Tegra K1 Processor Ready for the 4K

Released during the latest Consumer Electronic Show in Las Vegas, Nvidia’s new mobile graphic chipset Tegra K1 is truly astounding. According to our on-site specialists, we’re witnessing the beginning of a new era in the history of graphic performances on mobile devices thanks to this revolutionary chipset which is pillorying Qualcomm’s Snapdron and Apple’s A7.

Tegra K1 a 192-core GPU


This astonishing result comes from the match between two technological monsters, a 192-core CUDA Kepler GPU – no, my Chin’Addicts, you’re not dreaming – and a 2.3GHz, 28nm-engraving NVIDIA 4-Plus-1™ Cortex A15 r3 Quad-core processor fitted with a third-generation core for battery saving which will provide a high-performance yet low-energy system. This NVIDIA SMP (Symmetric Multi-Processing) architecture gives the four cores the possibility to perform at high levels if need be, as each core works independently and is automatically activated and deactivated according to the workload.

Lenovo Thinkvision 28”

You won’t find it hard to understand that this display of power has a specific aim, which is to match the new 4k-ultra-high-definition, 4096×2160-pixel technical standard. This technology is not really relevant to a smartphone unless you have a good MHL connector. On the other hand, we find it very attractive when it comes to mobile equipment such as Android games consoles or PC laptops, tablets but also SmartTVs like Lenovo’s Thinkvision 28”, a real 4K monster delivered with an Android system and already fitted with the Tegra K1 processor, at a price which should not exceed 600€ in China.


The Benchmark to End All Benchmarks

Some specialized blogs like Tom’s Hardware have already examined it closely, via famous benchmarks like Futuremark 3D. The result is really impressive as the Tegra K1 pins down its contenders with its 25% additional performance as compared with the A7 on the 5S iPhone which, up to now, had been in the lead ahead of Qualcomm’s S800. Moreover, the test was run on an energy-hungry 4k screen and not on the iPhone’s small screen. You can imagine what the results would be like on a similar screen. It leaves us dreamy.

[HOWTO] How to keep an Android system at a high-performance level

From a certain point of view, caches are at the same time the strength and the weakness of an Android ROM. Two partitions, the cache and the Dalvik-cache – also called DalvikVM for ‘virtual machine’ – a little bit outside the system itself, allow you to store data on your applications and configurations so that you can put them faster into operation. You might compare them to virtual RAM. The problem with caches is their tendency to suffer from exponential growth, which, in the long run, can result in the exact opposite of what you initially looked for, and that is en excessive slowness. Last but not least, caches are apt to contain poorly written or erroneous data, which may result in a software bug or even a crash. Hence the absolute necessity to empty them on a regular basis. Strangely enough, that does not always appear in Android’s basic system options. Consequently you’ll have to resort to hidden functions you will find in the administration menu – the Recovery. The only trouble is that the original Recovery doesn’t feature these implemented functions, so you’ll have to use a modified Recovery. Inside this menu, you’ll go directly to Wipe or Wipe Cache Partition in order to launch this deep cleaning.







For those who feel a bit out of their depth about this kind of operation, there is an easier possibility, which is a Play Store application such as Cache Cleaner+ or App Cache Cleaner. The trouble is that the cleaning will only be effective on the Cache partition and not on Dalvik-Cache. The latter can only be cleaned by the Recovery.



Remember that the destruction of these two partitions is harmless to your device ; they automatically self-create again every time you switch it on, nor will you lose any data.




How to maintain a minimalist system



Most users like you and me have a tendency to install a whole lot of applications or widgets, more than is actually necessary. Keep in mind that the less your system stores in terms of applications, the faster it will be. Try to avoid installing too many useless widgets on the grounds that they’re cool. A widget is an ever-working system, consumes memory and so consumes energy. The less unnecessary widgets and applications you will have, the less energy-hungry your battery will be.



Safeguarding your battery






As we’ve seen, not having too many active applications may be a solution but it is not quite satisfactory in terms of energy saving.



Tip #1 – Manage as best as you can your screen light which is by far the most energy-hungry organ on a smartphone or a tablet. Automatic light control appears to be a good enough solution.



