LiDAR scaner

What is a LiDAR scanner and what function does it perform on the iPhone 12?

What is the LiDAR scanner present on the iPhone 12 Pro and Pro Max?

With the new iPhone camera, Apple promises three things: photo and video effects, augmented reality, and scanning of objects and spaces. The last two go mainly to developers and businesses who are looking to create visual maps.

[td_block_ad_box spot_id=”custom_ad_2″]

But a general user will be satisfied with the photo and video effects. What is the LiDAR scanner present on the iPhone 12 Pro and Pro Max? Beyond its application in augmented reality, the LiDAR sensor works by emitting lasers that measure distances. On the iPhone 12 Pro and Pro Max Apple is using it to improve autofocus. The company says that as a result the autofocus is 6 times faster in low light compared to a normal camera. The LiDAR sensor also enables better quality portrait photos in low light conditions. The concept of using a dedicated depth sensor is not new.

Many phones use depth sensors to improve the quality of portrait photos and we can mention OnePlus Nord. But these sensors work mainly in light environments. Some models like the Huawei P30 Pro and Samsung Galaxy S20 Ultra have a time-of-flight (ToF) sensor which uses infrared to read the field depth.

Both ToF and LiDAR scans the environment several meters away, but some versions of the latter measure the distances up to 100 meters. Usually, such sensors are used in cars. The advantage of the LiDAR scanner is that it sends small pulses of beam from one corner to the other to scan the environment. While ToF sends only one light pulse to measure space compromising accuracy.

Implementing a LiDAR sensor on the iPhone, developers will most likely be encouraged to find ways to use it primarily in augmented reality. Snapchat became the first app to launch lenses for the iOS app that uses LiDAR.

Apple 5nm Chip-

Apple today will show more than the iPhone 12, a technological revolution

Today the company will make a fuss with the first devices that have a new type of chip

With the new processor, users of these devices can edit 4K video, modify high-resolution photos, and play graphically intensive games more easily than previously possible using fewer battery.

[td_block_ad_box spot_id=”custom_ad_2″]

The new 5-nanometer architecture means that the size of the transistors has been reduced and the processor board occupies more of them than was previously possible. These transistors are now only 25 atoms wide and billions of them can be placed on a single plate. Simply put, more processing power. Four years ago the industry doubted that such an advancement would be possible.

Such advancements would not have been possible before an unknown Dutch company called ASML. This company has developed a way to construct transistors on the silicon plate through a process called Extreme Ultraviolet (EUV). Its machinery costs $123 million a share. It is currently the only company that manufactures these devices and they are more cost-effective than alternative options due to the low level of defects.

Only two chipmakers have started using this technology commercially:

Both firms have their share in ASML alongside Intel which will start using the technology in 2021.

What exactly does 5-nanometer mean?

One nanometer is one of 1 billion Metter. This is the size that human hair grows every second. Transistors are used to measure the width of a component. But a decade ago the way chips are designed changed and nanometers are no longer used as a geometric effect. Today 5 nanometers is more of a marketing term and two companies with the same design can produce transistors with different performance.

To help you understand the size of transistors, at every 1 mm2 of the Apple chip are put 17,1 million transistors. The new structure with a stack of four nanosheets allows about 30 transistors to be placed onto the chip with the size of a fingernail bringing significant gains in efficiency and power.

In comparison to the 10 nm chip, the new 5 nm structure brings 40% performance improvements at fixed power, or 75% power saving at matched performance. This leads to more powerful and more efficient smaller devices.

N5 is the first TSMC process designed around extreme ultraviolet lithography (EUV). Because it uses a 13.5-nanometer light instead of 193-nanometers, EUV can define chip features in one step—compared with three or more steps using 193-nanometer light.

Smarter smartphones

Everything that was said above matters because switching to 5-nanometer means that devices are more intelligent. As chips advance, more tasks are capable of performing and many of them can now be done locally instead of being sent to remote servers. We have already seen smartphones capable of transcribing voices or recognizing people in pictures without the need for an internet connection. With new processors, more complex tasks are possible with artificial intelligence which means that smartphones can better recognize the world around them.

Switching to smaller transistors, processors use less power and have higher performance. For this reason, TSMC 5-nanometer chips should be 15% faster than 7-nanometer ones or 30% more power-efficient.  Apple claims that the A14 can perform machine learning tasks 10 times faster than the A13. But consumers are more concerned about real-life benefits than theoretical digits.

iPhone 12 Last Minute Rumors: Better Zoom and Longer Battery Life

Apple will unveil new iPhone models today. The company will hold an event at 19:00 with our local time and you can watch the live broadcast live on this YouTube link. With the Apple event just a few hours away, you would think that we already know everything about the new iPhone 12. And, for the most part, we know, and here are two summaries of what we expect for Apple to announce tomorrow.

