RV610? That cant be right? The entire Radeon HD 3000 series IGPs were RV610. I thought the Radeon HD 4200 would have a RV620 GPU? Also any word on Hybrid Crossfire?
I think it's right. They use vague terminology to describe it as "derived from" the RV610, so the core silicon itself, as well as the clock speeds, may be tweaked for the better. After all, I'm pretty sure you can squeeze an extra 15% out of the 780G with ease just by boosting the core clock. With proper cooling, those things have a bit of headroom. I would think, given this, that hybrid crossfire would be the same setup as the last generation...

I thought a 'tweaked' RV610 780G already existed, the RV610 based Radeon HD 3300 which from the reviews that I've seen are exactly what you described (a 780G's 3200 with its core clock speed upped)

if you mean HD content, as in MKV files and such - no, you're screwed. there are no codecs out there that can do this yet.
I think you're mistaken: I've been using CUDA decoding via CoreAVC for some time now. It works.

coreAVC is as close as it gets, but it only works on nvidia, and it has some issues. it wont work on interlaced video (aka 1080i) and had some issues with the high quality H264 profiles.

Those will definately be fixed soon enough, but right now - its rather flawed.

Yes, but it does decode most of the stuff I need it to. But yeah, still, the best HTPC is a cheap tri-core or quad-core so you don't have to worry about the GPU not offloading the work....

coreAVC in software mode lets my 4000+ in my media PC do bluray without any issues - and i mean pure bluray disks, ripped to files so they're full 50GB monsters.

I've run into a few really nasty bits of encoding, hence my tri-core/quad-core statement. BR is usually relatively docile. I am no encoding expert, and I don't know what the heck some distros do to their files, but some are nuts.

Memorable is a specific anime movie which loaded my 3.71Ghz Q9650 to nearly 50% load when it was played back. My laptop (2.2Ghz T7500) was unable to play it without stuttering, and my friend's 1.6Ghz laptop turned it into a complete slide show.

There's too many ways to screw up a movie rip. Granted, usually tweaking your settings can achieve smooth playback, but I want to watch movies, not tweak my decoders...

i know.. the IGP in my media PC (same core as this) can clock to 1100MHz (from 500MHz stock) so i'm not surprised they released a model with higher starting clocks.

my microatx rig running dfi lanparty Juniour 790gx M2rs can run clock speeds of 1000 mhz!
Thats a 250 mhz bump if i recall right.
However, my sideport memory cannot do more than 50 mhz bump :S if they made a 64 bit og gDDR5 theese would be Kiiiick ass, and kill off some of the gpu market :p

CoreAVC CUDA is fake, it just uses DXVA

it doesnt. If it did, they'd use DXVA for ATI as well. They've discussed this on their forums a bit.
Its easy enough to know it uses cuda, because you can change driver versions and it breaks - it only works from certain drivers and up, which would not be the case if it used DXVA. It definately lowers CPU usage next to nil, while DXVA doesnt do as well in my testing - its more like an 80% reduction, as opposed to 100%.

handy link where they discuss things DXVA cant do, but they can.
http://support.corecodec.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=92&nav=0,1


the only way to get working DXVA that i've found, is the codec built into windows 7 - but it has issues with some files, at least with the build i have (7127)

The RS880 may be called a part of the HD 4000 series but at the end of the day, the core used is either the RV610 or RV620 GPU core, an improved GPU no doubt but th RV610 is more or less the Radeon HD 2400 PRO and any RV620 based GPU would most likely be comparable to a Radeon HD 3450, either way AMD/ATI has really dominated the IGP market with some of the most capable ones available which is great for people making HTPCs!:toast:

^-- Yeah, I was hoping for more an upgrade with this IGP, preferably something at the 4350 level, so that it can Hybrid with it. Oh well, I'll keep with my current 790GX boards for now, wait for the next series of chipsets.

Rv620

As stated before, this is not a RV610 + 15%. That particular configuration has already been done, it is called the HD3300 IGP. This new chip is based on the RV620 chip. Please also note they are saying the new chip is 15% more powerful than the original RV610 which was the 780G. This means at the same clock speed of 500 Mhz (which I think is what the new chip will start at) the 880G will be as powerful as a 780GX. This should mean the future 880GX should be 15% more powerful than the 780GX.

Sounds good for a back up GPU if yours goes down. I relish the day they throw a 3870 or so on an IGP.
