By | May 13th, 2019|Categories: TechRadar|

We all know the feeling: you've saved up all your dollars and cents in order to buy that state-of-the-art new television you've had your eye on, and shortly after you've purchased said TV, a new wave of next-generation TVs is announced which promises to outperform your set in absolutely every way.

Where currently in that situation with 4K vs 8K TVs, and while having widespread access to true 8K UHD content is a long way off (we’re talking years here), many TV manufacturers are hoping that the impressive upscaling and greater clarity offered by this first wave of 8K sets will be enough to convince enthusiasts that they can already benefit from owning one.… Read the full article

Walter Schofield, the company’s CEO, told me that in addition to a few new products recently introduced, many more are just on the horizon. The new products—and the new marketing push—are based on two recent technical advances. The first, iBias, which was introduced by Krell in 2014, is a sliding-bias scheme that ensures there’s always a positive bias for both phases of the waveform.… Read the full article

By | May 13th, 2019|Categories: AV Hub|

 Launched at High End 2019 in Munich, Ortofon’s new flagship phono cartridge, the MC Anna Diamond, is similar to the previous Anna MC model except that this new model has a cantilever made of diamond, instead of boron.

The improvements Ortofon has realised by using a diamond cantilever have redefined the boundaries of analogue reproduction, enabling greater inner detail, subtlety, and depth like never before,’ said Sam Encel, of Interdyn, which distributes Ortofon in Australia. ‘It also enables the best interface with the Replicant diamond stylus, which, because it’s the closest in shape to the cutting stylus of any stylus profile type, can trace with unparalleled accuracy.Read the full article

The dark web represents only a fraction of the rest of the internet

By | May 13th, 2019|Categories: TechRadar|

The dark web is often portrayed as a hidden corner of the internet where cybercriminals exchange information and plan cyberattacks but how does it compare to the rest of the internet?

To answer this question, Recorded Future analysed 260,000 onion pages to better understand the reach of the Tor network from a starting set of onion sites pulled from public lists and its own content. The threat intelligence company quickly realized that the dark web is actually tiny when compared to the “clear web” used by consumers and businesses.… Read the full article

AMD Radeon RX 640 re-branding for Polaris GPUs hinted in new drivers

By | May 13th, 2019|Categories: TechRadar|

While we continue to wait for AMD to push graphics processors forward with Navi and its 7-nanometer architecture, a leak is suggesting that may not be the only things AMD is preparing. A new graphics card name was discovered in AMD's Adrenalin 19.4.3 graphics drivers by a TechPowerUp reader.

The newly identified card is a Radeon RX 640. This would put it on the lower end of the performance spectrum per AMD's naming convention. But, this would also suggest it's neither a Vega nor Navi GPU.… Read the full article

Deutsche Telekom and Ericsson push microwave link over 100Gbps

By | May 13th, 2019|Categories: TechRadar|

After demonstrating that it was possible to take wireless backhaul to 40Gbps earlier this year, Deutsche Telekom and Ericsson have returned to take a 1.5 kilometre link to 100Gbps.

The trial was once again conducted at the Deutsche Telekom Service Center in Athens and it utilized Ericsson's Mini-Link 6352 microwave solution. To achieve such improved speeds, the recent trial used 8×8 line-of-sight Multiple-Input Multiple-Output in a 2.5 GHz channel within the 70 to 80GHz range.

The telecom and network hardware manufacturer said that transmission rates were consistently above 100GBps with a peak speed of 140Gbps which means that the technology could be used in 5G networks.… Read the full article
