Last response: in Reviews comments
The 780G chipset/Radeon HD 3200 and the MCP78S chipset/GeForce 8200 provide the first integrated graphics solutions that can accelerate Blu-ray playback. We dig deep into how well they work with high quality Blu-ray 1080p video playback.

Don't the 780G chips have hybrid technology? It would have been great to see what kind of performance difference it would make to add a discrete card with a 780G chip. Motherboards with integrated graphics cost about the same as those without integrated graphics, and so I would choose an integrated graphics + a discrete graphic card for hybrid performance.

Great article, specially liked the decrypted video benchmarks as I was indeed expecting a much higher difference.
Also was expecting that the single core handled it better as I use a old laptop with pentium M 1500mhz & ATI 9600 as a HTPC and it plays nearly all HD media I trow at it smoothly (Including 1080P) trough ffdshow. Notice the files are usually Matroska or AVI and the codecs vary but usually are H264.
I admit since its an old PC without blueray or HD-DVD I have no idea how the "real deal" would perform, probably as bad or worse as the article says

I have a gigabyte GA-MA78GM-S2H m/b (780G)
I just bought a Samsung LE46A656 TV and I have the following problem:
When I connect the TV with standard VGA (D-SUB) cable,
I can use Full HD (1920 X 1080) correctly.
If I use the HDMI or DVI (with DVI-> HDMI adaptor) I can not use 1920 X 1080 correctly.
The screen has black borders on all sides (about 3cm) and the picture is weird, like the monitor was not driven in its native resolution, but the 1920 X 1080 signal was compressed to the resolution that was visible on my TV.
I also tried my old laptop (also ATI, x700) and had the same problem.
I thought that my TV was defective but then I tried an old NVIDIA card I had and everything worked perfect!!!
Full 1920 X 1080 with my HDMI input (with DVI-> HDMI adaptor).
I don't know if this is a ATI driver problem or a general ATI hardware limitation,
but I WILL NEVER BUY ATI AGAIN.
They claim HDMI with full HD support. Well they are lying!

That's funny, bit-tech had some rather different numbers for HQV tests for the 780g board.

What's going on here? I assume bit-tech tweaked player settings to improve results, and you guys left everything at default?

Guys...I own this Gigabyte board. HDCP works over DVI because that's what I use at home. Albeit I go from DVI from the motherboard to HDMI on the TV (don't ask why, it's just the cable I had). I don't have ANYDVD so, I know that it works.
As for the guy having issues with HDMI with the ATI 3200 onboard, dude, there were some problems with the initial BIOS. Update them, update your drivers and you won't have a problem. My brother has the same board too and he uses HDMI and it works just fine. Noob...

HQV is, unfortunately, somewhat subjective - but I don't know how they could have gotten these scores. Ati told me directly that their low-end cards won't provide any HD enhancements. That was some time ago, and bit-tech aren't a bunch of incompetents, so it's hard to say exactly what's causing the diffrence here.

"In this author’s opinion, motherboard manufacturers would much better serve their customers by offering an HDCP enabled DVI output with a DVI-to-HDMI adapter, instead of HDMI outputs."
Wow. You seem to be REALLY missing the point here. The whole point of this is for HTCPs, and the nice thing about HDMI is that it can send both video and audio to your tv over the cable. If they had a DVI port on the motherboard and you had to use an HDMI adapter, you would have no sound. Doing it the other way around though ensures that people who use it for an HTCP like it is intended get their sound, and those who want to use a monitor buy a DVI adapter. You didn't even seem to mention or test the capabilities of sending audio over HDMI!
I don't complain about my laptop not having a DVI out, and when I want to hook it up to my friends 32" HDTV all I have to do is plug in a simple HDMI cable. If I wanted to run and LCD at home I'd buy an adapter.

I have found that even slow CPUs can playback H.264 AVI files; something's going on when playing back a blu-ray, probably the encryption. I was hoping the AnyDVD HD benchmarks would expose this but that's not what we saw. I'll be digging into it further in a future review for sure.

That is really bizarre... are you sure it works? Have you played back protected Blu-ray or HD DVD's over the DVI cable?
During my testing it didn't work at all, and then when I checked around I was led to understand HDCP wasn't supported on the DVI out of that board.

Well, I'll disagree with you that these boards will ONLY be used for HTPCs, as I've stated I believe that these value-priced boards would be attractive to a whole lot of people with decent monitors who would like HD playback.
As for sound, you can certainly play it back over the integrated sound chip instead of HDMI, so I don't think "you would have no sound." is an accurate discription.

Rumor has it that blu-ray playback relies heavily on the hypertransport speed, and the phenoms do support a higher hypertransport I believe. I'll try to get my hands on a Phenom X3 sample and dig into this question in the future.

There is no multi-channel audio for the 790GX, it was rumoured and even speculated initially, but it never materialized.
The HD4K series has it as mentioned in the review, and for integrated the nV and intel series have added it.
As for those playing BR movies via DVI, wouldn't their playback abaility depend on whether the content flag was enabled or not? Alot of movies don't enable it from what I remember.

