LG Optimus G Pro Superphone Announced in Japan

OMG. I think I had a Nerd-gasm. If it's USB 3.0 compliant, has a 24 bit 96khz DAC (with software support for all the open source audio codecs), supports SDXC, and is 64 bit... It would be perfect... and from the future!



Honestly, what is the status of multithreading in smartphone software? With all of these quad cores coming out lately, you have to ask yourself, does all of that power really get used, or are we just buying millions of dead transistors?

Also, 1.7 gigaherts in a phone sounds impressive, but is it really? How does this compare to, say, an ivy bridge that was also running at 1.7Ghz?



I use a CPU monitor on my Tegra 3 tablet, and you can see the cores light up when you browse desktop versions of websites and in a number of games though quite frequently I see them use 2 cores which may be efficiency on the part of the game or the CPU trying to save power by reducing core usage.

Even reading MPC on my tablet, you can see all the cores fire up when you change pages in an effort to make things as snappy as possible. So I would say, yes they do get used.

On the subject of ARM vs x86, I would imagine watt-for-watt that ARM wins handily but for sheer power, you aren't going to beat a full voltage processor with a phone.



1) Android 4.1 has support for, and uses, code that does well in parallel.
2) Trust me when I say that no company wants to give you millions of useless transistors. They have to pay for that! I can't tell you how big Speed/Transistor Count/Energy consumption is when you're designing a chip. (It can get annoying... but I love it.)
3) Apples and Oranges. CISC != RISC. There really isn't any way to compare them. I know there will be people who scream "Use the Drystone test!", but I don't find that to be particularly fair.
