The performance of generation 11 core is different in two memory gear configuration modes

The 11th generation of core desktop processor has been put on sale. TPU has tested the memory part, and has made further discoveries. Let's share with you. First of all, in the theory part, the 11th generation core redesigned the memory controller, which is defined as the gear working mode, corresponding to the two settings of gear 1 and gear 2 in the BIOS. New discovery: the performance of 11th generation core is different in two memory gear configuration modes The gear 1 working mode is 1:1, that is, the ratio of CPU memory controller and memory working frequency is 1:1. The memory controller and memory work synchronously. In this mode, the maximum memory efficiency and the minimum memory delay can be achieved. Gear 2 mode is 2:1, the memory controller and memory work asynchronously. This mode reduces the frequency of the memory controller by reducing the frequency doubling of [...]

The impact of dinosaur extinct asteroids may have created today's Amazon rainforest

The formation of the rainforest on earth may have originated from the asteroid impact that led to the extinction of dinosaurs, a new study suggests. Using pollen and leaf fossils from Colombia, the researchers explored how asteroid impacts changed the tropical forests of South America. The impact of dinosaur extinct asteroids may have created today's Amazon rainforest The asteroid impact 66 million years ago not only led to the extinction of dinosaurs and other life forms, but also led to the replacement of ecosystems 66 million years ago, a 12 kilometer wide space rock hit the earth, causing great changes in the types of vegetation that make up these forests. The team reported their findings in the famous journal Science. "Our team examined more than 50000 pollen fossils and more than 6000 leaf fossils before and after the impact," said study co-author Dr. Monica Carvalho of the Smithsonian Tropical Institute [...]
