Creeeping up on Samsung? No, catch AllWinner first

MediaTek needs to catch AllWinner and RockChip first before thinking about creeping up on Samsung. AllWinner and RockChip dominate the Chinese tablet market. Now they are also coming up reference designs with integrated 3G data and phone function.

AllWinner has already released two version of it's latest quad-core A7 based application processor: AllWinner A31 and A31s, and flooded the market.

Heterogeneous Multi-Processing vs Asynchronous
Wobbly   7/30/2013 1:12:44 PM
They are upselling HMP against Samsung's big.LITTLE, but they don't discuss Qualcomm's fully asynchronous Krait Quad-core, where every core can independently exercise DVFS.

How willl those implementations compare? Instruction per milliwatt?

My guess is that fully Asynchronous Quad Krait will have a distinct speed advantage under heavy load. MediaTek may (and it remains to be seen) have a small advantage at idle. The minimal configuration is two A7 at low V/F, vs. one Krait at low V/F. The interesting part will be in the middle ground. A 'moderate' load.

For the very lowest load, for example, audio player only mode, Qualcomm may win, because the Krait can be halted completely, and the low power audio subsystem operates on one of their Hexagon DSPs.

Also note from earlier in the thread, you can buy the updated Nexus 7 for $239 with a Snapdragon Pro and a full 1080 HD display. You do not have to 'white box' any more. I have the last generation, which was a very nice tablet. On of my co-workers as the 2013 model. It is very very nice.

@Dylan: And to your second question, writer to writer, ...

Oooh, is this like a secret society? Do we have special handshakes? (If so, why didn't anyone tell me about this before? :-)

@Tom: Are initialisms inevitable?

Based on past experiance I woudl say "Yes". My first job out of college was as a member of a team designing CPUs for mainframe computers at International Computers Limited (ICL) in the UK. The first coupel of days were really hard because everyone was talking in abbreviations.

The thing is that so long as you have the correct domain knowledge, abbreviations make conversations much more concise. Can you imagine saying something like "SoCs are ASICs or ASSPs augmented with CPU cores" in "long-speak"? Your audience would be asleep before you had finished. On the other hand, for someone who was not "in the trade," this sentence would sound like gibberish.

China's tablets
sranje   7/30/2013 10:43:10 AM
As usual, the US-centric Forward Concepts completely missed China's "white-box" tablets and their processors -- Allwiner, Actions, Rockchip, etc.

China tablets will soon account for nearly 50% of global tablets

Junko, how much more efficient the new architecture will be, if i can save >10% battery life then only consumer will notice the difference. Also, more cores does not mean that the device is faster, other factors such as RAM, software, graphics card etc make difference for a complete device. Hopefully consumers get their facts straight before shelling out money.

No, I bought it at Costco. And I'm pretty sure it was $199, but now that I think about it I can't swear to that. But it was in that vicinity. And I think it was on sale or something too. 

And to your second question, writer to writer, no I don't use it enough to consider it a must have. I do like it, and my kids love it. But until the other day, when both my oldest son and I suddenly felt like using it kind of at the same time, it had gone untouched for months. As you say, it's a cool thing to have handy when you are bored (which for me is seldom) and want to google something or check something out. For the kids, it's a fun platform for games, although honestly I am not sure why since they also have both Wii and Xbox.

Thanks Dylan. $200 sounds like a steal -- what was that? A doorbuster on Christmas Eve at Walmart or something?    Hey, writer to writer, I know you're not about to give up a PC. Do you use the tablet enough that you'd tell me to go get one? Or is it just a "nice to have" that you use once in a while as you get bored watching TV?

Just out of curiosity, do you use your phone for social media and news? I can't help but think that if I didn't have the iphone, I'd LIVE on a tablet.

Good catch, MicroMan!  Frankly, my eyes glaze over at every acronym we come across.  Humans aren't meant to communicate with alphabet soup. It leads to confusion in a context where clarity is appreciated.

Are initialisms inevitable? Or can we incorporate human language into our daily work to avoid confusing points like this one?
