Nvidia's Hybrid SLI

[Arun]

Ugh @ http://www.fudzilla.com/index.php?option=com_content&task=view&id=4965&Itemid=1
Hmm given: http://hkepc.com/database/images/20071227122751711517939925.jpg

It isn't clear whether the problem is 750a/780a require a reboot or if that's only the case for 'MCP78' (even though it's the same chip ffs), but either way that's awful. A lot of this better be FUD, otherwise MCP78 is slowly becoming one of the least exciting chipsets in the history of the universe. And that's saying a lot, given some of VIA and SiS' products in the last few years...

 

[AnarchX]

Maybe the logic is to shut down the dedicated card on the fly is to expensive for MCP78 boards?

AFAIK ATi will also only support its "Smart Power" on RS780-M.

 

[Arun]

Logic? What logic? It's at the chip and software levels AFAICT, not at the board level...

So, according to that HKEPC chart, MCP78 has no IGP, but the high-end MCP72 does ?
Something smells fishy to me regarding that data...

Seems that NV will enable Hybrid-Power only on GF9, to give them an exclusive feature over GF8.

 

[Arun]

Hmm - so either 790i has been delayed to Q2, or it has been cancelled, or it reuses MCP55. It doesn't matter which of these three possibilities is the case: either way, that's a pretty major deception in my book. But then again, NV's entire chipset roadmap for the high-end is quite boring either way... Hopefully it'll spice up later this year.

 

[AnarchX]

Looks like 790i will come without IGP:

I'm pretty sure there's an HDMI port in there...
Or is it eSATA ?

 

[AnarchX]

I'm pretty sure there's an HDMI port in there...

But why it is not mentioned or H-SLI mentioned on the description?

 

[NocturnDragon]

I have a question about Hybrid SLI... will it work with two monitors or as common SLI it will turn off all the other video outs?

 

[Blazkowicz]

any idea of the performance of MCP78 with an am2 processor versus am2+ processor? I plan to get it when it's out, but I'll pair it with a sempron LE-1100, not a phenom..

 

[AnarchX]

Seems hSLI will bring us many strange marketing names?

Assuming they'll be consistent in naming these against their G8x-based counterparts (yeah, right... ), the "Geforce 9700" should become the top-version of the mobile G94 (9600), just like the 8700M GT = 8600M GT with higher clocks.

Oh man, does this work recursively?

GeForce 8700 = GF 8600 + GF 8200 = (GF 8500 + GF 8200) + GF 8200 = ((GF 8400 + GF 8200) + GF 8200) + GF 8200.

also the same list formated:

NVIDIA GeForce 9950 (GF 9800 + GF 9300)
NVIDIA GeForce 9850 (GF 9700 + GF 9300)
NVIDIA GeForce 9750 (GF 9600 + GF 9300)

Should it not be a 9700M than?
And fastest G94-Mobile will be 9800M-GTS:

NVIDIA_G94.DEV_0628.1 = "NVIDIA GeForce 9800M GTS"

 

[INKster]

Somehow, i doubt the "M" suffix isn't to be used on any of those on that list.

Also, making a G94 Mobile and then giving it the name "9800M GTS" is very inconsistent, as it will basically render both the -just recently released in actual notebook products on the market- 8800M GTX and 8800M GTS obsolete (if not for performance distancing, then for the smaller G94 core that should be more forgiving on power usage and heat output than the mobile G92).
Where's the sense in that ?

Looks like Hybrid SLi is being delayed until May.

 

[DavidC]

I read numerous postings that integrating the GPU aka Fusion and Nehalem will significantly increase IGP performance. I understand that it will be true for Fusion, because currently, the memory controller is far away from the IGP. But for Intel, the current IGP is right next to the memory controller anyway. What advantage is there for Intel bandwidth/performance wise integrating GPU+CPU?? Only thing I can think of is being able to share the CPU's L2 cache more effectively. Because in bandwidth terms, Havendale(Nehalem with IGP on desktop) will support DC DDR3-1333 and isn't more than G45's DC DDR3-1333.

Someone said that the memory controller will get closer to the IGP. It's not true for Intel!!

Now if it's only Hybrid SLI being delayed, and not MCP79 too, then it's still right on schedule against P45/G45

Someone said that the memory controller will get closer to the IGP. It's not true for Intel!!

Indeed, the only thing you really save on are package/bus costs both in terms of dollars and watts. Both of which are also kinda negligible either way... So the ony REAL effect is lock-in to hurt NVIDIA if OEMs are willing to play that little game...
