Fungsi paparan HDR adalah fungsi premium yang buat masa ini hanya ditemui pada peranti-peranti premium. Dengan HDR, paparan gambar pada skrin bukan sahaja lebih terang malahan kelihatan lebih hidup. Razer Phone yang dilancarkan tahun lalu akhirnya memasuki senarai peranti yang menyokong penstriman kandungan HDR Netflix.
The latest Google Chrome update now supports HDR for Windows users
Google has released a new update to Chrome that addresses some major gripes with the browser. Chrome 64 now includes the ability to mute entire sites that auto-play videos, so you won’t be constantly dogged by an annoying video.
This is particularly handy on sites that insist on having the video follow you with sound on as you scroll down a page, so the ability to right-click a tab and mute it forever is a godsend. While you could mute tabs before, it was only temporary, and the audio would start up the next time you visited the site.
In addition, Google added HDR support for Windows users, which will also require you to have the Fall Creators Update and an HDR-compatible monitor and graphics card.
Chrome 64 also offers protection against the Meltdown and Spectre vulnerabilities for Windows and Mac users by disabling the SharedArrayBuffer feature by default and modifying the behaviour of the performance.now API.
On top of that, the new Chrome guards against what Google calls an “abusive experience”, where ads unexpectedly redirect you to another site. These attempts will be blocked by Chrome, and you’ll instead get a notification that the page is trying to redirect you.
There are more robust ad-blocking features as well, and Chrome now lets you block and mute AdSense ads. This means you can temporarily block certain ads, in addition to related ones, from being shown on the pages you visit.
Google hari ini mengumumkan yang mana mereka akan menambah sokongan HDR (High Dynamic Range) ke pelayar web Chrome pada Windows.
Seperti ramai sedia maklum, dengan penambahan HDR ia akan menawarkan warna yang lebih jelas dan terang, serta penggunaan hitam yang lebih hitam. Walaubagaimanapun, untuk menikmatinya, anda masih memerlukan monitor dan kad grafik yang menyokongnya.
Selain daripada sokongan ini, Google turut mengumumkan yang mana mereka kelak akan melancarkan sokongan realiti-maya di web bagi memudahkan lagi anda menikmati kandungan interaktif melaluinya.
Billed as the flagship mobile processing platform of 2018, the new Snapdragon 845 will even populate a new class of always-on, always-connectedlaptops. For Qualcomm, that’s opening the company up to a whole new ballgame. And if they do manage to increase the total available market of the notebook ecosystem, that’s good news for the PC platform and for Qualcomm’s financial standing too.
The Snapdragon 845 has a completely new architecture that sees almost all its major subsystems renewed with more performance capabilities and designed to be ever more efficient. There’s a fair bit that Qualcomm has touched upon and all updates are revolving around delivering great experiences across five key pillars – Immersion (imaging + extended reality), AI, security, connectivity and of course, performance.
And by advancing all these integral components, what can you expect in a typical day of using a Snapdragon 845 device in the future? Qualcomm has it all visualized for you:-
That might be oversimplifying things, but the video is a good representation on having your lives enriched by the next flagship processor that not only does what you need, but preempting to serve your needs just the way you want it, when you need it. That’s the stuff of artificial intelligence (AI) and it’s why the Snapdragon 845 is three times more capable in AI related tasks than the current flagship Snapdragon 835. There’s much more to the Snapdragon 845, so let us run down on the advancements in each pillar/component of the processor and how that all adds up.
In a nutshell, Qualcomm is gunning for all day battery life and beyond coupled with super-fast charging, continuous 4K HDR capture for more than 4 hours (adhering to the UltraHD Premium certification), over 3 hours of continuous VR gameplay and over two days of non-stop Ultra HD voice calls.
To achieve all this in mind, there are various areas that Qualcomm has improved the Snapdragon 845 to bring about a high level performance increase of up to 25 percent over its predecessor, including a 30 percent faster graphics engine, 2.5x speedier display throughput, 3x increase in AI related processing tasks and all of this is coupled by a 30 percent better power efficiency too. How did it pull this off? Let’s take a closer look at the Snapdragon 845 SoC.
The Snapdragon 845 is a 10nm SoC fabricated by Samsung’s foundry and is built on a 2ndgeneration 10nm LPP (low power profile) process technology, which is a step up from the first generation 10nm LPE (low power entry) process used on the Snapdragon 835. While Qualcomm isn’t keen on disclosing transistor count figures for illogical comparison ‘wars’, they did share that the package is roughly the same size as the Snapdragon 835 at about 12.4 x 12.4mm. For all the processor’s new capabilities it’s safe to assume it packs ever more transistors to make that possible.
For one, know that the new Kyro 385 CPU is now endowed with a 2MB shared L3 cache and there’s even a further 3MB of system cache that all other inter-SoC components can ride on. This cache hierarchy didn’t exist before and while Qualcomm insists it reduces power by limiting memory access bandwidth 40 to 75 percent and helps net overall system performance uplift (which we agree on an theoretical level), it’s interesting to note that Qualcomm also once said the additional cache was omitted because the potential benefits did not trump the extra cost in higher energy consumption and die space for the Snapdragon 820. While that was a different era, different process technology and a different set of CPU cores, it’s still an interesting observation nonetheless. Perhaps the change in cache hierarchy has to do with the increased processing demands of each processing subsystem, such as the Hexagon 685 DSP which does much of the heavy lifting for AI processing tasks. A fast nearline cache can come in handy for its machine learning tasks.
Speaking of the new CPU cores, the Kyro 385 CPU is made up of four Cortex-A75 high performance cores (clocked up to 2.8GHz) and four Cortex-A55 efficiency cores (clocked up to 1.8GHz). In terms of frequency, the high performance cores can now clock much higher than those on the Snapdragon 835 (which typically top at 2.45GHz) and the combination of the new cores and higher clock speeds nets the high performance cores up to 30 percent performance uplift.
One thing to note is that unlike a fully customized Kyro core, Qualcomm has chosen to use much of the stock Cortex A75 and A55 core combination from ARM. Apparently, they are quite optimized to execute non-ARM code under emulation, which Cristiano Amon (EVP and President of Qualcomm Technologies) has stressed that they’ve worked with Microsoft over two years to ensure there is no perceivable penalty issue while executing Windows 10 OS and its legacy apps. This is good news since the Snapdragon 835 and now the 845 are targeted at a new breed of always-on, always-connected notebooks running Windows 10. Of course we’ll put those claims to the test, but for now, we’ll just have to wait it out till the first of these devices hit retail from the likes of the ASUS NovaGo and HP Envy x2.