Tip #2 – Try to avoid having permanently switched-on data, whether it be with your 3G or your wifi. It is better to activate these functions only when you have need of them. Let’s not forget a connected device is constantly sending data in a perfectly invisible way. If you object to this tip, remember to deactivate all unnecessary synchronizations. Not only do they have you consume a lot of power, but they also have a voracious appetite for memory and data.



Tip #3 – Use a pedagogical application, as regards energy saving, such as for instance Battery Doctor which will teach you everything you need to know about your device’s energetic management. There are many other apps, like Juice Defender.




Putting these tips into practice should enable you, without constraint, to keep an efficient, simple, fast and low-energy operating system for your Android. As a result, your battery ought to get its second wind and multiply its lifetime by two or even three. And if you know tips we don’t, please let us know !

Inwatch X, the Great Chinese Smartwatch Contender

Maybe you missed last 13th January’s Inwatch conference.

A two-hour presentation we did not go to but of which we were able to read the abstract written in Chinese. ^^

The Inwatch is designed by the Ying Fun company, the founder of which, Wang Xiaobin, showcased his new products as well as his vision of future intelligent watches.

The Inwatch 1C is a simplified version of the first-generation Inwatch 1 smartwatch for the price of 1399 Chinese yuans (175€). (item here)

The next official version of the Inwatch Z has been presented as an Inwatch One deluxe edition featuring a transflective and waterproof IP7 TFT display for the price of 1788 Chinese yuans (224€).

We had already tested a prototype of the first Inwatch (link) which sold quite well in 2013 as it reached a turnover of one million yuans. This should give wings to its manufacturer and help him get ready for the next generations.


Inwatch X – Be Future

Designed together with a US team, featuring a South Korean curved screen produced by NeoView KOLON, the Inwatch X will fit your wrist perfectly.

We are still awaiting information on this Inwatch X but we already know its conception is already well advanced.

If you’ve kept informed of the big events at the CES, it’s probable you’ve already guessed that many makes such as Samsung, LG or Sony have launched the curved screen concept and that the Inwatch will accordingly follow this hi-tech tendency.

If the first-generation Inwatch didn’t really leave us breathless, it’s because it was there mainly as an experimental product. Its main purpose was to be tried and to face the teething troubles before the coming of a new generation of this Inwatch backed up by partners and investors who firmly believe in this made in Shenzhen watch designed to rival the Korean or Japanese giants currently planning to put their own smartwatches on the market.

In short, wait for new and exciting developments on JT Geek. 😉


Sffcccks, Zare and H&N in Wuxi

Welcome to Wuxi’s ‘Fake Street’ ! You are now discovering the latest and greatest Starbucks joke in China – second best only to Star Fucks, of course. Sffcccks Coffee is but one of the many fake installations seeing the light of day on Wuxi’s fantastic Fake Street, in the Jiangsu province.


Come drink your coffee or grapefruit juice in this magical place after buying of course the latest Appla and before accompanying your sweetheart on her try-on trip to Zare’s latest dress or H&N’s pantsuits. Hmmm, that felt good… And yet…


Ah, but – looks as if all these stores are empty ! Indeed, after a difficult on-site investigation, which local sources confirm, they are nothing more than logos used as posters and billboards to create the atmosphere of what sightseers consider their favorite pastime – fake shopping !

New Wireless Charging Technology for Mediatek

Taiwanese chipset manufacturer Mediatek is in the limelight again yet this time it’s not about a processor but a new wireless multimode charging solution. Here are more details.


On Android devices, wireless charging is no new concept but the trouble with present-day inductive charging is that it can charge a device only if it is set in a certain position, and it can only charge one device at a time. Mediatek’s new resonant charging system resolves the matter and offers a more flexible solution by enabling several devices to charge from one dock without being connected to it. In other words, it’s a dream come true for people who won’t rack their brains when they want to charge their devices. All they’ll have to do is put it close to the dock.


This technology, which was probably borrowed from genius Nikola Tesla, should be the talk of the town in the few months to come and you can count on JT Geek to follow it very closely.
