Only for the wealthy, exactly 16 years ago, Intel’s extreme gaming processors appeared
With an FSB bus frequency of 800 MHz, it operated at a speed of 3200 MHz. Additionally, the “stone” was equipped with 2 MB of cache in the third level.
On sale Pentium 4 Extreme Edition appeared only in November 2003.
These models were positioned as competitors to AMD Athlon 64 FX. A little later, an additional model of the Gallatin family appeared, operating at a frequency of 3.4 GHz. The TDP level of the device was decent even by today’s standards 111 W. The appearance of hot chips gave impetus to the development of a new type of components. efficient processor coolers.
Since then, an extreme series of central processors has appeared. As for Pentium, from now on, only budget solutions are issued under this brand.

September 17, 1922 in Moscow, the first radio concert. It was on this day for the first time that a phrase was heard, which later became winged: “Attention! Moscow says! ”On the radio, the USSR People’s Artist of the USSR Nadezhda Obukhova performed the song“ Do not tempt me without need ”. Artists of the Bolshoi Academic Theater Antonina Nezhdanova, Ksenia Derzhinskaya, Vasily Kachalov and other famous performers also took part in the concert. Broadcasting was conducted from the Central Radiotelephone Station named after the Comintern on Shabolovka.

On September 17, 1955, a Convair NB-36H aircraft, equipped with a nuclear power plant (YaSU), first flew into the sky. Talk about creating such an aircraft was conducted back in 1941. In particular, an article by R. Langer on the use of uranium as a fuel for vehicles, allowing them to stay in the air for several days, was published in the American magazine Popular Mechanics. The main obstacle to promoting such mechanisms was the need to provide a safe environment for crew members and the environment. After only two years, the US special services took up this problem.
Because of the Manhattan nuclear program, they returned to the development of the atomic bomb only in 1947. The development was entrusted to Fairchild. Some experiments were made. So, a radioactive installation was placed on a B-29 airplane in the bomb bay. But the experiments were unsuccessful. The task was not completed, and with Fairchild the contract was broken. At the same time, the US Air Force expenses for the year exceeded 10 million dollars.
They returned to the development of the atomic bomb only in 1951. A competition was held, as a result of which four companies were allowed to develop the aircraft. General Electric and Convair began designing an open-cycle nuclear aircraft, and Pratt Whitney and Lockheed Martin. closed loop.
Based on the heaviest at that time Convair B-36 bomber, the take-off weight of which was 186 tons. At the rear of the bomb bay, a test reactor with a capacity of one megawatt, a diameter of 1.2 m and a weight of 16 tons, operating on fast neutrons, was placed. Uranium dioxide acted as fuel. An open cycle meant that the reactor was cooled by air entering the bomb bay through special nozzles. Heated air was thrown overboard. That is why an open cycle nuclear installation is considered less environmentally friendly than a closed cycle. In the second case, the reactor was cooled by a closed water circuit (based on sodium). However at pratt Whitney and Lockheed Martin are having trouble designing fan motors.
The protective capsule in which the pilots were located was made of lead and rubber, and the windows of the atomic aircraft were made of lead glass 30 cm thick.
After the flight, the nuclear warhead was dismantled and placed in a special underground bunker. With a wingspan of about 70 meters, the Convair NB-36H developed a top speed of 676 km / h.
The first flight of the aircraft was completed in 1955. During the test, the aircraft made 47 elevations to the sky. However, in March 1957, the aircraft was completely decommissioned.
