28nm mobile GPUs

So I heard a little a while ago on the next generation of 28nm mobile GPUs. Has there been any recent news on them and do you think it's likely that it will use the current MXM standard.

I certainly hope it does.

 

1. The mobile chips, from AMD and Nvidia, aren't coming until we're into Q1 of next year.

2. Whether we see MXM 3.0 carry over or a new 4.0 is unconfirmed, and is solely up to Nvidia, as they own the consortium. We'll probably find out more around the 2012 Consumer Electronics Show.

 

AMD's 28nm Wimbledon GPU Detailed
A Turkish website has detailed the specs of AMD's new 28nm GPU, architecture codenamed Wimbledon. The high-end GPU will use the MXM 3.0 form factor, and should be ready for production in Q2 2012.

The new mobile GPU is 1.4x faster than Blackcomb, which is the fastest Mobility Radeon HD6000 GPU. The Wimbledon comes with 2GB of GDDR5 memory paired with a 256-bit memory interface and, will a TDP of about 65W. This is the last GPU to be used in the Mobility Radeon HD7000 series.

MXM 3.0! If this is true, I'm gonna dance

Mr. Mysterious

 

It would be nice if the next generation cards are kept MXM 3.0, but just remember- even if AMD were to release the 7xxx series as MXM 3.0, they don't control the standard. Nvidia owns the consortium, and may choose to change the MXM standard separate from that announcement.

 

At CES we hope to learn more...

Hopefully like they do with desktop graphics cards, they will come out with some MMX 3 for the older machines that use that standard.

 

yes but it means at the very least I can get some sort of 28nm gpu in my 8150.

 

No, it doesn't at all mean that. The news of AMD's chips being 3.0 came out like 6 months ago, and that wasn't even sourced as an official quote from an AMD employee. Random Turkish website gains exclusive news of that magnitude? I have my doubts.

And In all realness, Nvidia has a vested interest in changing the MXM standard. If they tell the manufacturers that 28nm chips need a new standard, guess what? That's money in Nvidia's bankroll. I mean, they have the entire notebook manufacturing industry in their pockets, because you have to be a paid corporate client just to have access to the standard. It simply makes zero business sense for them to stick with the 3.0 standard. If you ran the company, which decision would the shareholders push you to choose?

I'm not trying to be the dream shatterer, but we need to temper expectations until we get the details through official channels. I for one really hope I'm wrong, and that 3.0 remains the standard through 2012. I don't hold out much hope though.

 

Do new standards actually improve anything, or are they just money-making tools?

 

Usually the new MXM standards keep up with changes in GPU voltage needs, and other things like PCI-Express standard revisions. Now its still up in the air if the MXM standard is changing with the introduction of PCI-E 3.0, don't know yet. However, we are a part of the MXM consortium so as soon as we see a new draft standard appear, we'll let people know, but so far nothing has been published.

 

Bandwidth, voltage, revision... all of these factors play a part. among many others.

What moving to a new standard after 3.0 may bring is not something I'm knowledgeable enough to comment on, partially because we don't even have detailed technical data on the mobile 28nm structure.

The introduction of PCI-E 3.0 is an interesting and important wrinkle I didn't even think about yet. Can the current slot provide the bandwidth needs of an AMD chip which wants.... say 250GB/s?

 

While I agree with the last part of your post, I respectfully disagree with the beginning parts. donanimhaber.com has been around for a while and certainly has a great reputation for releasing good information. Now whether or not the information posted is accurate can't be told until AMD releases any information but to call donanimhaber.com a random website isn't entirely accurate.

I also know that Nvidia owns mxm-sig who controls the mxm standard and as such I would assume, like you, has a say in all things MXM. I would thinks though, it would cost the company a lot of money to switch their mobile gpu manufacturing from MXM 3 to 4 just like all other companies. It may behoove them to keep using MXM 3.0b for a while longer to avoid that cost.

Regardless, I feel that MXM3.0b still has a life ahead of it. The only thing that concerns me is the fact that technology likes to advance regardless of need.

 

Considering I'm holding out on buying a Clevo until next year (waiting for Ivy Bridge and Kepler), I don't really care what version they use, as long as it gains life. If the next revision of GPUs is MXM3, but the revision after that goes MXM4 then I can only stick with one generation. If the format they choose lasts 2 more generations beyond what I use, then I'll be happy because I can do a significant upgrade if need be.
