVD 12 is the only version of CyberLink’s PowerDVD media player suite available for direct retail purchase and downloading. However, a prior generation, PowerDVD 10, is the specific media player that has been optimized by CyberLink and validated by Intel to hardware accelerate video content with the Z6xx series. To obtain and license version 10 of this player, file a request directly with CyberLink at: http://www.CyberLink.com/prog/store/contact-cvlp.do (alternate: https://membership.CyberLink.com/prog/support/cs/customer-services.do ). Cite your need to acquire the PowerDVD10 player version # 10.0.2829.52 recommended by Intel for the Atom Z670/Z650 + SM35 Chipset based platform. Key advantages of this CyberLink PowerDVD 10 media player include:

• Improved optimization for Intel Core and Atom Family Processors delivering smooth playback for high-definition content by leveraging the power of the latest hardware acceleration technology inside the Atom Z6xx series.

• Brilliant Blu-ray 3D, including comprehensive support for various 3D playback hardware, ensures exceptional playback quality for the Blu-ray 3D format.

• Lossless HD audio, including support for HDMI 1.3a, offers pure 8-channel Dolby* TrueHD* and DTS-HD audio via a single cable.

• HD upscaling for DVDs, using CyberLink TrueTheater* HD technology, sharpens the image quality of standard definition content for playback on high-definition TVs and monitors.

• Extensive file format support enables playback of even more movie types, including QT, MOV, RM, RMVB, FLV, MKV, and 3GPP.

• Ambient Light support offers compatibility with hardware featuring the power-saving feature of the latest notebooks, netbooks, and tablets.

Similarly, as of Q2 2012, version 5 is the current version of ArcSoft, Inc. TotalMedia Theatre suite available for retail purchase and downloading. However, version 3 of the TotalMedia Theatre is the application version that has been optimized and validated with the Intel Atom Processor Z6xx family. To obtain and license version 3 of this player go to: http://www.arcsoft.com/en-us/business_inquiry.asp?id=BIZ and file a request specifically to obtain and license TMT3 version 3.0.1.190. Let the vendor know that ArcSoft’s TMT version 3 media player will be installed in an Intel Atom processor Z670/Z650 and Intel SM35 Express Chipset based platform.

Major benefits of this media player include:

• Optimized for Intel Core and some Intel Atom-based HD platforms with Intel HD Graphics so users are able to complete the experience with HBR audio, in a cost-effective way

• Integration of Intel® Media SDK

• Smooth and sharp Blu-ray playback on your PCs with better performance and uncompressed HD sound effects

• Using a single platform, users can experience Blu-ray movies with HBR audio output through HDMI

• Additional audio cards are no longer needed to achieve studio grade audio playback. This cost effective advancement allows system builders and video enthusiasts to build a consumer-like home theater system for all of their high-definition needs.

Important: The decoding engine inside the Intel Atom processor Z6xx series accelerates video content encoded only with the H.264-AVC, MPEG-2, VC-1, and WMV9 (WMVHD) standards. Should high-resolution media be compressed with an On2, DivX, RealVideo10 or other codec not mentioned in this white paper then decoding will still occur but exclusively rely on the Z670/Z650’s Atom processor core for software based video decoding. Codecs not hardware accelerated will bypass the decode engine which will result in higher CPU utilization and increased likelihood of marginal or failed video playback performance (see User Experience Performance on page 17).

Similarly, if a system based on the Atom Z670/Z650 performs media playback with an application other than TMT3, PDVD10, or Windows Media Player 12 then decoding will also be exclusively reliant on the Atom Z6xx’s software-based video decoding capabilities. This will result in much higher CPU Utilization than supported players and sufficient CPU headroom might not be available to service other compute-intensive applications running concurrently.

Atom Z6xx Series Hardware Acceleration Stages

The following block diagram shows the different steps H.264-AVC, MPEG-2, VC-1, and WMV9 compressed HD video content takes as it is demultiplexed, processed, hardware-accelerated, and then rendered by the Intel Atom Z670/Z650.

Figure 1. Atom Z6xx Series Hardware Accelerated Video Decoding Stages

Note: The only native display output from the Z6xx series processor is LVDS.

A second output, HDMI, is also possible with this platform and the SM35 chipset will handle generation of this if necessary. However, besides rendering the HDMI display, the chipset and its driver does not perform a significant role in the video decoding process.

