Nvidia has announced the Tegra 4 which uses four ARM Cortex-A15 cores, along with a fifth battery saver core The design is similar to last years Tegra 3 which uses four ARM Cortex-A9 cores, along with a fifth 500 MHz battery saver core 

The performance of the Tegra 4 is supposedly more than double that of the  Tegra 3. But the real speed improved is in the new 72 core Graphics Processing Unit, which are said to be 6x more powerful than the 12 core GPU on Tegra 3.  The Tegra 4 also includes something Nvidia calls the Computational Photography Architecture, which is supposed to speed up camera related functions. All this is achieved while reducing battery consumption by 45%. I am not sure whether the Tegra 4 is based on 28 nanometer or 32 nanometer technology. The Tegra 3 was based on 40 nanometer tech.

All very impressive. One worrisome thing is no System-On-Chip (SoC) LTE. The Tegra 4 adds support for an optional 4G LTE modem, NVIDIAs own Icera i500 chipset. Unfortunately, this is likely to be more power hungry than SoC solutions like the Qualcomm S4.

Lenovo has released a new phone in the Philippine market, the Lenovo P700. The P700 is the most expensive phone Lenovo had released in the Philippine market, but it is also the most impressive. 

It really comes down to those three. The screen, the operating system and the price. This is not the fist entry level Android we have seen with a 4-inch display. We do have the Cherry Mobile W900 at Php9,999 but that phone comes with Android 2.3 out of the box, and we still have no word whether it will get an update to Android 4.0 (Ice Cream Sandwich).

Next is Ice Cream Sandwich. If you got a Android 2.2 phone two years ago, it would have served you pretty well till now with software compatibility. Android 4.0 should do the same thing. Within the limits of the hardware, it will give you software compatibility with most apps for the next two years or so. In our latest smartphone buyers guide, we stopped recommending any Android phone that does not come, or upgradeable to Android 4.0.

Of course, there is the price. There are several phones in the market at a similar price point upgradeable to Android 4.0. The closest competitor that comes to mind is the Sony Xperia Neo V. But the Lenovo P700 has some features that make it a very good alternative. 

It is par for the course for the price. The Lenovo P700, is a dual SIM phone. For many, that alone will make it a good choice. But actually we can ignore its dual SIM nature, and it still is an excellent choice.

The phone is powered by a 1 GHz ARM Cortex-A9 processor, with PowerVR SGX531 graphics and 512 MB of RAM. That is as competitive with the other phones at this price point. The PowerVR SGX531 graphics chip is about equivalent to the graphics of an Apple iPhone 3GS or LG Optimus Black P970. Instead of the Qualcomm, Texas Instruments or Samsung chipsets we are used to, this one runs on a MediaTek chipset. This chipset while new in the market has been found on previous Lenovo and Alcatel phones and I know of no serious issues with the chipset. 

Internal storage is 4GB of which we expect about 2.5 GB user available (we need to confirm this). Internal storage is expandable via MicroSD by another 32 GB. This is par for the course with other phones at this price point. It also has a 5MP auto focus camera, a front camera and can do 720 p video recording. 

Basically, there is nothing in the specifications which disappoint. So you do not make any serious compromises in selecting this dual SIM phone instead of a single SIM unit.

The battery makes it a really interesting option. The phone comes with a 2500 mAh battery. That is the same size as you find on Samsung Galaxy Note. This is a lot larger than the 1200 mAh to 1500 mAh you find in phones at this price range. This promises good battery life and could be this phone killer feature. 

A bit of a caveat. Phone design still counts. Some phones like the LG Optimus 4X HD has the same chipset as the HTC One X, similar specifications and a battery 20% larger. Despite the larger battery the LG Optimus 4X  HD but falls about 20% behind the HTC One X in terms of battery life (Source: GSM Arena). 

We have to wait for some user feedback to see how good the endurance of this phone is. But from the specifications, it looks promising. If you get the Lenovo P700 you get a 1000 mAh Belkin external battery pack making the Php10,999 price really amazing.

We have to actually spend some time on this phone before we put it on our recommend list. Still, if you are buying a phone now at this price, you should give this one a long look.
