Several companies have announced processors with big.LITTLE processing technology, but until recently only some Samsung Exynos 5 processors (Exynos 5420, 5422, and 5260) are found in products available for purchase. Available a few weeks ago, Teclast P98 3G tablet changes that as it is powered by Mediatek MT8135 quad core processor featuring big.LITTLE processing.
Teclast P98 3G specifications:
- SoC – Mediatek MT8135 (aka MTK8135) with two ARM Cortex A15 cores @ 1.5 GHz (1MB L2 cache), two ARM Cortex A7 cores @ 1.2 GHz (256KB L2 cache) in big.LITTLE configuration, and Imagination PowerVR GC6200 GPU
- System Memory – 2GB DDR3
- Storage – 32GB eMMC (UP to 120 MB/s) + micro SD slot
- Display – 9.7″ 2048×1536 IPS screen
- Video Output – HDMI
- Audio – Earphone jack, and AAC stereo speakers
- Connectivity – WiFi 802.11b/g/n, Bluetooth 4.0, GPS, FM
- Cellular – Built-in 3G WCDMA modem and one SIM card slot (Not for Wi-Fi only version)
- USB – 1x micro USB
- Camera – 2.0 MP front camera, 12.6MP rear camera
- Sensors – G-sensor, compass, 3-axis gyro
- Misc – Home, Vol +/-, and Power buttons,
- Battery – 8,500 mAh, or 7,500 mAh for Wi-Fi only version.
- Battery Life – 8 hours video playback time (Wi-Fi off), 15 hours audio playback (Wi-Fi and screen off, headphone output)
- Dimensions – 239.5mm(L) x 180.5mm(W) x 8.2mm(H)
- Weight – 608.2g
The tablet runs Android 4.2.2, and comes with a 5V/1.5V charger, a micro USB cable, and a user’s manual. Although the specs mention a Wi-Fi only version I could not find it anywhere for sale.
According to one seller, the Antutu score is 20500, which seems decent considering the screen resolution. Please noe that Antutu detects the CPU frequency as 1.2 GHz. I’m not quite sure how Antutu handles heterogeneous system with different CPU cores, so this may be a bug, or really means the Cortex A15 cores are clocked @ 1.2 GHz instead fo the 1.5 GHz advertised.
It would be interesting to find out more about battery life, but as usual it’s more complicated as there aren’t any standard tests. However, in some use cases it should be similar to a dual core Cortex A7 system, as the Cortex A15 cores should only be used for CPU intensive tasks, for instance while loading apps, or web pages. Audio and video playback should fully rely on the Cortex A7 cores.