[td_block_ad_box spot_id=”custom_ad_2″]

According to speculation, Apple will introduce four versions of the iPhone 12, including a 5.4-inch “mini” model, an iPhone 12, 12 Pro, and 12 Pro Max. Some of the models will be equipped with 5G technology although the latter is still in experimental stages in many parts of the world.

However, the leaker Max Winebauch has disseminated some very detailed, last-minute information about the new iPhones, some of which we have not heard before.

According to Winebauch, the smallest of the iPhone, the 5.4-inch “iPhone 12 Mini” – will have a TrueDepth camera system adjusted at the front, resulting in a level that is smaller horizontally but slightly larger vertically.

Zoom is getting another improvement; Weinbauch claims that the Pro models will have 3x optical zoom and 25x to 30x digital zoom, while the non-Pro iPhone 12 models will get better zoom through software upgrades.

The new iPhones are getting bigger batteries than the previous models. This should result in one-hour battery life for Pro models. However, the 5.4-inch iPhone 12 Mini will perform worse than the iPhone 11 when it comes to battery life, due to its smaller size.

Other news from Weinbauch includes support for 4K video at 120 or 240 fps, faster Face ID operation, night mode being added to the telephoto camera, better low light performance for the ultrawide camera, and a possible macro camera mode, as well as a portrait video.

The big Apple event starts at 19:00, on Tocday, October 13th.

How to follow the iPhone 12 live presentation?

Apple will introduce new iPhone models today. The company will hold an event at 19:00 with our local time and you can watch the live broadcast live on this YouTube, or through the video below.

Apple will also introduce a wireless charging device. The iPhone giant has also long been reported to be working on a pair of headphones that will join the AirPods line. As we said above Apple will broadcast the activity live on YouTube and it is the easiest way to watch it.

AMD Zen 3 Desktop CPUs

AMD Zen 3 5000 series Desktop CPUs Officially Revealed

How would be able AMD to create a third successful Ryzen 9 processor? Last year it was clear that the company had brought a real challenge to Intel especially in video game performance. With the new Zen 3 architecture, AMD went the illustrations once again to create a processor and platform which is more efficient. The company even got more turbo frequencies and 19% more (IPC) showing real performance.

[td_block_ad_box spot_id=”custom_ad_2″]

The Ryzen 9 5900X debuts on 15 November is a 12-core 24 threads chip with 4.8Ghz turbo frequency, 64MB L3 Cache and 105-watt thermal design. AMD says the 5900X offers 26% more gaming performance than the Zen 2. Specifically, it has increased performance per core where AMD has faced difficulties. The company says it is the first processor to go beyond 600 points in the Cinebenc R20 1T benchmarks with 631 points. The Core i9-10900K processor scores 544 points even though it has a higher frequency.

Ryzen 9 5900X

The rest of the 5000 line is a model Ryzen 5800X with 8 cores and one with 6 cores the Ryzen 5600X that sell for $449 and $299 respectively.

Lastly, the company had maintained a surprise, the Ryzen 5950X model with 16 cores and 32 threads as well as 4.9Ghz turbo frequency while maintaining the same thermal design of 105-watt starting at $799. It is the ideal solution for those who want the performance of a Threadripper but at a much lower cost.

What makes Zen 3 special? Redesigned design creating a unified 8-core complex that reduces instruction delays and allows cores to reach the processor L3 Cache itself. The results of this design will be felt mainly in games and their online streaming like Twitch. Overall Zen 3 is 24% faster than Zen 2 and 2.4 times faster than Zen 1. AMD said the company is currently working on the Zen 4 5-nanometer architecture.

Meet the OnePlus 8T design before its debut

OnePlus will officially unveil the 8T on October 14th

In a video released yesterday, OnePlus has revealed the full design of the OnePlus 8T ahead of its official debut. The design is very different from its OnePlus 8 predecessor. So the company has decided to move away from the central camera module for a module located in the upper left corner.

[td_block_ad_box spot_id=”custom_ad_2″]

It’s a surprise because OnePlus has been using the central camera design for several years. At first glance, the OnePlus 8T is very similar to the affordable OnePlus Nord model. The green color inherited from the flagship models of the year will remain. OnePlus will officially introduce the 8T on October 14th.

The phone is confirmed with a 65W fast charger, a new camera sensor, 120Hz flat screen.

