Thumbs up AMD RS780 Chipset Released in China

AMD's RS780 integrated graphics chipset was recently released in China. The word is that there are still existing driver issues with respect to CrossFire support. However, all indications seem to confirm one can view HD content without the need for a powerful processor.

Funny how no one tests 1080i MPEG2. After the HD2400 debacle you'd think people would do that.

None of those sites even know about those issues I would wager. Basically no mainstream site knows how to evaluate video processing, some get close, but not quite.

At least these guys ran the HQV test.

I assume that when you sat 1080i MPEG2 you obviously mean content such as CBS HDTV broadcasts.
So if the HD 2400, or 780G, or HD 3450, had problems with 1080i MPEG2, it would have problems displaying it on a 1080P TV correct?

never heard of these guys, but one more 780g mobo, apparently overclocking the IGP to 1GHz and with 64MB sideport mem installed. should be no shortage of mobo options for 780g in a few months

It really sounds great! Gaining acceleration for all video formats at full resolution is a great addition. The 55nm process technology along with PowerPlay will give a very nice power consumption.

Which CPU to choose:
  • Athlon X2 BE-2x00
  • Athlon X2 5000+ Black Edition
  • Phenom 9500

I'm going for the cheapest, lowest power, multicore am2 CPU I could find... which in my case was an x2 3800+ EE SFF on craigslist for $50 (admittedly a steal), TDP of 35w and should run at about 10w during hd playback with the 780G chipset If its not enough, I'll wait for the 65w quad core phenoms (9100e/9150e) and build a low power media server with the x2. I'd go for the be-2400 otherwise... I like to keep things quiet.

Right but the HD HQV test disc is encoded in VC-1 and thus uses UVD.

Yes I mean proper motion adaptive deinterlacing of 1080i sources for video originated content (sports and live events) and proper 3:2 deinterlacing of 24 fps sourced 1080i (basically any primetime drama from NBC or CBS).

I can tell you that you'll want a little but more CPU power then that. I have a really similar build with a socket 939 X2 3800+ and GeForce 8600GT. I would say get one of the BE-2400 edition X2 if you're worried about low TDP (they run at 45W TDP).

There's no way I'd touch a 2400 series when the 3400 series is out and replaces it and is supposedly able to handle 1080i sources better (the 2400 couldn't to save it's life).

That's the whole point of the 780g chipset... integrated UVD2. no discrete card required for HD decoding (we all hope). The only question is, will UVD2 (HD3200) fix what was lacking with the HD2400. I would hope, but only time will tell. Not really worried about power as much as noise, have this unreasonable wish for a completely passive cooled HD HTPC, and this setup should play HD from disk at roughly 30w plus whatever the optical drive draws. Of course, I'll use a media server for the big harddrives... the whole point here would be a very small, very quiet replacement for the old dvd players about the house and could stream HD content from a media server (or elsewhere) as well.

Thanks. I assume the "video originated source" applies to Letterman on CBS, correct?
I have my HDTV hooked up to a 2 year old nVidia 6150 chipset and I do find the interlacing artifacts annoying.

Which players takes advantage of this HW capability?

Yes Letterman is live so it is shot at video rates 1080i/30fps

Any codec that is AVIVO enabled such as Cyberlink's decoder from PowerDVD Ultra. The deinterlacing mode is a setting in ATI's control center.

Thanks. I ordered the Sapphire HD 3450 since that seesm to be the only card avilable in the US right now.

Which CPU to choose:
  • Athlon X2 BE-2x00
  • Athlon X2 5000+ Black Edition
  • Phenom 9500
I'm simply shocked by the performance of 780g... can't believe it! Guess if I'm happy that didnt build my HTPC rig before x-mas now when 780g is reveiled!!

The first benchmark tests with 780g (Hd3200) and bluray/hddvd discs are simply awesome...

Less than 25% average CPU load on H264/MPEG4 AVC bluray disc with ~28 mbps bitrate................................ about the same with VC-1!!!

WITH AN SINGLE CORE ATHLON 3500+ (!!!!!)

Less than 10% CPU load with a X2 5000+ (!!)

Now we're talking....

The BE-2300 I'm planning on for my HTPC rig will work perfectly!!

A friend of mine has the same rig with a 690g board as I plan to build.

Antec Fusion
Scythe Mini Ninja (developed with close co-op between Scythe and Antec especially for the Antec all of you should know)
BE-2300 oc'ed to about 2.1 GHZ
2 x Noctua 1200 mm 800's run on LOW (800 rpm) <8 db per fan (for real!)
No fan on scythe mini ninja, all passively cooled by one of the Noctuas in the Antec fusion side wall.