I think youttabit's point is that the author is making references that the gigabyte 780G motherboard would make for a good htpc, however his comment regarding a preference for an hdcp enabled dvi port and an included dvi/hdmi adapter doesn't quite jive with that. This is because you'd be losing the ability to send audio over hdmi as dvi carries no audio information. Yes, you could send audio over other cables but that doesn't change the fact that in this sort of setup, your hdmi cable will never have audio information in it. The better option would be to remove the dvi port and include an hdmi/dvi adapter instead.

No, you don't need to download drivers.... you're motherboard came with them on a CD!
Seriously though, you probably have an issue with overscan settings. Go into the catalyst control panel (I am, of course assuming that you have installed the drivers) and look for the section that has the zoom/overscan slider. I can't remember the name of the heading off the top of my head. Slide the control all the way to the right, which should be 0% overscan.
That should fix up your problems with the borders; my GA-MA78GM-S2H mobo did that to me too before I figured it out. I think ATI defaults to this setting because most older TV's overscan (zoom in) the incoming signal. That was due to regulation that a picture had to fill up the entire TV screen - beats me if that's still in effect.

Well, I *am* the author...
And while the 780G is definitely a candidate for an HTPC, it is still a good canditate for a multipurpose PC with HD playback.
Frankly, as I said in the review, if you're a home theater inthusiast you'll be wanting a discrete card with 8-channel audio support and image quality enhancements anyway. The 780G makes for a better multi-purpose PC than it does a dedicated HTPC because of it's limitations, but at least it can playback 1080p with a decent CPU...

Ya, I was wondering about that, it felt like you were writing comments as though you were the author. This is the first time I've posted in Tom's, btw.
I have to add that I really like these sort of articles that appear on tom's hardware. There were a few a while back chronicling different htpc builds (and failures) that I was fascinated by them. They inspired me to build my htpc (which has in turn inspired a few of my friends) based on the 780G which I've been happy with for 6 months now. Although a great piece of media center software which no one seems to mention is Media Portal.

I just recently went through two geforce 8400gs's and both with the cyberlink advisor said that my dvi connection is without hdcp. Be careful if you are going this rout, the cards that I had were from evga. The card said that it was hdcp capable, but it must only be hdcp through the s-video output. Beware if you are buying an 8400gs.

But Cleeve, that's the point. With a native HDMI out on the mobo, you get sound and video. With a native DVI out, you only get video.
Yes you can use a sound card for sound, but that arguement is the same as telling someone to just use another video card for video. The point is that with DVI, you lose the option of sending sound and video together in one cable.
If you can't support HDMI, buy an adapter. But in 2008, it would be hard to argue any advantages of DVI over HDMI.

Splendid article!!!
Very broad testing with affordable today's hardware; something I've been missing from Tomshardware ever it started!
Thumbs up for the review!
Benchmarks done on a 1,8Ghz processor and a 2,4 dualcore is something much closer for me (and other consumers as well) to understand than comparing it to a Quadcore 4x 3Ghz processor. (seeing my current hardware is/was 800Mhz; 1,2Ghz; 2,6Ghz; 2x1,66 Ghz; 2x2,2Ghz,and I have no reference on how fast a 12Ghz processor really is.)
However, I'd like to make some comments/suggestions if Imay.
I would have redone the test using 2XDDR2 sticks (eg: an affordable 2x1GB,or 2x2GB DDR2 memory), since the motherboard supports it, and since on general you have a 20% videoperformance increase, which might just be enough to run 720P or something on the 1,8Ghz.
Also on the DC Athlon benchmarks page it would make more sence to buy the more expensive Athlon X2 5200 $60 processor.
Then downclock it to preserve power, or use AMD's overclocking utilities to dynamically downclock the processor to save energy.
I'm sure the Athlon X2 5200 could run on below 35W if downclocked.
When processingpower is needed, fsb speeds could rise to standards, or to OC mode.
I've successfully watched 720P movies with the VRAM set to only 64MB
32MB gave stutter on my 2x1,66GHz system.
I'm using the Intel GMA945 chipset here, it'd be nice to see a similar Intel graphics chip compared to these 2 from AMD & NVidia.

WaveBossaBut Cleeve, that's the point. With a native HDMI out on the mobo, you get sound and video. With a native DVI out, you only get video.
Not if you had a DVI port that was similar to those found on the back of the HD4K cards, it caries both video and audio.
Really out of the options available, why bother adding the DVI without HDCP at this point in time with the DRM infestation nearing it's peak?
If they were to offer just one or the other fine, but offering both connectors but crippling the one, just seems like foolish oversight.
IMO the best solution for cost and practicality would've been for a single DVI connector at the back with the HDMI AV dongle. It unfortunately does offer something jutting out that could catch compared to a flush HDMI mount, but you'd have all the options from just one connector (HDMI [w/ audio], DVI, VGA, Component). Then if you felt frisky then add another or then the HDMI or DisplayPort.

