SAPPHIRE's family of GPRO graphics card is usually found in workstations, but the new GPRO X080 and X060 are purely crypto-mining graphics cards. SAPPHIRE says that the GPRO X080 will give you 38MH/s on Ethash (Ethereum algorithm) with its default 165W TGP, while when optimized that will increase to 41.6MH/s for only 93W.

The SAPPHIRE GPRO X080 is based on the Navi 22 GPU with 2304 Stream Processors clocked at 2132MHz, it has an interesting allotment of 10GB GDDR6 memory on 160-bit memory bus and clocked at 16Gbps. The card requires a PCIe 4.0 x16 slot and only works with Linux. There are no display outputs on the card, so don't go thinking you can buy it and play Crysis.

Anthony Garreffa | Video Cards | Mon, Nov 29 2021 7:21 PM CST

Palit has just unleashed its beautiful and very unique new ColorPOP graphics card series, with the introduction of the new Palit GeForce RTX 3060 Ti ColorPOP graphics card.

The new Palit GeForce RTX 3060 Ti ColorPOP is a full-custom design with a 2.7-slot cooling solution, with Palit changing things up by rebranding their GamingPro series to the new ColorPOP series. The changes are extensive: new colors, new stickers, and of course; new packaging.

What is special here with the Palit GeForce RTX 3060 Ti ColorPOP is that it features beautiful color-shifting paint dabbed on its shroud and backplate, where the card will flex between different colors including green, violet, and blue when you look at it from different angles and lighting conditions.

NVIDIA GeForce RTX 3090 Ti confirmed: will rock Micron's 21Gbps GDDR6X

Anthony Garreffa | Video Cards | Mon, Nov 29 2021 6:37 PM CST

NVIDIA is currently preparing another flagship graphics card for a big unveiling in January 2022, with the purported GeForce RTX 3090 Ti graphics card that will rock Micron's even-more-ultra-fast 21Gbps GDDR6X memory.

The current flagship NVIDIA GeForce RTX 3090 arrives with 24GB of GDDR6X memory clocked at 19.5Gbps, but it easily overclocks to 21Gbps and barely offers any perceivable performance difference. But, the new GeForce RTX 3090 Ti will not only have upgraded GDDR6X memory (21Gbps vs 19.5Gbps) but with it, it'll have slightly more memory bandwidth at 1008GB/sec (1TB/sec) compared to 936GB/sec on the RTX 3090.

Inside, NVIDIA is expected to use the GA102-350 GPU which bumps up everything across the board: 84 GPU clusters (versus 82 on the GA102-300 inside of the RTX 3090) while there's 10752 CUDA cores (up from 10496 CUDA cores), 84 RT Cores (up from 82 RT Cores) and finally: 336 Tensors/TMUs (up from 328 Tensors/TMUs).

Watch how a black hole destroys stars in this supercomputer simulation

Adam Hunt | Science, Space, Health & Robotics | Mon, Nov 29 2021 5:45 AM CST

Researchers have published a new study in The Astrophysical Journal, simulating tidal disruptions and analyzing their dependence on stellar and black hole mass.

Watch how a black hole destroys stars in this supercomputer simulation 01 | TweakTown.com

Using supercomputer simulations, the research team modeled the outcome of eight different stars approaching a black hole with a mass of one million times our Sun. All of the stars are stretched and deformed by the gravitational forces of the black hole, undergoing spaghettification, with gravity destroying some entirely. When destroyed in a "tidal disruption event," the star is pulled apart into a long stream of gas and absorbed by the black hole.

The simulations are the first to combine realistic stellar density models with the physical effects of Einstein's general theory of relativity. Simulated stars had masses ranging from one-tenth to ten times the mass of the Sun. The team found that the star's survival depends more on its density than its mass alone.

Trees are greening sooner than they should be, and new data shows why

Adam Hunt | Science, Space, Health & Robotics | Mon, Nov 29 2021 5:05 AM CST

Lin Meng won the grand prize for 2021's Science & SciLifeLab Prize for Young Scientists for her research into how city environments impact tree phenology.

Trees are greening sooner than they should be, and new data shows why 01 | TweakTown.com

"Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonal and interannual variations in climate, as well as habitat factor," according to Wikipedia. Meng set out to determine how global warming and bright artificial lighting conditions in cities changed when trees started growing leaves in spring.

Previous research has shown that higher temperatures impact vegetation growth in cities, so the following question is how global warming affects that. Meng analyzed satellite data spanning 2001 to 2014 and 85 cities in the United States to find when trees began growing leaves. Trees "greened up" an average of six days earlier and were responding more rapidly to climate change in urban areas than in rural areas.

The SE range of in-ear headphones has a professional form factor perfect for live performers and studio monitoring, with wires arching up and around the ear to trail away behind the body subtly. All of the headphones in the range have wires which can be disconnected at the base of each earpiece, so you never have to worry about binning any of them due to broken cables, which is super reassuring given the cost of the higher-end offerings.

This interchangeability also enables Bluetooth via an accessory Shure also sells. As you opt for more expensive options, more drivers are added to each earpiece, for up to four per earpiece, dedicated to different frequencies for detailed and expansive sound separation.

"It was as flawless a docking as you can have," said Rob Navias of NASA.

Prichal joined with Russia's Nauka module aboard the ISS at 15:19 UTC, slightly ahead of schedule, with the docking hooks closing at 15:25 UTC. The module arrived with around 2,200 pounds (1,000 kilograms) of cargo and supplies for the crew aboard the ISS.

The Prichal module expands the docking capabilities of the ISS, adding six new ports for the Russian portion, with five of them available for newly arriving spacecraft. It can also transfer fuel to Nauka, the module it has docked to after Progress 78, the previously docked spacecraft, left to make room for Prichal's arrival.

Remnant magnetism may be to the key to finding hidden meteorite sites

Adam Hunt | Science, Space, Health & Robotics | Mon, Nov 29 2021 3:45 AM CST

A crater may disappear long after a meteorite impact, but a new method of finding impact sites despite this has been uncovered.

Remnant magnetism may be to the key to finding hidden meteorite sites 01 | TweakTown.com

Gunther Kletetschka of the University of Alaska Fairbanks Geophysical Institute has identified the significantly reduced level of natural remnant magnetization in rock as the key to defining a meteorite impact site. Rocks naturally have 2-3% remnant magnetization, referring to the number of magnetic mineral grains they contain, typically magnetite, hematite, or both. When collecting samples from the Santa Fe Impact Structure in New Mexico (pictured above), Kletetschka found they contained less than 0.1% magnetism.

Kletetschka determined that during a meteorite impact, the plasma created and changes in the electrons within the atoms of the rocks being struck decreased their magnetism. The Santa Fe Impact Structure consists of many shatter cones, which are believed to form only when rock is subjected to high pressure and high-velocity shockwaves, for example, a meteorite impact. Before these telltale shatter cones are uncovered, this discovery allows scientists to identify an impact site that has eroded and become unrecognizable or define the extent of an already identified impact site.
