A NEW SOC FOR MAC

Apple announced its new chip for its new MacBook line up . On November 10,2020 Apple announced the new M1 chip for upcoming mac products.

M1 chip is similar to processor used in mobile Phones. Qualcomm also introduced the similar type of chip named as 8cx for laptop on 2018.

M1 chip features:

8 Core CPU , 8 Core GPU, 16Core Neural Engine.

M1 has 16 Billion Transistors which is built on 5 nm fabrication node. This makes the chip as more power efficient.

Apple Claims the 8 Core CPU is 3.5x faster than intel 1.2GHz quadcore i7 processor and 8 Core GPU can handle 25K threads at the same time. 16 core Neural Engine can run 11 trillion operations per second.

Apple also introduced three Mac products built using this M1 chip MacBook Air , MacBook Pro 13 , Mac Mini.

Memory for this computer built internally inside the M1 chip, so when you purchasing the laptop you should be careful of choosing the memory configuration because you didn’t have a option to increase the memory once you have bought these products.

Apple said all of his mac products will be shifted from intel based chips to apple based SOC within next two years.

Apple may introduce new Soc chip for mac book pro 16 in feature this will be more powerful than M1 Chip to handle heavy task.

Note: This transition help us to use our iPhone and iPad apps in Mac computer.

Our Sun next Solar Cycle

Our Sun next solar cycle started on Sep2020.


Solar cycle happen every 11 years. This solar cycle calculated based on minimum and maximum solar activity. During this period the sun flip the magnetic field from north to south so these leads to heavy solar activity and when sun reaches it peak activity we can see many Sun spots.


Sunspots are usually black in color in visible light, but when we see the Sun in ultra violet wavelength we can see the intensive magnetic field activity .


Why we need to monitor the Solar cycle?

During the Sun’s peak active period large amount of coronal mass ejection will happen , so during this time it will directly affect the earth and heats up the earth atmosphere that will cause damage to electric transmission , pipelines ,communication towers and satellites. Also this huge radiation affect the astronauts in space station.


So Continuous Monitoring will help us to understand pattern of the peak solar activity , Using that we can prevent the electronic equipment by turning off the device during the peak solar period. Also we warn the astronaut not to do the space walk during that period.

Usually peak solar activity happens in middle of the solar cycle. Last one happen at 2012.


This information Updated by Nasa on Sep18 and followed by they Published the video on YouTube. Please check the following link to view discussion between the solar experts:


note: Last major corona mass ejection happen at 2012 and we detected this event only after 9 days from the event.

AMD New Graphics Card

AMD announced three new Graphics Card on Wednesday( 28/10/2020).
Radeon 6900 XT , 6800 XT, RX6800 These Graphics Card are direct competition to Nvidia Graphics Processor which was currently available( RTX3090 , RTX 3080)
These processor was built using TSMC 7nm node and it has 26.8 billion transistors .
These processor are built using new RDNA 2 Architecture these leads to 65% increase in power per watt ratio when compare to previous Generation Architecture.
Feature of this new Graphics processors:
Cache : AMD named their cache as AMD Infinity Cache . They have implemented 128MB cache with 256bit 16Gbps bandwidth this will increase the performance for GPU and reduce the latency while gaming.
AMD Standard Access memory: This feature will help the CPU can access the GPU memory directly. While this feature only possible if you going to connect AMD GPU with AMD CPU.
These processor also support the Direct x 12 and Direct X ray tracing . Ray tracing is possible by Hardware Ray Accelerator special compute unit implemented inside the chip.
AMD GPU Processor information:
6900 XT :
Compute units – 80 , Game Clock – 2015MHz, Boost Clock – Up to 2250 MHz
6800 XT:
Compute units – 72 , Game Clock – 2015MHz, Boost Clock – Up to 2250 MHz
RX6800
Compute units – 60 , Game Clock – 1815MHz, Boost Clock – Up to 2105 MHz
All these three GPU has same,
Memory – 16 GB, Memory Interface – 256 bit , Infinity Cache – 128MB
