Intel has updated the performance of the Arc A750 graphics processing unit (GPU) optimized for gaming. Game graphics performance is improved by up to 77% through software improvements.

Intel announced on the 18th that the Arc A750 pushed for an update to support optimized gaming in various environments such as Direct 9 (DX9). DX is a comprehensive multimedia library of Microsoft (MS) and is necessary to optimize the gaming environment.

Previously, in October of last year, Intel released the GPU ‘Arc A750’, which focuses on high performance, efficiency, and scalability for cutting-edge content production. At the beginning of the release, we focused only on the DX12 environment, which is mainly used by the latest games.

Graphics processing such as rendering in the DX9 or DX11 environment was evaluated as relatively inferior. As a result of the actual benchmark test, in the DX9 environment, it was found that the performance was inferior to the equivalent GPU products of competitors such as NVIDIA and AMD.

Intel this time standardized the average frame rate (FPS) of the Arc A750, leading to an average graphics performance increase of 43% per DX9 game. Compared to the previous version, StarCraft 2 improved by 31%, League of Legends (LoL) by 45%, Lost Ark by 51%, and CS:GO by 77%.

The price was set at around 330,000 won ($249), maintaining price competitiveness compared to NVIDIA and AMD equivalent GPUs. Gaming performance in the DX11 environment has also been improved.

Intel supports checking the performance of the central processing unit (CPU) and GPU through ‘GPU Busy’. System semiconductor performance, such as CPU frame time and GPU rendering operation time, can be analyzed and replacement time predicted.

The PresentMon service, which is specialized for arc testing, will also be officially launched on the 21st. It provides gaming PC balance metrics, integrated GPU telemetry/capture, various software/open source and extensive application program interfaces (APIs).

It has been suggested that a rock found in the Sahara Desert in Morocco several years ago may be a so-called ‘boomerang meteorite’ that fell from Earth to space and back to Earth.

According to Space.com, a space media outlet, on the 24th (local time), research results suggesting the possibility of a ‘boomerang meteorite’ were announced at the International Geochemistry Conference last week.

The rock the researchers paid attention to is the meteorite ‘Northwest Africa 13188’ (NWA13188), which was discovered in the Sahara Desert in Morocco in 2018.

Weighing 646 grams (g), the stone block NWA13188 has the same chemical composition as Earth’s native volcanic rocks. But at the same time, some elements left traces like meteorites found in space.

Most meteorites are exposed to radiation ‘cosmic rays’ from space, so the isotope concentrations of beryllium-3, helium-10, and neon-21 are different from rocks on Earth. NWA13188 has the highest isotope concentration of any rock on earth Confirmed. However, the concentration was lower than that of ordinary meteorites.

Also, in NWA13188, a fusion crust observed on the outer surface of the meteorite was discovered. When a meteorite passes through the atmosphere at high speed, the surface melts and falls apart due to friction, and at this time, a thin glossy shell is formed on the outermost part of the meteorite. This is called the melting angle.

In a word, it has all the elements of a meteorite, but at the same time, it means that it has a chemical composition that can be seen on Earth.

The researchers speculate that NWA13188 may have flown from Earth into space when an asteroid hit Earth 10,000 years ago, and may have spent more than 2,000 years in Earth’s orbit before entering Earth’s atmosphere.

However, the results of this study have not yet been published in a peer-reviewed journal that has been evaluated by academic experts.

The problem is the meteorite’s age. The NWA13188 meteorite is classified as an ungrouped achondrite, which is usually expected to have formed 4.5 billion years ago. However, if NWA13188 was sent from Earth, it must have been created more recently.

Also, if the impact is enough to blow this meteorite from the Earth into space, it is more likely to be an asteroid impact than a volcanic eruption, but no crater created 10,000 years ago has been confirmed. Of course, there are dozens of craters on Earth that still need to be verified, so the possibility cannot be said to be zero.

“10,000 years ago is a very recent occurrence, and it must have been discovered,” said a curator specializing in rocks at the Natural History Museum in Vienna, Austria. ) pressure and temperature increase explosively. A crater that created an impact like this would still be hot,” he said.

There was a prospect that the iPhone 15 could be released in a gorgeous pink color.

According to foreign media, there was light pink in the series before the iPhone 15, but there was no flashy pink.

