Why would AMD choose not to use the same measuring technique instead of making themselves look worse if that was the case? Or atleast make it more publicly known so they could be compared on a even playing field.

I don't know, could be a lot of things really. Intel making up their own as they see fit. Just because one car company decides to call a 3/4 mile a Dile and start advertising they get 45 DPG doesn't mean everyone thinks it is a good idea to create their own standard of metrics. Does make one wonder why there isn't a standard or why it isn't enforced?

Had to rep you on that. But for those wondering about Intel skewing the numbers, I believe it was discussed in here. It is real. I forget who did point it out. I would search and quote the posts, but it's time for bed for me.

AMD used SDP on one of their recent roadmaps.

They started doing that with Mullins and Beema though.

TDP for Mullins is 4.5W and is considered to be a Fanless APU. edit: For Tablets, it isn't fanless enough to be for phones which require SDP to be in ~1000mW area.

28nm SHP returns...

I had a thread DEDICATED for this.

I reinstate 28nm FDSOI is most likely 28nm SHP.

AMD's golden age has started.
Just think of it, APU's having performance way better than the i5's, HSA on the APU (CPU+iGPU), Mantle on the GPU and the best part: HSA and Mantle working together via Hybrid CrossfireX. All these makes the APU's very much actractive, even more than the FX, just falls short of core-count redface.gif, if the APU had 6 or more cores then I'm sure that everyone would have gone for the APU instead of the FX.
Assuming Kaveri as fist gen of HSA APU's, how well do they stand against FX when the workload is openCL/HSA based?? Do these APU's perform better in such tasks as compared to even the FX-8xxx??

I think you're jumping the gun by about a week. Not yet. I'm somewhat skeptical given the leaks and recent slides.

lachen.gif Wow. That sounds so stupid when you put it that way, but that's exactly what they're doing. It would be more analogous to Intel if they created theses diles and them started calling them miles later on.

Measuring a nanometer sized object is done with a technique called nanoprobing. The "proper" way to measure nm size in process technology is to measure the silicone channel length between the source and the drain. This is called the gate length. The rest of the sizes are said to average that size but in reality some are a little bit larger and some are a little bit smaller. Currently however, if other people measure the gate length of Intel processors it is measured that the size is 1.182x larger than what Intel claims them to be. So Intel's 22nm node would be what the rest of the world calls 26nm. The 14nm node is close to 16.5nm in size. At the next node Intel may change their measuring again so the size can be something completely different. I believe the measuring by different companies actually has more to do with what the fab calls the process tech, not just what AMD wants to call it. AMD uses TSMC and GF for fab's to make the processors. Intel has their own fabs in house so they can call the tech whatever they want. The proper way to measure though is still to measure the source terminals to the drain terminals in the transistor. This puts Intel's 14nm actually behind both TSMC's 16nm and GF's 14nm in process size, however both of those are not actually in full production just yet so it doesn't matter. By the time those chips hit the streets Intel may be down at "7nm" which would bring them into the lead again for size.

I will always think of AMD's golden age as the socket 939 generation time. That was back when AMD obliterated Intel in performance across all market fronts. Hopefully AMD comes back to do with once again because it would be nice to see an even greater Golden Age than before. I believe AMD can do it one day, and this HSA stuff might be the way to it. AMD has a habit of inventing new technology that not only brings them the performance crown but also changes the PC landscape completely.
