Asus Transformer Drops Quad-core In Favor of Dual-core

MrSeb writes with this news from Extreme Tech: "In a move that will shock and disgust bleeding-edge technophiles everywhere, Asus has announced at Mobile World Congress 2012 that its new Transformer Pads — the high-end Infinity Series — will use the recently-announced dual-core Qualcomm S4 SoC. The critically acclaimed Transformer Prime, the Infinity Series' predecessor which was released at the end of 2011, used the quad-core Nvidia Tegra 3. Why the sudden about-face? Well, the fact that quad-core processors don't really have a use case in mobile devices is one reason — but it doesn't hurt that the Krait cores in the S4 are significantly faster than the four Cortex-A9 cores in the Tegra 3, too. The S4 is also the first 28nm SoC, while Tegra 3 is still on 40nm, which means a smaller and cheaper package, and lower power consumption to boot. The S4 is also the first SoC with built-in LTE, which was probably a rather nice sweetener for Asus." The Snapdragon S4 "Krait" CPU is still a bit shrouded in mystery as far as hard specs (Qualcomm has never been one to release docs), but it appears to be similar to the Cortex-A15 in performance; how they stand up to Intel's new Medfield designs remains to be seen.

Re:Core count obsession

[Elrond, Duke of URL]

The whole "core" obsession on mobile devices seems to be nothing but marketing talk. At least, as far as I have been able to determine.

I have a Droid 3 which has a dual-core CPU and using System Tuner I found that the second core was always shown as "offline". Doing some research online I found that the second core is kept offline to preserve battery life. Supposedly, it only comes online if the load is particularly high.

But, no matter what I did on the phone, I could never get the second core to come online. Using one of the tweaks available in System Tuner, I can apparently force both cores to be online all the time. However, the second core is still shown as offline and I still can't seem to get it to come online via high usage. Also, battery life doesn't seem to have changed.

So, this wonderful second core seems to be entirely useless and nothing but an item for the marketing checklist on the advertisements.

Bah...
