Samsung Gear 2 Smartwatches are Powered by Exynos 3250 SoC

April 10th, 2014 No comments

When Samsung announced their Gear 2 and Gear 2 Neo smartwatches running Tizen, they only vaguely mentioned a dual core processor running at 1 GHz powered the devices. SamMobile reports the two watches should be powered by a new processor called Exynos 3250 with two cores and clocked at 1 GHz as initially announced.

Ifixit also made a tear down of the Gear 2 watch, and at first, it seems Exynos 3250 is nowhere to be seen, but it turns out it’s probably combined with a DRAM (and Flash?) package named KMF5X0005M, and shown inside a red square in the picture above.

Samsung Galaxy Gear, the company’s first smartwatch, was a modified version of Exynos 4212 dual core processor, but using only one core and downclocked to 800 MHz. SamMobile thinks the Gear 2 can use a dual core processor @ 1 GHz, due to battery life gains achieved by replacing Android with Tizen operating system.

Beside the Exynos processor, ifixit teardown shows other components such as the 2MP “RINATO” camera, 300mAh battery, 1.63″ display (320×320), accelerator, gyroscope, and more. The watch is said to be easy to open, and the (non-standard) battery can be replaced without special tools.

Bluetooth Slide-out Keyboard Cases for Android Smartphones and iPhones

March 21st, 2014 No comments

Yesterday, one reader told me he wished manufacturers would release high-end smartphones with a slide-out keyboard, something similar to what Asus has done with Eee Pad Slider SL101 or Archos with their 101 XS Tablet. So I had a look in case some Chinese manufacturers had done a phablet with a slide-out keyboard and Mediatek MT6588 or MT6592 SoC, but all I could find are some old 2011 or 2012 smartphones with Android 2.3 and low specs by today standards. If you own a best selling phone however such as the Galaxy S4, Galaxy S5 or iPhones, there are some cases with a Bluetooth slide-out keyboard that can add this functionality to your phone.

Galaxy_S4_Slideout_Keyboard

Galaxy S4 with Slide-out Keyboard

The one pictured above is “QQ-Tech Ultra-Slim Slide-Out Detchable Multifunction Wireless Bluetooth Keyboard Case” for Samsung Galaxy S4  which you can find on Amazon for $23. The case comes with a micro USB cable to charge the keyboard, and a user’s manual. If you own another phone, you can just search for slide-out keyboard + your phone model in Amazon, Aliexpress or DealExtreme, and if you’re luck find a case that matches. There’s even a keyboard case for Galaxy S5 even though the phone has not shipped yet, and plenty of keyboard cases for iPhones.

You can watch the video below to see how such cases work. The model below is for Galaxy S4. The phone will get relatively thick, but you could always remove the case when you don’t need it. After initial setup (Bluetooth pairing),  you can use the keyboard normally. I’m not quite sure why the reviewer below used the phone screen in landscape mode…

Nvidia Tegra K1 32-bit and 64-bit Benchmarked with Antutu

March 6th, 2014 3 comments

Nvidia announced their latest Tegra applications processors at CES 2014 with the Tegra K1 32-bit and 64-bit ARM SoCs, as well as Tegra K1 MVC for automotive application. The 32-bit version comes with four Cortex A15 cores up to 2.3 GHz plus a companion core, and the 64-bit version with 2 ARMv8 cores (Cortex A53?) clocked up to 3 GHz. Both SoC features a 192-core Kepler GPU, and we’ve been shown some high-end graphics demo (OpenGL, OpenGL ES, OpenCL…) with in the reference tablet. Some charts has surface showing both 32- and 64-bit Tegra K1 scoring well over 40,000 and with an excellent 3D graphics score.

Tegra_K1_AntutuThe benchmark was run in reference platform with 32-bit or 64-bit Tegra K1, as well as the Tegra Note P1761 tablet with a 32-bit quad core Tegra K1 processor apparently clocked at a lower frequency, and with a not-that-good flash. The dual core, 64-bit version of the Tegra K1 scored 43,617 points (@ 3 GHz), whereas the quad core, 32-bit version achieved 43,851 points in Antutu 4.0. The tablet however just got 38,323, which is still a pretty good, and possibly more relevant to what we’ve see in retail devices. The 64-bit reference platform runs Android 4.4.2 with Nvidia Tegra K1 ARMv8 dual core processor clocked between 510 MHz and 3,000 MHz, a display with 1920×1080 resolution, 2GB RAM and 32 GB RAM (Source screenshot). Tegra_K1_vs_Snapgradon_805

The chart above shows Tegra K1 clearly outperforming Qualcomm Snapdragon 801, which is the best processor available (almost) right now, as it is part of the Samsung Galaxy S5.  Please note, I could not trace the origin of the different charts, and I just know it was posted on some Chinese website, and I do not know exactly which hardware was used to test each processors. This is important because benchmark results may be smaller in a smartphone or tablet, compared to a development board as you can’t just put a huge heatsink in a mobile device. But the results are interesting nonetheless to get a rough idea of the likely performance.

I usually prefer more detailed comparisons, and Sam Mobile posted the benchmark for both the Qualcomm 801 (SM-G900R4) and Exynos 5422 (SM-G900H) version of the Galaxy S5. We only have the benchmark details for Exynos 5422 version which is compared to the Galaxy Note 3 in the chart below.