100% load on CPU for 6 hours resulted in 45 degrees celsius on the CPU!!

Too good to be true. The Gigabyte GA-MA78GM-S2H is the dream HTPC card. 780g+SB700+ALC889 is simply too good to be true!!!

It is released around Cebit show, that is end of Februaru/beginning of March. Simply worth the wait for me..

Then I put a Silverstone nightjar, damp the hdd and optical drive a bit, isolate the chassis etc in my rig and the only fans running will be two 800 rpm Noctuas at <8 db per fan.

DEAD SILENCE anyone??

More info:

Quote:
AMD launched the RS780 and RS740 chipsets on January 23rd. AMD will later launch the chipsets worldwide on March 5th. The RS780 is AMD's next-generation IGP chipset for the performance/mainstream market and supports AM2+ processors, HT 3.0, and PCI Express 2.0. The IGP on the RS780 is the first chipset to support DirectX 10 and Unified Video Decoder (UVD) 2.0 for H.264 and VC-1 decoding. The IGP supports DisplayPort, HDMI, DVI, and HDCP. It also supports Hybrid CrossFireX which will allow a discrete video card and the IGP to work together for increased performance similar to nVidia's Hybrid SLI technology. The RS740 is the value chipset. Motherboards based on the RS780 will cost between $90 and $120. RS740-based motherboards will be around $40 to $60. The RS780 will be known as the AMD 780G chipset and the graphics core known as the ATI Radeon HD 3200. The RS740 will take on the name AMD 740G and the corresponding graphics core known as the ATI Radeon 2100. The ATI Radeon 2100 supports DirectX 9.0, HT 1.0, and PCIe 1.1a. Some motherboards based on the RS780 chipset will be paired with the AMD SB700 southbridge.

Does the 780g accelerate MKVs?

I found two statements:

1. The 1080p .mkv files would be fine. But for Blu-ray/HD-DVD, you should spend more on the CPU, or add in a graphics card (GPU) which provides hardware decoding such as an ATI 2400 or 2600 for example.

2. A French site that I can't understand the translation
http://translate.google.com/translat...%3Den%26sa%3DG

Edit: also found- The IGP on the RS780 is the first chipset to support DirectX 10 and Unified Video Decoder (UVD) 2.0 for H.264 and VC-1 decoding

Is H.264 the same as x264?

Yes.
H264 is the actual standard. X264 is an implementation of a H264 encoder.

The current acceleration for MKV containers has some caveats:

So the results are the same with the rs780 as with ATI cards with UVD2. It depends on the encoding.

So it would be fair to look at the speeds, etc of the 780g chip and compare them to the various ATI 3x00 cards?

any opinions? anyone??? maybe gigabyte cut-n-paste from the 690g manual? according to their 690g mobo manuals, the cpu requirement is the same... seems like an editing oversight to me.

There are several tests on ocworkbench, fudzilla etc if you're looking for reliable high bitrate 1080p playback reviews with CPU load specs.

Here is the one I referred to earlier in this thread... (the one with the single core athlon 3500+)




I'm impressed anyway, and would be very suprised if my BE-2300@2.1 GHZ couldnt handle BD/HDDVD with the new Gigabyte board... are there any reasons it wouldnt handle it???

none that I know of other than the manual's recommended requirements that zzzozzzo posted (x2 4200+). as I mentioned, I'm hoping my x2 3800+ suffices, and think it probably will based on reviews.

@ dougri: you could be right: it could be a Gigabyte "copy/paste job" from another manual

Anyway I doubt it will fully support off-loading of MKV x264 playback, though off-loading might also have something to do with the way (which level etc. ) MKV x264 files are encoded. Also UVD 2.0 might have an edge over 1.0 hopefully.

Looks like a nice mainboard nonetheless, we'll just have to wait and see when it hits the shelves (AFAIK it's not out on the market yet)

PS: you can download the manual from the Gigabyte site

But how good is the GPU when it comes to noice reduction? This is a huge problem for my 2400 card, while the 2600 cards are good according to a test I read some time ago.

Well, looking at the specs of the RS780 ie. the HD3200 gpu inside the features in terms of what you need is more advanced than the HD2x00 based gpu. It's not just faster but technically just as advanced as the HD3x000 series discrete cards.

But I guess we'lll all just have to wait and see. If the RS780 don't meet your demands you could always get a passively cooled ATI Radeon HD3450 to run together with the IGP and use hybrid crossfire.

Allthough coming to picture quality and offloading CPU on bluray/HDDVD disc playback I'm confident we all will be amazed by the results of the 780'

Around Cebit time they claim the Gigabyte card will be available. About three weeks away... Hate waiting!
