Nvidia 8800 Go or No Go

Found the following article, it was in frensch so threw it in an online translator.. and it came out with this, don't know if anyone thinks it's interesting, i do, and wanted to share the info..


Nvidia: 8600, 8300, but not of 8800 Go?
Nvidia could not launch of GeForce Go 8800, a hypothetical mobile version of GeForce 8800. C ’ is in any case this qu ’ indicates the site VR-Zone. G80 engraved in 90 Nm would produce too much heat well, even after a reduction of the frequencies of operation and voltage, to be able to take just as it is seat within D ’ a portable computer.

Of G84 and G86 mobiles
On the other hand, of the mobile versions of the futures G84 and G86, the G84M and G86M, should be born as of the second quarter 2007, at the same moment or little time after the versions for office computers. Should the top-of-the-range mobile version of G80 for its part N ’ arrive qu ’ at the third quarter 2007 under the name of G81M (GeForce Go 8900?). This last could then N ’ be qu ’ simple a die-shrink of current G80.

8600 Ultra and WP
Let us note finally that this qu ’ it would seem to be photo D ’ GeForce 8600 comes D ’ to appear on Internet. According to the BearEyes site, two models could be born: ultra GeForce 8600 integrating G84 (equipped with 64 processors of flows) given rhythm into 500 MHz and GeForce 8600 WP accomodating G84 (with 48 processors of flows) with 350 MHz. The read-write memory would reach frequencies from respectively 700 and 600 MHz and would use a bus 256 bits.

8300 GS and WP
To replace current GeForce 7300, GeForce 8300 GS and WP should make their appearance. If G86 which animates them would be given rhythm in the two cases with 500 MHz, version GS would not have that 24 processors of flow, against 32 for the version WP. The read-write memory would function on a bus 128 bits and would be given rhythm to 500 or 600 MHz according to models'. Of course, and like always with such information not confirmed by Nvidia, the giant tweezers are required...

Nice post. High end mobile parts always come a good bit later and usually a bit less stacked than their desktop counterparts, usually they start creeping up around the refresh for the desktop versions. Its just the nature of the beast, size and heat will always be a problem with current tech.

 

Interesting, they do not launch a 8800Go but will develop further to 80nm and they launch the 8900Go. I wonder if this is going to work, I mean: a lot of gamers want to see a 8800Go in their 17" (and they want it fast).

I don't think they will bypass the Go 8800 all together. I think they'll die shrink, to 80 nm, after completing many power optimisations, and then label the core a Go 8800. A G81M core is much futher off, and will probably invlove some sort of architectural change.

 

So do you think that would be more of an equivalent to the Go7950GTX or the Go7900GS in performance?

 

Its difficult to say. It largely depends on the concessions made on the core, to reduce power consumption. If nVidia alter the core so much, that most of the brute power of the G80 dissapears, then yes, it won't be massively powerful. However, if they keep some of it, by which I mean a substantial amount, then a Go 8800 should be quite powerful. nVidia will want to aim for something that performs a little faster than the model it replaces. So, for example, a Go 8800 GS, may perform a little faster than the Go 7900 GS.

 

Interestingly, there's mention of a Go8600 Ultra. Looking at the speculated core and memory speeds, with memory bus at 256-bit, it could be on par with today's Go7800/7900GS. Imagine that power in a 15.4" form factor.

 

I'm looking foward to getting a 8600/8500 in a 15.4" form.

How effecient can they make these beasts? A current 8800GTX eats more power than most desktops, how will they cram it into a mobile form factor while retaining it's identidy?

 

If they base the Go 8600 on a G80 core, then it will be very large and quite hot. However, nVidia will probably design a new core which doesn't include all of the 128 stream processors the current G80 has. Instead, they may limit the core to something like 36 or some number around that. Its difficult to say what exactly. Also, it is almost certain that they will build the new core on an 80 nm process, as a 90 nm process will make the card quite warm and inefficient.

A Go 8800 should be based on a G80 core, as that is the one that has all the tweaks and the raw power that makes a fast core. Its likely that nVidia will die shrink that too, because it will get quite hot. Other power optimisations will be made, and they should help the card become very fast. However, I wouldn't expect something like the Go 8800 to perform blisteringly fast. Also, nVidia may cut the memory bus from the current 384-bit, to a simpler 256-bit. This is to save cost and also the reduce the size of the card.

 

Just to ad some info to the whole Go 8*** series story...

TehStranger posted this link about a week ago (so the credit for it goes to him ) but that was in the "what notebook should i buy" section, and is maybe a bit hard to spot there. Thats why i also posted it here.

 

Thanks for the credit, MGW. Your link is getting 404 error though, so here's the proper link:

Hey that is interesting, looks like the Go8600 is up and running, I think I will get a comp when that comes out. AND I AM NOT WAITING ANY LONGER

 

You're welcome

Strange, the link looks the same to me... but thanks for re-posting

I was looking @ a G1, but since DX10 (wich is the future) and it now looking like there is an estimated time for a proper mobile DX10 GPU. Maybe i'm also gonna wait for a Go 8600 in a 15.4" notebook