Qualcomm 801 vs Exynos 5422

Qualcomm 801 vs Exynos 5422

The summarize all this in a table.

Total DB  I/O Storage I/O 3D Graph. 2D Graph. RAM Speed RAM Op. CPU Float CPU Integer Dalvik Multitask
Tegra K1 (2x ARMv8) 43617 645 2534 10997 1585 5078 3059 2291 4207 3875 9349
Tegra K1 (4x A15) 43851 645 2402 10939 1594 2229 2285 5461 4929 3775 9592
Exynos 5422 (4x A15, 4x A7) 35445 540 780 10401 1642 459 2680 4839 5339 1065 7700

According to these results. A dual core ARMv8 processor will perform just as well as a quad core Cortex A15, except with tests relying on more cores (CPU tests). RAM performance is way better with a 64-bit processor as expected. The biggest surprise is that the ARM Mali-T628 in Exynos 5422 appears to be just as good as the Kepler GPU found in Tegra K1.  The things that kill the Galaxy S5 is poor database I/O, RAM speed, and dalvik performance. For some reasons it does not score very well with multitasking despite having 8 cores. maybe the current big.LITTLE implementation and/or Antutu do not leverage the eight cores yet.

As mentioned above, the Tegra K1 scores have been done on a reference platform, and such scores may not be achieve on mobile devices due to heat dissipation issues. SemiAccurate has published several articles about Nvidia Tegra K1 saying the numbers released by the company were deceitful, and their latest article claims a 12V/5A (60 Watt) was used by Nvidia for their Tegra K1 demo at CES 2014, the only problem, if the picture is correct, is that it was for Tegra K1 MVC for automotive applications which certainly does not have the same power requirements as mobile devices. Even though, for now, the numbers looks promising, albeit not amazing, we’ll have to wait and see actual retail hardware to get a proper idea of the performance and power consumption of Tegra K1.

Samsung Chromebook 2 Features Exynos 5 Octa SoC, Comes with either 11.6″ or 13.3″ Display

March 4th, 2014 12 comments

Samsung has just launched the Chromebook 2 Series with two models based on on Exynos 5 Octa SoC, available in 11.6″ (1366×768) and 13.3″ (1920×1080) configurations, and featuring 4GB RAM, 16GB eMMC, and a longer battery life thanks partially to big.LITTLE processing technology. Samsung expects the new Chromebooks to be used for work, education, and entertainment.
Samsung_Chromebook_2

Thanks to strong hardware specifications, these new ARM based Chromebooks will certainly offer performance similar to, or even outperforming, existing many Intel Celeron based Chromebooks, and at the same time offer a longer battery life. It’s a nice upgrade to the Exynos 5250 powered Chromebook launched in 2012, especially the addition of a model with a 13.3″ display with FHD resolution. The 13.3″ model has an Exynos 5 Octa processor clocked at 2.1GHz which should be the latest Exynos 5422, whereas the 11.6″ model might use Exynos 5420 instead (TBC).

The company also mention the 13.3″ Chromebook 2 features high-power stereo speakers (2Wx2) and a noise reducing array microphone optimized for Google+ Hangouts messaging and video calling. Thanks to Chrome OS, the laptops will boot within seconds, be updated automatically, and all information and files are saved, and encrypted to your account. Some premium adds such as Air Droid Premium, Wunderlist Pro, and LittleBridge.com will be included with the device.

The 11″ and 13.3″ Chromebook 2 will be available (in the US) in April 2014 for respectively $319.99 and $399.99.

Samsung loaned a few Chromebooks 2 to blogs in the US for some reviews and hands-on, and the reviewers were left with mostly positive first impressions:

Samsung Unveils Exynos 5 Octa 5422 and Exynos 5 Hexa 5260 SoCs

February 26th, 2014 1 comment

As expected, Samsung announced the Exynos 5 Hexa 5260 hexa-core processor and, the not-quite-expected Exynos 5 Octa 5422 octa-core processor at Mobile World Congress, both of which feature ARM’s big.LITTLE processing technology, and ARM Mali-T628 GPU. Still no news about their 64-bit processor.

Exynos_5_octaExynos 5260 will feature two ARM Cortex A15 cores up to 1.7GHz, and four Cortex A7 cores up to 1.3GHz, with full support for HMP/GTS. Contrary to initial reports the new processor is not based on Mali-T624 (as shown in Antutu), but according to Samsung Exynos 5 Hexa page, it will instead use Mali-T628 just like in Exynos 5420 and 5422. This processor could end up with the best price/power consumption/peak performance combo, as few application are able to use more than 2 cores. The SoC also features an embedded Display Port (eDP) interface, and with a memory bandwidth up to 12.8GB/s, supports supports WQXGA (2560×1600) resolution. Exynos 5 Hexa’s video codec supports 1080p 60fps encoding and decoding of H.264, MPEG4, VP8, and more.

Exynos 5422 appears to be a update to Exynos 5420 octacore SoC, with four Cortex A15 core clocked at up to 2.1GHz, and four Cortex A7 cores clocked at up to 1.5GHz. The GPU is still Mali-T628, and the processor also supports HMP. One key difference with Exynos 5260 is that it supports 4K hardware video decoding, albeit outputted to a display up to WQXGA (2560 x 1600) resolution. It’s quite likely Exynos 5422 will be the processor running in the Exynos version of the Galaxy S5Exynos 5422 page on Samsung website has with very few details at this time.
