It’s all about the hardware!

Perhaps by now, the idea of an HTPC has caught your eye – but what is AMD doing to help things along? This is a fun topic for me, one of my key roles here at AMD is to help define and enable cool new platforms. I get to work with both AMD customers to understand their needs and key AMD partners/industry leaders to enable those new platforms. One of the more recent projects I have worked on is our AMD LIVE! Home Cinema platform, affectionately known as “Maui”.

With this Maui platform, I had the pleasure of working with Intersil’s D2Audio team and MSI to define a unique platform that targets the HTPC space. The goal here was to develop a specification for a platform that focused on the needs of the HTPC space. We wanted to define a platform that would not only deliver an outstanding HD experience, but make it easy to set up and use.

Maui, in reality is the specification MSI used to develop their MSI Media Live Diva platform. What is unique about this platform is that it was purpose built for a specific application.

At the heart of the MSI Media Live Diva platform is our own AMD RS780M chipset. This chipset is a great solution for playing back HD Video content. I am not saying that just because I work here, but because the 780 family chipset supports full HD resolutions including 1080p, 1080i and 720p. It is capable of playing back Blu Ray discs, stutter free. You can even play DirectX 10-level games. To further enhance the video capabilities of this platform, MSI added 128MB of dedicated sideport memory. If you want, here is more information on the 780 series of AMD chipsets.

Now, I know some people are probably thinking, “So, it has great video capabilities, there are other platforms that do that as well.” While this is true, there is more to this platform that just great video…it also has great audio. This is not your typical PC level audio, I am talking about true, AVR class audio. Furthermore, the audio is scalable to meet your needs. MSI offers both a 5-channel amplifier version and/or a 7-channel pre-amplifier version.

5.1 Channel x 100W Amplified Card (MS-4140)

7.1 Channel Pre-Amplifier Card (MS4141)

Yep, that’s right, true AVR class audio in either an amplified or pre amplified format!

So let’s talk about that for a moment. Key factors in overall audio quality are Signal to Noise ratio (SNR) and Total Harmonic Distortion (THD). The higher the SNR and the lower the THD, the better the audio will sound at both low and high volumes (not that any of us listen to our music loud or anything). The audio capabilities of this system are much better than typical PC audio solutions and on par with mainstream AVRs from leading consumer electronics vendors, and I’m not just talking about the low-end AVRs, but their more expensive brothers.

The 5 channel amp card (yes, that is really an amplifier) has a SNR > 105dB and a THD+N factor of < 0.1%. This allows you to connect up to your home stereo speakers directly without needing an expensive amplifier just to get good audio.

Now, that is great if you don’t have a nice amp, but what about the person that has already invested $$ in a nice amplifier? Well, the 7 channel pre amp card has an SNR > 112dB and THD+N factor of < 0.01%. It is capable of driving a very high quality audio signal directly to your amplifier via the multichannel inputs on your AVR.

What about ease of use?

Previously, most HTPC products were based upon traditional, off the shelf PC motherboards. While this is generally not an issue, many of these PC motherboards have legacy PC connections that are just not useful in an HTPC environment. For example, most boards still have PS-2 Keyboard and Mouse connections, some have serial ports and/or parallel printer ports. Many still use 3.5mm audio jacks for their audio connections. These connectors add little value in the Audio/Video (AV) centric environment, which is where the HTPC sits. Now, legacy PC motherboards have gotten a little better over time, they are still not always easy to integrate into your home entertainment stack.

The MSI Media Live Diva on the other hand, has a much more AV centric design. Looking at the back panel for example, you will notice that those legacy PC connections have been replaced by more AV centric connections.

For video connectivity, you have Component Video, VGA and HDMI allowing for connectivity to just about any HDTV screen. For audio, as mentioned, you can drive directly to your speakers or connect to an AVR using standard, RCA cables. No need to find special adapters or expensive cables to try and connect to your other equipment.

Here are just a few thoughts from both reviewers and customers on this platform:

“Overall, I can definitely recommend this platform as Windows Vista media PC platform. It will blow away almost anything else except for perhaps custom gaming machines, and it will be easier to use than most alternatives…Sound quality with this amplifier and motherboard are top notch.” – William Wong, Electronic Design

“For under $1000, System Builders should be able to put together a system that accomplishes everything the AMD Maui PC can do and then some. The platform proves to be an excellent path to a dual purpose system, which could wind up in living rooms and conference rooms alike.” – Frank Ohlhorst, Channel Insider

“Just wanted to pop my head in and say I’ve heard this setup at D2Audio’s offices with some high-end speakers…Absolutely beautiful sound, even at high volumes. And if you want to know my reference, it’s a pair of DT BP 2002s hooked to an Integra 5.9.” – Chris Morley, Morley Digital

“I just built a system with the 5.1 amp card, it will be replacing my Panasonic XR57. I’m still playing around with it, but so far it’s at least equal to the performance of that unit…What really surprised me is how dead quiet this thing is with no signal playing, no hiss, pops, crackles, nothing. Would have never thought this was possible within the confines of a PC.” – Nick Billeci

“I am very excited about this build, it is currently slated to replace the following components
 Integra DTR 7.4 $1200
Toshiba HDA30 HDDVD player $250
Sony BDP300 Bluray $400
Pretty impressive that a sub 200 dollar mobo and amp card can deliver performance rivaling that of the components listed… I am thrilled so far with the results.” – Mark G.

“My initial impression on the quality is “absolutely phenomenal”, both audio and video. This was definitely worth the wait. In fact, I am ordering another one next week.” – William H.

These are just a few of the reviews and comments we have received about this platform, I have personally received similar comments from other reviewer and customers from around the globe. Therefore, as you can see, the MSI Media Live Diva platform really was designed to bring you a powerful HD audio and video experience. If you are interested in getting your hands on one of these platforms, check with your preferred online or local retailer or your preferred system integrator. In fact, next time we will talk more on this topic and discuss the pros/cons of building vs. buying an HTPC.

Till next time, Happy Trails!
