DATE:2017-07-25

In the official Intel price list, the characteristics of the 12-core Core i9-7920X processor were described rather succinctly : the base frequency of 2.9 GHz and the level 16.5 MB cache were added to the number of cores and streams.  Naturally, present in this document and the price of $ 1,189 per unit, which against the background of competitive proposals did not look very convincing.  The AMD Ryzen Threadripper 1920X processor with 12 cores not only operates at a higher frequency of 3.5 GHz, but also costs $ 799.

Colleagues from the Polish site PurePC published a screenshot of CPU-Z, which reveals additional characteristics of the processor Core i9-7920X.  At least, the engineering model confirms the base frequency of 2.9 GHz and the TDP level is not more than 140 W, and also the cache volume of the third level is 16.5 MB.

By the way, each of the 12 cores has 32 + 32 KB of the first level cache, and 1 MB of the second level cache.

POSTER: computer news   ||    TOYOTA PROMISES TO DEVELOP AN ELECTRIC CAR, CHARGED IN A FEW MINUTES

DATE:2017-07-25

The above-mentioned photo of the gasoline version C-HR crossover should not show the appearance of the first Toyota electric vehicle, which the company will start to produce in China for the local market in 2019.  Simply the future electric vehicle can use some of the nodes and assemblies of this platform, abandoning the internal combustion engine.  Large automakers in recent years are actively using flexible modular platforms that allow the production of a wide range of models with a high degree of unification.  This not only saves time for the development of new models, but also helps reduce production costs.

Note that the first electric vehicle Toyota for the Chinese market will use traditional lithium-ion batteries, but the "second pancake" in the form of a more promising model of electric vehicle will not only use the new platform, but will also receive new type of battery .  In any case, Reuters reports with reference to one of the Japanese newspapers.  According to the publication, Toyota hopes to start the production of an electric car with battery cells using solid-state electrolyte in 2022.  One of the advantages of a new type of battery is their ability to fully charge in just a few minutes against a few hours of traditional lithium-ion batteries.  At first, a new electric vehicle will be offered in Japan.  Apparently, it is the volume of battery output that will be the determining factor in the pace of its global expansion.  New batteries will also provide an increase in range on one charge, in addition to accelerating the charging process.

In the meantime, as Bloomberg explains, the business on the American market is not doing very well with the first Toyota production car on hydrogen fuel cells.  If 28 "hydrogen stations" were created on the territory of California, then on the east coast of the USA their construction did not even begin.  This prevents the company from commencing the sale of Mirai in the respective states.  The partners involved in this process are concerned not only with the relevance of such stations, but also with their fire safety.  In the first half of the year, Toyota managed to sell only 708 copies of Mirai throughout the United States.  Stored under high pressure in a special cylinder of hydrogen allows the car to travel about 500 km, the refueling takes several minutes, and as an exhaust, water vapor is generated.  In a power plant, hydrogen is used to generate electricity, which feeds the traction electric motor.  It is the possibility of quick fueling, according to Toyota, should attract to Mirai those who would like to drive "on electric traction", but considers electric vehicles not too convenient to operate.  It should be added that the production of hydrogen on an industrial scale is still too expensive to provide the owner of Mirai with compelling fuel economy.  Nevertheless, Toyota does not intend to give up its initiative yet.

TOYOTA PROMISES TO DEVELOP AN ELECTRIC CAR, CHARGED IN A FEW MINUTES

POSTER: computer news   ||    SOME ELECTRIC VEHICLES TESLA MODEL S ARE EQUIPPED WITH MORE CAPACIOUS BATTERIES

DATE:2017-07-25

As noted profile resources, with the advent of Tesla's younger model 3 in the range of electric vehicles, the Tesla Model S traction battery can be reformed - in any case, the initial version with a battery of 75 kWh and a single-axis drive will be removed by the end of the year.  Not so long ago Tesla Model S was offered in the version with a battery capacity of 60 kW h, which could be unlocked .

Electrek website notes that among the fresh samples of Tesla Model S and Model X delivered to Norway there were at least six pieces equipped with a traction battery with a declared capacity of 85 kWh.  Note that earlier this modification of the Tesla Model S was offered officially, until it gave way to the option with a battery capacity of 90 kWh (already discontinued), but in this case we are talking about electric vehicles Tesla Model S 75, Model S 75D and Model X 75D.  In fact, the actual capacity of their battery is higher than the one declared at the time of purchase.

At the same time, there are no proposals on the Tesla website for activating an additional 10 kWh,.

It can be assumed that after entering the market of Tesla Model 3, whose bundle of traction battery capacity has not yet been announced, the company will raise the "lower battery capacity bar" for the Tesla Model S and Model X, and options with a 75 kWh battery will be abolished Completely.

POSTER: computer news   ||    AMD COUNTS ON THE LONG LIFE OF THE 7-NM PROCESS TECHNOLOGY

DATE:2017-07-25

AMD company  can be considered one of the few who have already tasted the 7-nm process technology.  Processors Zen 2 are designed taking into account the 7-nm production technology, which makes them a new level of requirements.  This is a serious challenge, AMD's chief technologist Mark Pepermaster (Mark Papermaster) admitted in an interview to the Internet resource EE Times.  The company had to literally double its efforts and resources aimed at designing solutions with the norms of 7 nm.  And the technical process with these production standards will have a very long life, approximately, like in the 28-nm process technology.  Processors Zen 3 will also use a 7-nm process technology.

Go from 14/16 nm to 7 nm - this is how to jump in time from metal compounds in chips to copper connections.  This is a small revolution.  But this made it necessary to revise almost all the stages of design.  Transistors have to be connected "in a different way", also another construction of blocks is required.  In addition, the complexity of the work has increased many times because of the need to use four photomasks instead of two for the production of critical layers.  The reduction in the cost of production can be expected no earlier than after 2019, when EUV-scanners start operating at the manufacturing enterprises.  

Scanners with a wavelength of 13.5 nm by GlobalFoundries and TSMC (AMD's production partners) are planning to launch into commercial work in 2019.  In the first year, hardly any breakthrough is expected, but in 2020-2021 the effect of switching to EUV lithography can be felt in full growth.

Another alternative to reduce the cost of production of complex solutions should be the method of inexpensive packaging of several chips in a single case.  In the future, the industry seeks vertical (stack) structures using end-to-end metal connections such as TSVs.  Placement on one substrate of the processor (GPU) and memory of the HBM type is considered expensive at cost.  This is the so-called 2.5 D technology. The alternative is 2.1 D packaging, when the substrate and crystals are filled with sealant, turning into one housing - not yet suitable for the production of computer central and graphics processors.  Therefore, AMD developers urge manufacturers to adapt this type of packaging to processors and see in it the possibility to continue the work of Moore's law.

Fortunately for AMD, a similar type of packaging is the Integrated Fan Out Wafer-level Package (InFO-WLP) - practiced by TSMC.  For example, the latest Apple processors are packed with this method.  There is a non-zero probability that TSMC will be able to adapt the InFO-WLP packaging for the release of AMD solutions.

Finally, AMD encourages developers of software tools for designing chips to make maximum efforts to optimize packages for designers.  According to AMD, software for design does not fully use the parallelism in applications.  This is all the more offensive, because AMD has prepared 32-core processors with support for 64 threads each.  The complexity of projects is growing at a horrendous pace, and the tools are not improving as quickly as one would like.
