Lava Xolo X900 Review - The First Intel Medfield Phoneby Brian Klug on April 25, 2012 6:00 AM EST
For Intel, the road to their first real competitive smartphone SoC has been a long one. Shortly after joining AnandTech and beginning this journey writing about both smartphones and the SoC space, I remember hopping on a call with Anand and some Intel folks to talk about Moorestown. While we never did see Moorestown in a smartphone, we did see it in a few tablets, and even looked at performance in an OpenPeak Tablet at IDF 2011. Back then performance was more than competitive against the single core Cortex A8s in a number of other devices, but power profile, lack of ISP, video encode, decode, or PoP LPDDR2 support, and the number of discrete packages required to implement Moorestown, made it impossible to build a smartphone around. While Moorestown was never the success that Intel was hoping for, it paved the way for something that finally brings x86 both down to a place on the power-performance curve that until now has been dominated by ARM-powered SoCs, and includes all the things hanging off the edges that you need (ISP, encode, decode, integrated memory controller, etc), and it’s called Medfield. With Medfield, Intel finally has a real, bona fide SoC that is already in a number of devices shipping before the end of 2012.
In both an attempt to prove that its Medfield platform is competitive enough to ship in actual smartphones, and speed up the process of getting the platform to market, Intel created its own smartphone Form Factor Reference Design (FFRD). While the act of making a reference device is wholly unsurprising since it’s analogous to Qualcomm’s MSM MDPs or even TI’s OMAP Blaze MDP, what is surprising is its polish and aim. We’ve seen and talked about the FFRD a number of times before, including our first glimpse at IDF 2011 and numerous times since then. Led by Mike Bell (of Apple and Palm, formerly), a team at Intel with the mandate of making a smartphone around Medfield created a highly polished device as both a demonstration platform for OEM customers and for sale directly to the customer through participating carriers. This FFRD has served as the basis for the first Medfield smartphones that will (and already are) shipping this year, including the Orange Santa Clara, Lenovo K800, and the device we’re looking at today, the Lava Xolo X900. Future Medfield-based devices will deviate from the FFRD design (like the upcoming Motorola device), but will still be based loosely on the whole Medfield platform. For now, in the form of the X900 we’re basically looking at the FFRD with almost no adulteration from carriers or other OEMs.
The purpose and scope of this review is ambitious and really covers two things - both an overview of Intel’s Medfield platform built around the Atom Z2460 Penwell SoC, and a review of the Xolo X900 smartphone FFRD derivative itself.
Beginning April 23rd, Intel, through Lava International, began selling the Xolo X900 smartphone in India for INR 22000 (~$420 USD). As we’ve stated before, the design and construction of the Xolo X900 almost identically mirrors the Intel FFRD we’ve seen before, from the specifications and Medfield platform itself, to industrial design and exterior buttons.
It’s a testament to the polish of the reference design that Mike Bell’s team put together that Intel is confident enough to basically sell exactly that device through carrier partners. I’ll admit I was skeptical upon hearing that Intel would basically be selling their MDP to customers, but the device’s fit and polish exceeded my expectations and are clearly those of something ready for customer abuse. First up are the X900 specifications in our regular table (below), Xolo also has its own nicely presented specifications page for the X900 online.
|Apple iPhone 4S||Samsung Galaxy S 2||Samsung Galaxy Nexus (GSM/UMTS)||Lava Xolo X900|

|Battery||Internal 5.3 Whr||Removable 6.11 Whr||Removable 6.48 Whr||Internal 5.4 Whr|
It’s interesting to me that Intel, Qualcomm, and others identified and went with WSVGA (1024x600) for their reference designs in roughly the same 4" size. It’s a display form factor that corresponds almost exactly to 300 PPI, and looks great, but more on that later. The rest of the X900 is basically what you’d expect for a smartphone of this generation, and on par with the Android competition that Intel was targeting, perhaps minus microSD expansion.
The design language of the X900 (and Intel FFRD) is a pretty obvious nod to the iPhone 4/4S design, complete with chrome ring, similar button placement, and a few other things. Likewise, the X900 uses a microSIM whose tray is located on the right side and makes use of an ejector port and tool. Below that is the X900’s two-stage camera button, and then speaker port. There’s a matching speaker port on the other side in the same area.