Windows 7 Video Decode Performance

Single Stream and Dual Stream video decode results from the Intel® Atom™ Processor Z670 and Intel® SM35 Express Chipset-based platform under Microsoft Windows 7 are presented in the subsequent sections.

Video Decoding Single Stream Results Using the System Configuration in the previous section, Appendix A contains all single stream video decode results compiled by Intel for the PowerDVD10, TMT3, and Windows Media Player 12 applications.

Figure 2 graphs the most pertinent results from the CyberLink Power DVD 10 media player (version 10.0.2829.52). Because this player activates the hardware video decode engine inside the Atom Z6xx processor, every H.264-AVC, MPEG-2, VC-1, and WMV9 HD video tested yields low average CPU utilization (under 20%) and smooth video playback. Thus, Intel recommends deploying this media player in customer systems based on the Intel® Atom™ Processor Z670 (or Z650) and Intel® SM35 Express Chipset platform.

Likewise, ArcSoft’s TotalMedia Theatre 3 player turns on the decode hardware engine while processing H.264-AVC, MPEG-2, VC-1, and WMV9 HD video. Outstanding playback with no dropped frames combined with low average CPU Utilization (under 20%) is the result illustrated in Figure 3. Consequently, Intel recommends deploying this media player in customer systems based on the Intel® Atom™ Processor Z670 (or Z650) and Intel® SM35 Express Chipset platform.

Results may vary slightly using a newer GMA600 driver version.

8. ArcSoft TotalMedia Theatre 3 (TMT3) ver. 3.0.1.190 is the media player used for all results in this chart

9. Smooth playback occurred for every video test but the 1080p/WMVHD (H.264) clip with the TMT3 player

A third media player tested on Intel’s Alpine Bay CRB under Windows 7 was Microsoft’s Windows Media Player version 12 (WMP12 Version 12.0.7600.16385). As Figure 4 shows, WMP12 turns on the hardware engine while decoding MPEG-2 and VC-1 content and most H.264 AVC-based video. Smooth playback and low CPU percentages are the consistent results. However, high CPU percentages do occur when this media player is processing H.264 Baseline Profile (BP) video in the .avi or .mp4 container format typically found in videoconferencing, mobile, and satellite applications. See the chart region shaded in red and Appendix A for the specifications of the so-called “DSS” 1080p BP content which should be avoided for playback with the WMP12 application if possible. So long as your system does not require frequent decoding of H.264 BP-specific content, WMP12 will deliver similar performance as the aforementioned CyberLink and ArcSoft players. Intel consequently approves use of this player with a system based on the Intel® Atom™ Processor Z670 (or Z650) and Intel® SM35 Express Chipset.

7. Microsoft Windows Media Player 12 (Version 12.0.7600.16385) is the media player used for all results in this chart.

8. Smooth playback occurred for every video test with the WMP12 player.

9. For those areas shaded in red, soft video decoding still yielded smooth playback but CPU percentage too high to service other applications concurrently.

Video Decoding Dual Stream Results Several embedded applications such as digital signage, information kiosks, security systems, and point of sale appliances require smooth playback of two high-definition video streams simultaneously without pegging the processor to >100% utilization. Intel anticipated this use scenario and designed the GMA600 driver and Atom Z6xx processor in such a manner so as to decode two video streams simultaneously with hardware acceleration enabled. Figure 5 below demonstrates that this platform yields excellent dual stream results with the Intel® Atom™ Z670 (or Z650) Processor and Intel® SM35 Express Chipset platform so long as the TMT3 and PowerDVD10 players are both used and the system configuration closely resembles the hardware and software details in the System Test Configuration section.

Appendix B contains all dual stream video decode results compiled by Intel for the PowerDVD10 and TMT3 applications used simultaneously.

Figure 6 illustrates the Testing Setup used for Dual Stream - Dual Display Video Decoding. The graphed results from this test setup are shown in Figure 5.

Figure 6. Testing Setup for Dual Stream / Dual Display Video Decode Testing and Results

As the graph shows, dual stream decoding can be done with this platform so long as the guidelines in this section are followed and the video content is encoded with H.264-AVC, MPEG-2, VC-1, or WMV9.

