Realme GT Neo 5 specs have been revealed with incredible surprise!



Realme GT Neo 5 specs have been revealed with incredible surprise!

Realme remains one of the most famous Android smartphone manufacturers, especially since it has managed to grow incredibly since its launch just a few years ago. More information about one of the upcoming Realme GT Neo 5 devices is now emerging.

One aspect where the Chinese manufacturer excels is in the charging capacity of its smartphones, which becomes evident when we look at the GT Neo 3, the first on the market with 150W fast charging.

We have now learned that the company may take this capability to the next level when the Realme GT Neo 5 hits the market with a 4600mAh battery and 240W charging power. If this information is confirmed, it will be the first smartphone with such a high charging capacity to hit the market.

Interestingly, Oppo has shown the possible results of this combination in the past. According to a demonstration held during Mobile World Congress 2022, a 4500mAh battery charged with 240W can reach 100% in just 9 minutes.

As for the other specifications of the Realme GT Neo 5, we only know that it should be equipped with a Sony IMX890 main sensor with support for optical image stabilization.

ASUS Confirms Radeon RX 7900 XTX/XT TUF Gaming Clock Speeds



ASUS Confirms Radeon RX 7900 XTX/XT TUF Gaming Clock Speeds

ASUS Radeon RX 7900 Series TUF Gaming Specifications Become Official

ASUS has become the first motherboard partner to fully confirm clock speeds for dedicated Radeon RX 7900 GPUs.

As reported last month, ASUS became the first company to introduce dedicated Radeon RX 7900 GPUs. These TUF gaming cards are based on the 7900 XTX and RX 7900 XT drives with a custom three-fan design for 3.6 slots, and also feature three 8- power connectors. ASUS has already confirmed the clock speeds that will apply to each of the four announced models.

The official ASUS specification lists the so-called “standard” mode and “OC” mode. The latter is the highest official specification that ASUS software called GPU Tweak can apply. For this reason, it should not be regarded as an “unusual” specification, but as the highest officially supported certified clock speed, which will not affect the warranty.

As a reminder, the default gaming frequency of the Radeon RX 7900 XT is 2300 MHz, while the boost clock increases to 2500 MHz. For the Radeon RX 7900 XT GPU, these are 2000 MHz and 2400 MHz, respectively.

ASUS TUF Gaming Radeon RX 7900 XTX OC Edition

  • Modo OS:
    • up to 2615 MHz (clock frequency) +4.6%
    • up to 2455 MHz (game clock) +6.7%
  • default mode:
    • até 2565 MHz (Boost Clock) +2.6%
    • Up to 2395 MHz (game clock) +4.1%

ASUS TUF Gaming Radeon RX 7900XT OC Edition

  • Modo OS:
    • até 2535 MHz (Boost clock) +5.6%
    • up to 2175 MHz (game clock) +8.7%
  • default mode:
    • até 2500 MHz (clock frequency) +4.1%
    • up to 2130 MHz (game clock) +6.5%

The overclocked version of the Radeon RX 7900 XTX TUF Gaming GPU is clocked at 2565 MHz by default, which is 2.6% (increase) of the factory overclock. However, in OC mode, clock speeds are 4.6% faster than AMD’s claims. On the other hand, the RX 7900 XT TUF OC is slightly overclocked. By default, it runs at 2500 MHz, which is 4.1% higher than the specification, and in OC mode, a software overclock of 5.6% is applied.

The gaming clock is higher, but with proper cooling, the GPU is more likely to hit its clocks than the gaming ones. Overall, these performance improvements are similar to the Radeon RX 6900 XT TUF OC Gaming GPUs, but it’s worth noting that ASUS has a higher-end TUF TOP Edition with higher overclocking.

Gas giant exoplanet discovered, twice the mass of the Earth: ScienceAlert



Gas giant exoplanet discovered, twice the mass of the Earth: ScienceAlert

A recently suspended exoplanet has puzzled astronomers.

By taking measurements of a very small Jupiter-sized exoplanet called HD-114082b, scientists found that its characteristics do not match either of the two popular models for the formation of gas giant planets.

Simply put, he is too heavy for his age.

“Compared to currently accepted models, HD-114082b is two to three times denser for a young gas giant just 15 million years old,” he said. explains astrophysicist Olga Zakhazy from the Max Planck Institute for Astronomy in Germany.

This exoplanet, orbiting a star called HD-114082 at a distance of about 300 light-years, has been the subject of an intense data collection campaign. At only 15 million years old, HD-114082b is one of the youngest exoplanets ever discovered, and understanding its properties could provide clues to how planets form, a process that is not fully understood.

Two types of data are needed to comprehensively characterize an exoplanet based on its influence on the host star. The transit data is a record of how the light of a star dims when an orbiting exoplanet passes in front of it. If we know how bright the star is, this slight dimming could reveal the exoplanet’s size.

On the other hand, radial velocity data is a record of how much a star wobbles in response to the gravitational pull of the outer planets. If we know the mass of a star, the amplitude of its oscillations can give us the mass of an exoplanet.

For nearly four years, the researchers have been collecting observations of the radial velocity of HD-114082. Using data collected on transit and radial velocity, the researchers determined that HD-114082b has a similar radius. Jupiter – But the mass of Jupiter is 8 times greater. This means that the density of the exoplanet is almost twice that of the Earth, and about 10 times that of Jupiter.

The size and mass of this small exoplanet means it is unlikely to be a very large rocky planet; top borders around it 3 earth radius It’s in 25 earth masses.

Rocky exoplanets also have a very small density band. Above this range the body becomes more intenseAnd the planet’s gravity begins to contain an important atmosphere of hydrogen and helium.

HD-114082b significantly exceeds these parameters, which means it is a gas giant. But astronomers don’t know how it happened.

“We think that the giant planets could have formed in two possible ways.” says astronomer Ralf Lönnhardt mpiya. “Both occur within a protoplanetary disk of gas and dust distributed around a young central star.”

Both methods are called “cold start” or “warm start”. During a cold start, an exoplanet is thought to form, pebble by pebble, from the debris of a disk orbiting a star.

Parts are attracted to each other first electrostatically and then gravitationally. The larger the mass, the faster it grows until it becomes massive enough to cause the runaway accumulation of hydrogen and helium, the two lightest elements in the universe, creating a huge shell of gas around the rocky core.

Given that gases lose heat as they fall towards the planet’s core and form an atmosphere, this is considered a relatively cool option.

Hot start is also known as disk instability and is believed to occur when a swirling region of instability in the disk collapses directly on itself under the force of gravity. As a result, the object is a fully formed exoplanet without a rocky core, as the gases hold more heat.

Exoplanets that experience a cold start or a hot start must cool at different rates, leading to different features that we should observe.

The researchers say the performance of the HD-114082b is not suitable for a hot start model. Its size and mass are more consistent with primary accretion. Even so, he is still quite large for his size. Either it contains an unusual core, or something else is going on.

“It is too early to abandon the idea of ​​a hot start” Lennhardt says🇧🇷 “All we can say is that we still don’t quite understand the formation of giant planets.”

Exoplanets are one of three planets less than 30 million years old for which astronomers have obtained radius and mass measurements. So far, all three seem to be inconsistent with the disk instability model.

Three is clearly too small for the sample size, but three to three indicates that primary accumulation is probably the more common of the two.

“While more planets of this type are needed to confirm this trend, we think theorists need to start rethinking their calculations.” Zahozay says.

“It’s amazing how the results of our observations fit into the theory of planet formation. They help improve our knowledge of how these giant planets grow and tell us where there are gaps in our understanding.”