MicroUSB is located at the very bottom slightly off center, and microHDMI is on the left side. Up at the top is power/standby and the standard headphone jack. There’s no real surprises here, and despite being entirely plastic-clad, the X900 feels pretty decent in the hand.
The backside is a soft touch material which we’ve seen and felt on countless other smartphones before. The only downside to the X900 design is lack of a user replaceable battery - the backside is permanently attached. At the top is the 8 MP camera port, adjacent LED flash, and secondary microphone for noise suppression.
The front of the X900 is likewise pretty standard fare - up top are the 1.3 MP front facing camera, speaker grille, ambient light sensor, and proximity sensor. At the bottom are the four Android capacitive buttons whose design mirrors the FFRD we’ve seen before.
Again there’s nothing super crazy about the design or construction of the X900, it’s an extremely polished reference design turned consumer electronic that feels solid and ready for use as a daily driver if you’re up for it. Enough about the superficial stuff though, let’s talk about what everyone wants to know about - Medfield and Android on x86.

superPC - Thursday, April 26, 2012 - linkWell this atom only has 1/4 of conroe dual core transistor count right now. a move to 22nm could bring conroe level performance.
Khato - Thursday, April 26, 2012 - linkRemember, conroe class performance simply indicates a general IPC level. I don't expect something on par with an E8600, more like a SU9600. It's quite feasible on the 22nm LP process, and actually is roughly in-line with the one Atom performance roadmap from awhile ago.
extide - Wednesday, April 25, 2012 - linkThat wont be happening for a while, but from what I have heard 2013 will bring us a second gen (out-of-order) atom on a mature 22nm process. We should see 2Ghz+ clockspeeds and 2 cores, plus a healthy IPC boost. This is going to be an exciting battle to watch, the old Intel vs AMD gig is kind of stale, so its awesome to see a real challenge for Intel again!
A5 - Wednesday, April 25, 2012 - linkULV Haswell will have a TDP an order of magnitude too high for a phone form factor. Tablets, maybe.
MonkeyPaw - Wednesday, April 25, 2012 - link"We waited years for Intel's first smartphone, now the question is how long do we have to wait for the first irresistable one?"
It wont matter. Intel will dump millions into advertising, and every single phone maker will have ads for their new x86 phones, ending with the usual Intel chorus.
dougys - Wednesday, April 25, 2012 - linkI read somewhere else a few weeks back that the iPhone 5 could have Intel Inside. However, something else I read suggested that if they were to do this all the apps would have to be re-written... Does anyone have any thoughts/insight?
tipoo - Wednesday, April 25, 2012 - linkApple has a few architecture changes under its belt, but I very much doubt it, not for this chip. Apple bought chip design companies and spends more on internal chip design year after year for good reason.
Not sure about iOS compatibility but this chip can run any Android apps just fine as the article points out through binary translation, I think Android apps use Java and iOS uses C++ though so I'm not sure if that would still work.
If Apple was to go to an outside design for its chips (which I highly doubt it will) I'd hope it would be for Qualcomm, Krait is amazing.
dcollins - Wednesday, April 25, 2012 - linkApple will not move to an Intel chip anytime soon because they have been very successful in designing their own SoC. Just look at the battery life benchmarks: Apple crushes everyone in Hours/Watt*Hour. Plus, doing it in house gives them more flexibility on the overall design of their boards.
There is a small chance of Intel manufacturing chips for Apple, but that is a long shot as well. Chips manufactured on Intel's 22nm 3d gate process would be incompatible with chips produced on competing 28nm processes (different physical size) and Apple is traditionally opposed to single sourcing crucial components.
tipoo - Wednesday, April 25, 2012 - linkWhy does the GN get worse flash performance than the Nexus S and even Nexus One? That isn't a resolution dependant test, right?
I'm also curious why the dual core Atrix barely does better than the single core Nexus S in Vellamo, was that just a bad SoC design or is it because it runs an older OS?
tipoo - Wednesday, April 25, 2012 - linkI also just got 915 on my Nexus S rather than 622, but I'm using an unofficial Cyanogenmod 9 build from XDA forums.
