The Galaxy Note 4, Samsung’s current flagship phablet, is already available in two variations: one with a Samsung Exynos 7 processor (SM-N910C), and one with a Snapdragon 805 (SM-N910S). The difference between them is almost negligible, but a rumor this morning out of the fairly-reliable-for-Samsung-rumors SamMobile suggests that Samsung is testing another variation of the Note 4, this time with Snapdragon’s upcoming 810 system-on-a-chip.

Googler Ami Fischman, a self-dubbed “Watt Wrangler”, just announced a new battery-saving Chrome Stable release.
“We recently enabled GPU-accelerated video decoding for Chrome on Windows,” wrote Fischman on the official Google Chrome blog. “Dedicated graphics chips draw far less power than a computer’s CPU, so using GPU-accelerated video decoding while watching videos can increase battery life significantly.”
Fischman noted test results show batteries last 25 percent longer with GPU-accelerated video decoding switched on. So now, Chrome users on Windows can watch more YouTube videos, as Fischman noted, without worrying about dwindling battery life.
Chrome users can even access website permissions, such as geolocation, much more easily with the new release:
This saves you from having to dig through settings pages to find these permissions. Now, simply click on the page/lock icon next to a website’s address in the omnibox to see a list of permissions and tweak them as you wish.
This latest release also includes an option to send a “do not track” request to websites and web services. The effectiveness of such requests is dependent on how websites and services respond, so Google is working with others on a common way to respond to these requests in the future.

Anandtech has published some interesting findings based on their extensive Samsung Galaxy S II review. It’s the first smartphone to use the graphics processing unit based on the Mali-400 core from ARM Holdings, a fables chip maker from the UK. In fact, Samsung has engineered and manufactured its own system-on-a-chip solution for the handset.
They call it the Exynos 4210 and it combines a dual-core Cortex-A9 CPU core and the aforementioned Mali-400 GPU sporting four cores. The resulting performance, says Anandtech, is comparable to Texas Instruments OMAP 4 chip that incorporates Imagination Technologies’ PowerVR SGX540 GPU core. However, the quad-core 1.2GHz Exynos 4210 probably won’t hold a candle to iPhone 5, which will likely carry the same dual-core processor-GPU combo as the iPad 2’s 1GHz A5 chip:
Samsung implemented a 4-core version of the Mali-400 in the 4210 and its resulting performance is staggering as you can see above. Although it’s still not as fast as the PowerVR SGX 543MP2 found in the iPad 2, it’s anywhere from 1.7 – 4x faster than anything that’s shipping in a smartphone today.
Interestingly, and per the GL Benchmark seen in the above image, the Exynos 4210 is more than twice as fast compared to the Galaxy Tab 10.1 that runs Nvidia’s Tegra 2 chi. It’s also nearly four times speedier than iPhone 4’s 800 MHz A4 chip which has the PowerVT SGX535 GPU core. However, the 4210 falls short in the triangle throughput department.
The publication this this could be a big disadvantage over the iPad 2’s A5 processor that clocks nine times the graphics performance of the original iPad’s A4 chip. Triangle throughput is important in graphics-intensive games and will become key in “future games that may scale along that vector rather than simply increasing pixel shader complexity”. The video of Anandtech’s Samsung Galaxy S II review is right after the break.
