1. M1

(1). TSMC 5nm

Taiwan Semiconductor Manufacturing Company

Notes for industry

• Transistor Density: 180%
• Transistor Performance: 115%
• Power Consumption: 70%

(2). Architecture

Programmable Computer

Using instructions flow to control the Computer #### Examples:

CISC

ADD  $4, 14(%eax, %ebx, 8)

• Usage: Adding 4 to the data stored in memory: 14 + %eax + (%ebx * 8)

RISC

LOAD (%eax), %ebx
LOAD $4, %ecx
ADD  %ecx, %ebx
STORE %ecx, (%eax)

An Article from stanford (Cisc vs Risc)

• Reduced Instruction Set Computer
  • Fixed Instruction Format and Fewer Instructions
    • Faster to Encode and Decode
    • Require more Instruction Memory and Registers
    • Circuit is Simpler
  • Examples
    • MIPS, ARM, AVR
  • Often used in
    • Mobile Devices (Phone)
    • Less Power-Consuming Devices (Embedded device)
• Complex Instruction Set Computer
  • Instruction Takes Longer to Execute (Pipeline)
  • Larger Number of Instructions (Decode Hardware)
  • Examples
    • IBM System 360, x86, IA-32, AMD-64, x86-64
  • Often usde in
    • Large Servers
    • PC

(3). Apple

Comparing with Other Laptop Company

• Dell, Lenovo…
• Apple Has its own Ecology (Unique and Cannot Compete)

Comparing with Other Semiconductor Company

• Intel, TSMC…
• Apple can sell its products directly to its user (Maximum Profit)

The Comination fo Software and Hardware (For Specific Task)

My Concern

• 1. Desktop GPU and CPU (> 300W)?
• 2. Just for Specific Software (Logic Pro/ Final Cut Pro…)
• 3. Gamers?

2. Computer Architecture

• As long as everything goes well, not knowing what happens in the underlying level (or above) is not a problem.
