POSTER: computer news   ||    THE NEW TYPE OF THE SKYLAKE-X PROCESSOR BUS CAUSED A DECREASE IN PERFORMANCE IN GAMES

DATE:2017-07-11

The abundance of reviews of Skylake-X processors on foreign resources allow   to quickly reveal the "weaknesses" of new products.  For example, in the material of the German site GameStar.de , the strange proportion of Core i9-7900X processor speed in games compared to representatives of older families - Broadwell-E and Haswell-E,  alarmed.  Even with an increased number of cores and a higher frequency, the Core i9-7900X turned out to be slower than the older processors.

The author of the review asked Intelrepresentatives for clarifications  , and they admitted that this effect gives a new bus "cellular" type, which is used to connect the blocks inside the Skylake-X processors.  Broadwell-E processors, in turn, use the old ring bus, and in this type of computational loads it manifests itself better.  Recall that in Skylake-X, Intel refused to use the same type of bus, because it did not allow to scale the number of cores within reasonable limits of power consumption.

However, Intel makes it clear that in a number of applications the new bus provides a speed increase.  Changes in the cache structure in Intel's comments are not mentioned, although our colleagues are inclined to believe that this factor influenced the performance of Skylake-X in games.  So, the volume of the third level cache has decreased, and the amount of cache of the second level available to each core has increased from 256 KB to 1 MB.

POSTER: computer news   ||   AVX512 THE PERFORMANCE OF CORE I7 AND CORE I9 SKYLAKE-X GENERATION IS VERY DIFFERENT

DATE:2017-07-11

According to source, the engineering samples of  Core i7-7820X and Core i7-7800X processors had the same level of performance with the Core i9-7900X in the tests using the AVX512 extensions, but their serial versions kept active exactly half of the blocks responsible for the performance in this area.  Thus, the serial Skylake-X processors with six and eight cores are weaker than the 10-lead flagship in tasks using the AVX512.  I must say that there are not so many of them yet, but it is consideredthat they are concentrated in the professional application sphere  , and the same games do not affect the problem.

The authors of the study believe that Intel will encourage professionals to purchase Skylake-EP server-class processors, where such a restriction will not exist.

POSTER: computer news   ||    LUCID MOTORS MANAGED TO OVERCLOCK THE ELECTRIC CAR TO 378 KM-H

DATE:2017-07-11

The company Lucid Motors published a video that demonstrates a new speed record for an electric vehicle.  Specially prepared version of the Lucid Air accelerated to 378 km / h, improving its own April record at 28 km / h.  It should be noted that the developers have removed the software limitations that can save the traction battery and the motor from overheating.  In addition, in comparison with the previous experiment, they modified the software controlling the air suspension, and also enhanced the cooling of the front electric motor.

 

The interior of the test electric vehicle was different from the production one - the lining and all the details of the cabin for the sake of weight reduction were removed, but a tubular safety cage was provided to protect the pilot.  It is noteworthy that the serial version of the Tesla Model S in its fastest version is gaining speed of 249 km / h.  Of course, the serial version of Lucid Air demonstrated in the roller of speeds on public roads will not reach, but similar experiments are interesting from the point of view of electric transport potential  .

POSTER: computer news   ||    FOR THE ORIGINAL HALF-LIFE WAS RELEASED AN OFFICIAL PATCH

DATE:2017-07-11

Valve is able to present surprises.  The company does not forget to patch up its old games.  More precisely, one of  first games - Half-Life.  The original project, which was born almost twenty years ago, acquired a new "patch", which, imagine, makes some more corrections.  Before that, the game received a beta version of the patch in 2013 - that is, not so long ago.

A new "update" makes adjustments to the console, corrects minor defects and even corrects a bug that could occur with a rapid change of weapons.  The update is already available for automatic download on Steam.   Valve still cares about the technical condition of their old games.
