Neural networks can work quickly even on smartphones. Qualcomm has optimized Stable Diffusion so that it runs very fast on Snapdragon 8 Gen 2
Qualcomm showed the world’s first example of the operation of the Stable Diffusion neural network on an Android smartphone with data processing directly on the mobile device.
The Qualcomm AI Research team performed a full-featured AI optimization using the Qualcomm AI Stack to implement Stable Diffusion on a smartphone. Thanks to this, a 512 x 512 pixel image is generated in less than 15 seconds, which is very fast considering the performance of a smartphone. Which smartphone was used is not specified, but it was based on the latest Snapdragon 8 Gen 2 SoC.
For comparison, on the Web you can find an experiment on running Stable Diffusion on a Sony Xperia 5 II smartphone with a Snapdragon 865. In this case, it took an hour to create the same image! There is also a more correct comparison with the iPhone 13. The fact is that Apple previously released the optimizations necessary for the local launch of Stable Diffusion, but in this case the process took about a minute, so Qualcomm’s achievement and Snapdragon 8 Gen 2 performance are still the best in this direction.
New camera phones Oppo Find X6 and Find X6 Pro immediately became bestsellers
As expected, Oppo’s Find X6 and Find X6 Pro flagship smartphones launched today have become instant hits in China.
The published official Oppo posters confirm that the Oppo Find X6 and Find X6 Pro have become the best-selling Android devices on the popular Jingdong and Tmall platforms. As usual, the manufacturer does not provide any specific sales figures.
Recall that the flagship Oppo Find X6 Pro is offered at a price of $870 for the version with 12/256 GB of memory up to $1020 for the version with 16/512 GB. The basic version (no Pro in the name) costs $655-$730.
Oppo Find X6 Pro with its camera system will claim the title of the best DxOMark camera phone, but the review has not yet been published.
Satellite communication and “space” price. Huawei Mate X3 foldable smartphone unveiled
Huawei today unveiled not only the Huawei P60 line, but also the next generation of the foldable smartphone, the Huawei Mate X3. The new model received several significant differences from its predecessors at once.
Features include Beidou two-way satellite, ultra-thin tempered glass, reduced size and weight, water resistance (IPX8), and wet-hand touch mode.
The smartphone is equipped with a 7.85-inch internal flexible screen (2496 × 2224, LTPO, 120 Hz) and a 6.4-inch external display (LTPO, 120 Hz, Full HD + 2504 × 1080 pixels), a main camera (50 MP with optical stabilization , 13MP ultra-wide and 12MP telephoto with 5x zoom), 8MP selfie camera.
The hardware basis was SoC Qualcomm Snapdragon 8 Plus Gen 1 4G, from 256 GB to 1 TB of flash memory. The 4800mAh battery supports 66W wired charging and 50W wireless charging.
The smartphone weighs 239 grams, which is quite a bit for such a form factor, and the unfolded thickness is 5.3 mm. The hinge can be fixed at any angle, that is, the smartphone can be used in a partially open state. The operating system HarmonyOS 3.1 is installed on the smartphone.
The smartphone can already be ordered in China at a price of 12,999 to 15,999 yuan, which in terms of dollars now ranges from 1,903 to 2,343 dollars. Open sales will start on April 7th.
Advanced XMAGE camera, IP68 protection, heavy-duty Kunlun glass. Huawei P60 and P60 Pro unveiled, world’s first two-way satellite smartphones
Huawei today introduced its new flagships P60 and P60 Pro. The novelties turned out to be very interesting – in many ways they differ from the flagships of other companies.
The Huawei P60 features a 6.67-inch 4-sided OLED screen with a resolution of 2700 x 1200 pixels, a frame rate of 120Hz and a PWM frequency of 1440Hz. Interestingly, the Huawei P60 Pro has exactly the same display. As a result, the dimensions of both flagships are exactly the same, the difference is only in weight: the Pro version is several grams heavier. The screen is protected by ultra-strong Kunlun glass. And the phones are protected from external influences in accordance with the degree of IP68.
The cameras of the P60 and P60 Pro differ in that Huawei did not pursue megapixels – the maximum resolution (of the main sensor) is only 48 megapixels. This approach strongly resembles Apple’s approach to designing iPhone cameras.
The Huawei P60 camera is represented by three modules. The main one has a 48-megapixel sensor with an RYYB pixel layout, an F / 1.4-4.0 variable aperture lens and an optical stabilization system. The ultra wide-angle module has a 13-megapixel (RYYB) sensor and an F/2.2 lens, but no optical stabilization. Finally, the third module is responsible for 5x optical zoom, it uses a 12-megapixel sensor (RYYB) and has optical stabilization.
The first two modules of the Huawei P60 Pro are exactly the same as those of the younger model, but the module responsible for the optical zoom is different. Firstly, the resolution is higher – as much as 48 megapixels (apparently, exactly the same sensor is used here as in the main module), and secondly, there is just a huge aperture for the periscope module – F / 2.1. Therefore, pictures taken with optical zoom look as bright and saturated as pictures taken with the main camera.
This is how examples of photos taken with the Huawei P60 camera look like:
The parameters of the power subsystem for Huawei P60 and P60 Pro are the same: the phones received batteries with a capacity of 4815 mAh, support 88 W wired charging and 50 W wireless power.
The difference from the Galaxy S23 is that the P60 and P60 Pro come with an appropriate power supply, and with two ports at once: USB-A and USB-C.
Huawei P60 and P60 Pro became the first phones from the manufacturer with HarmonyOS 3.1 out of the box. And they are the first in the world to support two-way satellite communications: using the Chinese Beidou satellite system, you can not only send messages, but also receive them. In fact, satellite communication is already a real alternative to cellular, although there are still restrictions on sending messages and calls using satellite.
Interestingly, Huawei has not yet declassified the P60 / P60 Pro hardware platform and did not talk about prices. We will update the news as soon as this data becomes available.
