POSTER: computer news   ||    SONY AND IBM INTRODUCED HIGH-DENSITY MAGNETIC TAPE RECORDING TECHNOLOGY

DATE:2017-08-05

At the moment, the LTO-7 standard operates in the magnetic tape market.  LTO-7 cartridges can store up to 6 terabytes of uncompressed data and are characterized by a transfer rate of 300 MB / s.  Next year or even in a year, the LTO-8 cartridge standard will be introduced, which will double the capacity and data transfer rate.  But even today, developers of tape recording technologies have created a huge reserve for increasing the capacity of cartridges.  And this "stock" the other day was again replenished with a new development.

IBM and Sony jointly presented a number of technologies, thanks to which in the future it will be possible to produce a cartridge with a capacity of 330 TB.  The previous record was also installed in the laboratories, but then IBM worked with Fujifilm.  In 2015, the company's engineers created a film, magnetic recording heads and a signal system for recording on a tape with a density of 128 Gb / sq. In.  The technology promised to increase the capacity of cartridges to 220 TB.  The improved recording technology allows you to record on a square inch of tape already 201 Gb / in.

The improved tape Sony and IBM has received the lubricant developed by the scientists of the Blue Giant to cover the tape and to reduce the frictional force and wear of the working layer.  The grain for recording - a magnetic domain with a vertical magnetization - was able to be reduced to 7 nm.  This allow to reduce the working gap of magnetic heads based on the tunneling magnetoresistive effect from 90 nm to 48 nm.  The number of recording tracks increased from 181,300 to 246,200.

To record data at higher density and with increased speed, IBM developed an improved signal processing algorithm and finalized the mechanism for positioning the heads.  Samples of the new magnetic tape and drives for reading and writing data partners recently demonstrated in the work of the thematic conference Magnetic Recording Conference (TMRC 2017) in Japan.

POSTER: computer news   ||    AMD RADEON RX VEGA 64 RUNS THE RISK OF DEMONSTRATING HIGH PERFORMANCE IN MINING

DATE:2017-08-04

While fans of computer games and mining crypto mining argue, which of their favorite occupations is more ethical, the sellers of video cards are ready to earn on the weaknesses of both.  Producers secretly try to condemn the greedy part of the consumer audience, but this is some part of hypocrisy - they get their share of the income.  We already mentioned that the preparation of Radeon RX Vega for the start of sales took more time than we would like, precisely because of AMD's desire to create a large enough stock of ready video cards, which would suffice even with the possible interest from the "crypto-drivers".

Another "conspiracy theory" was born.  Although it is not entirely correct to estimate the real power consumption level only based on the TDP values ??and the recommended power unit's power, some hypocritical people believe that the Vega 10 energy consumption level is artificially overstated in order to raise the expenditure part of the "miners" budget, thereby reducing the attractiveness of these video cards.  Supporters of this idea do not give rest to the results of Radeon Vega Frontier Edition testing with underestimation of the nominal voltage.

One way or another, on the Web, rumors are circulating about the exceptionally high performance of Radeon RX Vega 64 in specialized applications for the production of Ethereum.  One source is a representative of a British store , consonant with our site, to which one of the partners of AMD provided such information.  Supporters of this theory, albeit in less frightening figures, are colleagues from the VideoCardz website.

Part of the validity of such fears is confirmed by AMD's intention to sell video cards of the Radeon RX Vega family in the form of incentive kits that imply discounts for the purchase of processors and motherboards.

AMD RADEON RX VEGA 64 RUNS THE RISK OF DEMONSTRATING HIGH PERFORMANCE IN MINING

POSTER: computer news   ||    AMD RYZEN THREADRIPPER 1920 WILL LIMIT THE VALUE OF TDP NO MORE THAN 140 W

DATE:2017-08-04

Officially, AMD has so far submitted only three Ryzen Threadripper models, more adapted to overclocking and bearing the letter "X" at the end of the designation, but the manufacturer's documentation contains references to their "close relatives" without the letter "X" in the designation of the model.  A cursory acquaintance with the tables of compatible processors in the performance of Socket TR4 on the sites of several motherboard manufacturers allows to state that the market will be released 12-core AMD Ryzen Threadripper 1920, which will have a lowered to 140 W TDP level.

The names of manufacturers of motherboards that have placed such information, we have not yet advertised for the purposes of excessive and meaningless conspiracy, but the rich history of persecution on their part does not leave us any other choice.

The Ryzen Threadripper 1920 processor is also disclosed. It works at 3.2 / 3.8 GHz instead of 3.5 / 4.0 GHz.  Accordingly, a less efficient cooling system will be able to handle it than prescribed for use with processors having a TDP level of not more than 180 W.

Note that the Ryzen Threadripper processors are based on the B1 stepping, and the server EPYC is attributed to the B2 stepping.  According to some reports, within the same family these steppings should not intersect.

POSTER: computer news   ||    INTEL LGA 2066 PLATFORM WILL NOT BE TOO HOSPITABLE TO THE FOLLOWERS OF SKYLAKE-X

DATE:2017-08-04

Yesterday's "Chinese revelations" about Intel 's plans focused on discussing how deceptive the company's promise to release Kaby Lake's successors in LGA 1151 design could be. However, these slides at the same time allowed us to make sure that the Intel X299 and the Socket 2066 platform up to the middle 2018 there will be no successors, and this is at least.

Does this mean that subsequent Intel processors of this price category will be able to work on existing motherboards with a LGA 2066 connector?

Colleagues from the site Bits & Chips say that it's not worth counting on, and the only likely candidates for compatibility with the Socket 2066 is the current revision are the processors Coffee Lake-X.  Their successors named Cannon Lake-X with socket Socket 2066 of the current revision will not be compatible.  Presumably, the conventions for generations  Intel processors are hypothetical, since they have not been publicly mentioned in the official plans of the company.

By the way, some Chinese sources specify that the 18-core Core i9-7980XE processor will be presented on October 18 this year.
