DDR5 benchmarks show how much faster new RAM will be

Published

on

Video cards are becoming noticeably more productive every new generation. AMD has convinced us in recent years that this can be a normal situation in the processor market as well.

But not only these components can receive an increase in the speed of work with the transition to a new generation. The Chinese company Longsys has published tests of its own DDR5 RAM. In this case, the Intel Alder Lake platform was used, which will just receive support for such memory.

The memory modules used in the test had a frequency of 4800 MHz and CL40 timings (40-40-40-77). Two-rank modules were tested.

As a result, in the Master Lu benchmark, the platform with DDR5 memory scored 190,000 points in the corresponding subtest, while the system with DDR4 memory scored less than 92,000 points, that is, more than half.

In the AIDA64 benchmark, the platform with the new memory performed 28%, 27% and 10% better than the DDR4 system. In this case, we are talking about read, write and copy tests, respectively.

It should be noted that we were talking about engineering samples of DDR5 modules.

The multimedia system of the Lexus NX car uses the single-chip systems Renesas R-Car H3 and R-Car M3

Published

on

Renesas Electronics has announced that its R-Car H3 and R-Car M3 SoCs have been selected by Toyota Motor for the next generation of car multimedia systems. Toyota’s next-generation multimedia system will debut for the first time in the Lexus NX, scheduled for release in November 2021. It is planned that these systems will be installed in other cars of Lexus and Toyota brands.

Toyota’s next-generation infotainment system includes a high-definition widescreen widescreen touchscreen display up to 14 inches. The display area can be flexibly divided into sections and zoomed in and out, taking advantage of a combination of advanced functionality and convenience. The system has voice recognition features such as quick start in response to voice commands, car sound system, and over-the-air (OTA) software updates.

Renesas’ R-Car single-chip systems provide the ability to import map information, images and video from user devices, including smartphones, and output to a large display. They are also responsible for functions such as touchscreen display control, voice recognition via microphone input, and audio output to multiple speakers. In addition, the built-in security features of the SoC R-Car are entrusted with secure OTA software updates.

Since the functions of the multimedia system differ depending on the car model, Toyota uses the R-Car H3 in systems for the more expensive models with the maximum equipment, and the SoC R-Car M3 can be found in other car models.

TSMC presented the N4P process technology

Published

on

TSMC introduced the N4P process, a performance-optimized enhancement to the 5nm technology platform. New process technology added to N5, N4, N3. According to the manufacturer, the choice between them gives customers the opportunity to choose the most suitable combination of power consumption, performance, die area and product cost.

The new process technology is the third major improvement on TSMC’s 5nm platform. The company estimates that N4P delivers an 11% increase in productivity over the original N5 technology and 6% over N4. Compared to N5, N4P will also provide 22% more energy efficiency and 6% more transistor density. In addition, N4P reduces process complexity and shorter insert cycle times by reducing the number of masks.

N4P projects are said to be well supported by TSMC’s comprehensive design ecosystem. The first products based on N4P technology are expected to go into production by the second half of 2022.

Xturismo Flying Motorcycle Orders Started in Japan

Published

on

The Japanese company ALI Technologies has presented the “flying motorcycle” Xturismo, capable of speeds up to 100 km / h and stay in the air for up to 40 minutes. During the demonstration, the device rose several meters above the ground and flew for about one and a half minutes. The weight of the device, designed to carry one person, is 300 kg.

ALI Technologies, backed by Kyocera and Mitsui Sumitomo Insurance Venture Capital, has already started accepting orders and plans to begin shipping the first batch of 200 pieces in the first half of next year. The Xturismo is priced at approximately $ 682,000.

Interestingly, in the Xturismo, the main propulsion system does not use electric motors, but an internal combustion engine that drives the two main propellers. Auxiliary propellers help maintain balance and perform maneuvers. To do this, the “motorcycle” uses technology tested by ALI in drones.

One of the applications of the apparatus is called rescue operations on the water. True, it is not clear how exactly the assistance is supposed to be provided – neither the carrying capacity, nor the cruising range, nor the lack of the possibility of landing on water contribute to such an application, not to mention the fact that for aircraft operated over water, it is mandatory to reserve engines with the ability to continue flight if one of them fails.
