Intel's Medfield & Atom Z2460 Arrive for Smartphones: It's Finally Here
by Anand Lal Shimpi on January 10, 2012 8:00 PM ESTFinal Words
Intel finally did it. After almost five years of talking about getting into mobile phone form factors, Intel went out and built a reference platform that proved what they've been saying was possible all along. Furthermore, Intel also finally landed a couple of partners who are willing to show their support by incorporating Medfield into their product portfolio. The releases are still a few months away at the earliest (possibly even longer for Motorola) but it's much better news than Intel has ever reported before in this space.

The partnerships aren't out of pity either: Medfield is fast. I firmly believe had it been released a year ago it would have dominated the Android smartphone market from the very start. Even today it appears to deliver better CPU performance than anything on the market, despite only having a single core. GPU performance is still not as fast as what's in the A5 but it's competitive with much of the competition today, and I fully expect the dual-core version of Medfield to rectify this problem.
Based on the data Intel shared with us as well, the x86 power problem appears to be a myth - at least when it comes to Medfield. I'm still not fully convinced until we're able to test a Medfield based phone ourselves, but power efficiency at the chip level doesn't seem to be a problem.
Medfield and the Atom Z2460 are a solid starting point. Intel finally has a chip that they can deliver to the market and partners to carry it in. Intel also built a very impressive reference platform that could lead to some very interesting disruptions in the market.
While I'd like to say that Intel's Medfield team can now breathe a sigh of relief, their work is far from over - especially with more competitive ARM based SoCs showing up later this year. I'm really interested to see where this goes in the next 12 months...

french toast - Thursday, January 12, 2012 - link
Im sorry, although this isnt an area that i have a huge amount of knowlege on, i can say with some certainty that both Qualcomm and ST-E will have on die baseband shipping this year on 28nm, In qualcomms case the s4 processor that is being demoed with the Asus idea pad has one in.I can also say it has 2 main advantages that i know of (and likely many more that i dont)
1) When put on die and using the same process as in qualcomm and ST-E case it vastly improves power effiecency, a big problem with currant 4g.
2) As most of the components are included on die that you have mentioned, that means more space out side of the die, less hastle for the manufacturers and more space inside the device/phone for things like battery/or smaller device.
Regards to Apple, apple bought PA semi, back in 2007/08 and use it to design its A-series chips, whilst it hasn't used a complete custom licence, they have done some soft optimisations, im not privvy to what they are.
Samsung also acquired intrinsity around the same time, and used their custom logic to some minor power improvements to the cortex core..first seen on the hummingbird..as Apple uses samsung to manufacture there chips, you can bet some of that is licenced too.
Qualcomm ,nvidia (not tegra)and Marvel also have full custom license.

"We did manage to run SunSpider on the K800 though, which yielded a score of 1,971 -- just a hair faster than the 1,985 that we saw on the Galaxy Nexus."So either your test is off by about 600 points, or Engadget is blind.

I haven't played with the K800 that was being shown off but I am not familiar with the state of Lenovo's Android skin at this point, nor the details of how SunSpider was run. Our SunSpider numbers were run on the Medfield reference design which is what the K800 should be based on though.I'll try and do some digging.
Take care,
Anand

Who is going to hurt more?Intel entering into the Mobile Space or Arm entering the PC Space?

Well, Intel has plenty of padding to live on should things go sour. Plus they have compatibility on their side. I'd guess Intel will be fine no matter where things go, ARM now has the pressure on to be competitive.name99 - Wednesday, January 11, 2012 - link
"but one stand out issue was the A9 has a great execution core but seems to be more limited on the memory interface. Atom can support far more outstanding misses in L2 than the Cortex A9, which chokes bandwidth to the processor for anything not already in the L2 cache."It will be interesting to see if ARM take this seriously. Memory performance was THE downfall of PPC. It seems that companies and engineers think connecting to memory is not sexy compared to the core CPU; and I'd love to think that ARM are beyond this sort of childishness, but I honestly don't know.

ARM's A15 platform was also designed with servers in mind, and servers address and use the RAM alot more then basic applications so i think they'll, hopefully, have that fixed by A15IceDread - Wednesday, January 11, 2012 - link
I've always said that Intel would gain on ARM and eventually pass ARM. While I believed it would take a year more or two before they were this close on ARM, I'm still right :pThis will be interesting to follow, hopefully Amd gets their thump out and also does something on this market and then we have both Intel and Amd competing with cpu and gpu power for mobile devices.

I believe Anand Chandrasekher who was the brain behind Medfield left Intel due to failure of Intel-Nokia partnership. Any insight on that ?Android does seem a good choice for Intel compared to MeeGo as the ecosystem is already present.
stadisticado - Wednesday, January 11, 2012 - link
I'd more characterize him as the brain behind the Nokia tieup, not the silicon. Silicon would have been controlled by the design teams, not the product division GM, which Anand was.