It's nice to know that the author does care about the readers.
BTW, I mention CnQ because CnQ doesn't work well compare to Intel SpeedStep. The periodic feature of CPU usage might be due to CPU shifting back and forth between 5x and 12.5x multi. Anandtech did some test with 9950 and found that the dynamic CnQ used by Phenom hacks CPU performance a lot, due to threads and processes cycle through cores, and load thread can be passed to dormant cores. Sure way to avoid that is to disable CnQ for the test.

I am confused.
Were the tests done with ANYHD to remove the protection just done in real time, or did you rip the discs and then playback the ripped versions that already had the protection removed?
I would have expected ripped discs (discs ripped to the hard drive, removing the protection altogether) to have a much lower CPU overhead than playback of the originals.
If however, you just played the discs back with ANYHD removing protection on the fly, then of course there would be little difference seen.
Which way was it tested?

Couple of points already mentioned but worth insisting on.
First, HDCP most definitely DOES WORK using the DVI output from the GA-MA78GM-S2H. I have one connected to my Samsung TV with a DVI to HDMI cable and it is fine (no AnyDVD).
Second, it is known that the 780G can perform post-processing at HD screen resolution if it is paired with a Phenom because of the increased memory bandwidth due to HT 3.0. In comparison, it has been shown that the GeForce 8200 shows no improvement with a Phenom.
Finally, the 780G drivers are a bit odd. The post-processing functions available (denoise, sharpen, advanced deinterlacing) depend on the screen resolution, and not on the source video resolution. In other words, when playing a standard 480p DVD on a 1080p screen, there is no post-processing. But when playing a standard DVD with the screen resolution configured to 1024x768, then you get full post-processing.

Both of these video cards have been used in HP laptops recently. The dv9628us uses the GeForce and the new DV7 1000us uses the Radeon. From first hand experience, the Radeon out performs the GeForce hands down. I had so many problems with the GeForce GPU that I had to return the laptop to HP and they sent me a new DV7. The performance on the GeForce card was miserable at best causing at least four blue screens of death a month just playing casual games such as Cosmic Bugs and Luxor. With the new DV7 I have been able to play games like Bioshock and World In Conflict on, with great response. I'm not sure if there is a problem with the GeForce GPU in the dv9628us, HP couldn't find anything wrong with it when I sent it back to them three times. Of course all they did was wipe the hard drive and send it back to me, then called it fixed. After learning about the class action suit that is going on against Nvidia I have my suspicions.

Read this article:
http://anandtech.com/video/showdoc.aspx?i=3411&p=3
And you'll see that although running audio through HDMI over these 2.1 enabled chipsets vs running it through the integrated sound card may not be that big of deal, but in the future as 7.1 becomes standard in integrated solutions it will be a big deal. And I doubt a board that is being marketed for HTPC solutions is going to have a DVI port in place of an HDMI port and lose all that functionality.

I wanted to add that I did like your article and found it informative on video quality and since this article IS about video quality I was a little off mark to come in whining about your HDMI statement.
Historically though I think the progress of technology has favored increased functionality over compatibility and I think I'd be surprised to see these types of boards coming out with DVI rather than HDMI.

Cleeve, I think you did an okay job on the article, thank you for the tip regarding turning on "inverse telecine". I did have the latest driver, but it was not enabled.
I wish I could have seen you tossing in some benchmarks of a PC with a GA-73PVM-S2H motherboard with an Intel Pentium Dual Core 2.0GHz chip since the price is comparable to the AMD offerings. I use this setup for my own HTPC, and it has been working very well. Another "benchmark" I would like to see is a stability test. Which PC can stay on the longest, (have Windows media center set to record TV, antivirus to run once a day, other scheduled tasks, and toss in a DVD to play once a day to simulate normal use). I find my HTPC (which uses Vista as well) usually needs a reboot once every two weeks, and I use it a lot (note: I don't have windows do automatic updates and reboots).
One odd quirk I found with my HTPC when using HDMI for video and audio, if I play a DVD through windows media player, no audio will play unless I go into Control Panel> Sound> Advanced> and then Uncheck "allow applications to take exclusive control of this device". Nero showtime didn't have this issue though.
I look forward to your next article :]

People need to keep in mind that a lot of the things in the HQV test only apply to truly interlaced 1080i material. Either live TV or for poorly telecined films. No material like this will be found on a Blu-ray disk.
Any film frame on a Blu-ray disk has a full 1920x1080 pixels and those should be directly sent to the display without an scaling or interpolation. Jaggies occur on interlaced material when half the missing scan lines are filled in for each field. Complex edge detection is needed to do this without jaggies and only the high powered GFX cores can do that.
So many of the bad scores in the HQV test are only relevant when displaying the output of HD tuner cards showing live TV events. They may also apply to the case where output is scaled to a 30" display.
There would also be problems for low-end solutions if a 1920x1080 frame is stretched to fit a 1920x1200 display. ATI drivers allow 1:1 mapping to prevent this (adds small black bars). (Sending 1080p input into the HDMI port of my BenQ monitor which has no 1:1 option results in completely unwatchable scaling to 1920x1200!)
