How wide is a processor?

How wide is a processor?

Processors such as the Pentium 4 and Athlon XP are 32-bit processors because their internal registers are 32 bits wide, although their data I/O buses are 64 bits wide and their address buses are 36 bits wide (both wider than their predecessors, the Pentium and K6 processors).

What is bus width?

Bus width refers to the number of bits that can be sent to the CPU simultaneously, and bus speed refers to the number of times a group of bits can be sent each second. A bus cycle occurs every time data travels from memory to the CPU. Latency refers to the number of clock cycles needed to read a bit of information.

What is HT bus speed?

HyperTransport transfers two data per clock cycle, a concept also known as DDR, double data rate. Thus, with socket 754 processors, the HyperTransport bus can work up to 800 MHz or 3,200 MB/s.

What is HyperTransport bus?

A HyperTransport (HT) bus is a bus technology developed by AMD Inc. HyperTransport is packet-based, and it sends data in a packet that consists of 32-bit words. It also has power management and is compliant with advanced configuration and power interface specifications.

What is the average size of a CPU?

Types of CPUs Nowadays most desktop computers use either 32-bit CPUs or 64-bit CPUs. The instructions in a 32-bit CPU are good at handling data that is 32 bits in size (most instructions “think” in 32 bits in a 32-bit CPU).

What is processor and different types of processor?


S.NO Processor Power
1 Intel Pentium 111 The power of this processor is 97 W
2 IBM PowerPC 750X The power of this processor is 5 W
3 MIPS R5000 NA
4 StrongARM SA-110 The power of this processor is 1 W

What is width and size of a bus computer?

A computer bus (often simply called bus) is part of most computers. The size or width of a bus is how many bits it carries in parallel. Common bus sizes are: 4 bits, 8 bits, 12 bits, 16 bits, 24 bits, 32 bits, 64 bits, 80 bits, 96 bits, and 128 bits. Computers use such buses to link: CPU to on-board Memory.

How do you measure bus width?

How do you calculate address bus width?

  1. Total Addressable Memory = (2^address bus width) * Data bus width.
  2. IE a machine with a 16 bit Data Bus and 32 bit address bus would have.
  3. (2^32)*16 bits of accessible storage.
  4. or 8GB – Do the math yourself to prove it.

What does HT refers to in AMD processors?

HyperTransport (HT), formerly known as Lightning Data Transport (LDT), is a technology for interconnection of computer processors. HyperTransport is best known as the system bus architecture of AMD central processing units (CPUs) from Athlon 64 through AMD FX and the associated Nvidia nForce motherboard chipsets.

What is the difference between hyper threading and HyperTransport?

What is the difference between hyperthreading and hypertransport? Hypertransport has to do with the connection between the processor, memory and pci bank. Hyperthreading is the ability for the processor to run theads in paralell.

What is QPI processor?

The Intel QuickPath Interconnect (QPI) is a point-to-point processor interconnect developed by Intel which replaced the front-side bus (FSB) in Xeon, Itanium, and certain desktop platforms starting in 2008. It increased the scalability and available bandwidth.

What are the CPU sizes?

How many bits does the address bus have?

All PCs has at least 33 bits address buses and can use 8 G byte memory Some (high end) PCs has more than 34 or 35 bits address bus and can use maximum 16 or 32 GBytes memory

Is the HyperTransport bus only for AMD processors?

This is probably where a lot of misconceptions and mistakes regarding HyperTransport are said and written. The HyperTransport is a bus created by a consortium comprised of several companies including AMD, NVIDIA, and Apple. This bus can be used on several applications, and it is not limited to AMD processors.

Can a HyperTransport bus operate under different clock and width configurations?

The HyperTransport bus can operate under several different clock and width (i.e., the number of bits that are transmitted per time) configurations. This is probably where a lot of misconceptions and mistakes regarding HyperTransport are said and written.

What is the effect of the width of the data bus?

The width of the data bus determines the amount of data transfered per memory transfer operation The wider (= more wires) the the daate bus, the more data you can transfer per time unit (second) That will result is a faster running computer