This iPhone 15 is expected to be released in green and yellow, including gorgeous pink. Looking at the iPhone 15 Pro model color outlook, the iPhone 15 series colors can also be released in red, starlight, and midnight colors.

Looking at the iPhone 14 color lineup, there were blue, purple, and dark yellow. If the iPhone 15 color forecast is correct, the colors that were seen on the iPhone 14, such as blue, purple, and dark yellow, cannot be seen on the iPhone 15.

It’s been a year since the James Webb Space Telescope (JWST; Webb) released four pictures to the public.

During the 12 months that the Web published the photos, the general public was amazed at their ability to capture even the tiniest of light, and the scientific community cheered for an unexpected discovery.

On the 12th (local time), the American media Business Insider compared and analyzed the astronomical photos taken by Webb with those taken by Hubble, a space telescope, in celebration of the first anniversary of the release of Web photos.

Rings of Uranus… Web caught 11 in just 12 minutes

In April, the National Aeronautics and Space Administration (NASA) released new photos of the icy planet Uranus in the solar system.

Farrani’s glowing Uranus was similar to the one taken by Hubble, but above all, attention was drawn to the sharp rings surrounding it. Although Uranus has rings like Saturn, it is difficult to capture with a space telescope because it is made of rock and dust that does not reflect sunlight.

In 1986, NASA’s Voyager 2 probe and the Keck Observatory teamed up to discover the first two rings, but this was due to Voyager 2’s proximity to Uranus.

Hubble also photographed the two outermost rings in 2022, but Webb clearly captured 11 of the 13 rings in just 12 minutes of filming.

Sharp infrared eyes to Jupiter auroras and storms

Last August, Webb set his sights on Jupiter, the largest planet in the solar system.

The Great Red Spot, a giant storm, and the streaks across the planet were as known to mankind, but the polar regions were different.

Webb’s image of Jupiter shows its poles glowing. Jupiter, which has a magnetic field 20,000 times stronger than Earth’s, produces the most powerful auroras in the solar system.

On the other hand, the reason why Jupiter, which had only been seen in ocher color, appeared blue to Webb’s eyes was not in visible light like Hubble’s, but because it synthesized three pictures taken with a near-infrared camera (NIRCam) with three special infrared filters of red, yellow-green, and blue. .

The Southern Ring Nebula “really had two stars in the center”

<웹의 중적외선 장비(MIRI)으로는 중심에 별이 2개라는 것을 더욱 선명하게 볼 수 있다. 사진=NASA, ESA, CSA, STScI>

The Southern Ring Nebula, also known as the Eight-Burst Nebula, was one of the first images published by Webb on July 12 last year.

In the Southern Ring Nebula, a dying star continues to ripple and push dust outward. Scientists knew there were two stars at the center of the nebula, but to Hubble the single star appeared like a small dot.

However, when observed through the web, two stars in the center of the nebula clearly shined. Also nearby were three stars shining in a nebula. Even the long-gone light was captured by Webb’s sharp eye.

The ‘Scattering Field of Stars’ reveals the true value of the web

Webb’s sharp field of view can be confirmed when shooting the so-called ‘star scattering field’ where new stars are born.

Stars are usually born surrounded by a thick layer of cosmic dust and gas, and the webs penetrate this thick ‘cocoon’ and capture even faint light clearly.

This can be seen in the Carina Nebula. The Carina Nebula was also included in the first picture released last year. In particular, the upper left of the image is where young stars are forming. Numerous stars that were invisible when taken by Hubble have made their presence felt in images from the Web.

In 20 hours, to the distant light hidden in a black space

Deep field, one of the first five chapters published by Webb. This deep field, Hubble’s first attempt, refers to taking pictures of outer space where nothing can be seen.

The Ultra Deep Fields, taken in 2003 and 2022 by Hubble and Webb, respectively, look similar at first glance. However, it made a huge difference in time. These huge space telescope projects are literally ‘time is money’. An astronomical amount of money goes into operating it for just one day.

In 2003, Hubble took just 11.3 days to complete this image. It was obtained by taking 800 images during Hubble’s 400 orbits around the Earth. On the other hand, Webb proved its performance by taking photos that surpassed those of Hubble in just 20 hours.
