re: Microsoft's Big Risk As Ballmer Departs: Windows Phone
Misleading specification anyway. How many cores? More like, what are they being used for, and how well does their code use what's there?
If they were to count cores the same way in both phones, the Nokia Lumia 822 phone uses a Snapdragon S4 proc which has 2 Krait ARM v7 cores, plus a DSP core, plus the Adreno 225 or higher GPU (which has another 4 cores for graphics). So that's really 7 cores.
By comparison, the Samsung Galaxy S4 phone uses an Exynos Octacore (big.LITTLE Coretex A15 - that's really 4 cores at normal power and another 4 at low-power mode), and a PowerVR 544MP3 GPU (that's three cores). Plus the radio DSP (that's another core). However, that's only the UMTS version. So, really, that's really only 8 cores at a time - depending on which mode the device is in. Trust me - those low-power A7 cores are truly wimpy. Not even sure if they're useful with Android OS - jury's still out on that one. If anyone out there has that data, please chime in.
Difference of one core, in real life, at normal-power-on mode. Oh, and btw - still not really an apples-to-apples (no iOS puns here!) comparison, because the Nokia phone is an LTE phone but the version of the S4 I've actually used is a UMTS phone so not really the same beast. The LTE version of the Galaxy will most likely have a Snapdragon proc, because Qualcomm is really the only game in town when it comes to LTE.
So, what's all this mean? Bottom line is in the functionality. Both phones are very quick, performance-wise. The Samsung is slightly quicker, but that's probably due to the extra core. However, the LTE phone (on Verizon) is much faster with web/network-centric operations. The Galaxy certainly has a sharper display (full-on 1080p HD, compared to the 480x800 Lumia). However, if you've used one (and I have, my wife's got one on T-Mobile), you see rather quickly that it's not really that much quicker - and with the number of gestures/operation generally higher in Android than in WinPhone, it seems to equal out (in my tests, anyway).
End result - it's amazing to me how the Android-based Galaxy is not really much faster than my Nokia (which was $100US cheaper). There's a lot of bells-and-whistles on the Galaxy (eye-tracking, all kinds of sensor majik), but most don't matter to me, as I'm primarily a business user. Oh, and btw - those A15 cores on the Galaxy burn battery. My wife can barely eke out 24 hours. I usually get more like 1.5 days before my battery dies.
From a usability standpoint, I get real M$FT Office (I can edit powerpoints!), a the ever-awesome Nokia Here nav suite (offline maps that are really good!) and a highly-capable camera (awesome low-light shots).
So, I don't have a zillion apps to choose from. Big deal. Purely looking at the function/$ ratio, I am very glad I got what I got. I think a lot of others (many former BBN folks) might agree with me.