The first DDR5 RAM modules unveiled by SK Hynix

DDR5-4800 chips have speeds between 4,800 to 5,600Mbps while consuming less power than DDR4

Korean chipmaker SK Hynix introduced the first 64GB DDR5 RAM module, marking a big step compared to DDR4 DIMMs which have dominated computer memory since 2013. DDR5-4800 chips have speeds between 4,800 to 5,600Mbps while consuming less power than DDR4. The technology also makes possible 256GB modules available in size.

[td_block_ad_box spot_id=”custom_ad_2″]

The JEDEC standard of DDR5 RAM was officially introduced in July but SK Hynix has unveiled the first chip in 2018 with this memory. In addition to capacity, DDR5 will have two 32-bit channels instead of 64-bit making it easier to increase the bandwidth. It is the modules themselves that regulate the voltage and not the board with DDR5 allowing the memory output to control its frequency. SK Hynix also tested the modules at 6,400 Mbps and 8,400 Mbps.

By 2022 DDR5 memory will occupy only 10% of sales and by 2024 it will go to 43%. When this moment comes it will be the de facto the memory used on all new computers.

RTX A6000

The RTX A6000 and A40 are twice as powerful as the RTX 3090

The RTX A6000 goes on sale in mid-December while the A40 next year

Nvidia has a solution for professionals to get the Ampere architecture: RTX A6000 and A40. These two cards easily break the hegemony of the RTX 3090 with 10,752 CUDA cores and 48GB VRAM.

[td_block_ad_box spot_id=”custom_ad_2″]

They come to succeed the RTX Quadro 8000 and 6000 series. It is not known why Nvidia did not use the Quadro branding this time. The company did not go into the details of the frequencies but you can see them as a more powerful version compared to the RTX 3080 and 3090. The A40 model is passively cooled and has a memory frequency of 14.5Gbps.

Google Pixel 5

Google Pixel 5 and 4a 5G officially revealed

The Pixel 5 costs $699 while the Pixel 4a 5G starts at $499. The standard non-5G Pixel 4a costs $399

Finally confirming everything, Google has decided to look the market from another angle and strives to offer flagship quality at more affordable prices. With the latest line of Pixel phones unveiled on Wednesday, Google decided to pull out of the big smartphone battle by focusing more on the consumer and budget models than the Premium segment dominated by Apple and Samsung with smartphones costing over $1,000.

[td_block_ad_box spot_id=”custom_ad_2″]

The Pixel 5 costs $699 and the Pixel 4a 5G starts at $499. The standard non-5G Pixel 4a costs $399. These low normal prices have their cost because both phones have less powerful processors and not as a high-quality screen as the high ranking Samsung and Apple phones.

Both phones come with 5G technology. Pixel 5 is powered by a Snapdragon 765G processor which is a step below the Snapdragon 865 or 865 Plus but accompanied by Qualcomm’s X52 5G modem. It’s a big twist on Google’s usual Pixel strategy. Pixel 5 differs from 4a in IPX8 resistance, wireless charging of devices, more RAM, higher quality Gorilla Glass 6.

The 6-inch OLED screen with a resolution of 2,340 x 1,080 pixels (432 ppi) of Pixel 5 will be full HD+ and will have a modest refresh rate of 90Hz. RAM up to 8GB, 128 GB of storage, 4080mAh battery with 18W USB-C fast charging, and against what was thought will support both sub-6Ghz but also mmWave 5G. As expected, the fingerprint sensor will be on the back of the device. 

Like the Pixel 5, the Pixel 4a has a Qualcomm Snapdragon 765G processor. The Pxiel 4a 5G battery has been upgraded compared to 4a and comes with an output of 3,885 mAh.

A wide-angle camera

The strong point will always remain the camera which despite having only two sensors one 12MP with 77 degrees of field of view and another 16MP with 107 degrees its software will lift the most weight. Thus, new AI-powered options are Portrait Light, Cinematic Pan, and three new video stabilization modes. The front camera has an 8-megapixel sensor and offers portrait mode but also Night Mode.

The camera should be able to record full HD video at 240 fps and 4K video at 60 fps. With improved timing and slow motion as well as image stabilization, better video quality should be achieved.

With the new models Google will address a major user concern, battery life. The new Extreme Battery Saver mode will increase battery life by up to 48 hours leaving only vital applications running. This mode will also be offered for older Pixel models.

A cheap price

The Pixel 4a 5G will cost $499, the Pixel 5 will be cheaper than its predecessor and should only cost $699. The Pixel 4a 5G should be available from October 15 in Japan and from November in 8 other countries. The Pixel 5 will also launch on October 15, at least in the US.
