ATI RS780 benchmarks

It seems like there's some headroom on the graphics core clocks...!

Nice results... Looks like I can be comfortable making a HTPC using this board.

That was with the stock heatsink WITHOUT FAN. Wow.

The PConline article linked to earlier seems to indicate that the MCP78 used was MCP78U, which was NVIDIA's higher speed graphics engine. According to HKEPC we may not have seen the highest verion of RS780 as whats been tested so far is 780G, but is looks like there could be a 790GX based on RS780, with higher IGP performance -

I see the big difference is Crossfire X support which says to me that it would be used in boards that would sport multiple video cards. But since we know that Hybrid Crossfire really only works when you have low end video cards, it is more than likely targeted when Crossfire X supports turning off the video cards and using the IGP.

That means for me and my next project, my HTPC, it's not a cost effective option as the motherboard that has to support multiple video cards is got to be more expensive. Unless some board manufacturers utilize that IGP on some normal boards for speedup.

I guess we have to wait and see when it gets announced and boards shown.

Has anyone found out which cards support hybrid xfire? And are there any benchmarks of it?

Also can you get hybrid xfire on an intel board?

Thanks.

 

[Valzic]

I don't think they have specified yet which card will work or not but AMD has said they will to prevent someone bying a 3870 and expecting it to better the performance.

This was a preview.

Hybrid xfire will not work with Intel becasue there is no ATI IGP for intel anymore. If you recall ATI got bought by AMD and their Intel chipsets went away. (at least the new ones)

 

[Squilliam]

I was hoping to save the 100+ watts idle of a 3870x2 with hybrid xfire. But hey, if it only works with amd it's actually a compelling reason to get a Phenom instead.

 

[Valzic]

nVidia has their version which adds to whatever nVidia card you get.

But who knows what the final drivers will be. Maybe AMD will alter theirs to do the same. However the idea that you use your IGP and turn off your main video card is appealing. Especially since most stuff on PC for me is non-gaming. Forum hopping, internet browsing and programming work. It would be nice to use less power during that but bump up when the old video card is actually required.

This RS780G is simply a revolution in IGP market:

Review RS780 + RD790 + NF590
This model has 64Mb of sideport memory + HD 3200 + SB 700

Media Encoding Performance:

HDD:

With the overclocking capabilities that this chi7 offers easly it breaks an HD 2400Pro, and this is not even the top model because it only has HD 3200 in it.
The Top model -> RS780D will have an HD 3300 IGP and sideport from 64Mb to 128Mb.

Ugh, nVidia PLEASE match or exceed this. Why did AMD have to make their IGP's platform specific... sigh.

 

[DavidC]

Holy crap, I never expected the IGP to be this fast. And this isn't even the highest one!! There will be RS780D, wow!! IGP that exceeds 8400GS discrete graphics and can be overclocked by 2x with same passive heatsink. It's 3-4x faster than any IGP out there now. What are they trying to do?? Replace their entire low-end with IGP??

It makes a compelling offering for anyone wanting to build a low end system now doesn't it? Hybrid Xfire for the low end gamer, and since most people don't ever use the full capacity of their CPU before they toss the system the IGP makes sense.

I can see a lot of OEM design wins over this.

Go AMD!

What they're trying to do is give OEMs a reason to buy their processors, since they haven't been able to sell as many as they would like at high enough prices ever since the Core 2 came out.

And it's working perfectly in China.

If these results prove consistant across the globe, makes me wonder what Fusion will do.

What's this hybrid crossfire that you guys are talking about? Are you saying I can use this integrated card and crossfire it with another "normal" ATI video card or something else entirely?

Just the low end ones like the 3400 and 3200 series. Not sure about the 3600 series. It's gonna be a boon for people building 500-800$ gaming/Home Theatre Pc's

Anyone have any idea when these motherboards will hit UK shelves?
Looks very tempting...

The Gigabyte GA-MA78GM-S2H seems to be close to hitting retail, but the downside is that that board has no seperate Pool of Memory for the IGP. I think the performance will be horrible in that case.

 

[Valzic]

I suspect the first bunch of boards to be released will not have the memory. But I suspect a few weeks later we will see those. Makes sense from a business point of view. Most sales targeted to OEM and we who want the extra speed of the built on memory and are willing to pay a bit extra, are in the minority.

I will wait patiently for those before I jump in.

Guys the sideport memory bank is not for performance. It's more of a power saving measure so that you don't need to keep the CPU active when you want to write to VRAM. The sideport buses are usually 16-32bit, just enough to provide the most basic functionality.

Sure, but most benchmarks measure a >15% advantage for the sideport-memory and imo the most people would use 780G with a HT1.0 CPU at the moment.
