Science and Technology Morning Post: Apple Vision Pro is controversial | Zhiji L6 is expected to be launched in Q2 | Qicaihong RTX3050

1. Apple Vision Pro is controversial

Recently, Apple launched Vision Pro, which caused controversy. Some users wore Vision Pro to drive and chose to turn on Tesla's automatic driving mode.

To sum up, wearing Vision Pro while driving is a dangerous behavior, which may distract the driver's attention and increase the risk of traffic accidents. Even if the automatic driving mode is turned on, the driver should be alert and ready to take over the control of the vehicle at any time.

3. Volkswagen cooperates with Xiaopeng Automobile to develop two new models

Volkswagen Group and Xiaopeng Auto officially announced that they will jointly develop two new electric models for the Chinese market and plan to start production in Hefei in 2026. Previously, Volkswagen had invested $700 million in Xiaopeng Auto and obtained 4.99% of the latter's equity.

This cooperation project will be implemented by Volkswagen (China) Technology Co., Ltd. (VCTC), which is located in the intelligent connected vehicle industry cluster in Hefei. Volkswagen Anhui Factory and Volkswagen (Anhui) Parts Co., Ltd. also operate in this region.

"We are very proud to announce that the cooperation project between Volkswagen and Xiaopeng has settled in Hefei."

4. NVIDIA uses AI technology to turn ordinary video into HDR

NVIDIA recently released an“ RTX Video HDR technology, which can transform the dim SDR Video conversion HDR video is highlighted. This new technology uses the Tensor tensor core and AI technology of RTX 20/30/40 series graphics cards, which can upgrade network video to HDR and improve the effects of color, contrast and brightness.

In NVIDIA's research, a user named "NvTrueHDR" created a corresponding MOD to automatically upgrade SDR games to HDR games. Similar technical principle is to use the RTX GPU Tensor core to improve the color and brightness of the game, especially the earlier DX11 DX12 games.

According to the measured results of netizens, the effect of "NvTrueHDR" is much better than the AutoHDR that comes with Windows, and some people even think that it can compete with the native HDR image. However, it should be noted that the use of this technology may lead to performance loss, but there is no specific figure to describe it.

In addition, "NvTrueHDR" currently only supports Windows operating system, and requires drive The program version shall not be lower than 551.23. This technology is still in the testing stage, so it is recommended to try carefully.

5. Seven Rainbow RTX 3050 video card: 1399 yuan

Qihonghong has launched two RTX 3050 graphics cards on JD, namely Tomahawk DUO and Smart Mini. The price of these two graphics cards is 1399 yuan.

It is also equipped with double 90mm fans and supports intelligent start stop technology.

RTX 3050 is a low-end video card with 2304 CUDA cores, 6GB video memory and 70W TDP. Compared with the previous version, its video memory bit width is reduced from 128bit to 96bit, which directly reduces the bandwidth to 168GB/s. Other performance indicators have also decreased.

This graphics card is suitable for light games and general graphics processing needs, and the price is relatively friendly. If you need a higher performance graphics card to run large games or perform complex computing tasks, it is recommended to choose a higher end product.

6. Other information

It is reported that the release date of Apple Cars has been postponed from the previous expectation to 2028. This project has been under preparation since 2014, and has gone through many changes of leadership, layoffs and strategic adjustments. It is one of the largest businesses in Apple's history. Although autonomous cars have always been one of Apple's core investment areas, the company invests a lot of money every year in research and development of salaries, cloud system control autonomous computers, road testing and other aspects, but there are no related products on the market at present. Therefore, the market's attitude towards Apple Auto has gradually returned to rationality.

It is reported that Phil Spencer, the CEO of Xbox, will release details about the future planning of the brand next week. This has triggered some speculation, which may be related to the recent widely circulated news that the first party game under Xbox may land on the PlayStation platform. Therefore, some people believe that Xbox may give up the exclusive strategy and turn to the development direction of multi platform strategy.
