5. Active Participation
HyperTransport technology does not allow the system to take part in the processing of data actively. Its service and functions are limited to carrying data to and from quickly.
On the other hand, the hyperthreading technology affects the overall performance of the CPU as well as the computer system on the whole with its active participation in data processing.
HyperTransport technology is transparent to the system and can be used by any and every program, app and software of a computer system.
On the other hand, hyperthreading technology is invisible to the platform and creates an illusion of presence of a higher number of processors to the operating system.
It is useful only when you run more CPU intensive tasks at the same time and even while video editing and gaming.
Which is More Useful – HyperTransport or Hyperthreading?
Typically, both hyperthreading and HyperTransport have a direct effect on the overall performance of the computer system and therefore both are equally useful.
Ideally, these two are complementary technologies and certainly not competing ones.
Moreover, it is not possible to compare these two technologies directly and therefore it can be safely said that both these technologies are very helpful to the respective platforms.
Nevertheless, hyperthreading is only useful if the CPU has multiple cores in the system. It will increase the number of threads and therefore allow it to run more of them at once.
This technology of Intel allows the CPU to do two things at a time by creating virtual processors within a processor which will speed things up and help the users in multitasking.
Therefore, the CPU will always have additional processors on standby as and when required to process any data or instruction quickly.
It uses the additional registers of the CPU for that. These are actually the chips inside the system that help in managing data and instructions but are not used all the time.
It helps in improving resource management without needing any additional computational power from anywhere else.
This actually creates an illusion to the operating system, programmer and user thinking that everything went in and emerged in an orderly manner and in a sequential stream.
In the modern processors the out-of-order architectures actually do not execute any instruction or code sequentially or in the order these are written. These are called OOE or Out-of-Order Execution architectures.
They take in the codes altogether and, if possible, reschedule them in a proper order of instructions.
This helps in using minimum resources of the processor to execute them. Everything is then arranged back in the original order while writing the results out to the memory.
The actual order of execution of the instruction of the program is known only to the CPU.
This novel concept of hyperthreading technology of Intel delivers faster response times by enabling the processor to use the on-die resources that would have gone wasted or would have remained idle otherwise.
On the other hand, the significance of the HyperTransport technology is that it performs more like a bus for the CPU. It can be said that this is the specific technology found in a few CPUs that acts as an interconnect.
Typically, if a CPU has multiple cores and memory it will also have multiple memory controllers.
Therefore, when a particular core or CPU needs to access the memory which is controlled by a dedicated controller, the HyperTransport interconnect will be more useful for that matter.
In theory, it will enhance the memory functions and offer more accessibility with larger bandwidth in comparison to situations when it has to be done through a bus with limited bandwidth thereby resulting in significant bottlenecks.
This particular AMD technology actually reduces the number of buses for the processor to use in a system.
This expedites and improves the data transfer process and communication between the CPU and different components on the motherboard of the computer system.
It also increases the overall system performance this w
