Asus Transformer Drops Quad-core In Favor of Dual-core 207
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.

Another major advantage of multi-core systems is if a poorly written piece of software locks up it is highly likely to also be single-threaded and your system will chug along nicely despite the misbehaving program, allowing you to kill the process (by comparison, on a single-core system you're likely to suffer through five minutes of waiting for the system to respond before you are able to kill the process).

"Bleeding edge technophiles" are a bit sensitive! (Score:2)
If all it takes to "shock and disgust" "bleeding edge technophiles" is a technical decision to pick a CPU with faster cores instead of more of them, then these "bleeding edge technophiles" must not get out of Mom's basement very often and are in need of some serious therapy.

They run it to be able to run the radio on the same hardware. But that means that it won't necessarily run anything in bounded time, hence the need for more than one core. Oh, it also comes in 2 and 4 core packages.

Only the LTE model (Score:3, Informative)
The reason is LTE (Score:3, Interesting)
The Tegra3 isn't compatible with any LTE modems and won't be for several months so ASUS opted to use the S4 for all 3g/4g transformers so they could have something for carriers to sell nowish. The Wifi only models will keep using the Tegra3. Either way this isn't really something ASUS can fix itself since Nvidia never bothered getting its product to support any LTE modems.
Re: (Score:2)
The story is just that Asus preferred the Tegra3 when having to chose a platform without LTE. And when taking into account LTE, it preferred the new Qualcomm S4 combined AP and LTE solution.
Now when you say:
The Tegra3 isn't compatible with any LTE modems and won't be for several months
It can be misunderstood as an issue on the Tegra3 side, which would be unfair. There's nothing special to do to hook a LTE baseband to a T3. It's all Android and very common interfaces. The issue is more

That and the S4's got a higher performance profile with a lower power consumption for actual ICS usage. It's as much about battery life and perceived performance as it is LTE support out of box.

First HTC drops its quad core chip for a dual core (Score:5, Interesting)
First HTC suddenly drops its quad core chip for a dual in a phone that
was supposed to have a quad core chip since it was leaked back in July.
And days later, Asus drops a quad in favor of a dual core.
Same chip was dropped.
Someone... is keeping a secret. There is a problem with the quad core
chip and 'something' new(er) that is appearing in the phones. I read that
an LTE chip appeared in the "One X", while the quad core disappeared.
Is LTE and quad core not playing nice? Are there production shortages?
Overheating issues, battery issues?
The whole story isn't out. I'm curious what it is. I've been waiting
and salivating at the promised "Quad" core offerings for smartphones.
The Samsung SIII is supposedly going to have one, but from a different
company, their own Exynos chip. So, we won't see that quad be cut in half.
Hopefully.
Regardless of what the non-power users say about not needing more cores,
I see my dual cores maxed out regularly. I need the extras, I was willing to
sell my life, I mean soul, I mean sign a new 2 year contract for it.

The problem is Tegra does not support LTE - this is a problem for sales in the USA.
Europe will continue to get the full spec, full speed, Nvidia Tegra3 devices
Re: (Score:2)
It has nothing to do with the quad core aspect of the Tegra3 and everything to do with Nvidia being stupid and not bothering to get it supported/certified by any of the LTE chipset manufacturers.

I bought a Prime as soon as they were available where I live. The first time I switched it on, it updated to ICS--great. I headed over to XDA-developers to see how to root it, and found stickies dedicated to the various problems that the devices have--random reboots, lockups, terrible WiFi performance, and so on. It seems that these problems are related to the serial numbers, too. ASUS even has an "official" support thread on XDA in which (what I presume is) an engineer fields questions about said random pr

Ummm Tegra 2 was the fastest platform for Android for quite some time. The G Tablets are still pretty blazingly fast. The issue is just that Tegra 2 was released for such a short time before Tegra 3 came out that it never got much saturation, and then Tegra 3 came out with a bunch of faster options close on its heels.
NVidia has great hardware engineers, but awful software driver people on their mobile platform. They have done a terrible job supporting their chipsets after release with Android, or getting good manufacturers to adopt them.

so is it fast or is it not? the terrible sw excuse was employed by intel for many years as to why their gpu's sucked since they weren't as fast as their promises..
