Difference Between PowerPC and Intel

Apple changed PowerPC to Intel in the year 2006. This transition of the microprocessor made the public take a choice between these two processors. PowerPC is developed by major three companies Apple, IBM, and Motorola.

PowerPC was mainly used by Apple products. It had brilliant performance and faster than PowerPC.

PowerPC vs Intel

The main difference between PowerPC and Intel is PowerPC is a microprocessor that uses a RISC instruction set, whereas Intel uses a CISC architecture set. PowerPC is developed by Apple, IBM, and Motorola. Intel uses CISC architecture which has huge different complex instructions.

PowerPC vs Intel

PowerPC is a cheap microprocessor that has RISC architecture. The processor is busy all the time in RISC architecture.

PowerPC has a broad range, simple design, good architecture as features. It has a 64-bit architecture. The mode can be changed at any time. 8-bit bytes are taken by memory.

Apple made a huge change when it switched from PowerPC to Intel. Intel is based on Nehalem-based architecture. Intel chips are more efficient.

It had brilliant performance and faster than PowerPC. It supports hyperthreading in many devices.

It has the most advanced technology used in it. The chips undergo numerous tests so that it proves that the chip can get through all types of circuits.

What is PowerPC?

PowerPC supports RISC architecture. It keeps the processor very busy every time. Floating-point registers have separate sets.

Halfword has two consecutive bytes, the word is of four bytes, and doubleword is of eight bytes. Virtual Address Space can be used to write PowerPC programs.

Registers are present in the architecture. Data and addresses can be stored and manipulated using general registers.

It consists of 32 general registers.The floating-point unit is present for computation. There is a different type of allocations which include 8, 16, 34 and 64-bit binary numbers.

It has some instruction sets in which there are rules to follow. Decode the instructions by the first 6 bits, which are called primary opcode.

There are remaining contain fields that hold specifiers, immediate, and many more reserved bits. The structure is very complex in PowerPC.

It has two types of approaches for input and output operations. One is through address space, and the other through memory management.

What is Intel?

Intel has changed rapidly in the last fourteen years. It is an American corporation company situated in California.

The power consumption in Intel is very high. The QPI (Quick Path Interconnect) allows faster communication with the CPU.

Apple made a huge change when it switched from PowerPC to Intel. Intel is based on Nehalem-based architecture.

Intel chips are more efficient. It had brilliant performance and faster than PowerPC. It supports hyperthreading in many devices.

Fabrication is the process in which computer chips are made. The chips undergo numerous tests so that it proves that the chip can get through all types of circuits. It tested several times under different procedures that it makes it suitable to deliver power and fit for all kinds of connections.

After all the test has been made, it is placed in the position in the motherboard or other devices. It ensures quality.

Main Differences Between PowerPC and Intel

  1. Intel processors work faster than PowerPC.
  2. The clock rate of Intel is 3.47 GHz, whereas the clock rate of PowerPC is 1.6GHz.
  3. Intel has high power consumption as compared to PowerPC.
  4. PowerPC is based on Power-based architecture, whereas Intel is based on Nehalem-based architecture.
  5. PowerPC’s main feature is RISC computing, whereas Intel’s main feature is QPI technology.