User Experience Performance Each test’s video playback was evaluated by the tester as Good, Marginal, or Fail.

Single stream performance ratings are listed in Appendix A and dual stream performance ratings are listed in Appendix B.

• The “User Experience” rating was rated as Good if the stream(s) were fully decodable and have no visual artifacts (no green screens, or corruption, etc. on conformance streams), and there are no visible frame drops.

• The “User Experience” rating was deemed “Marginal” if video stream(s) were fully decodable, but with occasional visual artifacts and/or frame


18

drops that still allowed for video playback to be acceptable, per the tester’s discretion.

The term “marginal performance” can be used synonymously with “choppy playback” (defined as fewer than 24 frames/second).

• The “User Experience” rating was deemed “Fail” if video stream(s) were not decodable or the visual artifacts, coloring, or frame loss are unacceptable, per the tester’s discretion. Fail performance is characterized as videos playing back like a slideshow (fewer than 5 frames/second) or Choppy (fewer than 20 frames/second).

Note: No dual or single stream tests conducted with TMT3, PDVD10 or WMP12 fell into the Fail performance level.

Because audio was removed from every video in the test suite, audio playback aberrations (synchronization or pops) were not evaluated with any performance rating.


19

Going Beyond the Platform, OS and Graphics Driver – Other Items That Impact Video Decoding Efficiency

Memory performance plays a large impact on the utilization requirements during video decoding from this Intel platform. Thus, the selection and characteristics of the DDR2-800 memory devices designed into the platform should be strongly considered.

The memory configuration recommended for this platform is 2 GB via 2 Rank x 8 of DDR2-800 (32-bit interface only), memory down only. Alternatively, 1 GB can be used via 1 Rank x 8 or via 2 Rank x 8 but expect slightly higher CPU Utilization percentage with 1 GB total density.

Intel recommends consulting the Technical Advisory titled Intel® Atom™ Processor Z670/Z650 with Intel SM35 Express Chipset-Based Platform Third-Party-Validated DDR2-800 Memory Components (Document #482607; http://edc.intel.com/Link.aspx?id=5347) for recommended DDR2-800 component suppliers.

Other factors playing a modest role in amount of CPU Utilization consumed during video decoding include:

• GMA600 graphics driver version: The CPU percentage changed slightly based on the GMA600 driver version installed in the platform.

• Windows 7 OS type - Primarily Windows 7 Starter, Home Basic and Home Premium are the Windows 7 versions supported by this platform using the GMA600 graphics driver. These OS derivatives yield the lower CPU percentages. Windows 7 Ultimate, and Enterprise are also supported by the Intel GMA600 driver but these are Windows 7 OSes that utilize Aero and thus have some performance limitations. Additional CPU percentages have been observed since Aero has not been a key feature for Intel Atom-based platforms.

• Digital copy protection status of video content: Video encrypted with AACS/HDCP consumes more CPU percentage than without AACS/HDCP

http://edc.intel.com/Link.aspx?id=5347�


20

• Source/Location of Video Content: − Solid State Drives (SSD) will have the fastest transfer rates and

access/seek times and yield the lowest CPU percentage during decoding.

− A hard disk drive is next fastest source/location. − DVD and Blu-ray disc-based and drive content have the slowest data

transfer and data rates comparatively speaking and yield higher CPU percentages.

• Display Resolutions of rendered video during test 1366x768 LVDS and 1280x1024 HDMI had 1% - 5% higher CPU percentages versus lower resolutions.

There was no effect on the CPU Utilization percentages based on the display output type. It mattered little whether HDMI or LVDS was the primary or secondary display. Software factors that had a negligible or no effect on the CPU load during video playback included: version of system BIOS, version of Atom Z6xx driver, I2C driver version of the SM35 chipset.


21

Conclusion Smoothly playing back up to two high-definition videos while preserving plenty of CPU headroom to simultaneously service other applications is clearly achievable with a system based on the Intel® Atom™ Processor Z670 (or Z650) and Intel® SM35 Express Chipset. Just make sure to choose Windows 7 as your operating system along with one or more recommended media players and adopt recommended DDR2-800 memory and other components and storage media as cited in the System Test Configuration.

After creation of a prototype, make sure to perform wide-ranging validation so any slow interfaces or bottlenecks can be diagnosed and solved prior to production.
